Three-phase electric energy meter system

Abstract

The invention belongs to the electronic circuit technology field and provides a three-phase electric energy meter system. The three-phase electric energy meter system comprises a metering module, a communication module, a main control module and a power supply management module. Voltage and current acquisition is performed on an electric signal output by the metering module to a three-phase powersupply so as to acquire multiple real-time measurement parameters. And data interaction with external equipment is performed through the communication module. Therefore, the three-phase electric energy meter system can intelligently acquire real-time measurement parameters and exchange data with the external equipment, intelligence is enriched, a user experience is improved, and the three-phase electric energy meter system is simple and easy to design. Meanwhile, a user can consult data which needs to be checked through a button and a LCD screen; and the three-phase electric energy meter system can automatically detect intensity of an external magnetic field and prevent electricity stealing, and problems that an existing three-phase electric energy meter technology is tedious in design andpoor in intelligence and cannot realize communication with the external equipment under certain conditions are solved.

Description
