Research And Implementation Of Intelligent Agricultural Greenhouses Based On Internet Of Things

In recent years, Internet of things becomes a hot research field and has been widespread concerned, which represents the future trend of the network. Internet of things with its highly efficient and reliable transmission of information in modern agriculture also has a wide range of application. Greenhouse climate is one of the important factors affecting the greenhouse economical efficiency, which includes temperature, humidity, light intensity, carbon dioxide concentration, water, etc. These natural factors play a vital role in the growth of crops.The Agriculture of Things technology is the foundation of research and implementation of this system. This paper describes the basic concepts of networking and the Internet of agricultural things, including architecture and some of the techniques applied to this article. The agricultural greenhouse hardware system includes wireless sensor data collect module, gateway, server and client.The design and implementation of wireless sensor nodes is based on ZigBee technology. The data is collected by wireless sensor node through the gateway forwarding to GPRS wireless network, using a combination of wireless and wired intelligent transmitted to the monitoring center for monitoring and decision-making process to achieve remote control.The thesis focuses on exploitation of intelligent monitoring center platform, software development tools using C#language, system interface design using WPF, and backstage using the MySQL database to store information.The algorithm of CHL is based on the Klaman fliter and credibility function. The system is optimized by the algorithm and shows that percetptual data redundancy reduces greatly and data transmission is more accurate, while reducing the energy consumption of sensor nodes is obvious, which is verified through Matlab simulation experiments. Finally, it discusses and creates a system of irrigation model, whose error is small compared to the measurement instrument, which has a good prospect for applications.
