Referring to fig. 1, an embodiment of the present utility model provides a control system, which may include a thermostat 100, wherein the thermostat 100 is used to connect with heating and ventilation devices 500 and control the heating and ventilation devices 500.

In part, the control system further includes a terminal 200 and a gateway 400.

The terminal 200 may be any device or combination of devices having data processing capability and external communication capability, for example, it may be a mobile phone 201 as shown in fig. 2, however, other terminals 200 besides the mobile phone 201 may be other devices, for example, a computer, a car set, a smart watch, a smart VR device, etc., which is not limited in this embodiment.

The gateway 400 may be understood as any gateway 400 of any network, for example, any one of a WIFI network (router 401), a ZIGBEE network, and a bluetooth network (bluetooth gateway 402), and will be described mainly based on a WIFI communication manner in the following description.

Further, the gateway 400 may access the internet, so as to exchange data with other devices (e.g., the terminal 200, other external devices 600) accessing the internet. The gateway 400 may be a gateway device (e.g., a router 401, a bluetooth gateway 402) dedicated to the gateway, or may be another device having a gateway function, such as a speaker having a gateway function, a display device having a gateway function, a wall switch having a gateway function, or the like.

In some examples, the server 300 may be a cloud 301 (cloud server) and may perform data storage and processing functions.

In one embodiment, as shown in fig. 2, the gateway 400 is a WIFI gateway (i.e. the router 401), the corresponding network is a WIFI network, and the temperature controller 100 can join in the WIFI network after the network is configured, and access the internet through the router 401, so as to communicate with the cloud 301. The terminal 200 is a mobile phone 201, and the mobile phone 201 can access to the cloud 301 through cellular data, a wireless local area network and the like. Other external devices 600 (e.g., temperature and humidity sensors) may also access the cloud 301 through the corresponding bluetooth gateway 402 or router 401. Furthermore, the communication between the temperature controller 100 and the mobile phone 201, and between the temperature controller 100 and other external devices 600 connected to the cloud 301 can be realized through the cloud 301 as an intermediary.

The heating and ventilation device 500, i.e., heating, ventilation and air conditioning device, is used to create an indoor environment to meet comfort requirements of users for temperature, humidity, air quality, etc. The heating and ventilation device 500 is of various types, and the heating and ventilation device 500 according to this embodiment is the heating and ventilation device 500 supported by the temperature controller 100. In this embodiment, these heating and ventilation devices 500 are classified into valve type heating and ventilation devices (i.e., heating and ventilation devices controlled by a control valve, such as a fan coil type central air conditioner, a floor heating system, a valve type fresh air system, etc.) and protocol type heating and ventilation devices (i.e., heating and ventilation devices controlled by a signal, such as a protocol type fluorine machine central air conditioner, a 485 fresh air machine, etc.), according to the control modes. The manipulation that thermostat 100 can exert on these heating and ventilation devices may be, for example, but not limited to, controlling to enter a state such as turning on or off an air conditioner, turning on or off a floor heating, turning on or off a fresh air system, controlling to switch between states such as switching a cooling and heating mode of an air conditioner, switching on and off a fresh air system, switching on and off a floor heating, controlling to change an operating parameter such as adjusting a cooling/heating temperature of an air conditioner, adjusting a wind speed of a fresh air system, adjusting a temperature of a floor heating, and the like. The control of the valve type heating and ventilation equipment is realized by controlling the action of a valve of the valve type heating and ventilation equipment, and the control of the protocol type heating and ventilation equipment is realized by sending corresponding communication signals to the valve type heating and ventilation equipment. The specific control and control may be arbitrarily changed according to the type of the heating and ventilation apparatus 500 connected to the thermostat 100, without departing from the scope of the embodiment of the present utility model. Meanwhile, the following description of the operation of the heating and ventilation apparatus 500 by the thermostat 100 may be understood with reference to the above.

The existing heating and ventilation equipment can only rely on a dedicated control panel provided by each manufacturer to realize equipment management, and the dependence not only limits the freedom of selection of users, but also reduces the integral integration and operation convenience of the intelligent home system, because the equipment means that when the users install various heating and ventilation equipment at home, the equipment has to be frequently switched among a plurality of different control interfaces, and unified and smooth control experience cannot be enjoyed. In addition, in the control field facing protocol type heating and ventilation equipment, data communication standards adopted by various suppliers show remarkable diversity, and even among different brands or different models of equipment in the same supplier, the data conversion protocols of the equipment can be remarkably different, so that the difficulty of managing the heating and ventilation equipment in the same way through one temperature controller is increased. Therefore, an intelligent temperature controller solution capable of uniformly managing various heating and ventilation device types and compatible with various data conversion standards is sought, so that the device universality and user interaction experience are improved, and the intelligent temperature controller solution becomes very important.

Based on the above, the utility model provides a temperature controller control method, which endows the temperature controller 100 with strong compatibility, so that the temperature controller can not only control two types of heating and ventilation equipment in a valve type and a protocol type in a cross-domain mode, but also realize intelligent adaptation to the type of the protocol type heating and ventilation equipment in a breakthrough mode.

The following will explain various embodiments of the control method provided by the present utility model, and technical features of the various embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Referring to fig. 3, a control method of a thermostat is provided, which is applicable to the thermostat 100 in the control system, where the thermostat 100 supports multiple types of heating and ventilation devices 500, and includes at least a first type of heating and ventilation device 501 and a second type of heating and ventilation device 502, where the first type of heating and ventilation device 501 may be, for example, a protocol type heating and ventilation device, and the second type of heating and ventilation device 502 may be, for example, a valve type heating and ventilation device, and the control manners therebetween are different.

As can be seen from FIG. 3, the control method at least includes steps S1 to S3. Wherein:

S1, receiving a control command. The temperature controller 100 may be controlled in various manners, such as terminal direct connection control, cloud control, local control, etc. Furthermore, the control command may also have various sources, such as receiving a control command from the terminal 200 (mobile APP, smart speaker) through WIFI or bluetooth communication, and receiving a control command input by a user at a local interface of the temperature controller 100. The present embodiment classifies control commands into various types (e.g., first type of commands and second type of commands referred to in the following embodiments) for controlling the respective types of the heating and ventilation devices 500 according to the types of the controlled heating and ventilation devices to which the control commands are directed.

And S2, when a first type command is received, a corresponding control signal is sent to the auxiliary control module 3151, and a changeable data conversion standard is preset in the auxiliary control module 3151, so that after the auxiliary control module 3151 receives the control signal, format conversion is performed according to the currently set data conversion standard, the received control signal is converted into a data format which can be identified by the first type heating and ventilation equipment 501, and the first type heating and ventilation equipment 501 is controlled based on the converted data, so that control over the first type heating and ventilation equipment is realized.

S3, when a second type command is received, the output on-off module 32 is regulated to control the second type heating and ventilation equipment 502.

Specifically, in the process of using the thermostat 100, the user needs to set the data conversion standard in the auxiliary control module 3151 according to the first type of heating and ventilation device 501 connected to the thermostat 100, so that when the first type of command is received, the data format converted by the auxiliary control module 3151 can be successfully identified by the heating and ventilation device 500.

When a user controls the temperature controller 100 in various ways, if the control command is a first type command for the first type heating and ventilation device 501, the temperature controller 100 sends a corresponding control signal to the auxiliary control module 3151, and the auxiliary control module 3151 converts the control signal into a format which can be identified by the first type heating and ventilation device 501 according to a preset data conversion standard and sends the control signal to the corresponding device, so as to realize control of the first type heating and ventilation device 501. If the control command is a second type command for the second type heating and ventilation device 502, the thermostat 100 regulates the output on-off module 32 to directly control the second type heating and ventilation device 502.

According to the control method provided by the embodiment, the temperature controller 100 is allowed to support various types of heating and ventilation equipment 500, when a user is provided with various types of heating and ventilation equipment 500 at home, a control panel is not required to be specially arranged for each heating and ventilation equipment 500, the temperature controller 100 is made into a general temperature controller by the control method provided by the embodiment, the temperature control equipment configured by the heating and ventilation equipment can be replaced, intelligent control can be provided for the heating and ventilation equipment, for example, the user purchases a central air conditioner of a fluorine machine at home, and the temperature controller 100 can directly replace the control panel originally carried by the central air conditioner of the fluorine machine through the scheme of the embodiment, and networking capability is provided for the central air conditioner of the fluorine machine.

Furthermore, the innovative design of the temperature controller control method provided by the embodiment not only endows the temperature controller with unprecedented strong compatibility and flexibility, but also realizes the dynamic change of the built-in data conversion standard of the auxiliary control module 3151 on the control of the protocol type heating and ventilation equipment, thereby achieving accurate 'adaptation as required', providing wider selection for users and meeting different use requirements.

