摘　　要：为了节约农田灌溉用水,提高水资源的使用效率,应用计算机技术、自动化控制技术于农田灌溉系统。结合ZigBee无线传感网络与GPRS网络,设计开发了基于CC2530和MSP430的节水灌溉控制系统。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、基站、监控中心4部分组成,能实时监测土壤含水率变化。系统利用土壤水分传感器测量土壤含水率参数,对比预设的含水率上下限,判断是否需要灌溉及何时停止灌溉。初步测试证明,该系统运行稳定可靠,能够准确获取土壤含水率信息,并进行节水灌溉控制。和传统灌溉方式相比,自动灌溉实现了智能化、自动化、精确化的灌溉控制,节约了水资源,有效地提高了生产率。In order to save the irrigation water and improve the use efficiency of water resources, computer technology and automanon control technology are applied in the irrigation system. Combined with ZigBee wireless sensor network and GPRS network, the water -saving irrigation control system based on CC2530 and MSP430 is developed. The system takes the single chip processor as the control core, consists of four parts, namely the wireless sensor node, wireless router node, base station and the monitoring center, can monitors real-time soil moisture content. The system measures soil water content by using soil moisture sensor and decides whether it is necessary to irrigate and when to stop irrigate through the contrast with the bound value the water content. The test result shows that the system operation is stable and reliable, can get accurate information of soil water content and conduct water-saving irrigation control. Comparing with the traditional irrigation mode, automatic irrigation realizes the intelligence, automation, precision, saves water resource of irrigation control and effectively improves the productivity.
