When the RF circuit 11 continuously receives a radio signal including a registration mode notification command a predetermined number of times (for example, twice) (S6, S7), the control unit 10 of the load control device 101 receives the registration mode notification command for the predetermined number of times. It is determined whether or not the condition that the reception interval of the included wireless signal matches the transmission interval T1 (second period stored in the storage unit 14) is satisfied.

For example, when the predetermined number of times is set to 2, the control unit 10 determines that the time interval between the two received radio signals (radio signals including the registration mode notification command) matches the transmission interval T1 (second period). Judge whether to do.

For example, when the predetermined number of times is set to 3 times or more, when the RF circuit 11 receives the radio signal including the registration mode notification command for the predetermined number of times, the control unit 10 includes the radio signal including the registration mode notification command for the predetermined number of times. And determining whether or not the determined reception interval matches the transmission interval T1. For example, the control unit 10 sets each interval between adjacent radio signals (radio signals including the registration mode notification command) as a reception interval, and determines whether all the reception intervals coincide with the transmission interval T1 (second period). May be judged. Alternatively, the control unit 10 sets the average interval between adjacent radio signals (radio signals including the registration mode notification command) as a reception interval, and determines whether the obtained reception interval matches the transmission interval T1 (second period). May be judged.

If the RF circuit 11 continuously receives a radio signal including the registration mode notification command for a predetermined number of times and the reception interval of the radio signal including the registration mode notification command for a predetermined number of times coincides with the transmission interval T1, the control unit 10 Processing for requesting registration to the wireless adapter device 3 is performed. Specifically, the control unit 10 takes in the identification information (hereinafter referred to as “identification information ID0”) of the wireless adapter device 3 included in the wireless signal including the registration mode notification command. The control unit 10 includes a registration request command in the additional information D4, the transmission destination information D5 is the identification information ID0 of the wireless adapter device 3, and the transmission source information D6 is the identification information of the load control device 101 (hereinafter referred to as “identification information ID1”). And a transmission frame including data indicating the type of the load control apparatus 101 is created in the data D7. The transmission frame created by the control unit 10 is transmitted as a radio signal by the RF circuit 11 (S8).

When the wireless signal including the registration request command is received by the RF circuit 31, the adapter controller 30 of the wireless adapter device 3 takes in the identification information ID1 of the load control device 101 included in the wireless signal, and loads the load control device 101. Processing to register as a communication partner is performed. Specifically, the adapter control unit 30 includes a registration response command in the additional information D4, sets the transmission destination information D5 as the identification information ID1 of the load control device 101, sets the transmission source information D6 as the identification information ID0 of the wireless adapter device 3, and sets the load A transmission frame including the registration number assigned to the control device 101 in the data D7 is created. Here, for example, the registration number assigned to the load control apparatus 101 is “No. 1”. The transmission frame created by the adapter control unit 30 is transmitted as a radio signal by the RF circuit 31 (S9). Further, the adapter control unit 30 associates the identification information ID1 of the load control device 101 with the registration number “No. 1” assigned to the load control device 101 and stores it in the storage unit 34, thereby making this load control. The apparatus 101 is registered as a communication partner (S10).

(S11). Since the control unit 10 of the load control device 101 notifies the completion of the registration process by operating the notification unit 111, the user can grasp that the load control device 101 is registered in the wireless adapter device 3.

The wireless adapter device 3 includes a registration mode notification command after the registration of the load control device 101 is completed until an operation for ending the registration process is performed (until the registration switch 36 is operated again). Wireless signals are transmitted wirelessly continuously at the transmission interval T1. Therefore, each time one user registers one load control device 1, there is no need to return to the place where the wireless adapter device 3 is installed and to switch the wireless adapter device 3 to the registration mode. 1 registration work can be performed.

Subsequently, when the user operates the registration switch 16 of the load control device 102 that the user wants to register with the wireless adapter device 3 (for example, continuously operates for a predetermined time or more) (S12), the control unit 10 of the load control device 102 Switching to the registration processing mode starts processing for causing the wireless adapter device 3 to register the load control device 102.

When the RF circuit 11 continuously receives a radio signal including a registration mode notification command a predetermined number of times (for example, twice) (S13, S14), the control unit 10 of the load control apparatus 102 receives the registration mode notification command for the predetermined number of times. It is determined whether or not the reception interval of the included wireless signal matches the transmission interval T1 (second period stored in the storage unit 14).

Here, while the wireless adapter device 3 transmits the wireless signal including the registration mode notification command twice in succession (S13, S15), for example, the wireless adapter device 3 in another house has a wireless signal including the registration mode notification command. Is transmitted (S14). In this case, the reception interval T2 of the radio signals (S13, S14) including the registration mode notification command for a predetermined number of times does not match the transmission interval T1 (second period stored in the storage unit 14). At this time, the control unit 10 determines that a wireless signal including a registration mode notification command has been received from another wireless adapter device 3. And the control part 10 stops the process which requests | requires registration to the wireless adapter apparatus 3 (S16), and notifies that the registration was stopped by operating the alerting | reporting part 111. FIG.

