摘　　要：本文首先介绍了基于定时器的工控机受干扰后自动重起动的普通方法。然后给出了基于可重置位单稳、带输出口锁定、以及带输出口和备份ＲＡＭ存储器双重锁定的高可靠程序重起动技术，以及应采用的程序结构。in this paper,the author has at first introduced a common PROGRAM AU-RESTART technology after interferenced based on timer, and then give out three more efficious and reliable metheds based on: (1)Dual retriggerable rnonostable;(2 )Dual retriggerable monostable and output-port locking; (3) Dual retriggerable monostable, output-port and RAM locking. and softwere structure that you should accept when you use these methods.
