摘　　要：针对分散型测控系统中终端系统软件升级和维护困难的问题,提出一种以GPRS网络作为通信链路,采用应答机制、断点续传和IAP等技术,实现了对分散型测控系统中终端系统软件的远程在线升级.实际应用表明,该设计方法具有高效、高可靠性的特点,可显著提高分散型测控系统中终端系统软件升级的便利性,大大缩短系统的维护周期、降低维护成本.The remote upgrade and the maintenance of the large-scale DCS terminal systems software are difficult, in view of this question, it proposed a method that uses the communication link by the GPRS network, and it uses the technologies of the reply mechanism, resume broken transfer and IAP to realize the online upgrade and maintenance of the DCS terminal system software. The practice proved that this method has the characteristics of high effectiveness and high reliability, it can obviously enhance the convenience of the largescale DCS terminal system software upgrade and maintenance, it can shorten the maintenance cycle and reduce maintenance cost of the system greatly.
