摘要
针对传统灌溉系统存在的人工操作繁琐、水资源浪费严重及自动化程度低等问题,本文设计并实现了一种基于单片机的节能型智能灌溉控制器。系统以STC89C52单片机为核心控制单元,通过土壤湿度、温度和光照等多传感器实时采集田间环境参数,并结合作物需水模型与阈值控制算法,实现对电磁阀、水泵等执行机构的自动启停控制。为提高系统能效,控制器采用分时供电与休眠唤醒机制,结合太阳能供电模块与蓄电池储能系统,具有结构简单、成本低廉、智能化程度高等优点,可为农业节水灌溉及智能农田管理提供可靠的技术支撑。
To address the problems of cumbersome manual operation,serious water waste,and low automation in traditional irrigation systems,this paper designs and implements an energy-saving intelligent irrigation controller based on a microcontroller.The system uses the STC89C52 microcontroller as the core control unit and collects real-time field environmental parameters such as soil moisture,temperature,and light intensity through multiple sensors.Combined with the crop water demand model and a threshold control algorithm,the system realizes automatic start-stop control of actuators such as solenoid valves and water pumps.To improve energy efficiency,the controller adopts a time-sharing power supply and sleep-wake mechanism,integrated with a solar power module and battery storage system.The system features a simple structure,low cost,and high level of intelligence,providing reliable technical support for agricultural water-saving irrigation and intelligent farmland management.
