(Embodiment)
Hereinafter, the embodiment will be described with reference to FIG. 1 to FIG. 4B.

Figure 1 is a configuration diagram showing an example of a load control system 1 according to an embodiment.

The load control system 1 includes a wireless communication device 10, a load device 20, a wireless device 21, a control device 30, a relay 40, and a switch 50. FIG. 1 also illustrates an information terminal 60 and a communication IF (InterFace) 70. The information terminal 60 and the communication IF 70 may be components of the load control system 1, or may be components outside the load control system 1.

In the load control system 1, a control device 30 is centrally used to control a plurality of load devices 20. Note that a system including a wireless communication device 10 and a load device 20 is also referred to as a wireless communication system 2, and a system including a wireless communication device 10 and a control device 30 is also referred to as a control system 3.

The control device 30 operates as a parent device in the load control system 1 and is a device for controlling the load device 20. The control device 30 is connected to the wireless communication device 10, the relay 40, the switch 50, etc. by wired signal lines.

The relay 40 is a switch that switches the power supply to the multiple load devices 20 on and off. The relay 40 switches the power supply to the multiple load devices 20 on and off, for example, in response to an instruction from the control device 30. The relay 40 is connected to the load devices 20 by a power line.

The switch 50 is, for example, a wall switch, and a specific load device 20 is controlled by the user operating the switch 50. An external view of the switch 50 is shown in Figure 2.

Figure 2 is an external view showing an example of a switch according to an embodiment.

For example, the switch 50 is provided with buttons corresponding to each of the multiple load devices 20, and when each button is operated, the load device 20 corresponding to the button is controlled according to the function assigned to the button. As shown in FIG. 2, the switch 50 has, for example, two buttons 51. For example, when the function of turning on and off the load device 20 is assigned to the button 51, the corresponding load device 20 is switched on and off by operating a specific button 51. As described above, in the load control system 1, the control device 30 is the center for controlling the multiple load devices 20, so that, for example, when the button 51 is operated, a signal corresponding to the operation of the button 51 is transmitted from the switch 50 to the control device 30, and the control device 30 transmits a signal to the relay 40 for switching on and off the corresponding load device 20 according to the received signal, causing the relay 40 to switch on and off the load device 20. Alternatively, the control device 30 may transmit a signal to the wireless communication device 10 for switching on and off the corresponding load device 20 according to the received signal. As described below, the wireless communication device 10 wirelessly communicates with a wireless device 21 connected to the load device 20, and can control the load device 20 via the wireless device 21.

For example, the switch 50 has a light-emitting unit 52, and the manner in which the light is emitted by the light-emitting unit 52 changes depending on the state of the load device 20. For example, the light-emitting unit 52 switches between being on and off when the load device 20 is on and off. Also, for example, the light-emitting unit 52 changes the light color when the load device 20 is on and off.

The load device 20 is a device controlled by the control device 30. A wireless device 21 is connected to the load device 20, and the load device 20 may be controlled by the wireless communication device 10 through wireless communication between the wireless communication device 10 and the wireless device 21. The load device 20 includes, for example, a lighting device. The load device 20 is controlled by the control device 30 or the wireless communication device 10 to control the on/off of lighting, the dimming rate, or the color temperature.

The wireless device 21 is connected to the load device 20 and communicates wirelessly with the wireless communication device 10. The wireless device 21 may be built into the load device 20 or may be externally attached to the load device 20.

The wireless communication device 10 wirelessly communicates with the wireless device 21 and controls the load device 20 connected to the wireless device 21 in response to, for example, an instruction from the control device 30. When the load device 20 is a lighting device, the wireless communication device 10 may have a function for detecting brightness. In this case, the wireless communication device 10 is installed on a ceiling or the like around the location where the load device 20 is installed, and detects the brightness of the load device 20 by detecting the illuminance of a floor surface or the like that is irradiated onto the load device 20. For example, the load device 20 is dimmed and controlled by the wireless communication device 10 so that the detected brightness becomes a predetermined set value. Here, the configuration of the wireless communication device 10 will be described with reference to FIG. 3.

Figure 3 is a configuration diagram showing an example of a wireless communication device 10 according to an embodiment.

The wireless communication device 10 is a computer including a processor (microprocessor), a communication circuit, a memory, etc., and includes a wireless communication unit 11, an alarm unit 12, a wired communication unit 13, and an infrared communication unit 14. The memory is a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and can store programs executed by the processor. The wireless communication unit 11, the wired communication unit 13, and the infrared communication unit 14 transmit and receive signals (information) by the processor of the wireless communication device 10 executing the programs stored in the memory. The alarm unit 12 issues an alarm by the processor executing the programs stored in the memory.

