Abstract

PURPOSE: To prevent malfunctioning by correcting the time lag of the zero cross point detection through the software of a microprocessor with detection of the zero cross point half in cycle of the power frequency by a switching element such as transistor.
CONSTITUTION: To an indoor power line l following a block filter 3, connected are transmitters 41, 42 ... for generating a carrier control signal to control load such lighting apparatus and information device and receivers 61, 62 ... for controlling various loads 51, 52 ... upon reception of the carrier control signal of the transmitters. Zero cross points half in cycle of the power source frequency are detected by a switching element and the detection signals are turned on or off every half cycle. The rise or breaking time is discriminates by arithmetic processing of a microprocessor to the zero cross point and determine the abnormalty of the waveform of the power source.
