| 摘 要： | 为解决目前丘陵地区果树灌溉技术中存在的过度灌溉、浪费水资源等问题,以实现丘陵果园节水灌溉,结合无线传感器网络技术,设计开发了一种基于无线传感器网络的丘陵果园灌溉控制系统.系统以ATmega128L单片机为控制核心,由上位机、汇聚节点、无线传感器节点、土壤水分传感器和电磁阀等组成,其中土壤水分传感器和电磁阀连接到无线传感器节点上,汇聚节点与传感器节点之间数据采用无线方式进行传输,汇聚节点通过RS-232串口线与上位机相连.系统能实时监测葡萄土壤含水率的变化,根据土壤含水率来判断葡萄是否缺水,并发出灌溉指令实施对葡萄精确灌溉,系统实现了葡萄园灌溉的自动化控制.通过试验,选定25 cm深度的土壤含水率为灌溉启动监测量,启动灌溉的监测阈值设定为26.8%;选定50 cm深度的土壤含水率为灌溉停止监测量,系统停止灌溉的监测阈值为45.5%.试验表明：系统可以达到精确灌溉要求,结合葡萄的生存阈值可以实现节水灌溉.
