Research And Implementation Of Flowershed Temperature Control System Based On OneNET Cloud Platform

In northeast China,the winter temperature is relatively low,generally between-15 ℃-25 ℃,such continuous low temperature is not conducive to plant growth,people generally use greenhouses for plant cultivation,flowers are the same.But even under the premise of using a greenhouse,the temperature is still very low at night or in cold weather in the northeast region.At this time,artificial heating and heating in the flower shed are needed to ensure the growth conditions of the flowers.The traditional heating method consumes manpower,and generally raises the temperature in the flower shed by methods such as firing and charcoal burning.This method has the following disadvantages: 1.Low energy utilization rate.2.The temperature is not easy to control.3.Environmental pollution.Therefore,it is necessary to design a temperature control system with high energy efficiency,free control of the heating state and low environmental pollution.Based on the above requirements and background,this article applies the Internet of Things temperature control system to the greenhouse greenhouse,so that producers can observe the environmental data in the greenhouse in real time,and can remotely control the equipment,so that the plants can obtain the most favorable growth conditions.This system uses the STM32F103C8T6 chip as the control module,and the core temperature control function is based on the adaptive fuzzy PID control algorithm.The system collects the ambient temperature through the HTU21 D temperature sensor and detects the water pipe pressure through the pressure sensor.The ESP8266 module of the hardware device sends data to the OneNET cloud platform through the EDP protocol and uploads the collected data to the cloud platform in real time.The APP connects to the OneNET Internet of Things platform for data interaction.The APP client displays various data such as water pressure,voltage,and temperature in real time,and realizes remote control of the hardware terminal to ensure the safe and stable operation of the system.OneNET cloud platform also has a data storage function,which can analyze and organize the data inorder to observe and record the environmental data of each stage of plant growth.Through the overall test of the system,the results show that the system can meet the functional design requirements,the temperature control function is normal,the data transmission is smooth,and the remote control function can be realized.Compared with the traditional flower shed heating and heating method,it has higher energy utilization efficiency,simple and convenient operation,lower energy consumption,and higher system reliability.This system has achieved the expected results.
