Developing Of Precision Control And Growth Data Traceability For Greenhouse System

As the foundation of China’s economic development,agriculture is the root of national self-reliance and social stability.In recent years,With the continuous development of agricultural Internet of Things technology,the degree of intelligence of solar greenhouses is getting higher and higher.Embedding intelligent terminal systems into the monitoring of greenhouses has become a trend of future development.Based on China Mobile’s free and open Internet of Things cloud platform OneNET,the paper developed an intelligent monitoring system,using STM32F103 as the main control chip to build a hardware system and complete software design,and making use of OneNET cloud platform to monitor the scene in real time.When logging in to the cloud platform,the end users can view the environmental data in the greenhouse anytime and anywhere,and issue commands to implement remote control.Managers can also scan historical data on the cloud platform by scanning the QR code to implement the function of traceability.The main contents of the paper are as follows:1.According to the environmental factors and functional requirements of the strawberry solar greenhouse,the hardware system based on STM32F103 single-chip microcomputer is designed.2.The ESP8266 module is used to implement the wireless communication between the sensor data and the OneNET cloud platform to realize terminal acquisition and measurement.Remote control of field devices by STM32 receiving commands and relay execution,setting upper and lower thresholds according to plant growth needs to achieve automatic temperature control3.The administrator uses the PC webpage,mobile app or scan QR code to log on to the cloud platform for historical data,device online status,and multiple device management operations,and analyzes the growth of crops based on environmental data to achieve traceability of growth data.4.The intelligent terminal equipment was installed on the greenhouse,and the on-site environmental data and equipment were collected online and controlled.The system has been successfully applied to a greenhouse.The actual application results show that the intelligent system is reasonable in design and practical,meets user needs and has high use value.