The wireless communication unit 11 is realized by a communication circuit and an antenna, etc., and communicates wirelessly with the wireless device 21 connected to the load device 20. For example, a specific low-power radio in the 920 MHz band is used for communication between the wireless communication unit 11 and the wireless device 21. A communication channel (frequency band) used when communicating wirelessly with the wireless device 21 is set in the wireless communication unit 11. For example, if the load control system 1 includes multiple wireless communication devices 10, a different communication channel can be set for each of the multiple wireless communication devices 10, so that each of the multiple wireless communication devices 10 can control a different load device 20. The wireless communication unit 11 may also communicate wirelessly with devices other than the wireless device 21. For example, the wireless communication unit 11 may communicate wirelessly with a device such as an information terminal 60.

For example, when there is a problem with wireless communication with the wireless device 21, there is a desire to check the communication channel set in the wireless communication unit 11 (wireless communication device 10). However, it is usually difficult for a user to check the communication channel set in the wireless communication unit 11.

Therefore, the wireless communication device 10 is equipped with a notification unit 12 so that the user can easily check the communication channel set in the wireless communication unit 11.

The notification unit 12 notifies information about the communication channel set in the wireless communication unit 11. The means by which the notification unit 12 notifies information about the communication channel set in the wireless communication unit 11 is not particularly limited. For example, the notification unit 12 includes a display unit 120, and notifies information about the communication channel set in the wireless communication unit 11 by displaying on the display unit 120. For example, the display unit 120 includes one or more light-emitting units, and the notification unit 12 (display unit 120) notifies information about the communication channel set in the wireless communication unit 11 by the manner of light emission of the one or more light-emitting units as display on the display unit 120. The light-emitting units are realized, for example, by LEDs (Light Emitting Diodes) or the like. For example, the display unit 120 includes multiple light-emitting units (for example, light-emitting units 12a to 12c). Details of the method of notifying information about the communication channel set in the wireless communication unit 11 using the display unit 120 will be described later.

The wired communication unit 13 is realized by a communication circuit, a connector, etc., and communicates with the control device 30 for controlling the load device 20.

The infrared communication unit 14 is realized by a communication circuit, an infrared receiving element, etc., and receives infrared signals. For example, the notification unit 12 notifies information related to the communication channel set in the wireless communication unit 11 when the wireless communication device 10 accepts input of specified information from the outside. The acceptance of the input of the specified information includes the reception of a specified infrared signal by the infrared communication unit 14. In other words, the notification unit 12 notifies information related to the communication channel set in the wireless communication unit 11 when the infrared communication unit 14 receives a specified infrared signal from an external device.

Returning to the explanation in FIG. 1, the information terminal 60 is, for example, a mobile terminal such as a smartphone or tablet, and communicates with the wireless communication device 10. For example, a user operates the information terminal 60 to notify the wireless communication device 10 of the communication channel set in the wireless communication unit 11. At this time, infrared communication is used to transmit an instruction to the wireless communication device 10 to notify information related to the communication channel set in the wireless communication unit 11. However, the mobile terminal such as a smartphone or tablet serving as the information terminal 60 may not have an infrared communication function. Therefore, a communication IF 70 is used.

The communication IF 70 is a device having an infrared communication function. The information terminal 60 and the wireless communication device 10 can communicate with each other via the communication IF 70 via infrared. The information terminal 60 and the communication IF 70 are communicatively connected with each other via, for example, BLE (Bluetooth (registered trademark) Low Energy). The information terminal 60 may also have a USB (Universal Serial Bus) connector, and the information terminal 60 and the communication IF 70 may be communicatively connected with each other via the USB connector.

The infrared communication unit 14 of the wireless communication device 10 receives, for example, from the communication IF 70 or the information terminal 60, an infrared signal indicating an instruction to notify the wireless communication unit 11 of information related to the communication channel set therein. As a result, the notification unit 12 notifies the wireless communication unit 11 of information related to the communication channel set therein.

Next, a method of notifying information about the communication channel set in the wireless communication unit 11 using the display unit 120 will be described with reference to Figures 4A and 4B.

Figure 4A is an external perspective view showing an example of a wireless communication device 10 according to an embodiment. Figure 4B is an external bottom view showing an example of a wireless communication device 10 according to an embodiment.

