摘要目前，利用GPRS网络实现的无线电力远程抄表系统、低压配电综合自动化系统的应用越来越广泛。而这些系统在长时间使用后，终端程序设计上的缺陷也就慢慢浮出水面，这就要求经常要对其终端设备软件进行修改或升级。而电力监控系统的特点是终端的地理位置距离较远、分散且工作环境较差，如果维护人员到现场进行软件升级，维护费用很高，而且不能及时进行更新。研究一种新的终端软件升级技术，就有着重要的现实意义。而远程IAP升级．利用了IAP编程的特点和GPRS无线网络，把要升级的程序分批下载到控制器中，再把这些代码利用IAP接口程序编程到Flash当中。这样实现了无线远程升级。因此为解决这一难题，本文针对远程配电监控终端,设计实现了基于GPRS的32位ARM7TDMIRISC处理器PLC1752作为主控制器的电力监控终端的系统软件远程升级及其优化方案，融合IAP(In Application Programming)技术实现电力终端系统程序的在线远程升级，这个方案有效地解决了地点分散电力监控终端设备软件远程升级问题。67643

Title Application Of Remote IAP In Power Monitoring Terminals Based On ARM7
Abstract
Nowadays, wireless automatic remote meter reading systems and automatic low volt electricity distribution systems such as transformer check systems, low volt meter reading systems, area meter reading systems and remote power systems switch systems are more and more widely applied. But these systems’ flaws in terminal program designs are revealed after long-term usage. So, the terminal equipment software needs to be updated. The character of power monitoring systems is that the terminals are geographic positions are remote and the working conditions there are tough. It will cost a lot and the update will not be in time if maintain crew members are sent to update the software. To solve this problem, this article, aimed at remote electricity distribution terminals, designed a software remote update program that used a 32-bit ARM7TDMIRISC processor which is based on GPRS. Combining IAP technology is used to realize remote update. This program solved the remote update problem in distant power monitoring equipment. The program will initialize the equipment, and decide if the software needs to be updated. If so, the sections in certain address in the FLASH of the terminal controller will be erased, reprogrammed and checked. The application will be updated to newer edition. The program in the terminal is mainly used to complete the sending of command to server or the receiving, checking, deciding, responding and storage of data. Some part of this software is written, compiled and debugged in the ADS developing environment. The software is written into the FLASH of the micro controller through JTAG interface.
