【摘要】Considering the difficulties of the software upgrading and maintenance of data acquisition terminal,a remote upgradable data acquisition terminal is designed.The terminal can communicate with sever on the internet via GPRS（General Packet Radio Service）modem.The client on the other side of internet will upgrade the terminal through the server.The theory of self-programming on Atmega128 and the operation mode of GPRS modem named MC37i are introduced in detail.The hardware design and the software are discussed.The system has been proved to be workable and stable.%随着微控制技术的发展,单片机在工业领域得到广泛的应用,但是由于工作环境恶劣使得对单片机的升级维护存在很大的困难。针对这种问题,提出了一种基于GPRS （General Packet RadioService）的单片机远程升级的方案。单片机借助GPRS（通用无线分组业务）模块连接到Internet上的服务器,远程客户端通过访问服务器实现与单片机之间的数据通信。借助于单片机内部的自编程程序,即可实现单片机程序的远程升级。介绍了单片机Atmega128的自编程原理以及GPRS模块的通信机理,并详细说明了系统的软硬件设计。经过验证,方案运行可靠,稳定。
