摘　　要：笔者设计了一套基于S7-200系列PLC控制的二次加压站供水系统,该系统在具有自动开停机程序的同时还配有定时休眠功能,可以根据当前机组的运行时间对其强制休眠,避免设备运行时间过长造成损耗。此外,该系统还配有强制唤醒功能,若此时需要开机而当前机组却在休眠时间内,可以对其唤醒使其立刻投入运行,从而实现对设备的合理利用,延长机组使用寿命。The author designs a water supply system of secondary pressure station based on S7-200 series PLC control.The system is equipped with automatic start-stop program and timing sleep function,which can be forced to sleep according to the running time of the current unit,so as to avoid the loss of the equipment due to the long running time.Also equipped with forced wake up function,if the need to start at this time and the current unit is in hibernation time can wake up to make it immediately put into operation,can realize the reasonable use of equipment,prolong the service life of the unit.

关 键 词：PLC控制 自动投切 定时休眠 强制唤醒