Further, the data conversion standard currently set by the auxiliary control module 3151 is set after a selection is made among a plurality of preset data conversion standards, and each data conversion standard corresponds to a specific first type heating ventilation device 501. Specifically, a plurality of optional data conversion standards are preconfigured, each data conversion standard corresponds to a certain provider or a first type of heating ventilation device 501 under a subdivision category (brand and/or model) of the provider, specifically, the specific content of the data conversion standard of the device can be obtained through a mode of negotiating with the provider, and then the data conversion standard is configured as an optional data conversion standard, so that the device of the provider is supported. The preconfiguration may be understood as a plurality of data conversion standards stored in the cloud or the auxiliary control module 3151 in advance, and selecting among a plurality of preset data conversion standards may be understood as selecting locally at the temperature controller or selecting through the terminal.

Furthermore, the user can select a matched data conversion standard for the auxiliary control module 3151 according to the first type of heating and ventilation equipment actually connected with the temperature controller 100, so that the dynamic adjustment of the specific model of the protocol type heating and ventilation equipment supported by the temperature controller 100 is realized, the temperature controller has high configurability and dynamic adaptability, and the diversified requirements of the user can be better met.

One possible way of setting the data conversion criteria is given below:

the auxiliary control module 3151 receives a specific configuration command, adjusts the data conversion standard stored therein according to the configuration command, and after the configuration is completed, the auxiliary control module 3151 performs format conversion on the control signal according to the set data conversion standard during normal operation.

The configuration command is generated in two modes, wherein the first mode is generated after a user makes a selection among a plurality of preset data conversion standards, and the second mode is automatically downloaded through the cloud according to the identified equipment brand and/or model after the auxiliary control module 3151 is successfully connected with the first type heating and ventilation equipment 501.

When the configuration command is generated by the first mode, the control method further includes establishing communication between the auxiliary control module 3151 and a terminal 200, receiving a configuration command sent by the terminal 200 by the auxiliary control module 3151, setting a data conversion standard based on the configuration command, generating the configuration command after a plurality of selectable setting items displayed on the terminal 200 are selected by a user, and each setting item represents a selectable data conversion standard.

The configuration instruction may be directly sent to the auxiliary control module 3151, or may be indirectly sent, for example, through a cloud, a gateway, or may be sent to the main control module 135 first, and then sent to the auxiliary control module 3151 by the main control module.

Setting the data conversion criteria based on the configuration instructions may be understood as setting/resetting the preset data conversion criteria to data conversion criteria matching the target setting items selected by the user on the terminal according to the instructions of the configuration instructions. For example, corresponding data conversion criteria are specified as set data conversion criteria among a plurality of data conversion criteria stored locally according to the configuration instruction. For example, the corresponding data conversion standard is downloaded according to the designated address of the cloud end of the configuration instruction, so that a large amount of data is not required to be stored locally, hardware is not required to be changed, and the product has stronger expandability.

In some examples, the user can specify the required data conversion criteria for the secondary control module 3151 via the host computer software. Specifically, when the configuration command is generated by the first case, the auxiliary control module 3151 establishes a connection with the host software of the mobile phone, where the host software may be, for example, an application program (APP) or a WeChat applet, a Payment applet, or the like, so that the user may select, through an interactive interface of the host software, among a plurality of selectable setting items, to generate the configuration command. Each selectable setting characterizes a selectable data criterion, wherein the selectable setting may be presented in the interactive interface in a number of ways, such as directly revealing a version number of the data conversion criterion, based on which the user is able to identify and select the desired data conversion criterion. Also for example, a plurality of brands and/or models of the heating and ventilation devices 500 are presented, and the user makes a selection among the plurality of heating and ventilation devices 500 presented based on the heating and ventilation devices 500 to which the thermostat 100 is actually connected.

Further, in the example, the auxiliary control module 3151 performs wireless communication by using a bluetooth technology, and the upper computer software selects a WeChat applet as an operation platform, and the user searches for and connects with bluetooth of the auxiliary control module 3151 through the applet, so as to implement direct wireless communication between the two.

In a possible application scenario, a user wants to control a central air conditioner of a fluorine machine, and the central air conditioner of the fluorine machine adopts a Modbus protocol format (i.e. a data conversion standard), so that the user can search and connect bluetooth of the auxiliary control module 3151 through a WeChat applet, and further select the Modbus protocol format for the auxiliary control module 3151 on an interface provided by the applet. In actual use, a user inputs a desired temperature set value on a control interface of the temperature controller 100 to generate the first type of command, the main control module 135 of the temperature controller 100 sends a control signal corresponding to the command to the auxiliary control module 3151, and the auxiliary control module 3151 converts the signal into a Modbus communication protocol format which can be identified by the air conditioner and sends the Modbus communication protocol format to the air conditioner unit in a wired or wireless mode to enable the air conditioner unit to work correspondingly according to the command.

In addition, the temperature controller 100 has a main control module 135, and the main control module 135 has a wireless communication function and can be remotely connected with the intelligent terminal 200 of the user.

The control method further includes operating the wireless communication function of the main control module 135 and the communication function of the supplementary control module 3151 independently of each other. Based on the establishment of the direct communication relationship between the terminal 200 and the auxiliary control module 3151, the user can directly send a control command to the auxiliary control module 3151 by using an interface provided by the upper computer software to control the first type heating and ventilation device 501 connected with the auxiliary control module 3151, and the control path does not pass through the main control module 135, so as to ensure that the user can still control the first type heating and ventilation device 501 through the communication path with the auxiliary control module 3151 even if the wireless communication of the main control module 135 is not feasible.

Further, the output on-off module 32 includes a first relay assembly and a second relay assembly.

When a second type of command is received, the output on-off module 32 is regulated to control a second type of heating and ventilation equipment 502 connected with the second type of heating and ventilation equipment, and the second type of heating and ventilation equipment specifically comprises a valve for regulating and controlling a fan coil type central air conditioner and/or floor heating in the second type of heating and ventilation equipment 502 by regulating and controlling a first relay assembly, and/or a fan for regulating and controlling a valve type fresh air system in the second type of heating and ventilation equipment 502 by regulating and controlling a second relay assembly.

Wherein the first relay assembly may include one or more relays, and likewise, the second relay assembly may include one or more relays, and the relay type may be different depending on the type of heating and ventilation device 502 being controlled. For example, the relays controlling the high, medium, and low gears of the fresh air system may be single pole single throw relays, while the relay controlling the floor heating or fan coil may be single pole double throw relays. The details of how each relay assembly controls the valve or fan of the second type of hvac device 502 will be described in the following product embodiments of the present utility model, and will not be described in detail here.

Furthermore, according to this embodiment of the present utility model, the output on-off module 32 of the temperature controller 100 includes two sets of relay assemblies, the first set is used for controlling the fan coil type central air conditioner and the valves for water floor heating, the second set is used for controlling the fan of the fresh air system, and when the second type command is received, the temperature controller 100 can respectively regulate the two sets of relays, so as to realize accurate control of the second type heating and ventilation devices 502 of different types.

The type of the heating and ventilation equipment controlled by the existing temperature controller is fixed, namely the type of the heating and ventilation equipment is determined and not changed when the equipment leaves the factory, which is unfavorable for adapting to different types of heating and ventilation equipment under various use scenes, and results in poor product universality and application scene flexibility.

In addition, in the existing temperature controller control method or temperature controller, the type of heating and ventilation equipment controlled by the temperature controller is preset when leaving a factory, and cannot be adjusted according to subsequent changes, so that obvious limitation is formed in the face of diversified use scenes, and the temperature controller is particularly prominent when different environments need to be matched with different types of heating and ventilation equipment. Because of the fixity, the product is difficult to meet the wide application demands, the general performance and the flexibility in adapting to complex scenes are greatly reduced, and the satisfaction and the use convenience of users in different occasions are reduced. Based on the above, an embodiment of the present utility model provides a temperature controller control method, which gives the temperature controller the ability to change the type of the controlled heating and ventilation device at any time.

Specifically, in the control method of the temperature controller, before receiving the control command, the control method further comprises S10-S30. Wherein:

S10, receiving a selection of the type of the heating ventilation equipment 500 by a user. The selection may be, for example, a visual selection process local to the thermostat 100, where the user interface of the thermostat 100 provides a selection option for the type of heating and ventilation device 500, and the local visual selection process may avoid a wrong selection by a user to some extent, resulting in that the type of heating and ventilation device actually connected to the thermostat is inconsistent and cannot be controlled. In some examples, as shown in fig. 4, alternative heating and ventilation device 500 types include, but are not limited to, air conditioning, floor heating and fresh air, wherein the air conditioning is subdivided into a fluorine machine (protocol type fluorine machine central air conditioner), a valve type (fan coil type central air conditioner), the floor heating has a valve type floor heating, and the fresh air is valve type (valve type fresh air system), 485 (protocol type fresh air system). On this basis, in this embodiment, all the valve type heating and ventilation devices are divided into second type heating and ventilation devices 502 (fan coil type central air conditioner, valve type floor heating, valve type fresh air system), and all the protocol type heating and ventilation devices are divided into first type heating and ventilation devices 501 (protocol type fluorine machine central air conditioner, protocol type fresh air system).

S20, generating a corresponding control interface according to the type of the selected target heating and ventilation equipment. The control interface can be switched at any time according to the actual demands of the user by means of the mode that the user autonomously selects the type of the target equipment. For example, in the using process of the temperature controller 100, input of re-selecting the type of the target heating and ventilation equipment by the user is received, and the temperature controller 100 can be dynamically switched to a corresponding control interface according to the re-selection of the user, so that the type of the target heating and ventilation equipment of the temperature controller 100 can be changed at any time according to the requirement of the user.

