摘　　要：在水稻生长的不同时期合理控水灌溉,不但节约水资源,而且还可以提高稻田的产量。为此,设计了基于LPC2103的稻田自动灌溉系统,通过超声波测距模块测量稻田水位高度,使用SHT75湿度传感器检测稻田的湿度,并根据水深和湿度数据决定电机是否工作。软件采用uC/OS-Ⅱ操作系统进行任务管理,实现GPS数据获取、GPRS发送信息、湿度检测以及控制功能。对样机的测试结果表明,设计达到了预期的目的。In the paddy rice different grow period,reasonable irrigation not only economize the water resource,but also can also raise the yield of the paddy field.According to this,the paper designs the paddy field auto irrigation system based on the LPC2103.The ultrasonic waves is used to measure the paddy field water level height.SHT75 sensor is used to detect humidity signal.The water level and humidity decide the pump of water when begin to work.uC/OS-Ⅱ operation system is used to manage multi-task software.Four tasks which include initial task,GPS data deceive,GPRS data transmit and humidity supervisory control are used in order to realize the function of the system.Every task＇s relation method is gave.Test machine is made,which realize all function which are required by the system.
