POWER LINE COMMUNICATION IN ELECTRIC CHARGES DISPLAY SYSTEM

摘要

PURPOSE: An electric charge display system using a power line communication is provided to give a user motivation of saving energy. CONSTITUTION: A smart meter(5) is connected to a first electric line(3), collects the electric energy of a household appliance(1-1), and transmits the collected electric energy. A PSM(Power Supply Management) gateway(9) is connected to internet and a second electric line(7), collects the electric energy from a smart mete, and transmits electric charge according to power consumption. An IP-TV(13) is connected to a third electric line(11), displays power consumption and electric charge from the PSM gateway.
