In the communication of the circuit connection procedure (hereinafter referred to as the line connection procedure) according to the standard of the radio equipment for 00 MHz band data transmission, the signal of the line connection procedure (the signal transmitted from the transmitter when the call name is transmitted is referred to. .), Which is registered to the controlled station, and when operated by the control station, the line connection procedure signal and the registration calling signal and the control signals for the water heater, heating device, etc. And the controlled station receives these signals, and the wireless remote control method has the function of controlling the water heater and the heating device only when receiving the registration call signal registered in the controlled station. is there.

Description will be made with reference to the flow chart of FIG.
The control station side operated from the slave station of the wireless remote control device is called a calling station in operation. The terminal station, that is, the control station side such as the water heater and the heating device is called a called station in operation. (101) First, the calling station starts from the standby state. When remote control is desired (102), a call is made from the calling station. Then (10
3) After the transmission delay timer of the transmission time limit device (the device that does not transmit unless the transmission prohibition time has stopped for a predetermined transmission prohibition time after the radio wave is emitted and the transmission prohibition time has elapsed) , (104) is provided with carrier sense for preventing interference, and after confirming that there is no carrier, (105) sends the next signal (individual identification signal).

This signal is a 24-bit bit synchronization signal,
31 frame sync signals and 63-bit call signals. The (106) call signal includes a call name and error correction code and has the following configuration. The call signal is a62 ・ a61 ・ a
From 63 to 63 bits of a2.a1.a0. However, a62 to a0 are the coefficients of the terms from the 62nd order to the 0th order of the polynomial on the finite field whose order is 2 listed below.

[Equation 1] The remainder polynomial when divided by.

(107) The called station receives the connection request signal (108), that is, the control signal, from the standby state. (109) The called station side confirms that there is no carrier by carrier sense, and then (110) above (105)
The control signal unique to the called station is transmitted using the signal format of. (111) The calling station side receives the control signal response, that is, the connection response signal, and (112) the calling station side transmits the identification signal registered in advance to the called station side as a registration signal. (1
13) The called station receives the identification signal, and (114) checks whether or not the identification signal is registered in the called station in advance, and then "matches (YE
S) ”, the procedure proceeds to the remote control procedure. If“ mismatch (NO) ”, the communication is terminated to the called station side to the calling station side, and the communication is terminated. The general procedure when the communication is terminated is as follows (1)
The procedure after 18) is standard.

(116) If "match (YES)", the called station side is notified to the calling station side and the equipment control signal (remote control signal) of the calling station side is transmitted. (117) The called station receives the device control signal (remote control signal) from the calling station and controls the water heater, the heating device, and the like. At this time, a method may be used in which the answering station determines whether or not control is performed on the calling station side. (11

However, in the case of automatic channel switching by the frequency control channel as shown in FIG. 3, the empty channel selection and the empty channel are performed before the carrier sense in (104) above. After supplementing, the carrier sense of (104) is started. In the case of automatic channel switching by the frequency control channel, the operation after the transmission delay device transmission delay timer has elapsed is unnecessary. Similarly, the transmission pause time is unnecessary.

The signal (1) from the calling station side in the above (105)
Since the signal from the called station side in 10) is a signal determined when the device is manufactured and shipped, the signals in (105) and (110) do not change even if the identification signal registered in advance changes. By receiving the signals 105) and (110), the device itself can be specified.

In the wireless remote control method, the correction code of the registration calling signal or the control signal of the water heater, the heating device, etc. uses the error correction code structure shown below. The registration calling signal or the control signal is It is 63 bits or N times 63 bits. 63-bit basic configuration is a62, a61, a60
63 bits of a2.a1.a0. However, a62 to a0 are the coefficients of the terms from the 62nd order to the 0th order of the polynomial on the finite field whose order is 2 listed below.

[Equation 2] The remainder polynomial when divided by.

By using the above error correction code configuration, the signal logic unique to the device and the identification signal logic have the same or similar configuration, and the configuration of the wireless remote control device can be simplified.

Further, the registration calling signal or the frame synchronization signal of the control signal is a signal in which the order 2 of the frame synchronization signal of the signal of the line connection procedure is an inverted signal, that is, a frame synchronization signal in which 0 and 1 are inverted is used. Line connection procedure signal is 0001
In the case of 101110101000010010110011111, the frame synchronization signal of the registration calling signal or the control signal is 1110010001010111101101
It will be 101,100,000. By using the frame synchronization signal having the above configuration, the device-specific signal synchronization logic and the identification signal synchronization logic are made common, and the configuration of the wireless remote control device can be simplified.

In the above, the unique signal is used to identify the unique device, but it is also possible to use it as the key code for passing the identification signal.
