基于MQTT协议的智慧农业大棚测控系统研究

Measurement and Control System for Smart Agricultural Greenhouses Based on MQTT Protocol

针对农业大棚生产管理效率较低,大棚内环境监测和控制自动化低等问题,设计了一个基于消息队列遥测传输(message queue telemetry transmission,MQTT)协议的智慧农业大棚测控系统。该系统采用嵌入式集成模块ESP 8266作为主控,结合环境参数感知器和环境调节器等设备实现对农业大棚内环境的监测和调节。使用WiFi通信和LTE通信结合MQTT协议将智慧大棚测控系统和阿里云物联网平台结合在一起,通过手机APP或PC软件访问阿里云服务器数据库,实现了移动终端对农业大棚实时监测和控制。结果表明:该系统对农业大棚环境监测参数准确,控制实时性高,能够实现农业大棚的远程监测和控制,该研究可为当前智慧农业的发展提供参考依据。

Aiming at the problems of low efficiency of production management and low automation of environmental monitoring and control in greenhouses,an intelligent monitoring and control system for greenhouses based on MQTT(message queue telemetry transmission,MQTT) was designed.The system used the embedded integrated module ESP8266 as the main control,combined with environmental parameter sensor and environmental regulator to realize the monitoring and regulation of the environment in the agricultural greenhouse.It used WiFi communication and LTE communication combined with MQTT protocol to combine the intelligent greenhouse measurement and control system with the Alibaba Cloud Internet of things platform,and access the Alicloud server database through mobile phone APP or PC software,the mobile terminal could monitor and control the agricultural greenhouse in real time.The experimental results showed that the system could realize the remote monitoring and control of the agricultural greenhouses because of its accurate monitoring parameters and high real-time control.This study could provide reference for the development of smart agriculture.
