Control system for suppling power by power line communication
First Claim
1. A power supply control system using power line communication, comprising:
- a repeater means for recognizing a remote control signal transmitted by a predetermined remote control signal transmitting means and an ID number of an electronic equipment corresponding to the remote control signal in order to remotely turn on/off at least one electronic equipment selected among a plurality of electronic equipments;
a power line signal transmitting means for converting the ID number of the electronic equipment and the remote control signal recognized by the repeater means into a predetermined data signal, and interfacing with a power line signal of AC power to transmit the converted data signal;
a power line signal controller having a PLC (Power Line Communication) unit for isolating the data signal transmitted by the power line signal transmitting means from the power line signal of AC power, and converting the data signal into a digital signal; and
a relay means integrated with the power line signal controller and included in the electronic equipment so as to control a power source supplied to the electronic equipment by connecting or disconnecting a power source terminal to/from a load terminal under the control of the power line signal controller, the relay means being connected to the PLC unit through a contactor.
