基于物联网技术和模糊控制的智能节水灌溉系统

An Intelligent Irrigation System Based on Internet of things technology and Fuzzy Control

针对我国农业生产中所存在的土壤肥力流失、水资源浪费等问题,本设计基于物联网技术,并结合无线传感技术,设计了一种智能节水灌溉系统。由监测区域内网络节点采集土壤含水量信息,结合不同作物、不同时期的生长信息,以土壤含水量偏差以及偏差变化率作为输入量,建立模糊控制规则库,并用Simulink对控制系统进行了仿真验证,证明模糊控制策略的有效性。实验分析结果表明,该系统能对影响作物生长的土壤含水率实时监测,并提供正确的决策支持,实现了节水灌溉的目的。

In order to resolve the problems which include loss of soil fertility and waste of water resource in agriculture production, we design an intelligent irrigation system based on internet of things and wireless sensor technology. All of the nodes in Monitoring area collect the information of soil moisture, together with the growth information of different crops in different periods, soil mois- ture content deviation and the rate of change of deviation are taken as input variables of fuzzy controller, and the fuzzy control regular database is established for the fuzzy irrigation control system, using Simulink for simulation to prove the effectiveness of the fuzzy control strategy. The experimental results show that the system can real-time monitoring the soil moisture content of crop growth, and provide the correct decision support, which achieve the goal of water saving irrigation.
