基于ARM的电力负荷管理终端设计

摘要

This article will bring forward load terminal,its CPU uses ARM 32 bit LPC2138 chip which has strong functions,high applied integration.Terminal communicates home site through GPRS,using MC55 module that is simple application and exploitation.Terminal calculates not only 485 multifunctional meters,but also some foreign meters.Especially adding to a function of electricit-stealing prevention,availably solves electricity-stealing problem.%本研究设计的电力负荷管理终端的CPU采用ARM32位的LPC2138芯片,该芯片功能强大,应用集成度高;终端与主站通过GPRS通讯,采用MC55模块,应用开发简单;该终端不仅可以抄录485多功能电表,还能抄录兰吉尔、红相、ABB等外国电表;更重要的是增加了防窃电功能,有效解决了收电费难及偷电等社会问题。
