摘要
文章介绍了一种沙地节水渗灌自动控制系统装置，主要叙述了渗灌装置的结构组成与连接方法，以及系统的软、硬件组成与仪器功能指标，整个系统设计简洁，成本低，可靠性好，能自动监测沙地水分上下限和渗坛水位上下限，根据所需信息系统自动向管道供水，大幅度减轻操作人员的劳动强度。采用微机技术有利于农业现代化管理。
An autonomously controlling system fo r water efficient infiltrating irrigation is introduced. The constitution and a ssembling proceeding of the system as well as its supporting software and hardwa re, and the function indicators are detailed in the paper. The system is coming with easy design, low cost and high reliability. It can autonomously monitor the upper limit and the lower limit of soil moisture in sandy land and water tabl e in percolating pot. Based on the needed information the system will supply w ater autonomously, which can reduce labor intensity considerably. The autonomous ly controlling system is favorable for the modernization management of agricultu re by appling computer technology, which is worthy of popularization in water e fficient agriculture.
