摘　　要：为了节约农田灌溉用水,提高水资源的使用效率,提出了一种基于无线传感器网络与GPRS网络相结的农田自动节水灌溉远程监控系统,该系统由中央监控计算机、灌溉监测控制器、无线传感器网络、GPRS模块和阀门控制器组成。系统以单片机为控制核心,由无线传感器节点、无线路由节点和无线网关实时监测土壤含水率变化,根据土壤含水率和农田用水规律实施精确灌溉。系统实现了节水灌溉的自动化控制,改善了农业灌溉水资源的高效利用和灌溉系统自动化水平。实验结果表明,整个系统的伸缩性较好,当土壤含水率太高或某种因素导致某些传感器节点损坏,系统中的其他部分仍能持续正常工作,具有自组织重新恢复的功能。监控中心能够实时地显示出各节点的土壤含水率参数和阀门的启停状况,实现节水灌溉的远程监控。In order to save field irrigation water quantity and improve the water use efficiency,a remote monitoring system for field water-saving irrigation based on wireless sensor network and GPRS is presented in this paper.The system consists of central monitoring computer,irrigation monitoring controller,wireless sensor network,GPRS module and valve controller.The single chip computer is the control core of the system,the soil water content is monitored through wireless sensor node,wireless route node and wireless gateway,and the accurate irrigation is implemented according to the soil water content and field water demand.It realizes the automatic control of water-saving irrigation and improves the agricultural irrigation water use efficient and automation level of the irrigation system.The experiment results show that the whole system scalability is good.Even some sensor nodes are damaged for the too large volumetric water content of the soil or other factors,the other parts of the system can still continue to work.It has restore function and can reorganize.The monitoring center can real time display the soil water content of nodes and the status of valves,and realizes the remote monitoring of water-saving irrigation.