As described above, the wireless communication device 10 is installed, for example, on the ceiling. Although detailed explanation is omitted, the wireless communication device 10 is fixed by fitting it into a hole provided in the ceiling so that the bottom surface portion shown in FIG. 4B is exposed to the inside of the room. This allows the user to visually check the light-emitting units 12a to 12c of the wireless communication device 10. An infrared receiving element 14a constituting the infrared communication unit 14 is provided on the bottom surface of the wireless communication device 10, and infrared rays can be received by the infrared receiving element 14a. A brightness sensor 15 is also provided on the bottom surface of the wireless communication device 10, and can detect the illuminance of the floor surface.

As described above, the notification unit 12 notifies information related to the communication channel set in the wireless communication unit 11 by the manner in which one or more light-emitting units emit light. For example, the information related to the communication channel set in the wireless communication unit 11 includes the communication channel set in the wireless communication unit 11, and the notification unit 12 notifies the communication channel set in the wireless communication unit 11. Notification of a communication channel means, for example, notifying the number of the communication channel, and different communication channel numbers correspond to each frequency band. For example, the light-emitting unit 12a is a light-emitting unit for notifying the communication channel set in the wireless communication unit 11.

For example, the notification unit 12 may notify the communication channel set in the wireless communication unit 11 based on the number of times one or more light-emitting units (e.g., light-emitting unit 12a) blink. For example, the user is made aware in advance of the relationship between the number of blinks and the communication channel, such that one blink means communication channel number 1, and two blinks means communication channel number 2. This allows the user to easily check the communication channel set in the wireless communication unit 11 by checking the number of blinks of the light-emitting unit 12a provided in the wireless communication unit 11.

When there are many communication channel numbers set in the wireless communication unit 11, the number of blinks increases, and the user may mistakenly recognize the notified communication channel. Therefore, the blinking interval may be used as information to represent the communication channel set in the wireless communication unit 11. For example, the tens digit of the communication channel number may be represented by blinking with a long interval, and the ones digit of the communication channel number may be represented by blinking with a short interval. For example, if there are two blinks with a long interval followed by three blinks with a short interval, the user can recognize that the communication channel number set in the wireless communication unit 11 is 23.

For example, the notification unit 12 may notify the communication channel set in the wireless communication unit 11 according to a combination of the lighting of the plurality of light-emitting units. For example, the light-emitting units 12a and 12b are light-emitting units for notifying the communication channel set in the wireless communication unit 11, and a combination of the lighting of the light-emitting units 12a and 12b is used. For example, assume that the communication channel numbers set in the wireless communication unit 11 range from 1 to 19. In this case, the light-emitting unit 12a represents the one digit of the number of the communication channel set in the wireless communication unit 11, and the light-emitting unit 12b represents the ten digit of the number of the communication channel set in the wireless communication unit 11. For example, when the light-emitting unit 12b is lit, the number of the communication channel set in the wireless communication unit 11 is any one of 10 to 19, and the number of times the light-emitting unit 12a blinks represents the one digit of the number of the communication channel set in the wireless communication unit 11. For example, when the light-emitting unit 12b is lit and the number of times the light-emitting unit 12a blinks is three times, the user can recognize that the number of the communication channel set in the wireless communication unit 11 is 13. Also, for example, when light-emitting unit 12b is off, the communication channel number set in wireless communication unit 11 is any one of 1 to 9, and the number of times light-emitting unit 12a blinks represents the 1's digit of the communication channel number set in wireless communication unit 11. For example, when light-emitting unit 12b is off and light-emitting unit 12a blinks three times, the user can recognize that the communication channel set in wireless communication unit 11 is 3.

As described above, the wireless communication device 10 according to this embodiment includes a wireless communication unit 11 that wirelessly communicates with a wireless device 21 connected to a load device 20, and a notification unit 12, and the notification unit 12 notifies information related to the communication channel set in the wireless communication unit 11.

In this way, the notification unit 12 notifies the user of information regarding the communication channel set in the wireless communication unit 11, allowing the user to easily check the communication channel set in the wireless communication unit 11 (wireless communication device 10).

The wireless communication device 10 may further include a wired communication unit 13 that communicates with a control device 30 for controlling the load device 20.

The notification unit 12 may also notify information about the communication channel when the wireless communication device 10 receives input of specified information from the outside.

This allows the wireless communication device 10 to notify the communication channel in response to an external instruction.

The wireless communication device 10 may further include an infrared communication unit 14, and the acceptance of the input of the specified information may include the reception of a specified infrared signal by the infrared communication unit 14.

With this, even if the user does not know the communication channel of the wireless communication device 10, the user can specify a specific wireless communication device 10 using highly directional infrared communication and be notified of information about the set communication channel.

