摘要
由于嵌入式操作系统的广泛采用,对系统的可靠性要求很高,尤其以一些计算机软件作为控制核心的系统,如数控机床、机器人、自动化设备等,如果系统在出现故障时,会出现一些严重的后果,为了避免不必要的损失,在此可以利用看门狗自动恢复。介绍了看门狗的基本原理,以及软件的具体实现。
Because of broad adoption of embed system, the reliability of system are required highly. Example numerical control machine tool , robot , automation equipment etc, If the system fails, there will be some serious consequences. If there is trouble in system, watchdog can come back it.