And S30, displaying the generated control interface, and generating the first type of command and/or the second type of command through the operation of the interface so as to realize the operation of the first type of heating and ventilation equipment 501 and/or the second type of heating and ventilation equipment 502. Specifically, the first type of command generated by the user operating on the control interface is transmitted to the auxiliary control module 3151 for execution, and the second type of command generated is transmitted to the output on-off module 32 for execution. In some examples, control interfaces may enable control such as, but not limited to, on/off, temperature setting, wind speed regulation, mode switching, etc. When the user selects a plurality of heating and ventilation device types at the same time, respectively generating independent control interfaces, namely, each control interface exclusively uses one screen.

Furthermore, the control method of the embodiment provides visual equipment selection, and according to the type of the heating and ventilation equipment selected by the user, a corresponding control interface is automatically generated, and the user can issue a control command based on the control interface, so that the universality and the adaptability of the temperature controller 100 are improved, and the dynamic change of the type of the target heating and ventilation equipment controlled by the temperature controller 100 is realized.

One possible application scenario is that a user installs a floor heating system in a living room, installs a protocol type fresh air system in a bedroom, after connecting a cable between a good-heating and protocol type fresh air system and a temperature controller, the user only needs to select two device types of fresh air (485) and floor heating (valve type) on a corresponding device type configuration interface of the temperature controller 100 to generate a corresponding control interface, then the user can switch the control interface through an interface of a sliding screen, for example, as shown in fig. 5a, the control interface can be switched to a positive screen from left sliding of a main interface, the screen displays a protocol type fresh air system (fresh air (485)) control interface, and the user generates a first type of command for controlling the protocol type fresh air system through the control of the control interface, and can start/close the fresh air system on the interface and adjust the wind speed parameter of the fresh air. The floor heating control interface is displayed on the screen, and the user can control the floor heating, turn on/off the floor heating on the interface, adjust temperature parameters of the floor heating and view temperature and humidity information. In the subsequent use, if the user needs to control other types of equipment, the corresponding heating and ventilation equipment type is reselected on the equipment type configuration interface, and the temperature controller can be restarted and the control interface is reset by clicking confirmation, so that the user can realize the change of the target heating and ventilation equipment type to be controlled by the temperature controller without other complicated setting operations.

Further, the temperature controller 100 can be remotely connected to the terminal 200 of the user through the wireless communication function of the main control module 135 (the communication function is provided by the communication module 134), so that the user can complete at least one task of network configuration, parameter setting and remote control operation of the temperature controller 100 through the APP preloaded on the terminal 200.

The control command received by the thermostat 100 may originate from a command input by the user through the thermostat 100 itself, sent by the APP to the main control module 135, and/or sent by the host software to the auxiliary control module 3151.

When the control command is derived from an instruction sent by the upper computer software to the auxiliary control module 3151, the control method further comprises the step of directly regulating and controlling the auxiliary control module 3151 to control the first type heating and ventilation equipment 501.

When the control command originates from the APP of the terminal 200, the control method further comprises receiving the control command triggered and generated by the terminal 200, and determining the control command to be a first type command and/or a second type command according to the type of the target heating and ventilation equipment.

Specifically, after the user receives the control commands triggered by the terminals 200 through the APP, the temperature controller 100 determines whether the commands belong to a first type or a second type according to the target heating and ventilation device types selected by the user, and forwards the first type of commands to the auxiliary control module 3151 for format conversion and issuing, and directly regulates and controls the execution of the output on-off module 32 for the second type of commands.

The interactive interface of APP, i.e. the corresponding interactive manner, may be shown in fig. 5b, for example, where, in the case that the user does not select any type of heating and ventilation device on the thermostat 100, the interactive interface of APP only displays the temperature and humidity value (e.g. in the (a) diagram in fig. 5b, "room temperature: 27 ℃ humidity: 43%") on the interface), and reminds the user to select the type of access device to the thermostat 100 (e.g. in the (a) diagram in fig. 5b, reminds the text "please select the type of access device on the screen of the device" on the interface). After the user selects the corresponding type of the heating and ventilation device on the temperature controller 100, the temperature controller 100 will report the data related to the selected type of the target heating and ventilation device, so that the APP updates the interactive interface to the control interface corresponding to the type of the heating and ventilation device accordingly. Furthermore, the interactive interface of the APP can be dynamically updated according to the change of the type of the target heating and ventilation equipment selected by the user, if the user selects only one heating and ventilation equipment type, the interactive interface of the APP only generates the interactive interface of the heating and ventilation equipment type, and no interactive interface of other heating and ventilation equipment types can be generated. If the user selects a plurality of heating and ventilation device types, the interactive interface of the APP can generate a plurality of heating and ventilation device types of interactive interfaces, and the user can switch among the plurality of interactive interfaces. In fig. 5b, the user selects three interactive interfaces corresponding to the types of heating and ventilation devices, and the user can switch the interactive interfaces through three options of "air conditioner", "floor heating" and "fresh air".

For example, the interactive interface of each sub-division type heating ventilation device under the air conditioner general class can be shared. Further by way of example, when the interactive interfaces of the heating and ventilation devices of each subdivision type under the air conditioning main category are shared, the user selects any subdivision type under the air conditioning main category (such as air conditioner (fluorine machine), air conditioner (valve type) or air conditioner (virtual)) at the temperature controller 100 side, and the interactive interface of the APP is shown in the (b) diagram in fig. 5b, and the interface is the shared interactive interface of the heating and ventilation devices of each subdivision type under the air conditioning main category, including status display, switch control, air conditioner temperature adjustment, air conditioner mode adjustment and air conditioner air speed adjustment. In other words, if the user selects the air conditioner (fluorine machine) in the device types, when the temperature controller 100 receives the control command for the air conditioner sent by the APP, the control command is determined to be the first type command, and then the auxiliary control module 3151 is controlled to control the protocol type fluorine machine central air conditioner. If the user selects an air conditioner (valve type) among the device types, when the temperature controller 100 receives a control command for the air conditioner sent by the APP, the control command is determined to be a second type command, and then the control output on-off module 32 controls the fan coil type central air conditioner.

Similarly, the floor heating and fresh air can be treated in this way. For example, when the interactive interfaces of the heating and ventilation devices of each subdivision type under the fresh air major category are shared, the user selects any subdivision type under the fresh air major category (such as fresh air (485), fresh air (valve type) or fresh air (virtual)) at the temperature controller 100 end, the interactive interface of the APP is shown in the (c) diagram in FIG. 5b, and the interface is the shared interactive interface of the fresh air, including status display, switch control and fresh air speed regulation of the fresh air fan. Differently, if the user selects fresh air (485) from the device types, when the temperature controller 100 receives a control command for fresh air sent by the APP, the control command is determined to be a first type command, and then the auxiliary control module 3151 is controlled to control the protocol type fresh air system. If the user selects fresh air (valve type) from the device types, when the temperature controller 100 receives a control command for the fresh air sent by the APP, the control command is determined to be a second type command, and then the output on-off module 32 is regulated to control a fan of the valve type fresh air system. The common interaction interface of the floor heating is shown in the (d) diagram in fig. 5b, and comprises state display, switch control and temperature adjustment.

In some embodiments, prior to receiving the user selection of the type of hvac device 500, the control method further includes displaying a preset main interface. The basic content of the main interface may be default or may be set by the user at his own discretion, for example, as shown in fig. 5a, where the basic content of the main interface may include background pictures, date, time, networking status, etc.

After receiving the selection of the type of the heating and ventilation equipment 500 by the user, the control method further comprises the step of generating a shortcut control corresponding to the type of the target heating and ventilation equipment 500 at the corresponding position of the main interface according to the type of the selected target heating and ventilation equipment 500, wherein the shortcut control is used for controlling the target heating and ventilation equipment 500.

The shortcut control belongs to the configurable content of the main interface and dynamically changes based on the selection of the type of the heating and ventilation equipment 500 by the user, and one shortcut control is generated for each heating and ventilation equipment type on the main interface under the condition that the user selects a plurality of heating and ventilation equipment types, so that the heating and ventilation equipment can be controlled only through the main interface under the condition that the specific control interface of the heating and ventilation equipment is not passed.

The shortcut controls are arranged at the lower position of the main interface in fig. 5a, and when a plurality of shortcut controls are arranged, the shortcut controls are arranged in sequence. In the configuration process of the temperature controller 100, two heating and ventilation equipment types, namely a floor heating (valve type) and a fresh air (485), are selected by a user, and then two shortcut controls are generated on a main interface, namely a shortcut control of the fresh air and a shortcut control of the floor heating in sequence from left to right as shown in fig. 5 a. Both shortcut controls are used for the on/off control of the device, and when a user clicks the shortcut control of the floor heating, the temperature controller 100 will control the floor heating to be started. For example, when the user clicks the shortcut control for floor heating again, the thermostat 100 will control the floor heating to be turned off.

