摘　　要：为了实现恒压供水,主控制器是可编程逻辑控制器(PLC),而完成变频调速恒压供水系统的硬件和软件设计的执行器是变频器。实现对管网压力的准确收集,并自动调节特定泵的速度以及多个泵的输入和取回,以使管网主管的出口端的压力基本上在一定范围内。保持在。本文主要分析PLC在农田灌溉恒压供水控制中的应用。In order to realize constant pressure water supply, programmable controller (PLC) is used asmain controller and frequency converter is used as actuator to complete the hardware and software designof frequency conversion constant pressure water supply system. The accurate collection of pipe networkpressure, the automatic adjustment of the speed of a pump and the input and exit of multiple pumps, sothat the pressure at the outlet end of the main pipe network is basically maintained in a certain range.Application of PLC in constant pressure water supply control of farmland irrigation is analyzed.
