摘要
为提高灌溉用水利用率,缓解水资源日趋紧张的矛盾,采用基于ZigBee技术的无线传感网络与GPRS网络相结合的体系结构,基于CC2530芯片设计无线节点,开发了此节水灌溉控制系统。该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、无线网关、监控中心四部分组成,能实时监测土壤温湿变化,根据土壤墒情和作物用水规律实施精准灌溉。系统实现了节水灌溉的自动化控制,有助于改善农业灌溉用水的利用率和灌溉系统自动化的水平普遍较低的现状。
In order to improve the utilization of irrigation water,and ease the growing tension of water conflicts,a water-saving irrigation control system is introduced, which integrates the ZigBee wireless sensor network technology and GPRS network,designs wireless nodes based on CC2530. The system, which is controlled by single chip microcomputer has four major components： wireless sensor nodes,wireless routing nodes,wireless gateways and control centers. It can be real- time monitoring of soil temperature and humidity changes,and it is based on soil moisture and crop water law for precision irrigation. The system automatically controls water based on crop irrigation water, which can help to improve the utilization rate of agricultural irrigation water and the low level of automation of irrigation systems.