The notification unit 12 may also include a display unit 120, and may notify information about the communication channel by displaying it on the display unit 120.

This allows the user to easily check the communication channel set in the wireless communication unit 11 by checking the display on the display unit 120 provided on the wireless communication device 10.

The display unit 120 may also include one or more light-emitting elements, and may notify information about the communication channel by the manner in which the one or more light-emitting elements emit light as a display on the display unit 120.

This allows the user to easily check the communication channel set in the wireless communication unit 11 by checking the light emission state of one or more light-emitting units provided in the wireless communication device 10.

The notification unit 12 may also notify the communication channel based on the number of times one or more light-emitting units blink.

According to this, for example, by having the user recognize in advance the relationship between the number of blinks and the communication channel, the user can easily check the communication channel set in the wireless communication unit 11 by checking the number of blinks of one or more light-emitting units provided in the wireless communication device 10.

The display unit 120 may also include multiple light-emitting elements, and the notification unit 12 may notify the communication channel according to a combination of the illumination of the multiple light-emitting elements.

According to this, for example, by having the user recognize in advance the relationship between the lighting combination and the communication channel, the user can easily check the communication channel set in the wireless communication unit 11 by checking the lighting combination of each of the multiple light-emitting elements provided in the wireless communication device 10.

The load device 20 may also include a lighting device.

This allows the user to easily check the communication channel set in the wireless communication unit 11 that is used to communicate with the lighting device.

The wireless communication system 2 according to this embodiment includes a wireless communication device 10 and a load device 20.

This makes it possible to provide a wireless communication system 2 that allows easy confirmation of the communication channel set on the wireless communication device 10.

The control system 3 according to this embodiment also includes a wireless communication device 10 and a control device 30 for controlling the load device 20.

This makes it possible to provide a control system 3 that can easily check the communication channel set in the wireless communication device 10.

The load control system 1 according to this embodiment also includes a wireless communication device 10, a load device 20, and a control device 30 for controlling the load device 20.

This makes it possible to provide a load control system 1 that can easily check the communication channel set in the wireless communication device 10.

(Other embodiments)
Although the wireless communication device 10 and the like according to the embodiment have been described above, the present invention is not limited to the above embodiment.

For example, in the above embodiment, the information on the communication channel set in the wireless communication unit 11 has been described as including the communication channel set in the wireless communication unit 11, but this is not limited thereto. For example, the information on the communication channel set in the wireless communication unit 11 may include information indicating whether the wireless communication device 10 is in a state to notify the communication channel set in the wireless communication unit 11, and the notifier 12 may notify whether the wireless communication device 10 is in a state to notify the communication channel set in the wireless communication unit 11.

When the notification unit 12 notifies that the wireless communication device 10 is in a state in which the wireless communication unit 11 is to notify the communication channel set in the wireless communication unit 11, the wireless communication unit 11 wirelessly transmits the communication channel set in the wireless communication unit 11. Transmitting a communication channel means transmitting information indicating the communication channel (e.g., the number of the communication channel). For example, the destination of the communication channel is specified by the information terminal 60. For example, when the information terminal 60 transmits an instruction to the wireless communication device 10 by infrared communication or the like to notify information regarding the communication channel set in the wireless communication unit 11 (specifically, information indicating whether the wireless communication unit 11 is in a state in which the communication channel set in the wireless communication unit 11 is to be notified), the information terminal 60 also transmits the MAC (Media Access Control) address of the destination of the communication channel by infrared communication or the like. This allows the wireless communication unit 11 to wirelessly transmit the communication channel set in the wireless communication unit 11 to the MAC address. In addition, because there is a limit to the amount of information that can be sent at one time in infrared communication, when a MAC address is sent via infrared communication, it may be sent in multiple parts.

The destination MAC address may be the address of the information terminal 60, the address of the load device 20, or the address of another device. For example, when the information terminal 60 receives a communication channel set in the wireless communication unit 11, the information terminal 60 displays the communication channel set in the wireless communication unit 11 as an image or outputs it as sound. Also, for example, when the load device 20 (e.g., a lighting device) receives a communication channel set in the wireless communication unit 11, the load device 20 notifies the communication channel set in the wireless communication unit 11 by the manner in which it emits light.

In addition, when the notification unit 12 is notifying that the wireless communication device 10 is in a state in which the communication channel set in the wireless communication unit 11 is to be notified, the wired communication unit 13 may transmit the communication channel set in the wireless communication unit 11 to the control device 30 via a wired connection. For example, the control device 30 may transmit the communication channel set in the wireless communication unit 11 to the switch 50, and the switch 50 may notify the communication channel set in the wireless communication unit 11 by the light emission mode of the light-emitting unit 52 (see FIG. 2). In addition, if the switch 50 has a display panel or the like, it may display the communication channel set in the wireless communication unit 11 on the display panel.

