Research On Intelligent Monitoring System Of Greenhouse Fruit And Vegetable Based On IOT

Intelligent greenhouse technology can create a suitable environment for crop growthand eliminate the environmental factors such as temperature,humidity,carbon dioxide concentration and so on.China is a large agricultural country and agricultural production security necessary to our daily life.The agricultural industryis an important pillar industry for the large population and it is supporting the steady development of our economy.China's per capita arable land area is less to rely on increasing the total cropland area to improve the total yield it is not feasible,the intelligent greenhouse can effectively improve crop yield per mu.This paper studies the related technology of the Internet of things in agricultureand selects the most suitable technology to monitor the system.According to the design of the three layerthis paper from the data acquisition module and the wireless communication module and the application layer terminal module are analyzed and designed.This paper uses the ZigBee wireless sensor network technology to solve the routing problem based on intelligent greenhouse environmental parameters monitoring and realize the wireless timing acquisition function of environmental parameters of intelligent greenhouse,at the same time,the data acquisition module is designed to plug and play GPRS.The collected data will be transmitted to the server and the server can receive the instruction of reverse control monitoring parameters.The current control method of intelligent greenhouse are need to establish accurate mathematical model in order to create the most suitable environment for the growth of fruits and vegetables,but the nonlinear variation of environmental parameters in greenhouse which affected the accuracy of the model.Design a kind of PID control and fuzzy control method are combined to control effect of fruit and vegetable growth light intensity and temperature and humidity parameters model according to the greenhouse effect of complex environmental parameters of fruit and vegetable growth.In this paper,the fuzzy PID control system with compensation is designed by analyzing the coupling relationship between the two parameters of temperature and humidity.Fruit and vegetable greenhouse intelligent monitoring system based on Internet of things it have perfect functionwith "real-time,stability,applicability,expandabilitylow cost and easy operation of the design principlesafter installation and debugging and it can achieve efficient management of greenhouse.
