摘要：Disclosed is a system of transmitting and receiving control signals for varioustypes of indoor devices using the existing power wiring in houses and buildings. Thetransmitter section of the power wiring transmission system is provided with a circuit inwhich the output of a sine wave oscillator (1) is fed to an emitter-follower (5. 6) through aphotocoupler (2) and this output is then fed to the indoor power distribution linethrough a series resonance circuit (8, 9) after stepping down with a transformer (8); thereceiving section is provided with a circuit in which the signal from the distribution line isfed to a parallel resonance circuit after passing through a series resonance circuit.Moreover, the input and output sections of the receiver are resistor terminated.
