Abstract
PURPOSE:To perform high-precision signal transmission by binary-modulating the electricity of an AC power source, by superposing a signal on the number of waves of the AC electricity, and by using the energy of the AC electricity as electric power for the operation of terminal equipments. CONSTITUTION:In a binary-signal output unit 13c, a binary signal generated by a binary-signal output circuit 131c is supplied via a driver 133c to a modulating circuit 134c, which modulates the output electricity of an AC power source 11 to send the result to the contact operating equipment 31c of a terminal part 3 through a transmission line. The contact operating equipment 31c receives the transferred signal through a transformer 311c, and restores it to the binary signal through the demodulation of a demodulating circuit 313c, operating a relay 315c, etc., in accordance with the obtained signal. Thus, high-precision signal transmission is performed.