When the user who has determined that the registration process has been stopped based on the notification content by the notification unit 111 operates the registration switch 16 of the load control device 102 again (S17), the control unit 10 of the load control device 102 causes the wireless adapter device to 3 starts again.

When the RF circuit 11 continuously receives a radio signal including a registration mode notification command a predetermined number of times (for example, twice) (S18, S19), the control unit 10 of the load control apparatus 102 receives the registration mode notification command for the predetermined number of times. It is determined whether or not the reception interval of the included wireless signal matches the transmission interval T1 (second period stored in the storage unit 14).

When the condition that the RF circuit 11 continuously receives a radio signal including the registration mode notification command a predetermined number of times and the reception interval coincides with the transmission interval T1 is established, the control unit 10 of the load control device 102 establishes a wireless adapter. Processing for requesting registration to the apparatus 3 is performed. Specifically, the control unit 10 captures the identification information ID0 of the wireless adapter device 3 included in the wireless signal including the registration mode notification command. The control unit 10 includes a registration request command in the additional information D4, the transmission destination information D5 is the identification information ID0 of the wireless adapter device 3, and the transmission source information D6 is the identification information of the load control device 102 (hereinafter referred to as “identification information ID2”). And a transmission frame including data indicating the type of the load control apparatus 102 in the data D7 is created. The transmission frame created by the control unit 10 is transmitted as a radio signal by the RF circuit 11 (S20).

In the wireless adapter device 3, when the wireless signal including the registration request command is received by the RF circuit 31, the adapter control unit 30 takes in the identification information ID 2 of the load control device 102 included in the wireless signal, and this load control device 102. Is registered as a communication partner. Specifically, the adapter control unit 30 includes a registration response command in the additional information D4, sets the transmission destination information D5 as the identification information ID2 of the load control device 102, sets the transmission source information D6 as the identification information ID0 of the wireless adapter device 3, and sets the load A transmission frame including the registration number assigned to the control device 102 in the data D7 is created. Here, for example, the registration number assigned to the load control apparatus 102 is “No. 2”. The transmission frame created by the adapter control unit 30 is transmitted as a radio signal by the RF circuit 31 (S21). Further, the adapter control unit 30 associates the identification information ID2 of the load control device 102 with the registration number “No. 2” assigned to the load control device 102 and causes the storage unit 34 to store the load control device 102 in association with the load control device 102. The device 102 is registered as a communication partner (S22).

When the RF circuit 11 receives the wireless signal including the registration response command, the control unit 10 of the load control device 102 obtains the identification information ID0 and the registration number “No. 2” of the wireless adapter device 3 from the wireless signal including the registration response command. take in. The control unit 10 of the load control device 102 completes the registration process to the wireless adapter device 3 by storing the identification information ID0 of the wireless adapter device 3 and the registration number “No. 2” in the storage unit 14 in association with each other. (S23). Since the control unit 10 of the load control device 102 notifies that the registration processing is completed by operating the notification unit 111, the user can grasp that the load control device 102 is registered in the wireless adapter device 3.

When all the load control devices 1 have been registered in the wireless adapter device 3, the user operates the registration switch 36 of the wireless adapter device 3 (for example, the registration switch 36 as a push button switch is continuously pressed for a predetermined time or more). Thus, the operation mode of the wireless adapter device 3 is switched from the registration mode to the normal mode. As described above, the load control device 1 as a communication partner can be registered in the wireless adapter device 3.

In the present embodiment, the control unit 10 of the load control device 1 is such that the RF circuit 11 continuously receives a radio signal including a registration mode notification command a predetermined number of times and includes a predetermined number of registration mode notification commands. It is determined whether or not the reception interval coincides with the transmission interval T1 (second period stored in the storage unit 14). The control unit 10 indicates that the RF circuit 11 continuously receives a radio signal including the registration mode notification command a predetermined number of times, and the reception interval of the radio signal including the registration mode notification command for a predetermined number of times coincides with the transmission interval T1. When the condition is satisfied, the wireless adapter device 3 is requested to register. Here, even if the above condition is satisfied, the control unit 10 does not match all the identification information of the transmission source (wireless adapter device 3) included in the wireless signal including the registration mode notification command for a predetermined number of times. The process of registering in the wireless adapter device 3 may not be performed (a wireless signal including a registration request command is not transmitted). Thereby, the possibility that the load control device 1 is erroneously registered in another wireless adapter device 3 can be further reduced.