In addition, after the shortcut control is generated, the control method further comprises the steps of controlling the target heating and ventilation equipment 500 according to a first control applied to the shortcut control, and/or jumping from the main interface to a control interface of the corresponding heating and ventilation equipment according to a second control applied to the shortcut control. At least one of the clicking times and the pressing time length between the first control and the second control is different, so that different control purposes are achieved through different controls aiming at the same shortcut control.

In some examples, the first operation is a click, and the second operation is a long press for more than 3 seconds, and if a shortcut control is clicked, the temperature controller 100 will directly control the corresponding heating and ventilation device 500, for example, turn on/off the heating and ventilation device 500. If a shortcut control is pressed for more than 3 seconds, the temperature controller 100 will directly jump from the main interface to the control interface of the heating and ventilation device 500 corresponding to the shortcut control, and further realize direct jump of the control interface of the heating and ventilation device through the second control, so that the tedious process of searching for the required control interface through screen-by-screen switching is avoided.

In addition, the current temperature control technology faces a certain limitation in application, and mainly is characterized in that the control capability of the temperature control technology is limited to directly controlling the physical heating and ventilation equipment connected with the temperature control technology in a wired mode. This means that once the heating and ventilation device is installed far from the thermostat, especially in those environments where the span is large or the wiring is inconvenient, the traditional wired connection is not only expensive to implement, but also constitutes a considerable challenge on a physical level, severely limiting the deployment flexibility and coverage of the thermostat.

Based on this, an embodiment of the present utility model further provides a temperature controller control method, which aims to give the temperature controller the ability to construct and manage virtual heating and ventilation equipment, and design a virtual control interface matched with the virtual heating and ventilation equipment. Through the bridge function of the cloud platform or the intelligent binding technology among devices, the virtual avatars can accurately correspond to and remotely regulate and control the physical heating and ventilation devices actually installed in various environments, so that virtual and real blending in the heating and ventilation device control field is skillfully realized.

Specifically, in this embodiment, before receiving the control command, the control method further includes S100 and S200. Wherein:

s100, selecting a target virtual heating and ventilation device from a plurality of virtual heating and ventilation devices, and generating a virtual control interface corresponding to the device type of the target virtual heating and ventilation device. The virtual heating and ventilation equipment is understood to be non-physical heating and ventilation equipment, the optional virtual heating and ventilation equipment is displayed in an interface of the temperature controller in the form of icons or characters, the control functions required by different equipment types are different, and further the control interfaces corresponding to the different equipment types are also different.

S200, displaying the virtual control interface, and controlling a communication module 134 to control the external device 600 which establishes a communication relationship with the temperature controller 100 according to the control accepted by the virtual control interface.

It should be noted that, since the target virtual hvac device only indicates the device type and is not associated with any entity controlled hvac device 500, in the initial state after the virtual control interface is generated, it cannot control any entity controlled hvac device 500, or, before the user does not configure the corresponding entity controlled hvac device 500 for the virtual control interface, the virtual control interface is in a free state, and a control event sent by the thermostat 100 based on a manipulation received by the virtual control interface cannot trigger any entity controlled hvac device 500.

After the virtual control interface is generated, the user needs to further configure the corresponding entity heating and ventilation device 500 for the virtual control interface, and according to different entity controlled heating and ventilation devices 500 configured by the user, the entity heating and ventilation devices 500 that can be matched and controlled by the virtual control interface are different, and further in this embodiment, the entity heating and ventilation devices 500 that can be matched and controlled by the virtual control interface are changeable. In other words, the configuration of the virtual control interface is divided into two steps, namely, generating a virtual control interface which is not used for controlling the free state of any physical hvac device 500, and further matching the free state virtual control interface with the corresponding physical hvac device 500. Wherein the selection of the device type of the virtual control interface and the selection of the entity controlled hvac device 500 that it can control are both freely defined by the user.

Furthermore, in the control method provided by the embodiment, the corresponding virtual control interface is generated according to the virtual heating and ventilation equipment selected by the user, the control interface truly simulates the main control elements and the operation modes of the entity controlled heating and ventilation equipment 500, and then the virtual and real interaction is realized by associating the virtual control interface with the control items of the entity heating and ventilation equipment 500, so that the flexibility and convenience of the control of the temperature controller 100 are greatly improved.

In one manner of selecting a target virtual hvac device from a plurality of virtual hvac devices, as shown in fig. 5c, the user-specific manipulation of the control screen 14 switches into a predetermined configuration interface in which a plurality of virtual hvac devices are displayed for selection, as shown in fig. 5c, it is seen that the air conditioning, floor heating and fresh air all correspond to the "virtual" option for the user to select the desired target virtual hvac device. After the user selects fresh air (virtual) and floor heating (virtual), the temperature controller 100 generates a corresponding virtual control interface according to the generated fresh air (virtual) and floor heating (virtual).

Further, in S200, the control communication module 134 controls the external device 600 in communication with the thermostat 100, which specifically includes sending a first event associated with a currently triggered function control action on the virtual control interface to the gateway 400 and/or the cloud 301, so that the gateway 400/the cloud 301 can determine a matched scene in the stored execution scenes, and control the external device 600 defined by the scene to execute the function.

Specifically, the first event is associated with a current action of a target function control, where the target function control is a function control currently triggered on the virtual control interface, so that the gateway 400 and/or the cloud 301 can determine a matched execution scenario among the stored execution scenarios and control an executable function of the external device 600 defined by the execution scenario to be executed, the execution scenario stored by the gateway 400 and/or the cloud 301 is predefined by a user at the terminal 200, and each execution scenario defines a mapping relationship between an action of one function control of the virtual control interface and at least one executable function of the at least one external device 600. The external device 600 may be a physical hvac device. Of course, in special use situations, the external device 600 may be other intelligent devices, such as an air purifier, a sweeping robot, etc.

During normal use, the thermostat 100 is able to trigger a corresponding executable function of the physical hvac device 500 that matches the first event sent out based on the user's manipulation on the virtual control interface that is targeted. The control method takes the gateway 400 and/or the cloud 301 as a bridge, so that the temperature controller can control a wider range of external equipment. The mapping relation between each functional control on the virtual control interface and the external device 600 is allowed to be changed at any time by a user so as to match different entity heating and ventilation devices 500, so that the matching relation between the virtual device and the entity controlled device is dynamically adjusted, that is, the entity heating and ventilation device 500 controlled by the virtual control interface can be changed and expanded according to actual requirements. For example, the user may match the various functionality controls of a virtual control interface to different control items of an entity hvac device 500, respectively, such that the entity hvac devices 500 controlled by the functionality controls of one virtual control interface are identical, but the specific executable functions of the controlled entity hvac devices 500 are different.

For example, as shown in fig. 5c, the virtual control interface corresponding to the fresh air system includes a switch control and a wind speed switching control, where the switch control is configured to control an on/off function of the fresh air system, and the wind speed switching control is configured to control the wind speed switching function of the fresh air system, so that the virtual control interface forms a remote control interface of the fresh air system. Of course, the user may also match different entity controlled hvac devices 500 for different functionality controls of a virtual control interface, so that one virtual control interface may control multiple entity controlled hvac devices 500. For example, in the virtual control interface corresponding to the fresh air system, the switch control is configured to switch the on/off function of the fresh air system, and the wind speed switching control is configured to switch the wind speed switching function of an air conditioner, so that the virtual control interface forms the remote control interfaces of the two heating and ventilation devices 500.

Furthermore, in the above embodiment, the problem that the temperature controller 100 can only control a single device or a fixed scene and cannot flexibly adjust the control range according to the user requirement is solved by the bridge function of the gateway/cloud platform. By defining the execution scene, the functional controls of the virtual control interface are associated with the executable functions of the plurality of entity heating and ventilation devices 500, so that the temperature controller 100 can control the plurality of devices and the complex scene, and the control flexibility and the control expandability are improved.

One possible use scenario of the above method is further described below, in which a user wants to control a floor heating of a living room and a protocol type fluorine central air conditioner of a bedroom through one thermostat 100, wherein the thermostat 100 is installed in the living room and is connected with a floor heating valve by a wire through an output on-off module 32, and wiring is very troublesome because the distance between the floor heating and the protocol type fluorine central air conditioner of the bedroom is too long. According to the scheme provided by the embodiment, a user can virtualize a virtual control interface of a protocol type fluorine machine central air conditioner through the temperature controller 100, add the temperature controller 100 and the protocol type fluorine machine central air conditioner to a network through the terminal 200, and further store corresponding execution scenes to a cloud after binding each functional control on the virtual control interface with each control item of the protocol type fluorine machine central air conditioner through an execution scene definition function of the terminal 200. For example, the execution scene a is defined as an on/off function item of the linkage protocol type central air conditioner of the fluorine machine when the on/off control on the virtual control interface acts, the execution scene B is defined as a mode switching function item of the linkage protocol type central air conditioner of the fluorine machine when the mode switching control on the virtual control interface acts, and the execution scene C is defined as an air speed switching function item of the linkage protocol type central air conditioner of the fluorine machine when the air speed switching control on the virtual control interface acts. In the subsequent use process, a user can directly control the living room floor heating connected with the controller through the output on-off module 32 of the controller 100, and the protocol type fluorine machine central air conditioner of the bedroom is controlled wirelessly through the virtual control interface provided by the controller 100. The specific process of controlling the protocol type fluorine central air conditioner can be that, for example, when a user clicks a switch control on a virtual control interface to an on action, the temperature controller 100 reports an on event of the switch control to the cloud 301, the cloud 301 matches the stored execution scene a based on the event, and issues a control command of opening the air conditioner to the protocol type fluorine central air conditioner based on an execution result defined by the execution scene a (namely, linkage of on/off functions of the protocol type fluorine central air conditioner), so that the working state of the protocol type fluorine central air conditioner is adjusted to be consistent with the current action of the switch control on the virtual interface. The control principle of other functional controls (mode switching controls and wind speed switching controls) on the virtual control interface is similar to the control principle. And further, through the temperature controller 100, a user can control the floor heating of the living room and the protocol type fluorine machine central air conditioner of the bedroom.

