[Abstract]:Greenhouse technology is a kind of highly intensive technology in modern agricultural production. Its core characteristic is to monitor the environmental factors such as greenhouse air temperature and humidity, soil temperature and humidity, CO2 concentration, light intensity and so on. In recent years, China's greenhouse cultivation area is growing rapidly, and people have put forward higher requirements for greenhouse monitoring system. In order to improve the current monitoring system cross-platform poor, data visualization is not high and user interaction is not friendly, and other issues, this paper designed A multi-platform greenhouse monitoring system based on Web3D is presented in this paper. The main research contents are as follows: (1) The function and performance of the current greenhouse monitoring system are analyzed. The Spring-Struts-Hibernate efficient, stable and fast system development framework is selected, and the system function modules and the technical scheme of business implementation are worked out. It is divided into four modules: home page, chart, settings and network. Home page module is mainly responsible for the collection of environmental data and image data; chart module can display and analyze environmental data in a variety of forms; settings module is used for server-side serial port, 3D model positioning and alarm settings; network module is mainly responsible for the network module. Web front-end uses HTML5-JavaScript-CSS3 web page development technology, Tomcat 8 as a Web server, MySQL database to store data, Java 8 as a programming language, combined with SSH development framework to design a Web server. (2) Based on the greenhouse monitoring data (air temperature and humidity, soil temperature and humidity, illumination intensity, CO2 concentration and so on), the meteorological station monitoring data (outdoor temperature and humidity, solar radiation, wind speed and direction) and the chart were added. The ZigBee wireless network composed of CC2530 chip node is used to collect the greenhouse environment data, eKo node collects the weather station environment data, and USB high-definition camera collects the image data. (3) The virtual greenhouse environment is drawn, and the 3D node topology model is constructed. The new generation of web page technology HTML5 WebGL 3D technology is selected to design the topology loading algorithm, load each model through JavaScript script to render the three-dimensional greenhouse monitoring environment. The real-time environmental data monitoring and image monitoring functions are realized. (4) The multi-platform client software is designed. Ionic mixed design mode is adopted. The mobile client software which can cross multiple platforms is designed. The native Android client and the computer desktop client are designed by using Java development environment. The multi-platform client share the same Web server, and the unified business logic processing method realizes different data presentation methods. The client business logic of Ionic mixed design adopts HT entirely. ML5-JavaScript-CSS3 and other technologies are designed. By adding Android and iOS platforms, the client software with fluency and appearance very close to the original can be generated. The above research contents are completed. The function and performance of the multi-platform greenhouse monitoring system based on Web3D are tested. The test results show that the system can perform real-time greenhouse monitoring. Remote data monitoring, 3D topological structure model improves the previous monitoring interactive mode, greenhouse environment data and meteorological station data combined to increase the real-time and reliability of data, video image monitoring to achieve online multi-user data sharing, multi-platform architecture and multi-platform client design ideas to enhance the compatibility of the system The system runs steadily and reliably, the function design meets the requirement, the performance optimization meets the requirement, and can effectively monitor the greenhouse environment, which has certain practical significance.
