PAGE I 摘要 为了能够让一年四季均吃上新鲜且种类繁多的蔬菜，温室大棚应运而生。随着而来是的如何让温室大棚更加智能和现代化，因此，本系统设计了一套可用于对温室大棚温湿度、光照强度和二氧化碳浓度进行实时监测的方案。 该方案采用STM32单片机作为系统的主控芯片，搭配温湿度检测传感器、光照强度检测传感器、二氧化碳检测传感器、WiFi传输模块以及其它外围I/O设备，来实现对温室大棚内环境的监测，并且可在上位机实时对数据进行观看，也可将历史记录导出用于分析为大棚改进提供数值参考，从而让系统更加智能化和现代化。通过对方案的论证后进行了实物制作，最终实现了本系统所设计的基于无线传输的智慧大棚监测系统。 在对实物联合调试过程中，通过模拟不同温湿度、光照强度和二氧化碳浓度的变化，从上位机Web端观察数值的变化并且对历史记录进行导出。经过各模块和整体系统功能的测试可以看出，本系统所设计的智慧大棚系统达到了设计要求。 关键词：智慧大棚；温湿度；光照强度；二氧化碳浓度；WiFi无线传输；Web显示 河南城建学院本科毕业设计（论文） Abstract Abstract In order to be able to eat fresh and varied vegetables throughout the year, greenhouses came into being. What follows is how to make greenhouses more intelligent and modern. Therefore, this article has designed a set of solutions that can be used to monitor temperature and humidity, light intensity and carbon dioxide concentration in greenhouses in real time. This solution uses STM32 single chip microcomputer as the main control chip of the system, with temperature and humidity detection sensors, light intensity detection sensors, carbon dioxide detection sensors, WiFi transmission modules and other peripheral I/O devices to realize the monitoring of the environment in the greenhouse, and can The data can be viewed in real time on the host computer, and the historical records can also be exported for analysis to provide a numerical reference for the improvement of the greenhouse, thereby making the system more intelligent and modern. After demonstrating the scheme, the actual production is carried out, and finally the intelligent greenhouse detection system based on wireless transmission designed in this paper is realized. In the process of joint debugging of the physical objects, by simulating the changes of different temperature and humidity, light intensity and carbon dioxide concentration, the changes of values are observed from the upper computer Web terminal and the historical records are derived. After testing each module and the
