Reasonable irrigation not only provides plant growth must, but also in line with the promotion of water saving irrigation in Chinas national condition. Crop irrigation water quality on the one hand for greater accuracy, higher irrigation uniformity; On the other hand required to ensure water supply reliability and continuity. In practice, two requirements to achieve this alone can not meet the manual, so the intelligent control of irrigation systems came into being. In this paper, the intelligent water-saving irrigation of the ZigBee wireless sensor network is designed. the ZigBee wireless sensor networks, modern mobile communications, Ethernet, three networks combined by the ZigBee wireless sensor networks in real time on soil moisture monitoring, the use of mobile communication networks and optical Ethernet systems and remote monitoring to achieve the information of the staff interaction. The main focuses of the ZigBee wireless network topology design, directed diffusion routing protocol to improve and the underlying data fusion algorithm. Keywords: Smart , Water-saving irrigation , ZigBee 目录 摘 要 III Abstract IV 1 绪论 1 1.1智能节水灌溉的来源 1 1.2智能节水灌溉的意义 1 1.3智能灌溉的国内外发展现状 2 1.3.1 国外的发展现状 2 1.3.2 国内的发展现状 2 1.4课题研究的主要内容 3 2设备方案设计与总体设计 4 2.1设备的方案设计 4 2.2设备的总体设计 5 3硬件设计电路 7 3.1 设计电路图 7 3.2 控制芯片介绍 8 3.3 湿度检测电路 9 3.3.1湿度传感器HS1101简介 9 3.3.2 HS1101优点 10 3.3.3 HS1101与单片机接口设计 10 3.4 温度检测电路 11 3.4.1 温度传感器DS18B20简介 11 3.4.2 DS18B20与单片机的典型接口设计 12 3.4.3 DS18B20使用中应注意事项 13 3.5 报警电路 14 3.6 电源电路 15 3.7 电平转换电路 16 4软件设计电路 17 4.1软件开发环境 17
