摘要
农田墒情信息是现代农业实施精准施肥、精确灌溉的重要科学依据。为了实现快速准确地采集墒情信息,研究开发了基于3S(GPS/GIS/GPRS)技术联合的农田墒情远程监测系统。该系统主要由农田信息监测网络节点和远程服务器组成,在小范围内由传感器节点基于ZigBee通讯协议组成无线传感器网络,在大尺度上通过网关节点集成GPS网络,利用GSM/GPRS网络实现与Internet的信息交互,完成了墒情数据的自动采集、无线传输和准确定位。设计了太阳能自供电的长寿命无线传感器节点和网关节点,开发了服务器端农田墒情信息管理系统软件,实现了Web方式下的参数远程设置和信息实时监测。该系统的设计开发为农田墒情信息监测和分析决策提供了有效的工具。
Soil moisture information is an important scientific basis for precision fertilization and irrigation in the modern agriculture.In order to acquire this information rapidly and precisely,a specific design of the remote monitoring system for soil moisture based on 3S（GPS/GIS/GPRS）technology alliance was proposed.This system consisted of the monitoring network nodes and a remote system server.By means of the ZigBee-based wireless sensor networks within a small scale,the GSM/GPRS/GPS networks within a large scale and their mutual communication with the worldwide internet,this system implemented advanced functions such as automatic data acquisition,wireless transmission and nodes orientation.Besides,long-duration solar-powered wireless sensor nodes and sink nodes were designed.The information management software running on the system server was developed for setting remote parameters and monitoring real-time data.This system may play an effective role in soil moisture information monitoring and decision-making analysis.
