摘要：我国是传统的农业大国,目前正处于现代农业快速发展阶段,传统农业管理 已经满足现代生活对粮食作为的需求所以需要用现代科学技术对传统农业进行 现代化强化与改造。农作物生长的快慢取决于很过因素,其中土壤是农作物生长 的基础。本文在分析当前国内外农田土壤监测系统研究状况的基础上,针对江淮 地区农业结构的特点,将无线传感网络、移动通信和互联网等多项技术融合,提出 了一种基于无线传感网络的农田土壤监测系统设计。设计了一种基于无线传感器 网络的农田环境监测系统。 该系统利用传感器节点采集农田环境参数后，通过 ZigBee 技术发送到控制中心，再对数据进行分析和处理，使农田管理者能精确 直观地了解农作物种植过程中的关键参数，了解农作物的生长情况和土壤的健康 程度，具有很好的实用价值。91783

Abstract: China is a traditional agricultural country, is currently in the stage of rapid development of modern agriculture, traditional agricultural management has to meet the needs of modern life as food so the need for modern science and technology to modern agriculture to strengthen and transform the modernization。 The speed of crop growth depends on factors, where the soil is the basis for crop growth。 Based on the deep analysis of the current research situation of farmland soil monitoring system at home and abroad, this paper puts forward a new technology based on wireless sensor network, mobile communication and Internet, which is based on the characteristics of agricultural structure in Jianghuai area。 Design of Farmland Soil Monitoring System。 A farmland environmental monitoring system based on wireless sensor network is designed。 The system uses the sensor node to collect farmland environmental parameters, sent to the control center through ZigBee technology, and then the data analysis and processing, so that farm managers can accurately and intuitively control the key parameters of crop cultivation process, to understand the growth of agriculture as a situation And the health of the soil, has a very good practical value。 tKeywords: wireless sensor network; soil monitoring;; sensor node; real-time monitoring; ZigBee
