智慧大棚控制系统设计

Smart Greenhouse Control System Design

为实现农业现代化中水资源利用率的提高,节约水资源,以环境因素为研究对象设计一套基于STM32F107微控制器的智慧大棚控制系统。系统采用土壤温湿度传感器、空气温湿度传感器、光照传感器等作为系统的感知层,并通过LoRa模块将采集的数据传送到网关,进而通过4G网将其传送给应用层,应用层通过分析处理,把控制命令传回给下位机并执行相应的操作。经多次测试,该系统可以实现信息采集、数据发送和控制功能且具有功耗低、稳定性好、操作简单等优点,实现了自动灌溉和远程操控的功能,提高了水资源的利用率和灌溉效率。

In order to improve the utilization rate of water resources and save water resources in agricultural modernization,a set of smart greenhouse control system based on STM32F107 microcontroller was designed with environmental factors as the research object.The system uses soil temperature and humidity sensors,air temperature and humidity sensors,light sensors and so on as the sensing layer of the system,and transmits the data to the gateway through LoRa module,and then transmits them to the application layer through 4G network,and through analysis and processing,transmits the control command to the lower computer and performs corresponding operations.After many tests,the system can realize the functions of information collection,data transmission and control,and has the advantages of low power consumption,good stability,simple operation and the like,realizes the functions of automatic irrigation and remote control,and improves the utilization rate of water resources and irrigation efficiency.
