摘　　要：设计基于CC2430的无线传感器网络自动控制滴灌系统,实施高效、精确的节水灌溉措施;深入研究系统的硬件构成,软件设计和工作过程,通过田间实验观测通讯质量和滴灌效果;开启时间设定为滴灌后20min能保证数据准确性及实时性;田间实验期间测得土壤湿度最小值24%,最大值为49%,在理想范围内,在作物缺水时,系统能及时灌溉,当湿度达到作物要求上限时则适时停止灌溉,减少不必要的浪费;该系统能够监测植物土壤湿度,环境温度和光照的变化,通过无线网络将传感器信号反馈,结合传感器融合技术对滴灌动作做出精确判断。A new automatic drip irrigation system based on CC2430 wireless network was introduced to implement efficient water--saving irrigation measure. The system＇s hardware structure, software design and work process were discussed by detail. Observe communication quality and drip effect through the field experiment. It will guarantee the data＇s accuracy and real--time that set turn--on time to 20min after drip irrigation. The soil moisture during the experiment of the field was measured as a minimum 24%, a maximum of 49%, ideally within the crop water stress. The system is in time for irrigation, when the humidity reached the upper limit of crop requirements is timely to stop irri- gation, to reduce unnecessary waste. This system can monitor the changes of soil humidity, temperature and light, feedback the sensor sig nals by wireless network with combination of sensor fusion technology to make accurate judgments on the drip action.
