Research And Development Of Intelligent Greenhouse Monitoring System For Strawberry Greenhouse

The traditional planting of strawberry greenhouse usually uses the artificial collection of environmental parameters,and the fruit growers rely on their own experience to manually adjust the greenhouse environmental parameters.The artificial collection method not only has low work efficiency,but also can not guarantee the real time of the data,which directly affects the yield and quality of strawberry,which greatly restricts the development of greenhouse technology in China.In recent years,with the rapid development of network communication technology,agricultural information in China has been promoted in an allround way.The technology of Internet of things has been widely used in agriculture.It has realized the comprehensive perception,reliable transmission and intelligent processing of agricultural information data,which made the greenhouse of remote intelligent control system become a reality.However,compared with the developed countries,there are still a certain gap in the greenhouse intelligent monitoring system in China.On the one hand,the high cost of the greenhouse monitoring system is high,which leads to the imperfect supporting facilities of the system;on the other hand,the system operation is tedious,which restricts the industrialization of the greenhouse monitoring system.In view of the above problems,this paper introduces the Internet of things technology and fuzzy PID control into the environmental monitoring system of the strawberry greenhouse,and realizes the intelligent monitoring of the greenhouse in the strawberry from the aspects of low cost,precision control and easy operation.The main contributions of this paper are as follows:(1)According to the system design requirements,the overall design of the system is carried out.According to the environmental characteristics of the strawberry greenhouse,the environmental monitoring system of the greenhouse greenhouse is divided into three levels of the IOT perception layer,the Internet of things network layer and the Internet of things application layer,and the relevant theories and customs of the three layer architecture of the Internet of things are carried out respectively.The key technology is introduced,and the hardware architecture is built.According to the needs of the hardware acquisition system,the software design is carried out.Considering the power consumption of the system,the sleep mode program of sensor nodes is designed.The energy saving effect is obvious,and the energy saving demand of the system is satisfied.(2)In view of the strong coupling,nonlinear and lagging characteristics of greenhouse,this paper applies the fuzzy control algorithm and PID control to the control module of the system,and simulates the whole greenhouse monitoring system as the controlled object on the MATLAB,and compares several other algorithms,and gets more ideal results.Achieve the desired goal.(3)Use C# advanced programming language to develop host computer software,realize the automatic collection of environmental parameters in greenhouse,and save the data in the MySQL database,and can check the environment parameters in real time and carry out intelligent control on the Web page.The greenhouse environmental monitoring system of strawberry greenhouse,through debugging and running in the laboratory and greenhouse environment,fully embodies the stability,reliability,low price and other characteristics of the system.At the same time,it also has a high reference value for the planting of other greenhouse crops.Therefore,this system has high economic and promotion value.
