介绍了 ADE7755内部结构及信号流向，在电能计量和数字信号处理理论研究的基础上，以 ADE7755为计量芯片，设计了一套智能电网电能计量模块。其中电流电压采样实现了将电网中的不可直接测量的大电压/大电流转换成可以用来测量的小电压/小电流。该系统能直接输出数字信号给单片机，能直接检测出家庭的用电功率和用电量。同时，对该模块做了相对严谨的实验，并将实验数据进行对比分析。经过测试，该计量模块可以直接用于智能电表的生产和智能电网的建设。

This paper introduces the internal structure and signal flow of ADE7755 . Based on the research of electric energy measurement theory and digital signal processing theory , taking ADE7755 as the measurement chip , the paper designs a smart grid electric energy measurement module . Voltage and electricity converts the high voltage and electricity to low ones that can be measured . This system can directly output digital signals to single chip microcomputer and detect the power capacity and power consumption of the family . At the same time , the relatively precise experiment is done on the module , and the experimental data are analyzed and compared . After testing , the measurement module can be directly used in production of smart meters and the construction of smart grid .
