As shown in FIG. 2, the signal is modulated by the modem 2 and passes through the signal line L1 , which is usually several hundred meters long, as shown in route A in FIGS. The third
The opening/closing control signal as shown in Figure A begins to be transmitted from time t0 and is transmitted until time t1 . On the other hand, the switch that has received the opening/closing control signal starts transmitting an opening/closing status signal to the remote control device 1 as the opening/closing status signal shown in FIG. 3B at time t 2 delayed by Ta time from the aforementioned time t 1 .
Then, the open/close state signal passes through the signal line L 3 as shown in route B in FIGS.
The signal is supplied to the modem section 2 via the coupling capacitor CC, the coupling filter CF, the receiving section 3b, the amplifier RAMP, and the signal line L2 , and after being demodulated by the modem section 2, it is sent to the remote control device 1. The transmission ends at time t3 .

ることができる。 On the other hand, an inspection data signal is sent out at the same time as the opening/closing control signal sent from the remote control device 1 to the switch 4. After this inspection data signal exits the output end of the transmitting section 3a in the coupling section 3,
Branched at the input of the inspection loopback circuit 3c,
As shown in route C in Figs. 1 and 2, the signal passes through the attenuator ATTL of the loopback circuit 3c and the bandpass filter BPFL that passes only the inspection data signal, is amplified by the amplifier RAMP, and is sent to the modem via the signal line L2 . The signal is demodulated in section 2 and looped back to remote control device 1 until time t2 . At this time,
The looped back signals are looped back to the remote control device 1 through signal lines L1 , L2, etc. with a slight delay from the opening/closing control signal, as shown in FIG. 3C. In this way, the opening/closing control signal and the inspection data signal are transmitted at the same time, and only the latter signal is looped back through the band pass filter BPFL via the above route, and the opening/closing control status signal is determined from the sign state of the returned signal. The remote control device 1 determines whether the signal is an inspection data signal. This allows you to check the operating functions of each part, and then
It is possible to improve the reliability of the sent open/closed state signals.

The monitoring process of the switching control state signal of the switch 4 is carried out by performing the receiving process after a time Ta has elapsed after the end of transmission (time t 1 ) shown in FIG. 3A, thereby selecting the signal.

認できる効果がある。 As described above, according to the present invention, when transmitting the switching control signal and the inspection data signal from the remote control device to the switch at the same time, the inspection data signal is transmitted via the inspection loopback circuit provided in the coupling part. Since the data signal is sent back to the remote control device for judgment, there is an advantage that the operating function of the analog circuit of the modem section and the coupling section can be checked before the open/close state signal is sent.
