The overall design scheme was introduced, and the three - layer control model of the system based on RS485 bus structure was presented. The method of power - detecting was discussed. Each main hardware module, including MCU and IC ADE7757 was studied. And at the same time, the software programming method was recommended. The key technology and optimization method were also expounded. The results of the test indicate that the system is simple and reliable and is applicable in linear load and nonlinear load system. And it can also implement the system automation control with lower cost and high efficiency.
