Design And Implementation Of Remote Intelligent Monitoring And Control System For Greenhouse In Agricultural Greenhouse

Agriculture is the basis for the country's development and progress.Through continuous reform and innovation,China's agriculture has ushered in unprecedented opportunities for development.Facilities agriculture can effectively compensate for the defects of the natural environment and improve the efficiency of agricultural production.It is the only way for the transformation of China's agricultural modernization.At present,greenhouses of various types of facilities are continuously popularized,but their level of automation is generally low.With the development of communication technologies,microcontrollers,sensors,control systems and the Internet,the Internet of Things has emerged and can be applied in various industries.The Internet of Things can connect objects with objects.The long-distance intelligent monitoring system for agricultural greenhouses based on the Internet of Things can monitor and control the influence factors of crop growth such as temperature,humidity,CO2 concentration,and soil temperature and humidity in greenhouses.There are many factors affecting the growth of crops and they are related to each other.At the same time,the control of greenhouse degree tends to lag behind,which is a problem that can not be solved by commonly used control methods.With the development of control technology,fuzzy control can be applied to facility agriculture,which can solve this complex problem of multi-variable interconnectedness.In this paper,a remote intelligent monitoring system for greenhouses is designed.The main environmental impact factors are the temperature,humidity,CO2 concentration,and soil temperature and humidity in the greenhouse.The main control equipment is the fans,heaters,and irrigation equipment in the greenhouse.The system is divided into three parts: controlled terminal,network communication,and user terminal.The controlled terminal is the main control and related equipment in the greenhouse.The network communication is realized through GPRS.The user terminal is PC and Android operating system.The system implements remote control.The PC and Android mobile phone APP client sends commands to the web server.The web server issues commands.The remote GPRSreceives the data.the lower-position computer reads the GPRS data and parses it to realize the fan and heater.Water valve and other equipment control.Realized by the microcontroller main control,control panel,relay,power supply and air-opening lower machine system through manual control of fan,heater,irrigation equipment.A fuzzy controller was designed to automatically control fans,heaters,and irrigation equipment based on measured air temperature and humidity,CO2 concentration information,and soil temperature and humidity in the greenhouse,so as to make the environment in the greenhouse reach the most suitable growth environment for crops.
