Abstract

PURPOSE:To facilitate an execution of wiring greatly and to reduce the cost by utilizing a remote control system and by transmitting a sensor output to a signal line, shared among sensors, after converting it into a high frequency signal. CONSTITUTION:One terminal equipment 2 is arranged near one sensor 4 correspondingly. With a control output when terminal equipment 2 is called by master equipment 1, the connection of the output of transmitting unit 5, having received the output of corresponding sensor 4, with signal line 3 is controlled to turn on-off contact 9 according to the control output of terminal equipment 2. Unit 5 performs the voltage/frequency conversion of the output signal of sensor 4 into a high frequency signal, which is superposed upon signal line 3 via contact 9. Master equipment 1, on the other hand, is provided with analog signal reception part 6 to receive the high frequency signal. From address data set at that time, master equipment 1 knows which sensor 4 has the output corresponding to the high frequency signal and then detects the output data of sensor 4 by the frequency.
