Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

The accused devices, such as smart TVs, have gradually replaced traditional TV devices, and are becoming more and more popular in modern homes. With the development of technology and the increase of user needs, smart TVs have more and more functions. Not only can they watch different video content online, but they can also be used as a carrier to realize remote control of other smart home devices in the home.

In the related art, in the process of remotely controlling the display content of the smart TV, the content options in the interface are generally selected for display through the four direction keys of the remote control (such as an infrared remote control). However, when the size of the TV screen is large and there are many options for displaying content on the interface, multiple button operations are required to remotely display the required video content, and the remote control method is extremely cumbersome and time-consuming.

In order to solve the cumbersome problem of remote control of the controlled device, the controlled device can be remotely controlled based on ultra-wideband UWB technology. However, in the process of utilizing UWB technology, there is still a lack of a calibration method between the UWB controlled device and the UWB remote control, that is, there is a lack of a method for accurately knowing the positional relationship between the UWB controlled device and the UWB remote control, thereby affecting the accuracy of the remote control. .

In an embodiment of the present disclosure, a device calibration method is proposed, which is applied to a controlled device, and the controlled device includes a UWB antenna assembly. The method includes: establishing a connection with a remote control device, wherein the remote control device includes a UWB module. Controlling the display interface to display the location identifier, where the location identifier is used to represent the location where the UWB antenna assembly is set. According to the signal sending and receiving parameters of the UWB antenna assembly, the relative orientation of the location marker and the remote control device is determined. Using the method of the present disclosure, the display interface of the controlled device is used to display the position of the UWB antenna assembly, and further combined with the signals sent and received by the UWB antenna assembly, the relative orientation between the location mark and the remote control device is conveniently determined. Thus, the calibration of the controlled device and the remote control device is realized, ensuring that the controlled device accurately controls the displayed content under the control of the remote control device.

In some exemplary embodiments, the device calibration method of this embodiment is applied to a controlled device, such as an audio-visual display device such as a smart TV, a smart phone, a tablet computer, and a smart interactive platform. Among them, the controlled device includes a UWB antenna component, which has strong directivity and can be used as a positioning antenna. In this embodiment, the UWB antenna component may be an internal antenna structure of the controlled device itself, or an antenna structure externally connected to the controlled device.

As shown in Figure 1, the method of this embodiment may specifically include the following steps:

S110. Establish a connection with the remote control device.

S120, controlling to display the location identifier on the display interface.

S130. Determine the relative orientation of the location marker and the remote control device according to the signal sending and receiving parameters of the UWB antenna assembly.

Wherein, the controlled device also includes a control chip and a display screen, and the control chip is communicated with the display screen and the UWB antenna assembly respectively. The control chip can obtain the sending and receiving signals of the UWB antenna component, and can also control the display screen to display different content.

In step S110, the connection between the controlled device and the remote control device may be, for example, a Bluetooth connection or a WiFi connection. The remote control device includes a UWB module, so that the remote control device can remotely control the controlled device based on UWB technology.

In step S120, the location mark is used to represent the location where the UWB antenna assembly is installed. For example, if the location mark is at the top of the display interface, it indicates that the UWB antenna assembly is set on the top of the controlled device.

The location identifier can be, for example, an icon identifier or a text identifier. As shown in FIG. 8 , a location mark is displayed on the display interface to visually prompt the user where the UWB antenna assembly is located.

In step S130, in combination with the position mark displayed in step S120, the user can point the remote control device at the position mark. The UWB antenna assembly of the controlled device and the UWB module of the remote control device can identify each other, and the UWB antenna assembly can perform signal transmission and reception. According to the signal sent by the UWB antenna assembly and the received feedback signal from the UWB module, the controlled device determines the relative orientation or relative position of the location mark and the remote control device, so that the controlled device displays the information that matches the position of the remote control device on the display interface. cursor.

It can be understood that, based on the same principle, the remote control device can also know the location of the UWB antenna assembly.

In this embodiment, after the controlled device and the remote control device are paired and connected, based on UWB technology combined with the interface display of the controlled device, the mutual positioning of the controlled device and the remote control device is realized, thereby realizing the calibration of the controlled device and the remote control device. After the calibration is completed, the controlled device displays a cursor on the display interface that can be controlled by the remote control device, and the remote control device can accurately control the movement of the cursor to select the desired display content. Based on the calibration method of this embodiment, the remote control device is more convenient and accurate in controlling the display of the controlled device.

In an exemplary embodiment, as shown in FIG. 2, step S110 may specifically include the following steps:

S1101. Receive request data sent by the remote control device.

S1102. Establish a connection with the remote control device in response to the request data meeting a preset condition.

Wherein, in this embodiment, description is made by taking the connection between the controlled device and the remote control device based on Bluetooth as an example.

In step S1101, after the controlled device is turned on and the Bluetooth function is turned on, the Bluetooth antenna of the controlled device searches for nearby connectable Bluetooth devices. In the waiting state, the bluetooth function of the remote control device is turned on, and the request data can be sent. The request data may be, for example, a broadcast data packet, and the request data includes identification information of the remote control device.