For example, the light emitting unit 12a of the wireless communication device 10 being lit means that the wireless communication device 10 is in a state where it is reporting the communication channel set in the wireless communication unit 11, i.e., that the wireless communication unit 11 is in a state where it is wirelessly transmitting the communication channel set in the wireless communication unit 11, or that the wired communication unit 13 is in a state where it is wiredly transmitting the communication channel set in the wireless communication unit 11 to the control device 30. Therefore, the user can recognize whether the wireless communication device 10 is in a state where it is reporting the communication channel set in the wireless communication unit 11 by checking whether the light emitting unit 12a is lit or off.

In this way, the information regarding the communication channel may include information indicating whether the wireless communication device 10 is in a state to report the communication channel.

This allows the user to easily confirm that the wireless communication device 10 is in a state where it can report the communication channel set in the wireless communication unit 11.

In addition, when the notification unit 12 notifies that the wireless communication device 10 is in a state to notify a communication channel, the wireless communication unit 11 may transmit the communication channel wirelessly.

This allows the user to confirm that the wireless communication device 10 is in a state in which it can report the communication channel set in the wireless communication unit 11, and to easily confirm the communication channel set in the wireless communication unit 11 via a device (information terminal 60, load device 20, or other device) that receives the communication channel wirelessly transmitted from the wireless communication unit 11.

In addition, when the notification unit 12 notifies that the wireless communication device 10 is in a state to notify a communication channel, the wired communication unit 13 may transmit the communication channel to the control device 30 via a wired connection.

This allows the user to confirm that the wireless communication device 10 is in a state in which it is reporting the communication channel set in the wireless communication unit 11, and to easily check the communication channel set in the wireless communication unit 11 via the control device 30, which has received the communication channel transmitted by wire from the wired communication unit 13. For example, the control device 30 transmits the communication channel set in the wireless communication unit 11 to a device (such as a switch 50) connected to the control device 30, and the user can easily check the communication channel set in the wireless communication unit 11 via that device.

In addition, for example, in the above embodiment, an example was described in which the wireless communication device 10 has three light-emitting units 12a to 12c, but the wireless communication device 10 may have one, two, or four or more light-emitting units.

In addition, for example, in the above embodiment, an example was described in which the display unit 120 is a light-emitting unit, but the display unit 120 may be a display, and the notification unit 12 may notify information about the communication channel set in the wireless communication device 10 by displaying an image or video on the display.

In addition, for example, in the above embodiment, an example was described in which the notification unit 12 was the display unit 120, but the notification unit 12 may be a buzzer or a speaker, and information regarding the communication channel set in the wireless communication unit 11 may be notified by voice using the buzzer or the speaker.

In addition, for example, in the above embodiment, the wireless communication device 10 is described as including a wired communication unit 13, but it does not have to be included.

For example, in the above embodiment, the wireless communication device 10 has been described as having an infrared communication unit 14, but this need not be the case. For example, in the above embodiment, the notification unit 12 has been described as notifying information related to the communication channel set in the wireless communication unit 11 when the infrared communication unit 14 receives a specific infrared signal from an external device, but this is not limited to the above. For example, the wireless communication device 10 may have a button for notifying information related to the communication channel set in the wireless communication unit 11, and when the button is operated, the notification unit 12 may notify information related to the communication channel set in the wireless communication unit 11.

In addition, for example, in the above embodiment, an example was described in which the load device 20 was a lighting device, but the load device 20 is not limited to a lighting device.

Furthermore, each component included in the wireless communication device 10 of the above embodiment may be realized as a dedicated or general-purpose circuit.

In addition, each component included in the wireless communication device 10 of the above embodiment may be realized as an LSI (Large Scale Integration), which is an integrated circuit (IC).

In addition, the integrated circuit is not limited to an LSI, and may be realized by a dedicated circuit or a general-purpose processor. A programmable FPGA (Field Programmable Gate Array) or a reconfigurable processor in which the connections and settings of circuit cells inside the LSI can be reconfigured may be used.

Furthermore, if an integrated circuit technology that can replace LSIs emerges due to advances in semiconductor technology or other derived technologies, it is natural that each component included in the wireless communication device 10 may be integrated into an integrated circuit using that technology.

In addition, the present invention also includes forms obtained by applying various modifications to the embodiments that a person skilled in the art may conceive, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope of the spirit of the present invention.
