Automatic meter reading method using power line communication(plc) through a neutral line

A remote checking method of power line communications base is provided to check all kinds of the meters like a power, a gas, and waterworks of a consumer using an inductive coupler. A data meter-inspected in a consumer(100) is transmitted to the first data acquisition unit by the low-voltage power line(110) communications. Data collected in the first data acquisition unit is transmitted to the second data acquisition unit of high position by the power line communications using a ground wire(140) installed in an electric pole. The second data acquisition unit unites with an optical cable, a coaxial cable, a telephone and a communications exclusive LAN installed for data communications of the high speed communications exclusive back born(103). The second data acquisition unit delivers the collected data to a remote checking server(104).