Further, in explanation, the user has a unique account number and a unique password on the corresponding application program of the terminal 200 (e.g., the mobile phone 201), and adds intelligent devices after logging in the application program based on the account number and the password, where the intelligent devices may be controlled devices (e.g., a floor sweeping robot, an intelligent window pusher, an air purifier, a heating and ventilation device, etc.), or may be control devices (e.g., the temperature controller 100, etc.). A smart device that is added to the account may be understood as a device that is added to the user that has the right to manage (e.g., delete, control function execution, configure parameters, etc.).

Wherein, the heating and ventilation equipment 500 and the temperature controller 100 with networking capability can be added into the application program of the user through the distribution network. Taking the distribution network of the temperature controller 100 as an example, the specific process of the distribution network may be as follows:

When the temperature controller 100 is not in the network distribution state, the temperature controller 100 is subjected to specified operation to enter the network distribution mode. In a specific example, the specified operation may trigger a "reset network" option displayed by the specified operation, and after detecting that the option is selected, the thermostat clears the existing network distribution information and enters the network distribution mode.

In the network configuration mode, a request network configuration message is sent outwards (the request message can be sent outwards in a broadcast form through a bluetooth communication protocol), so that the terminal 200 can scan and search the temperature controller 100 through a corresponding application program, after a user selects the temperature controller 100 to be configured with a network and inputs corresponding network configuration information, the terminal 200 sends the network configuration information to the corresponding temperature controller 100 (the network configuration information can be sent to the temperature controller 100 through a bluetooth direct connection mode), and the temperature controller 100 is connected to a network based on the network configuration information, so as to complete the network configuration. In a specific example, when the temperature controller 100 supports WIFI communication, the network configuration information may be, for example, a name and a password of an available WLAN network of the router 401, and the temperature controller 100 is connected to the network of the router 401 based on the name and the password.

After the network deployment is completed, the temperature controller 100 is added to the user, and managed by the user, and the temperature controller 100 after the network deployment has networking capability, and can communicate with the gateway 400 and/or the cloud 301 to realize remote control and configuration.

Further, in S200, the control communication module 134 controls the external device 600 that establishes a communication relationship with the temperature controller 100, and may further include sending the first event to the external device 600 according to the pairing relationship, where the first event is used to trigger the external device 600 to adjust the working state to match with the controlled function control action on the virtual control interface.

The pairing relationship may be pre-established, and the external device 600 may be a heating and ventilation device 500, or may be another intelligent device (such as an intelligent wall switch) that may establish a pairing relationship with the temperature controller 100. The thermostat 100 may establish a pairing relationship with one external device 600, or may establish a pairing relationship with a plurality of external devices 600 at the same time. After the pairing relationship is established, the temperature controller 100 sends a first event to the switch device based on the manipulation received on the virtual control interface, where the first event is used to trigger the on-off state of a control channel of the switch device to be switched to match with the action of a target functional control, where the target functional control is a functional control manipulated on the virtual control interface.

Furthermore, according to this embodiment of the present utility model, by the intelligent binding technology (pairing) between devices, the temperature controller 100 can directly implement communication mutual control with the external device 600, and the gateway 400 or the cloud 301 is not needed, so that the control efficiency is higher, and the control path is more stable.

One possible application scenario is explained in the following, in this scenario, a user needs to control a wall switch through a thermostat, and further needs to establish a pairing relationship between the thermostat 100 and a wall switch, specifically, after a certain function control (for example, more than 4 seconds) of a virtual control interface of the thermostat 100 is pressed for a long time and a key (for example, more than 4 seconds) of the wall switch is pressed for a long time, after the two enter a pairing mode, the two mutually send own identification information (for example, a MAC address for uniquely identifying a device) to the opposite party, so that after the identification information of the opposite party is stored locally, the pairing is completed. When the functional control of the virtual control interface is controlled subsequently, the temperature controller 100 will send an action event outwards, where the action event at least carries the identification information of the temperature controller 100 and the current action of the controlled functional control, after the wall switch receives the action event, the wall switch verifies that the identification information is locally stored, that is, determines that the action event is legal, and further controls the control channel of the corresponding button to switch to be consistent with the current action of the controlled functional control, for example, if the current action of the controlled functional control is on, the relay of the control channel of the control button is attracted, and if the current action of the controlled functional control is off, the relay of the control channel of the control button is disconnected, so that the temperature controller 100 controls other external devices 600 in a cross-category manner.

The present utility model also provides a thermostat 100, which thermostat 100 can be used to implement a thermostat 100 control method provided in the above embodiment. Further, as shown in fig. 6 to 16, the temperature controller 100 provided in each embodiment may be understood as hardware components and software programs required for implementing the control method of the temperature controller 100. It should be noted that, the embodiment of the present disclosure provides the temperature controller 100 with a focus on describing the hardware implementation scheme of the temperature controller 100 in detail, and further, the following contents of information interaction, execution process, implementation manner, principle, function, effect, etc. among the modules in the embodiments of the temperature controller 100, since the embodiment of the control method of the present disclosure is based on the same conception, specific contents may be referred to the description in the embodiment of the method of the present disclosure, and the description of the same features/schemes may not be repeated in the embodiment.

Specifically, as shown in fig. 6, the temperature controller 100 at least includes a main control module 135, an auxiliary control module 3151, and an output on-off module 32. The main control module 135 is disposed on the control circuit board 13, the auxiliary control module 3151 and the output on-off module 32 are directly or indirectly disposed on the power circuit board 31, and the control circuit board 13 is connected with the power circuit board 31 through pin header (131 and 311), so that the auxiliary control module 3151 and the output on-off module 32 are respectively electrically connected with the main control module 135.

The main control module 135 is configured to receive various control commands, send corresponding control signals to the auxiliary control module 3151 when a first type command is received, and regulate the output on-off module 32 to control the second type heating and ventilation device 502 when a second type command is received. The output on-off module 32 can be controlled by the main control module 135 to switch on and off states for controlling the second type of heating and ventilation device 502. The auxiliary control module 3151 is preset with a changeable data conversion standard, and is interconnected with the main control module 135 through a communication interface, and is configured to perform format conversion according to the currently set data conversion standard after receiving the control signal, so as to convert the received control signal into a data format that can be identified by the first type heating and ventilation device 501, and operate the first type heating and ventilation device 501 based on the converted data.

According to the above-mentioned aspects, the present embodiment provides a temperature controller 100, and the temperature controller 100 can control both a valve type heating and ventilation device 500 (for example, a fan coil type central air conditioner, a floor heating device, a valve type fresh air) and a protocol type heating and ventilation device 500 (for example, a protocol type fluorine air conditioner, a protocol type fresh air). The temperature controller 100 will receive a control command when in operation, and the control command may originate from a device such as the terminal 200, or may originate from the operation of the temperature controller 100 itself. The thermostat 100 controls the valve type heating and ventilation device 500 or the protocol type heating and ventilation device 500 according to the control command, if the protocol type heating and ventilation device 500 is controlled, the control command is converted into a signal in a format which can be recognized by the heating and ventilation device 500 through a protocol adaptation module integrated inside the thermostat 100 and then sent to the corresponding heating and ventilation device 500, so that the heating and ventilation device 500 can recognize the signal and execute the corresponding function.

Furthermore, the temperature controller 100 provided in this embodiment has strong compatibility and flexibility, and further realizes dynamic change of the data conversion standard built in the auxiliary control module 3151 on the control of the protocol type heating and ventilation equipment, so as to achieve accurate 'on-demand adaptation', provide wider choices for users, and meet different use requirements.

In one possible use scenario, the user's home-installed hvac 500 is a fluorine central air conditioner a, which is provided by vendor 1, and vendor 1 provides a data conversion standard to proprietary data conversion standard 1. The central air conditioner a of the fluorine machine does not have a networking function and is provided with a control panel, and a user can control the central air conditioner a through the temperature controller 100 of the embodiment. Specifically, the temperature controller 100 is first connected to the central air conditioner a of the fluorine machine in a communication manner, and then the data conversion standard in the auxiliary control module 3151 of the temperature controller 100 is preset as the private data conversion standard 1 through the terminal 200. Various controls can then be applied to the central air conditioner a of the fluorine machine through the thermostat 100 with the auxiliary control module 3151 as a medium. In this way, the temperature controller 100 provides the panel control function and the intelligent networking function for the central air conditioner A of the fluorine machine. If the fluorine central air conditioner is used for a period of time, the user finds that the prior fluorine central air conditioner A is not good, and wants to replace the prior fluorine central air conditioner B, the fluorine central air conditioner B is provided by a provider 2, and the data conversion standard provided by the provider 2 is a private data conversion standard 2. After the user changes to the central air conditioner B of the fluorine machine, the user does not need to change the temperature controller 100, and can control the central air conditioner B of the fluorine machine by only setting the data conversion standard in the auxiliary control module 3151 to be the private data conversion standard 2 after the temperature controller 100 is in communication connection with the central air conditioner B of the fluorine machine.

