基于ENC28J60的远程三相电能表的设计与实现

The Design and Implementation of Remote Three-phase Multiple Energy Meter that Based on A ENC28J60

针对传统的电量采集处理系统抗干扰能力差,功能单一的缺陷,提出了一种采用专用电能计量芯片CS5460A的三相电量采集系统,利用CS5460A进行电量采集,P89LPC932单片机做数据处理,通过Serial Peripheral Interface(SPI)端口传送电流、电压、有功、无功等实时测量值,并用以太网控制器ENC28J60,实现以太网通信,配合上位机显示,对电能进行集中管理。

As to the weak antijamming capability and the single-function of tradition electricity acquisition and processing system, a three-phase electricity acquisition system which is imposed have specify kWh_chip CS5460A is presented. By using a CS5460A to electric gathering and adopting an P89LPC932 to data processing.It can transmit real-time measured values of various electric quantities from Serial Peripheral Interface （SPI）. By using Ethernet controller ENC28J60, it can realize ethernet communication and power centralized management on upper computer.
