摘　　要：随着工业控制计算机在工业生产控制领域应用越来越广,而且常工作在无人值守或条件恶劣的工作场合,要求具有抗震、防尘、防潮、防电磁干扰等特点,工业控制计算机受输入电源不稳定性干扰,容易出现掉电后无法自动开机的现象.文章提出一种工业控制计算机掉电自恢复运行方法,通过硬件设计、软件复位等流程设计,解决当前工业控制计算机掉电无法自动开机运行以及维护效率低下等问题.With the widely application of IPC in the field of industrial production,and often work in unattended or poor working conditions,which requires seismic,dust,moisture,electromagnetic interference and other characteristics,IPC disturbed by the instability of input power supply,and it’s easy to fail to start automatically after power failure.In this paper,a method of power-off self recovery operation of industrial control computer is proposed.Through the design of hardware connection,software reset signal,the current problems of power-off failure of industrial control computer and low maintenance efficiency are solved.
