The wireless adapter device 40 is connected to the wireless router device 4 through a LAN (Local Area Network; Local Area Network) network cable. The wireless router device 4 functions as a wireless LAN access point. The wireless router device 4 is connected to an external network (for example: the Internet) 6 via an optical fiber line, an ADSL line, a cable TV line, and the like.

The lighting control system 1 can be connected to a mobile communication terminal device 5 via a wireless router device 4 . The mobile communication terminal device 5 is an information terminal device with a wireless communication function owned by a user, such as a smart phone, a tablet computer, and the like.

In addition, when the switch device 10 is registered not in the fixed transmitter 20 but in the remote-control transmitter 30, the following procedure will be performed. The user puts the remote control transmitter 30 into the login mode ( S10 ). For example, if the login button 341 is pressed for a predetermined time (for example: 2 seconds), the remote control transmitter 30 will switch to the login mode. In addition, the configuration may be such that the login button 341 is not provided on the remote control transmitter 30 . In that case, if a specific button (or a plurality of buttons) among the plurality of operation buttons 342 is pressed for a predetermined time (for example: 2 seconds) or longer, the remote control transmitter 30 will change to the login mode. When it changes to the login mode, the login display lamp 352 lights up in red.

Then, the user opens the cover plate of the switch device 10 to be registered, and confirms that the communication mode selection switch selects the first communication mode. The switch device 10, when the cover is opened, automatically changes to the login mode (S11). The user presses and holds the login button 141 for more than a predetermined time (for example: 2 seconds) ( S12 ). Using this long press as a trigger, the control unit 12 will transmit a login start instruction from the first wireless communication unit 111 in the first communication mode. When a login start command is transmitted from the first wireless communication unit 111, the login display lamp 152 blinks.

The remote control transmitter 30 in the log-in mode is in a state where it can receive a log-in start command. Once the control unit 32 of the remote control transmitter 30 receives the login start command transmitted from the switch device 10 from the wireless communication unit 31, it will transmit a connection request command as its response. When the control unit 12 of the switch device 10 receives the connection request command, the switch device 10 and the remote control transmitter 30 will be in a connected state.

Once the switch device 10 and the remote control transmitter 30 are in a connected state, a device registration process is executed between the switch device 10 and the remote control transmitter 30 ( S13 , S14 ). Once the pairing between the switch device 10 and the remote control transmitter 30 is completed, the login display light 152 of the switch device 10 will change from a blinking state to a lighting state, and turn off the light after a predetermined time (for example: 2 seconds).

Also, there is an upper limit to the number of switch devices 10 that can be registered in the remote control transmitter 30, and when the number of registered switch devices 10 reaches the upper limit, no new switch devices 10 can be registered.

Next, the user ends the log-in mode of the remote control transmitter 30 (S15). For example, if the login button 341 or a specific button among the operation buttons 342 is pressed for a predetermined time (for example: 2 seconds), the login mode of the remote control transmitter 30 will end. Once the login mode ends, the login indicator light 352 will turn off.

Fig. 7 is a sequence diagram showing the procedure of the device registration procedure of the switchgear 10 according to the embodiment. In the embodiment, the switch device 10 does not need to have a communication mode selection switch. The difference between the procedure of the device registration procedure and the switchgear 10 of the comparative example shown in FIG. 6 will be described below.

The equipment registration procedure (S10-S15) of the fixed transmitter 20 or the remote transmitter 30 is the same as that of the comparative example. When the registration procedures ( S10 to S15 ) for the fixed transmitter 20 or the remote transmitter 30 are completed, the user puts the wireless adapter device 40 in the login mode ( S16 ). For example, if the login button 441 provided on the back of the wireless adapter device 40 is pressed and held for a predetermined time (for example: 5 seconds), the wireless adapter device 40 will change to the login mode. Once transitioned to login mode, the transport light 451 will blink in blue and the notification light 452 will blink in red.

Next, after the wireless adapter device 40 changes to the login mode, the user again presses the login button 441 for a predetermined time (for example: 2 seconds) or longer ( S18 a ). Using the long press as a trigger, the control unit 42 transmits a login start command from the wireless communication unit 41 in the second communication mode. Also, the login button for transitioning to the login mode and the login button for transmitting the login start command can also be set separately.

The switch device 10 in the log-in mode is in a state where it can receive a log-in start command. Once the control unit 12 of the switch device 10 receives the login start command transmitted from the wireless adapter device 40 from the second wireless communication unit 112, it transmits a connection request command as a response. Once the control unit 42 of the wireless adapter device 40 receives the connection request command, the switch device 10 and the wireless adapter device 40 will be in a connected state.

Also, when another switch device 10 and the wireless adapter device 40 have already been in a connected state, the request connection command transmitted from the aforementioned switch device 10 will not be received by the wireless adapter device 40. accepted. In this case, the control unit 12 of the switch device 10 waits for a predetermined time before transmitting the connection request command again. After the pairing between the other switch device 10 and the wireless adapter device 40 is completed, and the connection state between the other switch device 10 and the wireless adapter device 40 is released, the connection request transmitted from the switch device 10, Only then will it be accepted by the wireless adapter device 40.

Once the switch device 10 and the wireless adapter device 40 are in a connected state, device registration processing is executed between the switch device 10 and the wireless adapter device 40 ( S19 , S20 ). Next, the user ends the login mode of the wireless adapter device 40 ( S21 ). When the user closes the cover of the switch device 10, the login mode of the switch device 10 ends (S22).

Comparing the device registration procedure of the comparative example shown in FIG. 6 with the device registration procedure of the embodiment shown in FIG. 7, the operation of the latter is easier and less prone to operational errors. In the comparative example, the trigger signal when the first communication device (the fixed transmitter 20 and/or the remote control transmitter 30 ) and the second communication device (the wireless adapter device 40 ) are to be logged in to the switching device 10 is both is transmitted by the switching device 10 . Therefore, it is necessary to switch the communication method for transmission on the way (refer to step S17 in FIG. 6 ).

In contrast, in the embodiment, the trigger signal when the first communication device is to be registered with the switch device 10 is transmitted by the switch device 10; when the second communication device is to be registered with the switch device 10 The trigger signal is transmitted by the second communication device. Therefore, there is no need to switch the communication method for transmission on the way. When there are a plurality of switch devices 10 registered in the second communication device, the switching operation of the communication mode occurs as many times as the number of switch devices 10 . Furthermore, if the device registration of the switch device 10 is performed on the second communication device without switching the communication method, a connection error may result.

Furthermore, in the comparative example, when there are multiple switch devices 10 to be registered to the second communication device, each time a switch device 10 is to be registered to the wireless adapter device 40, the registration button 141 needs to be pressed. . Regarding this point, in the embodiment, it is enough to press the login button of the second communication device once. As mentioned above, according to this embodiment, the machine registration operation of the switchgear 10 can be simplified, making the machine registration operation of users or technicians more efficient.
