ONE-WAY COMMUNICATING APPARATUS BY USING POWER LINES

摘要

PURPOSE: A one-way power line communication device is provided to simplify controlling processes by installing a transmitter with a phase-controller at one line of AC commercial power lines to detect a waveform and using the waveform as a controlling signal. CONSTITUTION: A transmitter includes a switch and a phase-controlling circuit in parallel connection with the switch. An EMI filter and a radio-wave rectifier(120) are in connection with the transmitter. A receiver(140) implements full-wave rectifies the output of the transmitter. A microcomputer(150) inputs the signal of the receiver and controls loads. An energy compensating circuit(170) uses the signal of the receiver as input.
