基于物联网技术的水稻自动灌溉系统应用研究

摘要

介绍了一种基于物联网技术的水稻自动灌溉系统，用户可以在水稻生长的不同时期，通过 GPRS 模块，利用控制器网关、ZigBee 协调器，发送短信控制命令，设置 ZigBee 终端节点水位的上、下限阈值。节点依据水位传感器检测隔田水位与设定阈值的比较结果，控制节点电磁阀的通断，选择开／关隔田引水口水槽闸门，实现自动灌溉。此外，系统用户能够通过短信远程控制电井的电机启／停，实现水井的自动提水。该系统具有实施简单、功耗低、功能完善、可靠性高等优点，具有较好的推广前景。%The paper introduces an automatic irrigation system of rice based on IoT .User could set values of the water level about terminals of ZigBee through GPRS module , gateway and coordinator with sending control command in different rice growing periods .It controls electromagnetic valve to irrigate automatically basis of results about values from water level sensor compare with the user ’ s setting .In addition ,users could control motor to start or stop for water pumping from well remotely by short message service .The system implement simply with low power dissipation , perfect function ,high relia-bility and so on .It has good prospects for popularization .
