摘要
本文利用Watchdog技术,检测微机控制系统程序运行出错及程序自动恢复运行,给出了硬件及软件实现实例,采用本方法,可大大提高工业控制系统的可靠性。
In the paper, the program executing errors of the microcomputer control system are checked and the orogram is automatically restored to execute by using the watchdog technique. The hard-ware and software implementing examples are given. The reliability of the industry control sys-tem is largely risen by using this method.