Further, the data conversion criteria currently set by the auxiliary control module 3151 are determined according to configuration instructions, wherein the configuration instructions are generated after a selection is made among a plurality of preset data conversion criteria, and each data conversion criterion corresponds to a specific heating and ventilation device 500.

Specifically, the auxiliary control module 3151 includes a protocol adaptation unit, and is integrated inside the thermostat 100, and serves as a bridge for connecting the protocol type heating and ventilation device. The data conversion standard in the protocol adaptation unit is changeable, and a user can match the corresponding data conversion standard for the protocol adaptation unit according to the heating and ventilation device actually connected with the temperature controller 100, so that the protocol adaptation unit can convert the received control command into a data format conforming to the stored data conversion standard.

For example, the protocol adaptation unit includes a control unit and a communication unit, where the control unit establishes a connection with the upper computer software through the communication unit, so that a user can specify a required data conversion standard among multiple preset data conversion standards through an interactive interface of the upper computer software. The communication unit adopts the Bluetooth technology to carry out wireless communication, the upper computer software selects a WeChat applet as an operation platform, and a user searches and connects Bluetooth of the auxiliary control module 3151 through the applet to realize direct wireless communication between the two.

Further, the temperature controller 100 further includes a temperature and humidity detecting unit 122 for monitoring the temperature and humidity conditions of the environment where the temperature controller 100 is located, the output on-off module 32 includes a first relay assembly and a second relay assembly, when receiving a second type command, the output on-off module 32 is controlled to control a second type heating and ventilation device 502 connected with the first type heating and ventilation device, and specifically includes controlling a fan coil type central air conditioner and/or a floor heating valve in the second type heating and ventilation device 502 by the first relay assembly according to temperature and humidity detecting data, and/or controlling a fan of a valve type fresh air system in the second type heating and ventilation device 502 by the second relay assembly.

The temperature and humidity detecting unit 122 may include a sensor for detecting temperature/humidity (e.g., a first sensor 12 referred to later) and other peripheral circuits used in cooperation therewith.

Wherein the first relay assembly may include one or more relays, and likewise, the second relay assembly may include one or more relays, and the relay type may be different depending on the type of heating and ventilation device 502 being controlled. For example, the relays controlling the high, medium, and low gears of the fresh air system may be single pole single throw relays 313, while the relay controlling the floor heating or fan coil may be single pole double throw relays 313.

In a specific example, for controlling the floor heating, the electric valve for controlling the floor heating can be used for controlling the supply of hot water, so that the aim of adjusting the temperature of the floor heating is fulfilled. For the control of valve air conditioner (fan coil type central air conditioner), the opening and closing of the electric valve can be controlled to control cold water or hot water flowing through the coil, and the fan can be controlled to blow cold air or hot air according to the set wind speed so as to regulate the temperature. The above-mentioned electric valve includes various types and different types of control modes. For example, the valve can comprise a three-wire system electric valve (for example, a three-wire two-control electric valve) which is provided with two control wires for opening and closing, and the two control wires are required to be controlled respectively during control, for example, when the valve opening wire is conducted, the electric valve is opened, and when Guan Faxian is conducted, the electric valve is closed. Further, a bi-directional motor control can be adopted, when the valve opening line is conducted with the zero line, the motor rotates left (or right), and the valve moves towards the valve opening direction. When the valve closing line is conducted with the zero line, the motor rotates right (or left), and the valve is closed. The two-wire electric valve can be divided into a normally open valve and a normally closed valve, wherein the normally open valve is in an open state when a control wire is not electrified, and the normally closed valve is in a closed state when the control wire is not electrified. The fan coil can comprise a double-pipe type fan coil and a four-pipe type fan coil, wherein in the double-pipe type fan coil, a cold/hot coil can be controlled by an electric valve to control the on/off of cold/hot water, and in the four-pipe type fan coil, a cold water coil and a hot water coil are respectively controlled by two electric valves.

Further, the temperature controller 100 further includes a screen 14 electrically connected to the main control module 135 for displaying a control interface of each heating and ventilation device 500. The main control module 135 is also configured to receive a user selection of the type of hvac device 500 prior to receiving the control command. And generates a corresponding control interface on the screen 14 according to the selected type of the target hvac device 500. And then displaying the generated control interface, and generating the first type of command and/or the second type of command through the operation of the interface so as to realize the operation of the first type of heating and ventilation equipment 501 and/or the second type of heating and ventilation equipment 502.

Specifically, the thermostat 100 has a user input module with a screen 14 that provides a user interface by which a user can select a desired type of heating and ventilation device by clicking an icon or button on the screen 14. The main control module 135 comprises a microcontroller and a corresponding control program, and according to the type of the heating and ventilation device selected by the user, the main control module 135 calls the corresponding control interface program stored in the memory to generate a control interface picture of the device, if an air conditioner (fluorine machine) is selected, the displayed control interface comprises temperature, wind speed and other functional controls for controlling the temperature regulation, wind speed switching and other functional items of the air conditioner.

Furthermore, the temperature controller of the embodiment supports the equipment selection for visualization, and automatically generates a corresponding control interface according to the type of the heating and ventilation equipment selected by the user, so that the user can issue a control command based on the control interface, thereby improving the universality and adaptability of the temperature controller 100 and realizing the dynamic change of the type of the target heating and ventilation equipment controlled by the temperature controller 100.

In addition, during the operation of the thermostat, heat generated by internal components may affect the measurement of the micro-environment temperature around the built-in humidity detection unit, thereby affecting the accuracy of the readings. In order to improve the accuracy of temperature and humidity measurement and ensure the reliability of the ambient temperature, the temperature controller of the present utility model has an innovative function designed to allow a user to automatically compensate the temperature and humidity value (i.e. manually adjust the detection data (humidity value and/or temperature value) collected by the temperature and humidity detection unit 122), so as to perform targeted correction to obtain a temperature/humidity reading closer to the actual ambient temperature/humidity. In particular implementation, the temperature controller interface is friendly to open an adjusting module, so that a user can perform fine adjustment correction within plus or minus 10 ℃ on the temperature reading originally measured by the temperature and humidity detecting unit 122 (taking 1 ℃ as step adjustment resolution). This means that the user can perform fine adjustment (for example, allow the user to perform adjustment within ±5 ℃ of the currently displayed temperature value through the temperature controller interface) on the temperature value initially measured by the temperature and humidity detection unit within ±10 ℃ according to the actual situation or the perceived environmental difference, so as to compensate the error caused by internal heating and other factors, so that the finally displayed temperature result is more accurate and is close to the actual environment state, and the adaptability and control precision of the temperature controller under different working conditions are obviously enhanced. For example, the user finds that the temperature value displayed by the temperature controller is 30 ℃ in the use process, but the actual ambient temperature is 26 ℃, at this time, the user can compensate the currently displayed temperature value by-4 ℃ through the adjusting module provided by the temperature controller, and the temperature controller subtracts 4 ℃ on the basis of the actually measured temperature value of 30 ℃ and displays the temperature value on the interface as a final temperature value. Subsequently, according to the adjusted (corrected) temperature value, the first relay assembly is controlled to control a fan coil type central air conditioner and/or a valve of a floor heating in the second type heating and ventilation equipment 502, and/or the second relay assembly is controlled to control a fan of a valve type fresh air system in the second type heating and ventilation equipment 502.

Further, the thermostat 100 further includes a proximity sensor 132 for detecting whether a user approaches the thermostat 100. The proximity sensor 132 may be, for example, a microwave radar module, an infrared sensing unit, or the like, to detect a human body.

The main control module 135 is further configured to display a preset main interface on the screen 14 before receiving the user selection of the type of the heating and ventilation device 500, and after receiving the user selection of the type of the heating and ventilation device 500, the main control module 135 is further configured to display the main interface when determining that the user approaches the temperature controller 100, where the main interface is provided with a shortcut control, where the shortcut control is a shortcut control generated according to the selected type of the target heating and ventilation device 500 and corresponding to the type of the target heating and ventilation device 500, and is used for controlling the target heating and ventilation device 500.

The shortcut control belongs to the configurable content of the main interface, and dynamically changes based on the selection of the type of the heating and ventilation device 500 by the user, and one shortcut control is generated for each heating and ventilation device type on the main interface under the condition that the user selects a plurality of heating and ventilation device types, so that the heating and ventilation device can be controlled only through the main interface under the condition that the specific control interface of the heating and ventilation device is not passed.

