基于麒麟嵌入式操作系统的车载智能终端软件远程升级的设计与实现

为解决基于麒麟嵌入式操作系统的车载智能终端实际应用中的软件升级问题,提出了利用GPRS技术、IAP编程方式、应答机制、断点续传技术和校验机制实现嵌入式系统的软件远程升级方案,保证了数据传输的实时性、快速性、准确性和可靠性,并且通过各种实验模拟了升级过程中的异常情况,实验结果表明,所提出的方案能保证终端正确可靠地完成软件的远程升级,这也就验证了该远程升级方案的可行性.

Design and implementation of software remote updating in a vehicle-mounted intelligent terminal based on Kylin embedded operating system

In order to achieve the software remote updating of the vehicle-mounted intelligent terminal based on the Kylin operating system,a design is proposed.The GPRS technology,IAP method,response mechanism,technique of resume from transfer breakpoint and checkout mechanism were applied to the design to insure the real-time,veracity and reliability of during the updating process.A series of experiments were conducted to simulate the exception during the updating process.The results show that the software of remote updating of the terminal applying the design proposed can still complete exactly in all exceptional experiments.
