LANZHOU UNIVERSITY OF TECHNOLOGY毕业设计题 目 节水灌溉智能控制系统设计 学生姓名 赵 胜 学 号 08220301 专业班级 自动化( 3 )班 指导老师 成娟娟 学 院 电信工程学院 答辩日期 2024 。 6 。 12 摘 要节水灌溉智能控制技术的高低代表着农业现代化的进展状况,灌溉系统智能化水平较低是制约我国高效农业进展的主要原因。本文就此问题讨论了单片机控制的节水灌溉系统,该系统对土壤的湿度进行监控,并根据作物对土壤湿度的要求进行适时、适量灌水,其核心是单片机通过采纳PID 算法对土壤湿度的控制部分, 主要对灌溉控制技术及系统的硬件、软件编程各个部分进行了深化的讨论.单片机控制部分采纳AT89C51单片机为核心,主要由土壤湿度传感器,AD转换器,显示电路,输出控制电路,故障报警电路等组成; 软件选用C 语言编程。系统主要具有以下功能: 单片机可根据土壤湿度传感器检测到的土壤湿度,自动控制灌溉系统,并且同时显示出当前土壤的湿度值。该系统灵活性强,易于操作,可靠性高,将会有更宽阔的开发前景。关键词:节水灌溉;湿度传感器;单片机 ;自动控制AbstractThe level of auto-control water—saving irrigation technology reflects the development condition of agriculture modernization . The low automatic level of irrigation system is the main reason that prevented our agriculture's development.As to this condition ,this paper mainly studies the drip water-saving irrigation system that controlled by MCU (Micro—controller Unit) .This system call supervise and control moisture of different soil.It can irrigate to different farm corps with the right amount of water at the well time .Its core is the MCU through the use of the PID algorithm for soil moisture control section . Research work hand been carried Oil to the relationship between soil moisture and water, irrigate control technology, hardware and software program and so on.It adopts the top and bottom form to realize the control function of drip irrigation system .Based onAT89C5lMCU , the bottom hardware...