Further, before receiving the control command, the main control module 135 is further configured to:

And selecting a target virtual heating and ventilation device from a plurality of virtual heating and ventilation devices, and generating a virtual control interface corresponding to the device type of the target virtual heating and ventilation device. The virtual control interface is displayed, and according to the manipulation received by the virtual control interface, a communication module 134 is controlled to control the external device 600 which has established a communication relationship with the temperature controller 100. The virtual heating and ventilation equipment is understood to be non-physical heating and ventilation equipment, the optional virtual heating and ventilation equipment is displayed in an interface of the temperature controller in the form of icons or characters, the control functions required by different equipment types are different, and further the control interfaces corresponding to the different equipment types are also different.

Furthermore, the temperature controller 100 provided in this embodiment can generate a corresponding virtual control interface according to the virtual heating and ventilation device selected by the user, where the control interface truly simulates the main control elements and operation modes of the entity controlled heating and ventilation device 500, and then further associates the virtual control interface with the control items of the entity heating and ventilation device 500, so as to implement virtual and real interaction, and greatly improve the flexibility and convenience of controlling the temperature controller 100.

The main control module 135 controls the driving power supply through a MOS tube to control on/off of the power supply, so as to control the power-on time sequence (after the power-on of the core board is stabilized, the screen 14 is powered and the screen 14 is driven), thereby avoiding the abnormal operation of the whole machine caused by the problem of the power-on time sequence. In addition, the main control module 135 can also re-power up the screen 14 through the MOS transistor to reset the screen 14. The ME2212AM6G is used as the LED driving chip of the backlight.

Further, in this embodiment of the present utility model, the proximity sensor 132 uses a circuit or a combination of circuits having both human sensing and light sensing functions, such as an LTR-X1503 chip of a light bank, which communicates with the SSD201 chip of the main control module 135 using IIC.

Further, in this embodiment of the present utility model, the temperature and humidity detecting unit 122 adopts a new generation of single chip integrated temperature and humidity sensor GXHT developed by the middle-family Galaxy core, which also communicates with the SSD201 chip of the main control module 135 through the IIC.

Further, in this embodiment of the present utility model, the auxiliary control module 3151 may be understood as a circuit or combination of circuits with data storage and processing capabilities, which is capable of storing the data conversion criteria therein, and supporting the user to modify the stored data conversion criteria as desired in order to adapt to a particular heating and ventilation device 50.

In some examples, the auxiliary control module 3151 specifically includes a protocol adaptation unit and a 485 communication circuit, where the protocol adaptation unit includes a control unit and a communication unit, and a changeable data conversion standard is preset in the control unit, and the control unit establishes communication with the terminal 200 through the communication unit, so as to change the data conversion standard based on an instruction of the terminal 200. The protocol adaptation unit is communicated and interconnected with the 485 communication circuit, and the 485 communication circuit is externally provided with a 485 protocol fresh air interface for connecting with a protocol type fresh air system. The protocol adaptation unit is also directly externally provided with a bus protocol interface for connecting a protocol type fluorine machine central air conditioner.

The data conversion standard can be understood as a communication protocol for converting data. It will be appreciated that the communication protocols used by the suppliers are generally proprietary, and that the proprietary communication protocols used by the different suppliers are different, and thus the specifics of the protocols are specific to a particular hvac device 500. However, many factors, such as brand effect, equipment quality, equipment price, etc., are generally considered when the user purchases the hvac device 500, so that the suppliers, brands/models of the hvac device 500 purchased by different users may be different, in this embodiment, the auxiliary control module 3151 is integrated inside the thermostat 100, and a connection port (such as the communication terminal 316 in the following embodiments) for connecting the hvac device 500 is provided to the outside through the housing of the thermostat 100, so that the thermostat 100 of this embodiment has wider versatility.

An exemplary circuit of the auxiliary control module 3151 may be shown in fig. 11, where the protocol adaptation unit and the communication unit are integrated into a communication circuit of the line controller module MD1,485 with control and communication functions, which is built by using a MAX3485ESA chip, the line controller module may establish bluetooth direct communication with the terminal 200 to configure the data conversion standard therein, and the line controller module MD1 communicates with the SSD201 chip of the main control module 135 through serial ports (S2-TX, S2-RX), and establishes connection with the 485 communication circuit through a 485 bus to send out a signal for controlling the protocol type fresh air system through the 485 communication circuit. In addition, as shown in fig. 11, the communication circuits of the wire controller modules MD1 and 485 are together provided with an interface for connecting a first type of heating and ventilation device (the J2 interface can be understood as a communication terminal 316 in the following embodiments), for example, in fig. 11, the interfaces 1 and 2 of the J2 are used for connecting a protocol type fresh air system, and the interfaces 3 to 8 are used for connecting a protocol type central air conditioner of a fluorine machine.

Further, as shown in fig. 8, in the output on-off module 32, the first relay assembly includes one single pole double throw relay 314 (RL 4), and the second relay assembly includes three single pole single throw relays 313 (RL 1, RL2, and RL 3). The single-pole double-throw relay 314 is used for controlling a fan coil valve of a floor heating or fan coil type central air conditioner, and the three single-pole single-throw relays 313 are used for controlling high, medium and low wind speed gears of a valve type fresh air system or high, medium and low wind speed gears of the fan coil type central air conditioner. Further, in this example, as shown in a J1 port in fig. 8, when a user controls a fan coil type central air conditioner through the temperature controller 100, it is necessary to connect the single pole double throw relay 314 with a fan coil valve control port of the fan coil type central air conditioner, connect the three single pole single throw relays 313 with three gear valves of high, medium and low of the fan coil type central air conditioner respectively, and further control opening and closing of the fan coil valves by controlling the single pole double throw relay 314, so as to achieve the purpose of cooling/heating, and control switching of high, medium and low wind speeds by controlling the three single pole single throw relays 313. When a user controls the valve type fresh air system through the temperature controller 100, three single pole single throw relays 313 are required to be connected with valves of three high, middle and low gears of the valve type fresh air system respectively, so that the high, middle and low wind speeds of the fresh air system can be switched by controlling the on/off of the three single pole single throw relays 313. When a user controls the floor heating through the temperature controller 100, the single-pole double-throw relay 314 of the temperature controller 100 needs to be connected to a water pipe valve of the floor heating, and whether the floor heating is heated or not is controlled by controlling the single-pole double-throw relay 314.

Further, the main control module 135 drives each relay in the output on-off module 32 through a driving circuit. In some examples, as shown in fig. 7 and 8, in which the driving circuit uses ULN2003A darlington tube, the SSD201 chip is connected to the input end of ULN2003A through RELAY-1 to RELAY-4, and the output end of ULN2003A is electrically connected to the control end of each RELAY of the output on-off module 32, so that the SSD201 chip can drive the output on-off module 32 through ULN2003A, and uses one darlington tube to drive multiple RELAYs of the output on-off module 32, so that the space occupied by the driving circuit can be effectively reduced. The relays in the output on-off module 32 are connected to the outside through the connection terminals 312, and how to connect them is described in detail later, which is not repeated here.

In addition, in this embodiment of the present utility model, the temperature controller 100 further includes a power supply circuit, which includes a strong power supply conversion circuit (disposed on the power supply circuit board 31) and a weak power supply conversion circuit (disposed on the control circuit board 13), wherein the strong power supply conversion circuit adopts an isolated flyback switching power supply scheme, which can output 5V/1A, and satisfies the power supply output of the load and the chip on the control circuit board 13. The weak current power supply conversion circuit is used for further converting the voltage output by the strong current power supply conversion circuit into power supply voltages required by each chip, for example, a BL8039 chip of Shanghai Bei Ling is adopted to convert 5V into 3.3V, 1.8V and 1.0V, and the power supply voltages are respectively used for supplying power to the SSD201 chip, wherein 1.8V voltage is used for DDR power supply inside the SSD201 chip, and 1.0V voltage is used for supplying power to the SSD201 chip core.

Further, in this embodiment, a power-on time sequence is required between 1V and 3.3V, 1V needs to be powered on after 3.3V is powered on, and the principle of a 5V-to-1V circuit can be specifically shown in fig. 9, for example, the main control module 135 adjusts the output voltage of the 5V-to-1V circuit through a voltage adjustment port (e.g. sar_gpio 1) so as to adjust the power supply voltage of the SSD201 chip. Based on the circuit shown in fig. 9, the regulation principle of the power supply voltage of the SSD201 chip may be that, for example, when the SSD201 chip is turned on, the sar_gpio1 is pulled up to make the 5V-to-1V circuit output a voltage close to 1V (actually (49.9+75)/75×0.6v= 0.9992V), and after the start-up is completed, the sar_gpio1 is controlled to be pulled down to control the power supply voltage of the SSD201 chip to be pulled down to about 0.9V (actually (49.9+100)/100×0.6v= 0.8994V), so as to achieve the effect of reducing the power consumption.

