摘　　要：介绍一种应用于工业控制系统的电源自动监控电路。该电路不仅能使工控系统在掉电时自动保护现场数据，而且能区分电源的正常下电和瞬间脉冲干扰，并有效地避开干扰，待电源正常自动恢复程序运行，保持系统运行的连续性和稳定性。An automatic power supply monitor is introduced in this paper.It can be applied to industrial control systems,ensure them to preserve running data when power supply goes off and to resume their execution when power supply recovers normal.By employing the monitor,industrial control systems can distinguish pulse interference in power supply form normal power off and ignore it.Therefore the continuity and stability of the execution maintain can be maintained.
