摘要
利用Analog公司2005年生产的电能计量专用芯片ADE7758设计一个三相电能表,采集数据准确,控制性能灵活且性价比高。本文阐述了基于ADE7758和STC89C52的电表的整体设计及工作原理,重点讲述ADE7758电能计量芯片的外围设计以及与STC89C52的通信连接。使用模块化思想和嵌套方法分别对硬件进行设计、对软件进行编程。
The three-phase watt-hour meter is designed based on the electric energy testing chip ADE7758 which is produced by Analog at 2005. It has some advantages such as data collection accuracy, control flexibility and cost-effective. This paper details the whole designed of power meter and its working principle, focusing on the peripheral circuits of ADE7758 and its serial communication with STC89C52. Blocking design idea and nested method had been considered in hardware designing and software programming.
