摘要
计算机应用系统在后期维护中需要修改或更新应用程序。在野外使用传统的方法升级固定的应用系统前,需要在现场进行打开设备、手工安装跳线等繁琐过程。为了改变这一现状,设计了一种基于IAP程序远程更新方法,该方法主要通过GPRS网络进行远程在线升级。本文介绍了交通信号灯运维装置的整体实现框架,详细阐述了IAP程序更新原理,并以STM32F107单片机为例描述了单片机FLASH的分区以及IAP程序设计。验证结果表明,IAP能够实现交通信号灯运维装置的远程程序升级。
The computer application system needs to modify or update the application program in the later maintenance.It is necessary to open equipment and install jumper manually and other tedious processes before upgrading fixed application system with traditional methods in the wildness.In order to change the condition,a novel approach to update remotely based on IAP program is proposed in the paper.This method is mainly used for remote online program upgrade through GPRS network.In the paper,the overall framework of traffic light operation and maintenance device is introduced.The principle of IAP program update is described in detail and STM32F107 MCU is taken as an example to describe the MCU FLASH partition and IAP program design.The verification results show that IAP can realize remote program upgrade of traffic light operation and maintenance device.
