Problems solved by technology

[0002] At present, the automatic meter reading function of the electric energy meter usually adopts dedicated line communication methods such as RS485, that is, the data communication of the electric energy meter is a dedicated line, and the exchange of electricity information between the electric energy meter and the main station is also carried out through the dedicated line communication method. This kind of dedicated line communication In this way, another line must be laid out, the investment is large, and the post-maintenance cost of the line is also large, and the line is slightly damaged, which will affect the transmission and exchange of signals; in addition, due to the limitation of wiring, its use is small and limited to Trial in the community, unable to promote the application in a large area

Abstract

An electric energy meter utilizing HFC network to carry out information exchange consists of double - way communication circuit, multifunction special integrated circuit or CPU or MCU or DSP data processing controller, electric energy metering circuit, display circuit and power supply circuit. It can utilize HFC as double - way communication media to realize double - way communication between electric energy meter and main station.

Description

Technical field [0001] The invention relates to an electric energy meter and a communication method thereof for information exchange using an HFC network, and belongs to the field of electric energy meter wired communication device manufacturing. Background technique [0002] At present, the automatic meter reading function of the electric energy meter usually adopts dedicated line communication methods such as RS485, that is, the data communication of the electric energy meter is a dedicated line, and the exchange of electricity information between the electric energy meter and the main station is also carried out through the dedicated line communication method. This kind of dedicated line communication In this way, another line must be laid out, the investment is large, and the later maintenance cost of the line is also relatively large, and the line is slightly damaged, which will affect the transmission and exchange of signals; in addition, due to the limitation of wiring...
