摘  要：
采用单片机、无线传感器网络(Wireless Sensor Networks)、GSM无线通讯以及变量控制等技术,设计了一套精确灌溉的闭环远程监控系统。系统由上位监控计算机、灌溉监测控制器、STC89C52为核心的无线传感器网络、GSM无线通讯模块和阀门组成。远程监控中心计算机采用组态软件实现数据管理、人机界面来达到用户监控的目的。实验结果表明,数据采样间隔设定为30 min,选用4组WSN节点,监测得到深度为25 cm的土壤温度、湿度和土壤含水量,1号节点分别为25.60、0.65、0.85,2号节点分别为25.00、0.60、0.65,3号节点分别为25.30、0.70、0.90,4号节点分别为24.80、0.58、0.74,1号和3号节点电磁阀指示灯显示绿色未报警,2号和4号节点电磁阀指示灯红色触发报警需及时打开阀门进行灌溉。系统在线自动监控作物需水量以自动调整阀门的开关,达到按需灌水的目的,与人工手动灌溉相比,智能灌溉可节水约20%,实现了节水灌溉的目的。

摘  要：
A closed-loop remote monitoring system for precision irrigation is designed by using microcontroller,wireless sensor networks(WSN),GSM wireless communication and the variable control technology.The system consists of monitor computer,irrigation monitor controller,WSN based on STC89C52,GSM wireless communication module and valves.Remote monitoring center computer uses configuration software for data management and HMI that achieve the purpose of the user control.The results of the experiment,in which the data sampling interval is set for 30 min and 4 groups WSN nodes are chosen,show that the system could get soil temperature,humidity and soil water content in 25cm depth.Among them,node 1 are 25.60 0.65,0.85,node 2 are 0.60,0.65 25.0,node 3 are 25.30,0.70,0.90,node 4 are 24.80,0.58,0.74,respectively.Furthermore,electromagnetic valve indicator of node 1 and 3 show green,no alarming,but electromagnetic valve indicator light of 2 and 4 node show red and alarming is triggered,which indicates that the system should open immediately valve for irrigation.The system can monitor crop water requirement and adjust automatically the valve switches.Comparing with manual irrigation,intelligent irrigation can save water about 20% and achieve the purpose of water-saving irrigation.
