The demodulation circuit 32 is the same as the reception / demodulation circuit 21 of the receiver.

When a radio signal from the transmitter is received by the receiving antenna 31 when the system is set, the repeater 3 extracts and demodulates only the specified frequency by the receiving / demodulating circuit 32, and the data frame shown in FIG. Is supplied to. At this time, if the registration button 36 of the repeater 3 is operated to enter the registration mode, as shown in FIG. 6, the repeater 3 inserts the registration command into the command of the received data frame, The repeater identification code is inserted and relayed from the oscillation / modulation circuit 41 via the antenna 42.
Further, the repeater 3 can transmit the data frame shown in FIG. 5 by operating the registration transmission button 38 when the system is set. In this case, the repeater identification code of the repeater 3 is inserted in the identification code in the data frame.

Next, the procedure for installing and registering the equipment, which is the main feature of the present invention, will be described. The microcomputer 23 of the receiver 2 enters the registration mode when the registration button 25 is operated,
EE by extracting the identification code from the received data frame
It is programmed to be stored in PROM 24.
Further, when the erase button 26 is operated, the erase mode is entered, the identification code in the received data frame is taken out, and the EEPRO
It is programmed to match the identification code stored in M24 and erase the match. Since the receiver 2 is difficult to operate if it is installed on the ceiling or inside the wall surface, commercial power is supplied to the receiver 2 and the repeater 3 before installation, and the registration button 25 of the receiver 2 is operated to receive. After the relay 2 is set to the registration mode, the registration transmission button 38 of the relay 3 is operated to transmit the data frame of the format shown in FIG. 5, and the relay identification code of the local station of the relay 3 is transmitted to the receiver 2. register. At this time, if the repeater identification code of the repeater 3 is erroneously registered or if the repeater 3 is replaced, the delete button 26 of the receiver 2 is operated to put the receiver 2 in the delete mode, and similarly registered. The relay identifying code is erased from the EEPROM 24. After that, the receiver 2 is installed at a predetermined position.

Further, the microcomputer 33 of the repeater 3 enters the registration mode when the registration button 36 is operated, inserts the load switching command into the command of the data frame shown in FIG. 5, and transmits it to the receiver 2. Is programmed. When the microcomputer 23 of the receiver 2 receives the load switching command,
First, the lighting device 4a is programmed to be turned on and turned on. After that, the microcomputer 23 of the receiver 2
Each time the registration button 36 is operated again and a load switching command is received, the lighting fixture 4b, the lighting fixture 4c, and the lighting fixture 4 are sequentially displayed.
It is designed to be turned on by switching to d. Here, when the push button switch with lock 11 of the transmitter which is desired to be remotely controlled with respect to the lit lighting device is operated, the repeater 3 which has received the data frame from this transmitter is registered in the command of the data frame. While inserting the command,
It inserts the repeater identification code of its own station and performs relay transmission. The receiver 2 then receives the data frame from the repeater 3 (FIG. 6).
Is received, the repeater identification code previously registered in the EEPROM 24 before installation is collated with the repeater identification code in the received data frame, and if they match, the data frame of the registered repeater is judged and accepted. At this time, the load number corresponding to the lighting fixture that is turned on and the transmitter identification code in the received data frame are combined and registered in the EEPROM 24 of the receiver 2 in the format of the registration table in FIG. 7.

When the delete button 37 is operated, the microcomputer 33 of the repeater 3 enters the delete mode. Every time the delete button 37 is operated, the command of the data frame shown in FIG. It is programmed to insert and send load switch commands. Then, the transmitter that wants to release the remote control of the lit lighting device transmits a data frame, and the repeater 3 that receives this data frame inserts an erase command into the command of the data frame and A repeater identification code is inserted for relay transmission. Then, when the receiver 2 receives the data frame (FIG. 6) from the repeater 3, the EEPR is previously set.
Judge whether it is the repeater identification code registered in the OM24,
If it is a registered repeater, the transmitter identification number stored in the registration table in combination with the load number in the ON state is deleted from the EEPROM 24.

As described above, in this radio remote control system, the repeater identification code of the repeater 3 is registered in the receiver 2 before the receiver 2 is installed, and the repeater 3 in the registration mode receives the registration command. It inserts the repeater identification code of its own station and relays the data frame of the transmitter. Then, the receiver 2 that stores the repeater identification number of the repeater 3 in advance receives the data frame from the repeater 3, and identifies the transmitter identification code in the data frame and the lighting device that is currently lit. It is associated and stored in the registration table. Therefore, the receiver 2
Even after being embedded in the ceiling or on the wall surface, the transmitter can be registered in the system by operating the registration button 36 of the repeater 3. Also, the repeater 3 is necessary only when setting up the system, and does not need to be installed at all times.
A simple and inexpensive system can be built.

Further, in this radio remote control system, the repeater 3 responds to all the commands of the data frame of FIG. 5 by operating the registration button 36 of the repeater 3 to enter the registration mode and then operating the all-lighting button 39. A lighting command can be inserted and transmitted to the receiver 2. After this, the receiver 2 receiving the data frame shown in FIG. 6 is programmed to store the transmitter identification code of the transmitter in the received data frame as the all-on switch in the EEPROM 24. Then, when the transmitter identification code assigned to all the lighting switches is received, all the connected lighting fixtures 4a to 4d are turned on. Also, when the registration button 36 of the repeater 3 is operated and the all-off button 40 is operated, similarly, the all-off command is inserted and transmitted in the data frame of FIG. 5, and the data frame shown in FIG. 6 is displayed in this state. The received receiver 2 assigns the transmitter identification code of the transmitter in the received data frame as an all-off switch and EE
It is stored in the PROM 24. Thus, when the transmitter identification code of the received data frame is assigned to the all-on switch or all-off switch, the receiver 2 turns on or off all the relays 27a to 27d regardless of the load number. .

Therefore, this radio remote control system is
When the push button switch with lock 11 of the transmitter registered in the receiver 2 as the all-on switch is operated, all the lighting fixtures 4a to 4d connected to the receiver 2 are turned on, and the transmitter registered as the all-off switch is turned on. Pushbutton switch with lock 11
Is operated, all lighting fixtures 4a connected to the receiver 2
~ 4d is turned off. In a system including a plurality of receivers 2, if the transmitter identification code of a specific transmitter is registered as a lighting switch for all of these receivers, all of the lighting fixtures connected to all the receivers are registered. It becomes possible to control.
