中文摘要：

针对农田灌溉中管理粗放、信息化和智能化程度低、灌溉水利用效率不高的问题,研究设计一个基于ZigBee无线网络的智能节水灌溉系统。系统采用CC2530无线收发模块,将土壤含水量经LPC932单片机处理后传送到PC终端,用户可查看并根据所监测土壤含水量与灌溉临界值判别的结果决定是否自动打开和关闭电磁阀实施实时灌溉。该系统具有采集数据准确、组网快、成本低、功耗低等特点,成功实现农田智能节水灌溉。

英文摘要：

Aiming at the problems of farmland irrigation such as extensive management,low degree of information and intelligence,and low efficiency of water utilization,an intelligent irrigation system based on ZigBee wireless network was designed.Water content of soil can be processed by LPC932 single chip microcomputer,and sent to PC users through the wireless transceiver module（CC2530）.Thus,according to the measured information,users can decide whether turn on or off the electromagnetism valve automatically to implement irrigation.This system,with advantages of accuracy data collecting,fast networking,low cost,low power consumption and so on,successfully realizes intelligent operation of water-saving farmland irrigation.
