The Design And Realization Of Air Pollution Analysis System Based On Web

Since the21st century, with the continuous progress of human society and rapideconomic development, the industry is highly developed. On one hand it brings a lotof convenience to human beings, on the other hand it also causes a lot of negativeeffects. These negative effects on human beings are not expected to preventunfavorable, resulting in a global environmental crisis. Environmental pollution,especially atmospheric pollution effects human beings most directly, when theconcentration of pollutants in the atmosphere reaches a certain value, it will destroyecosystems and normal human survival, serious harmful to human health. In recentyears, more and more air pollution concerns of ordinary people, how to prevent airpollution and improve air quality is the current problems to be solved.The purpose of this project is to provide a reliable channel of information to getthe air pollution situation by developing an air pollution analysis system for the public.At the same time, the website public the hazards and control measures atmosphericpollution, call for more people to join the ranks of atmospheric protection and create aclean breathing environment. The system is designed based on the Web technology,because the Web uses the Internet to share information and widely spread, a large partof people access to information through the Internet, and the number has a growingtrend.There are three parts in this research. Firstly, it is about the analysis of thedevelopment of domestic and international air pollution and it is found that themainstream systems of each country’s content is hard to understand and difficult tooperate. Secondly, it is to have a research on the relevant theoretical knowledge on airpollution, including air pollution theoretical knowledge, pollution causes pollutionhazards. Correlation analysis theory paves the way for the database design. In selectedaspects of the related art, the language of the various techniques for language studycompared, select the appropriate language of the system and technology. This paperchoose B/S network model, MVC design pattern, Tomcat server, MySQL database,Java language, ExtJS language for this study after comparing with others from eachfields. Finally, it is to make a design for the Web System including the design ofdatabase and front page. This paper used Servlet, Java bean, db helper, ExtJS toachieve the target system. In case there is no request, the system remains initializedstate. When a user makes a request, the front desk ext Ajax request background Servlet,Servlet based on user requests call db appropriate helper module, db helper throughSQL queries to obtain data from the database, and then return to the Javabean. TheServlet converts the data returned from the javabean into Json data format, and thenrespond to the front ext Ajax, ultimately should shoot for a variety of chart data. This paper aims to develop a Web system with clear theme, easy management,content-specific, intuitive, no ads, no plug-ins to serve the public for easy use.The system has been proved that it can run perfectly and reach the expected goalsby achieving the related functions. The publicity of air pollution control and the designof Web system air will provide a certain reference on the similar studies.
