摘　　要：【目的】农业用水浪费较严重,灌溉水利用系数较低,很多地区存在水资源匮乏的问题,所以,走节水节能型农业发展之路是必然趋势。【方法】建立以MSP430F147为核心的单片机节能灌溉系统的控制模型,该系统平时处于休眠状态,固定周期进入活动模式,耗能低,从而实现系统的低功耗。【结果】该系统通过测量土壤介电常数确定土壤湿度,然后根据土壤湿度值来确定作物的灌溉用水量,单片机定时控制灌水量,从而达到节水节能的目的。【结论】该系统节水节能,同时通信方式采用无线通信方式,传输距离远,安装方便并减少了通信线路安装的成本,符合未来通信的发展方向。[ Objective ] China ＇s agricultural water is severely wasted with lower utilization coefficient of irrigation water, and water resource is lacked in may places across the country, so taking the road of water - saving and energy - saving agricultural development is an inevitable trend. [ Method ] In this paper, an energy -saving irrigation control system model based on the MSP430F147 microcontroller is built up as the core. This system usually sleeps at peacetime, and goes into active mode in fixed cyclic period with a low -power consumption. [ Result] This system can determine soil moisture by measuring the soil dielectric constant and determine the amount of irrigation according to soil moisture, thus achieving the purpose of saving water. [Conclusion] This system uses wireless communication, transmission distance, and easy installation and reduces the cost of installed communication lines, meets the future direction of develooment communication.
