Abstract: |
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. |