The Bluetooth antenna of the controlled device can receive the request data, and can obtain the identification information in the request data.

In step S1102, the preset condition may include, for example: the request data contains a preset identifier of the remote control device, or, for example, the preset condition may include: the request data includes a preset identifier, and the signal strength of the data signal of the request data (RSSI) reaches the threshold threshold. Wherein, the preset identifier is used to indicate that the requested data belongs to the remote control device, and the preset identifier of the remote control device may satisfy: the software code is 0, for example.

In some examples, when the controlled device judges that the request data meets the preset conditions, for example: the controlled device determines that the software code in the requested data is 0, the controlled device can adapt and connect with the remote control device that sent the requested data to complete the pairing or bound.

In other examples, when the controlled device judges that the requested data meets the preset conditions, for example: the controlled device determines that the software code in the requested data is 0, and the controlled device judges that the received data signal reaches the threshold, the controlled device can communicate with The remote control device that sends the request data adapts the connection to complete the pairing or binding.

In an exemplary embodiment, the UWB antenna assembly in this embodiment includes multiple UWB antennas. Wherein, multiple UWB antennas may be arranged along the width direction of the controlled device, as shown in FIG. 8 . Alternatively, multiple UWB antennas are arranged along the length direction of the controlled device. Alternatively, multiple UWB antennas are respectively arranged at four corners of the controlled device.

In this embodiment, step S120 specifically includes the following steps:

S1201. Control to display multiple location identifiers on a display interface, and the multiple location identifiers are in one-to-one correspondence with the locations set on the controlled device by the multiple UWB antennas.

In this step, the location identifiers are in one-to-one correspondence with the UWB antennas, and each location identifier is used to indicate the location of the corresponding UWB antenna. Multiple location identifiers can use the same icon identifier to play an indicating role; or, multiple location identifiers can use icon identifiers of different colors to distinguish and display the positions of different antennas; or, multiple location identifiers can be identified by text numbers, as shown in Figure 8 Show.

In an exemplary embodiment, as shown in FIG. 3, in this embodiment, step S130 specifically includes the following steps:

S1301. In response to recognizing the pointing of the remote control device, determine a location identifier corresponding to the pointing of the remote control device.

S1302. Control the preset antenna represented by the location identifier to send a communication signal.

S1303. According to the communication signal and the feedback signal sent by the remote control device received based on the communication signal, determine the relative orientation of the location identifier and the remote control device.

Wherein, in this embodiment, multiple UWB antennas may be included, and calibration may be implemented according to any one of the antennas. Wherein, the display interface of the controlled device may display multiple location identifiers. In step S1301, after multiple position marks are displayed on the display interface of the controlled device, the user can align the remote control device with any position mark, at this time, the UWB antenna corresponding to the position mark and the remote control device can recognize each other, and the remote control device can be determined Which location identifier is specifically aligned.

In step S1302, after the remote control device aligns with the position mark, that is, aligns with the preset antenna corresponding to the position mark, the control chip controls the preset antenna to send a pulse communication signal.

In step S1303, the UWB module of the remote control device sends a pulse feedback signal after receiving the pulse communication signal sent by the preset antenna, and the preset antenna receives the feedback signal.

In this step, the preset antenna of the controlled device calculates the relative orientation between the preset antenna and the remote control device, that is, the relative orientation between the location identifier in the controlled device and the remote control device, and uploads the control chip . Alternatively, the control chip of the controlled device acquires: the time when the signal is sent out by the preset antenna and the time when the signal is received, and the control chip determines the relative orientation between the location marker and the remote control device.

The relative orientation includes the distance and/or angle of the remote control device relative to the location marker. The distance between the remote control device and the location mark and the two-dimensional coordinates of the position mark relative to the origin of the remote control device can be determined according to the time when the preset antenna sends out and receives the signal. Therefore, the included angle of the position mark on the horizontal axis can also be known according to the two-dimensional coordinates or the distance.

In an exemplary embodiment, when the UWB antenna assembly includes multiple UWB antennas. As shown in FIG. 4, step S130 may specifically include the following steps:

S1305. In response to the successively identified directions of the remote control device based on the multiple UWB antennas, determine the relative orientation of the location identifier corresponding to each UWB antenna and the remote control device according to the signal sending and receiving parameters of each UWB antenna.

S1306. Determine the orientation information of the UWB antenna assembly and the remote control device according to the relative orientations of the plurality of location identifiers and the remote control device.

Wherein, in this embodiment, the UWB antenna component may include multiple UWB antennas, and the display interface of the controlled device may display multiple location identifiers. Each UWB antenna can be calibrated separately, and the positioning information can be comprehensively inspected according to the calibration results of multiple antennas.

In step S1305, after multiple position marks are displayed on the display interface of the controlled device, the user can first align the remote control device with any position mark, and determine the position mark in conjunction with step S1301 according to the signal transceiving parameters of the antenna represented by the position mark The relative bearing to the remote control device. Then the user aligns the remote control device with any one of the remaining position marks, and then determines a relative orientation until the relative orientations of all position marks and the remote control device are determined.

