Research And Design Of Intelligent Greenhouse System

With the rapid development of science and technology and economy in the 21 st century,many computer science technologies have also been used in the agricultural field.Intelligent greenhouse greenhouse automation control technology plays a vital role in agricultural cultivation.Many advanced technologies were developed in the end of the last century.Western countries have effectively combined smart greenhouse monitoring technology and greenhouse control technology to monitor the growth of crops in greenhouses,to maintain the optimal growth environment for crops,and ultimately to achieve high crop yieldsThe greenhouse greenhouse system designed in this project can detect the light intensity in the greenhouse,the temperature and humidity of the air,and the carbon dioxide concentration.The MCU main control unit analyzes and processes the collected data through the corresponding sensors,and then passes the 3G communication module.It is pushed to the Android phone for effective display.The intelligent greenhouse manager can monitor the environment inside the greenhouse through a mobile phone at any location in the network,and use the designed APP to control the shading equipment and ventilation equipment in the greenhouse in real time to achieve the purpose of remote intelligent control.This paper applies the embedded architecture to the intelligent greenhouse control system.The MCU main controller selects the STM32F103 development board as the main control unit,DHT11 components are used as the temperature and humidity sensors,the light intensity sensor is BH1750 FVI,the carbon dioxide is the T6004 sensor,and the main control circuit For relay-driven motor control,the 3G wireless communication module is connected to the Android platform through wireless communication technology.The design of the hardware circuit is highly integrated,and the structure is simple to facilitate later testing and maintenance.Software design using STM32 microcontroller into the μClinux system as the operating system,to achieve environmental control and parameter acquisition and data wireless transmission function,effectively reducing the delay of sending instructions to achieve a fast and efficient control purposes.At the same time,a greenhouse greenhouse data platform was established to display and process various parameter data,and the data was visualized to draw curves,and then the decision-making analysis was conducted on the environmental management of greenhouses in the later period.
