摘　　要：为了掌握电网运行状态,对其进行监控和保护,首先要准确地获得电网各项实时电参数。为此,设计了一种基于ARM7处理器LPC2132和6路14位同步采样芯片AD7657的电参数采集平台,给出了二者的接口,同时介绍了平台硬件部分的存储扩展模块、显示模块及通讯模块的结构,最后给出了调试通过的程序流程图。该平台具有良好的实用性,可应用于需要实时高精度测量电参量的领域。To monitor the working status of power grid and to monitor and protect it , the electrical parameters must be sampled accurately at real time.This paper presentes a design of electrical parameters acquisition platform based on ARM7 processor LPC2132 and six channel 14-bit synchrony acquisition chip AD7657. The interface between them was designed. Meanwhile, the hardware of platform including the memory expending part, the display part and the communication part was introduced. Finally, the process flow chart debugged successfully is given. This platform is good practical,and can be applied in many field that the electrical parameters need be measured in a realtime and high precision condition.
