日光温室环境变量远程监测及自动调控系统研究
Remote Monitoring and Automatic Regulation System for Solar Greenhouse Environment
近年来,中国日光温室面积持续扩大,截至2024年,全国设施农业总面积已突破400万hm2。为提升日光温室农作物的产量及质量,并便于工作人员实时监测和调控日光温室环境,本研究设计了一套基于PLC的日光温室远程监测及自动调控系统。该系统结合了PLC控制技术、LoRa无线扩频技术和移动物联网技术。利用LoRa无线传输技术搭建了传感器数据无线传输网络,通过编写触摸屏组态程序和PLC手自一体程序,实现了日光温室空气温度、空气湿度、光照强度、二氧化碳浓度、土壤水分、土壤温度6类重要环境变量的实时监测,并能根据实时环境数据自动控制日光温室执行设备的启停。此外,利用4G DTU无线通信模块和云服务器,系统实现了数据的远程实时监测与导出,日光温室执行设备的远程控制,以及上位机和下位机的远程无线通信。
In recent years, the area of solar greenhouses in China has continued to expand. As of 2024, the total area of facility agriculture across the country has exceeded 4 million hectares. To increase the yield and quality of crops in solar greenhouses and facilitate real-time monitoring and regulation of the greenhouse environment by staff, this study designed a remote monitoring and automatic control system for solar greenhouses based on PLC technology. This system combines the PLC control technology, LoRa wireless spread spectrum technology, and mobile Internet of Things technology. It built a wireless sensor data transmission network using the LoRa wireless transmission technology. By writing a touch screen configuration program and a PLC integrated program, real-time monitoring of six important environmental variables, including the air temperature, air humidity, light intensity, carbon dioxide concentration, soil moisture, and soil temperature, was achieved in a solar greenhouse. The system could also automatically control the start and stop of the equipment in the solar greenhouse based on real-time environmental data. In addition, using 4G DTU wireless communication modules and cloud servers, the system enabled remote real-time monitoring and data export, remote control of the execution equipment in the solar greenhouse, and remote wireless communication between the upper and the lower computers.
