摘　　要：针对滴灌系统中一台水泵控制的干管与多条支管相通、开启支管数目的不同,供水量和时间多变这一特点,在滴灌系统中引进了变频调速恒压供水系统。为此,主要阐述了供水系统的组成原理、硬件电路的设计以及系统软件的设计,解决了滴灌系统因开启支管数目不同而导致管网压力不稳定的问题。Total conduit which is controlled by a pump is interlinked with several water pipe in the drip irrigation system.It is different that water supply of quantity and time because of the different number of opening conduit.It fundamentally solved the problem that variable frequency speed regulation and constant pressure water supply system,it＇s to keep the constant pressure water supply when opening some water pipe at the same time in the drip irrigation system.This paper introduces the constitute of the drip irrigation frequency conversion of constant pressure water supply.

关 键 词：滴灌 变频调速 PLC 恒压供水
