SYSTEM FOR CONTROLLING POWER LINE COMMUNICATION THROUGH FLOOR WIRING

摘要

PURPOSE: A power line communications control system is provided to prevent unnecessary power consumption by secluding the stand-by power of a load device and to easily construct an inter-layer power line. CONSTITUTION: A three phase power line is branched from the branch box of an inter-layer. A local control apparatus(20) is connected with the three phase power line and branches a power source which is provided. A floor wiring(30) is connected to the local control apparatus. A switch and an electrical socket supplies the power source to a load device. A controller indicates used power about the load device which is connected to the switch and the electrical sock by receiving a data signal which is transferred from the local control apparatus. The controller secludes and restores stand-by power by controlling the local control apparatus.
