For example, the switch 50 is provided with a button corresponding to each of the plurality of load devices 20, and by operating each button, the load device 20 corresponding to the button is controlled according to the function assigned to the button. Will be done. As shown in FIG. 2, the switch 50 has, for example, two buttons 51. For example, when the button 51 is assigned the on / off function of the load device 20, the on / off of the corresponding load device 20 is switched by operating the specific button 51. As described above, in the load control system 1, a plurality of load devices 20 are controlled mainly by the control device 30, so that, for example, when the button 51 is operated, the switch 50 can be operated to the button 51. The corresponding signal is transmitted to the control device 30, and the control device 30 transmits a signal for switching on / off of the corresponding load device 20 according to the received signal to the relay 40, and the load device 20 is sent to the relay 40. To switch on and off. Alternatively, the control device 30 may transmit a signal for switching on / off of the corresponding load device 20 to the wireless communication device 10 according to the received signal. As will be described later, since the wireless communication device 10 wirelessly communicates with the wireless device 21 connected to the load device 20, the load device 20 can be controlled via the wireless device 21.

For example, the switch 50 has a light emitting unit 52, and the light emitting unit 52 changes the mode of light emission according to the state of the load device 20. For example, the light emitting unit 52 is switched on and off depending on whether the load device 20 is on or off. Further, for example, the light emitting unit 52 switches the light color between when the load device 20 is on and when the load device 20 is 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 by wirelessly communicating 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 turn on and off the lighting, control the dimming rate, control the color temperature, and the like.

The wireless device 21 is connected to the load device 20 and wirelessly communicates with the wireless communication device 10. The wireless device 21 may be built in 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, for example, the load device 20 connected to the wireless device 21 in response to 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 of detecting brightness. In this case, the wireless communication device 10 is installed on the ceiling or the like around the place where the load device 20 is installed, and the brightness of the load device 20 is determined by detecting the illuminance of the floor surface or the like irradiated on the load device 20. To detect. 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.

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

The wireless communication device 10 is a computer including a processor (microprocessor), a communication circuit, a memory, and the like, and includes a wireless communication unit 11, a notification 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), or the like, and can store a program 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 executing a program stored in the memory by the processor of the wireless communication device 10. The notification unit 12 notifies by executing a program stored in the memory by the processor.

The wireless communication unit 11 is realized by a communication circuit, an antenna, or the like, and wirelessly communicates with the wireless device 21 connected to the load device 20. For communication between the wireless communication unit 11 and the wireless device 21, for example, a specific low power radio in the 920 MHz band is used. A communication channel (frequency band) used for wireless communication with the wireless device 21 is set in the wireless communication unit 11. For example, when the load control system 1 includes a plurality of wireless communication devices 10, different load devices 20 are set for each of the plurality of wireless communication devices 10 by setting different communication channels for each of the plurality of wireless communication devices 10. Can be controlled. Further, the wireless communication unit 11 may wirelessly communicate with a device other than the wireless device 21. For example, the wireless communication unit 11 may wirelessly communicate with a device such as an information terminal 60.

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

Therefore, the wireless communication device 10 includes a notification unit 12 so that the user can easily confirm 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 the information regarding the communication channel set in the wireless communication unit 11 is not particularly limited. Here, for example, the notification unit 12 includes the display unit 120, and notifies information about the communication channel set in the wireless communication unit 11 by the display 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) is set to the wireless communication unit 11 according to the mode of light emission by one or more light emitting units as a display on the display unit 120. Notify information about the communication channel. The light emitting unit is realized by, for example, an LED (Light Emitting Diode) or the like. For example, the display unit 120 includes a plurality of light emitting units (for example, light emitting units 12a to 12c). The details of the notification method using the information display unit 120 for the communication channel set in the wireless communication unit 11 will be described later.

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

The infrared communication unit 14 is realized by a communication circuit, an infrared light receiving element, or the like, and receives an infrared signal. For example, when the wireless communication device 10 receives an input of predetermined information from the outside, the notification unit 12 notifies the information regarding the communication channel set in the wireless communication unit 11. The acceptance of the input of the predetermined information includes the reception of the predetermined infrared signal by the infrared communication unit 14. That is, when the infrared communication unit 14 receives a predetermined infrared signal from an external device, the notification unit 12 notifies information about the communication channel set in the wireless communication unit 11.

