摘　　要：针对目前市场上的北斗终端程序现场升级与维护困难的问题,论文设计了一种基于IAP的北斗终端程序远程升级方案。该方案系统地研究了基于STM32的IAP关键技术,同时提出断点续传、TEA加密以及双链路的设计思想,从而实现北斗终端程序远程在线实时更新。测试表明,该方案解决了北斗终端需要硬件下载器进行现场升级程序的不便,并提高了北斗终端远程程序升级的安全性与纠错能力,对北斗终端的推广有一定的现实意义。Aiming at the problem that it is difficult to field upgrade and maintain the Beidou terminal program in the current market,the thesis designs a remote upgrade scheme of Beidou terminal program on the basis of IAP.In the design,it systematically studies STM32programme on account of the key technology of Internet access provider(IAP)and also puts forward the design concepts of breakpoint resume,TEA encryption and decryption and dual-link,which achieves the function of remote online real-time update of Beidou terminal program and greatly improves the stability in the process of transmission.Test shows that this scheme overcomes the shortcoming of Beidou terminal that hardware downloader is required to field upgrade the program and increases the stability of Beidou terminal program in the process of remote upgrade,which has b practical significance for popularizing Beidou terminal.
