摘要
设计一种基于PLC的消防供水控制系统。系统具有手动/自动两种工作方式,自动方式下,由PID控制器调节变频器的输出频率,控制水泵电机的转速,调整供水流量,从而维持管网水压恒定。系统经调试已投入实际运行。
A kind of water supply for fire system based on PLC is matic.ln automatic mode, the output frequency of inverter is controlled and the water flow is adjusted,so water pressure debugged and put into practice. designed.The system has two working modes：manual and auto- regulated by the PID controller.The water pump motor speed is of pipe net can be maintained constant.The system has been