Returning to the description in FIG. 1, the information terminal 60 is, for example, a mobile terminal such as a smartphone or a tablet, and communicates with the wireless communication device 10. For example, the 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 notify the information about the communication channel set in the wireless communication unit 11 to the wireless communication device 10. However, as the information terminal 60, a mobile terminal such as a smartphone or a tablet may not have an infrared communication function. Therefore, the communication IF70 is used.

The communication IF70 is a device having an infrared communication function. The information terminal 60 and the wireless communication device 10 can communicate with each other by infrared rays via the communication IF 70. The information terminal 60 and the communication IF 70 are communicably connected by, for example, BLE (Bluetooth (registered trademark) Low Energy). Further, the information terminal 60 has a USB (Universal Serial Bus) connector, and the information terminal 60 and the communication IF 70 may be communicably connected via the USB connector.

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

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

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

As described above, the wireless communication device 10 is installed, for example, on the ceiling. Although detailed description will be omitted, the wireless communication device 10 is fitted and fixed in a hole provided in the ceiling so that the bottom surface portion shown in FIG. 4B is exposed to the indoor side. Therefore, the user can visually confirm the light emitting units 12a to 12c included in the wireless communication device 10. An infrared light receiving element 14a constituting the infrared communication unit 14 is provided on the bottom surface of the wireless communication device 10, and the infrared light receiving element 14a can receive infrared rays. Further, a brightness sensor 15 is provided on the bottom surface of the wireless communication device 10, and can detect the illuminance on the floor surface.

As described above, the notification unit 12 notifies information about the communication channel set in the wireless communication unit 11 according to the mode of light emission in one or more light emitting units. For example, the information about 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. Notifying a communication channel means, for example, notifying a communication channel number, and it is assumed that 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 blinks in one or more light emitting units (for example, the light emitting unit 12a). For example, once blinking means the communication channel of number 1, blinking twice means the communication channel of number 2, and so on, the user is made to recognize the relationship between the number of blinking times and the communication channel in advance. As a result, the user can easily confirm the communication channel set in the wireless communication unit 11 by confirming the number of blinks of the light emitting unit 12a provided in the wireless communication unit 11.

If the number of communication channels set in the wireless communication unit 11 is large, the number of blinks increases, and the user may erroneously recognize the notified communication channel. Therefore, the blinking interval may be used as information for expressing the communication channel set in the wireless communication unit 11. For example, the 10-digit number of the communication channel may be represented by blinking at a long interval, and the 1-digit number of the communication channel may be represented by blinking at a short interval. For example, when the blinking with a long blinking interval is performed twice and then the blinking with a short blinking interval is performed three times, the user can recognize that the communication channel number set in the wireless communication unit 11 is 23.

Further, for example, the notification unit 12 may notify the communication channel set in the wireless communication unit 11 according to the combination of lighting of each of the plurality of light emitting units. For example, the light emitting units 12a and 12b are used as light emitting units for notifying the communication channel set in the wireless communication unit 11, and a combination of lighting of the light emitting units 12a and 12b is used. For example, it is assumed that the communication channel numbers set in the wireless communication unit 11 exist from 1 to 19. At this time, the light emitting unit 12a represents the 1 digit of the communication channel number set in the wireless communication unit 11, and the light emitting unit 12b represents the 10 digit of the communication channel number set in the wireless communication unit 11. .. For example, when the light emitting unit 12b is lit, the communication channel number set in the wireless communication unit 11 is any of 10 to 19, and the communication set in the wireless communication unit 11 according to the number of blinks of the light emitting unit 12a. The one digit of the channel number is represented. For example, when the light emitting unit 12b is lit and the light emitting unit 12a blinks three times, the user can recognize that the communication channel number set in the wireless communication unit 11 is 13. Further, for example, when the light emitting unit 12b is turned off, the communication channel number set in the wireless communication unit 11 is any one of 1 to 9, and is set in the wireless communication unit 11 according to the number of blinks of the light emitting unit 12a. The one digit of the communication channel number is represented. For example, when the light emitting unit 12b is turned off and the light emitting unit 12a blinks three times, the user can recognize that the communication channel set in the wireless communication unit 11 is 3.

As described above, the wireless communication device 10 according to the present embodiment includes a wireless communication unit 11 and a notification unit 12 that wirelessly communicate with the wireless device 21 connected to the load device 20, and the notification unit 12 Notifies information about the communication channel set in the wireless communication unit 11.