Further, in this embodiment of the present utility model, the communication module 134 employs a circuit or combination of circuits having both WIFI and bluetooth functions. For example, the SKI.WB800DCU.1B22322 module supports WIFI and Bluetooth 5.2, adopts the SSD201 chip communication of USB and the main control module 135, and supports IEEE 802.11b/g/n/ax & BT5.2 standard from 2.4-2.5GHz. The schematic circuit diagram of the ski.wb800dcu.1b22322 module may be as shown in fig. 10, and connected with the SSD201 chip of the main control module 135 through USB1_n and USBN _p. The 3.3V power supply is adopted, and the decoupling capacitor is arranged on the USB data line, so that the radiation of the USB line can be reduced, and the interference to sensitivity is reduced. The RF is an antenna interface, the impedance is controlled according to 50Ω, and in order to conveniently adjust the radio frequency performance, a pi-shaped matching circuit is reserved between the RF port and the antenna, and the pi-shaped matching circuit is placed close to the antenna.

The working principle of the temperature controller 100 is further explained by taking a specific example:

For example, a user installs a water floor heating system and a large-gold MX air duct machine (4-core) central air conditioner at home, taking this scenario as an example, the usage principle of the temperature controller 100 may be as follows:

When the user takes the equipment of the temperature controller 100, the water floor heating system and the large-gold MX air pipe machine (4 cores) central air conditioner are connected with the temperature controller 100. The valve control line of the hydronic system is connected to the first relay assembly of the output on-off module 32, specifically to the RL4 relay port in the first relay assembly. The main MX air duct machine (4 core) central air conditioner is a protocol type fluorine machine central air conditioner, so that a wiring terminal of the main MX air duct machine (4 core) central air conditioner is connected with a wiring terminal of an auxiliary control module 3151 of the temperature controller 100, specifically, an S21 terminal of the main MX air duct machine (4 core) central air conditioner is connected with 5-8 (A1, B1, X, Y) of external J2 ports of the protocol adaptation unit. It should be explained here that the connection modes of the first type heating and ventilation device 501 and the auxiliary control module 3151 of different types may be different, and when in specific use, the user may connect according to the specific type of heating and ventilation device 500, and when the temperature controller 100 leaves the factory, a description of the connection of all the first type heating and ventilation devices 501 supported by the temperature controller may be given, so that the user can refer to the connection.

Then, the temperature controller 100 is connected with a zero fire wire, and is powered on, and under the condition that the starting of the SSD201 is initialized, the SSD201 of the main control module 135 controls the output voltage of the 5V-to-1V circuit to be reduced to about 0.9V, and the screen 14 is lightened, so that the screen 14 displays a preset main interface.

Then, the user can search the bluetooth of the auxiliary control module 3151 through the micro-letter applet of the mobile phone 201 and establish direct connection, then select the data conversion standard corresponding to the large-gold MX air duct machine (4-core) central air conditioner for the auxiliary control module 3151 on the micro-letter applet, and the auxiliary control module 3151 automatically goes to the cloud 301 to download the corresponding data conversion standard and install the data conversion standard locally for subsequent use based on the selection of the user on the micro-letter applet.

At this time, the temperature controller 100 is powered on for the first time and is not configured by the user, so that the system defaults to an optimal configuration, i.e. an optimal control scheme of the temperature controller 100, namely, an air conditioner (fluorine machine), fresh air (valve type) and floor heating (valve type), wherein the positive one screen of the temperature controller 100 is a control interface of the air conditioner (fluorine machine), the positive two screens are control interfaces of the fresh air (valve type), the positive three screens are control interfaces of the floor heating (valve type), and the main screen is provided with shortcut controls of the three heating and ventilation devices 500, as shown in fig. 12.

Thereafter, the user may enter the thermostat 100 setting interface by performing a pull-down operation from any one of the interfaces, on which a plurality of setting options are displayed, as shown in fig. 13, the "main screen setting" option may set the main screen, such as setting the content, background, layout, etc. of the main screen, the "screen 14 brightness" option may adjust the screen 14 brightness, the "system setting" option may set some settings of the thermostat 100 system, such as displaying network information, resetting the network, restarting the device, restoring the factory, etc., the "touch feedback" option may set the touch feedback of the screen 14, such as turning off/on the buzzer rattle when touched, some version information of the thermostat 100, such as software version number, MAC address, etc., the "device type" may be displayed with respect to the "local" option, and the "device type" may be used to enter the configuration interface of the heating and ventilation device 500 type.

As shown in fig. 12, the user clicks the "equipment type" option to enter the corresponding configuration interface, and reselects the type of the heating and ventilation equipment 500 on the configuration interface, and according to the heating and ventilation equipment 500 in the user's home, the user needs to select an air conditioner (fluorine machine) and a floor heating (valve type), then the corresponding main screen interface will generate a shortcut control corresponding to the air conditioner (fluorine machine) and the floor heating (valve type), the positive one screen is a control interface of the air conditioner (fluorine machine), the control interface is used for controlling the large-gold MX air pipe machine (4-core) central air conditioner, and the positive two screens are control interfaces of the floor heating (valve type), and the control interface is used for controlling the floor heating.

Thereafter, whether a person approaches (e.g., whether a person is within 30cm from the thermostat) is monitored by LTR-X1503, and the screen is turned off for standby in the case that no person is monitored for a prescribed time. After which it is monitored in real time whether someone is present and whether the screen 14 is touched.

As shown in fig. 17 to 32, the present utility model also provides a thermostat 100, and the thermostat 100 can be used to implement a thermostat control method provided in the above-mentioned embodiments. Further, for a thorough understanding of the structure and implementation thereof, reference is made to fig. 17 to 32, which illustrate the physical form of the thermostat 100, not only an implementation of the design concept, but also a physical carrier for implementing the control logic and hardware configuration of the thermostat 100. On this basis, the following embodiments are intended to disclose specific design structures and hardware details of the thermostat, and the thermostat 100 provided in these embodiments may be implemented separately, or may be combined with software and hardware logic in the foregoing embodiments to form a functional and efficient thermostat system scheme together.

Firstly, it can be understood that the temperature controller can generate a remarkable thermal effect during normal operation, which directly interferes with and affects the accurate measurement of the environmental temperature and humidity by the internal detection element, thereby affecting the credibility of temperature and humidity detection data. In addition, under different operation conditions, the heat generated by the temperature controller is not constant, but dynamically changes, which undoubtedly aggravates the difficulty of quantifying the interference of internal heat effect on temperature and humidity detection, so how to effectively inhibit the negative influence of self-heating of the temperature controller on temperature and humidity detection data becomes a technical problem to be broken.

Based on this, an embodiment of the present utility model aims to solve the problem of insufficient accuracy of the existing temperature controller in environmental temperature and humidity detection. As shown in fig. 17-27, the present utility model provides a thermostat 100 that is particularly illustrated, the thermostat 100 being adapted for wall-mounted use. Specifically, the thermostat 100 includes a panel housing 11 and a first sensor 12, wherein the first sensor 12 is disposed inside the panel housing 11 and is used for detecting temperature and/or humidity, the panel housing 11 has a first bottom wall 111 as shown in fig. 26, a distance between the first sensor 12 and the first bottom wall 111 is smaller than 5mm, ventilation holes 112 are formed through the first bottom wall 111 at positions corresponding to the first sensor 12, and when the thermostat 100 is mounted on a wall, the first bottom wall 111 is located at the bottom of the panel housing 11, and the ventilation holes 112 are opened downward. Wherein the thermostat 100 may be understood as a device capable of performing a switching action in response to a user operation or a device capable of controlling other devices to perform a switching action in response to a user operation, and in some exemplary embodiments, the thermostat 100 may be a wall switch, a thermostat, or the like. The first sensor 12 may be understood as a temperature sensor, a humidity sensor or a sensor capable of detecting both temperature and humidity.

According to the temperature controller 100 provided by the utility model, the first sensor 12 is arranged at the position, close to the bottom, of the panel shell 11, so that the position with the largest heating value is far away, and the movement route of heat can be avoided, and the influence of the heating of the temperature controller 100 on temperature and humidity detection is reduced. In addition, the ventilation holes 112 are formed in the distance of 5mm below the first sensor 12, and the ventilation holes 112 penetrate through the inner side and the outer side of the panel shell 11, so that the temperature and the humidity of the position where the first sensor 12 is located are closer to the ambient temperature and humidity, and the detection accuracy of the first sensor 12 is improved. In a preferred embodiment, the first sensor 12 is spaced 1.2mm from the first bottom wall 111.

It is noted that the downward opening of the ventilation holes 112 has the advantages that (1) the temperature and humidity below the temperature controller 100 is closer to the ambient temperature and humidity due to the physical property of upward movement of heat, the downward opening of the ventilation holes 112 can facilitate the air below to enter the ventilation holes 112, so that the temperature and humidity detection accuracy is improved, (2) the downward opening of the ventilation holes 112 can prevent dust from falling into the ventilation holes 112, and (3) the ventilation holes 112 are not blocked by the temperature controllers 100 on the left and right sides when the temperature controllers 100 are installed side by side.

The control circuit board 13 is a weak current circuit board, and is capable of receiving and processing the electrical signal of the first sensor 12 to obtain temperature and humidity data. The first sidewall 113 may be understood as a sidewall of the left or right side of the panel housing 11. In a preferred embodiment, the first sensor 12 is spaced 1.4mm from the first sidewall 113.
