山东科技大学泰山科技学院本科毕业设计论文题目：基于 PLC 的温室大棚控制系统设计系部名称：机电工程系班级名称：电气工程及其自动化学生姓名：学 号：指导老师： 完成日期:2024 年 6 月 6 日摘要温室大棚是用来栽培农作物的设施，它能改变农作物的生长环境,使其能够外界的四季变化和恶劣气候，为农作物的生长制造适宜的条件。温室大棚作为高效农业的重要组成部分,已经成为我们讨论的方向。如何利用科学技术控制温室内的各种环境因子，已成为我国温室大棚行业讨论的重要课题之一。本论文主要介绍了基于 PLC 控制的温室大棚系统设计方案，该讨论中将采纳温度传感器、CO ２浓度传感器、光照传感器对温室大棚中各项指标进行检测，将测量值送入 PLC 中，在 PLC 中将其与设定值进行比较,再发出相应的指令驱动外围设备来调控温室大棚内的环境参数,从而实现了温室大棚的自动化、智能化控制.在此基础上,实现监测、数据记录、数据输出显示等功能，实现了控制系统优良的人机界面，为温室大棚的讨论提供新的方向。关键词：温室大棚；可编程控制器（PLC）；传感器;控制；ABSTRACTGreenhouses are used for growing plants in a range of facilities ， it can change the crop growing environment ， enabling it to the outside of four seasons and harsh climate, creating suitable conditions for crop growth. Greenhouses as important component of agriculture, has become our research directions 。 How to use science and technology to control environmental factors within the greenhouse, greenhouse industry has become an important subject of study.Described in this paper， based on Siemens S7—200 series PLC control system design of greenhouseThe research will be used temperature sensor， andCO2 concentration sensor, and light sensor on greenhouse big shed in the the index for detection， will measurement value into PLC in the, in PLC will be its and set value for compared, again issued corresponding of instruction drive peripheral equipment to Regulation greenhouse big shed within of environment parameter ， to ach...
