无线传感器网络在农田节水灌溉系统中的应用

Application of Wireless Sensor Network in Field Water-Saving Irrigation System

针对农田节水灌溉的需要,提出了把无线传感器网络应用于农田节水灌溉系统的思路和农田节水灌溉系统设计方案,该灌溉系统由农田监测区域的无线监测网络和远程监控中心组成,可对农田需水信息变量进行实时监测。介绍了系统的总体架构,设计开发了无线传感器网络节点、基站以及软件流程。该系统采用了无线传输的方式,解决了有线通信方式所存在的难以升级、难以扩展等问题,具有低功耗、低成本、扩展灵活等优点,在农业节水灌溉方面具有广阔的应用前景。

According to the demand of field water-saving irrigation,this paper presents a new idea including the application of wireless sensor network（WSN） for field water-saving irrigation system and a design scheme of field water-saving irrigation system.The irrigation system consists of wireless monitoring network in field monitoring zones and remote monitoring center,it can real-time monitor the field water requirement information variables.In this paper,the system framework is given,the network nodes and station are designed and the software process is given.Because of using the wireless data transmission,the system solved the existing problems for upgrade and expanding.Moreover,the irrigation system has the advantages of low power,low cost,agile expanding,and so on,it will possess a widely application foreground for agricultural water-saving irrigation.
