基于PLC控制的智能节水灌溉系统设计

Design of an Intelligent Water-saving Irrigation System Based on PLC Control

设计一种智能节水灌溉系统,并对其进行性能评估。首先,分析现有灌溉系统,确定设计目标和要求。其次,使用可编程逻辑控制器(Programmable Logic Controller,PLC)作为系统的控制中心,采用传感器网络实时监测土壤湿度、气温和降水量等参数,实现自动化的灌溉控制。最后,采用模糊控制算法调整灌溉流量,以满足不同作物的生长需求。实践结果表明,与传统定时灌溉系统相比,基于PLC控制的智能节水灌溉系统能够显著减少水资源的浪费,提高灌溉效率,并且能够根据环境条件和作物需求进行智能化的灌溉调整。

An intelligent water-saving irrigation system is designed and its performance is evaluated.First,by analyzing the existing irrigation system,the design objectives and requirements are determined.Secondly,the Programmable Logic Controller(PLC)is used as the control center of the system,and the sensor network is used to monitor parameters such as soil moisture,temperature and rainfall in real time to achieve automatic irrigation control.Finally,the fuzzy control algorithm is used to adjust the irrigation flow to meet the growth needs of dfferent crops.The practice results show that compared with the traditional timing irrigation system,the intelligent water-saving irrigation system based on PLC control can significantly reduce the waste of water resources,improve the irrigation efficiency,and make intelligent irrigation adjustment according to environmental conditions and crop needs.
