摘　　要：针对大型分布式监控系统远程终端的嵌入式系统软件远程在线升级和维护问题,提出一种基于通用无线分组业务(General Packet Radio Service,GPRS)的嵌入式系统软件的远程在线升级方案,该方案采用GPRS、应答机制与断点续传技术,保证数据远程无线传输的准确性和可靠性,应用RAM分区技术和IAP技术实现系统软件的在线升级。实践证明,该设计方案具有在线升级成功率高、速度快的特点,已成功应用于南京航道局的航标自动监测系统中。The remote upgrade and maintenance of the remote terminal＇s embedded system＇s software of large-scale distributional control system are difficult,a plan that the remote on- line upgrade of embedded systems software based on GPRS is proposed,it uses the technologies of GPRS,the reply mechanism and resume broken transfer to ensure the accuracy and reliability of the data remote and wireless transmission,it uses the technologies of RAM partition and IAP to realize the on-line upgrade of system＇s software. The practice proves that this design project has the characteristics of on- line upgrade successfully with high ratio and quick speed, and the design project is applied successfully in the navigation observation systems of Waterway Bureau of Nanjing.
