摘要
本文主要是针对家庭用户设计了一单相电能计量电路。此电路采用一款高精度单相电能计量芯片ADE7755来采集用户所使用的电量,并使用高性能的单片机AT89C51来作为整个电能采集电路的控制中心。文中给出了整个电能计量电路的组成框图、单相电能测量电路图以及软件流程图,最后介绍了试验情况并对试验结果进行了分析比较,通过实验表明该电能计量电路具有较高的测量精度。
This paper designs a single-phase power measurement circuit for home users. The circuit adopts a high-precision single- phase energy metering chip ADE7755 for the acquisition of the electrical energy, and uses the high-performance SCM AT89C51 as the control center of the circuit. This paper also introduces the working principle schematic, and the diagram of the components of the energy metering circuit as well as the software flow chart. At last, this paper introduces the test and analyzes and compares the testing results, which shows that the energy metering circuit with high precision.
