ELECTRIC ENERGY AUTOMATIC METERING SYSTEM WITH INFORMATION COMMUNICATION FUNCTION

PROBLEM TO BE SOLVED: To ensure security, reduce attenuation at a power line carrier communication, and make an electric energy automatic metering system with information communication function easy to introduce to collective dwelling with respect to the electric energy automatic metering system equipped with information communication function, in which the power line carrier communication is used in common for automatic meter reading of used electric energy in each home of a collective dwelling and also for communication of another information other than the electric energy of each home. SOLUTION: Used electric energy measured with a watt-hour meter 26 in a home 3 is transmitted through a measured electric energy sending-out terminal board 26T3, an adaptor 253, a PLC slave unit 251, a PLC master unit 23 to an automatic meter reading line 4. In the electric energy automatic metering system equipped with information communication function, an in-home PLC device slave unit 28 is connected through a domestic electric distribution panel 27, a load-side power watt-hour meter terminal 26T2 of the watt-hour meter 26, an in-home PLC device master unit 252, the PLC slave unit 251, and the PLC master unit 23 to a communication line 11 for information other than the electric energy.