In step S1306, after determining the relative orientations of all position identifiers and the remote control device, multiple relative orientations are obtained. For example, the relative orientation is the distance. According to the distance between each antenna in the UWB antenna assembly and the remote control device, the average of multiple distances can be used as the overall distance between the UWB antenna assembly and the remote control device, that is, the distance between the controlled device and the remote control device. In this way, the positioning of the controlled device and the remote control device is more precise.

In addition, in this step, when the distance between each position marker and the remote control device is determined, and the two-dimensional coordinates of each position marker relative to the origin of the remote control device, the angle between any two position markers relative to the remote control device can also be determined .

In this embodiment, after the location information of each UWB antenna and the remote control device are determined, the controlled device may display a prompt message that the calibration is completed on the display interface.

In an exemplary embodiment, as shown in FIG. 5 , after determining the relative orientation of the location identifier and the remote control device, the method of this embodiment further includes the following steps:

S140. Display a control cursor on the display interface.

S150. Identify the movement track of the remote control device according to the relative orientation.

S160. Control the cursor to move synchronously along the movement trajectory according to the movement trajectory.

S170. Determine the control in the display interface corresponding to the movement end position as the control object.

S180. Control the control object to execute the control instruction of the remote control device.

Wherein, this embodiment can be used to control the controlled device with the remote control device after the controlled device and the remote control device are calibrated with each other.

In step S140, the control cursor is a control on the display interface, and the display of the controlled device can be controlled by controlling the control cursor.

In step S150, after the remote control device and the controlled device are mutually calibrated and identified, the user moves the remote control device, and the UWB antenna assembly of the controlled device can identify the movement track of the remote control device.

In step S160, the controlled device controls and controls the cursor to move synchronously with the movement of the remote control device according to the real-time identification of the movement track of the remote control device.

In step S170, when the user stops moving, the content to be adjusted is selected by default. Therefore, in this step, the content or control corresponding to the moving destination of the remote control device is taken as the target control object.

In step S180, in combination with the user's further operation instructions on the remote control device, the control object is controlled to execute corresponding control instructions. For example, if the control instruction of the remote control device is to play the control object, the controlled device plays the control object according to the control instruction.

In an exemplary embodiment, the present disclosure also proposes a device calibration method, which is applied to a remote control device, and the remote control device includes a UWB module.

The method in this embodiment may specifically include the following steps:

S210. After establishing a connection with the controlled device, determine a relative orientation to the position mark according to the position mark displayed on the controlled device and the signal sending and receiving parameters of the UWB module.

Wherein, in step S210, the controlled device includes a UWB antenna component.

In this step, as shown in FIG. 6, establishing a connection between the remote control device and the controlled device may include the following steps, for example:

S2101. The remote control device sends request data.

In this step, the remote control device may be based on the request data sent by the Bluetooth module.

In one example, when the remote control device is first used, the Bluetooth function is not turned on. The remote control device may first be initialized so that the remote control device sends request data.

For example, within a certain distance (such as 20cm), point the remote control device at the controlled device, press and hold the "home" function key and the "menu" function key in the remote control device at the same time, and then let go until you hear the beep. At this time, the remote control device is in a state that can be searched by the controlled device, and in this state, the remote control device can send request data.

In another example, the remote control device is in use, and can send request data through a set trigger condition to connect with the controlled device via Bluetooth. The trigger condition may be, for example, that a certain time interval is met, or a distance from the controlled device satisfies a certain condition.

S2102. Receive a feedback message from the controlled device based on the request data, and determine that it is in a connection state with the controlled device.

In this step, when the controlled device judges that the requested data meets the preset conditions, it can bind and connect with the remote control device, and send a corresponding feedback message to inform the remote control device that it is currently in a connected state.

When the remote control device is in the connected state, the UWB module of the remote control device can receive the pulse communication signal sent by the UWB antenna assembly of the controlled device.

Therefore, the position mark is displayed on the controlled device, and after the remote control device aligns with the position mark, according to the signal transmission and reception parameters of the UWB module in the remote control device, for example: the UWB module of the remote control device receives the pulse communication signal of the UWB antenna component and sends pulse feedback Signal. According to the sent signal and the received signal, determine the relative orientation of the remote control device and the location marker.

In an exemplary embodiment, in order to further describe the present disclosure, the interaction process in the process of calibrating the controlled device and the remote control device in the embodiment of the present disclosure is shown in FIG. 7 . The calibration process specifically includes the following steps:

S1. The remote control device sends request data.

S2. The controlled device judges whether the requested data satisfies a preset condition, and if so, establishes a connection with the remote control device.

S3. The controlled device displays the location identifier on the display interface. The location identification characterizes the location of the UWB antenna assembly.

S4. When the preset antenna of the controlled device recognizes the remote control device, control the preset antenna to send a communication signal. The preset antenna is the antenna corresponding to the location identifier pointed to by the remote control device.

S5. The UWB module of the remote control device receives the communication signal and sends a feedback signal.

S6. The preset antenna of the controlled device receives the feedback signal.

S7. According to the communication signal and the feedback signal, the controlled device determines the relative orientation of the remote control device and the corresponding position mark of the preset antenna, and realizes calibration (mutual positioning of the controlled device and the remote control device).
