The Design And Implementation Of Air Duality Monitoring System Based On PaaS Platform

With the increasing air pollution in our country,air pollution is threatening people's life and health,so the national air quality monitoring requirements are also increasing,people also hope that through the air quality monitoring system,they can arrange their own travel activities.The weather forecast system has been unable to meet people's demand for air quality,and some Real-time Air Pollution Index website is not user-friendly to provide users with clear air quality status and travel advice.ln this context,this thesis designs and implements an air quality monitoring system based on air pollution website data and user requirements,real-time reporting air quality status and advice on travel.The air quality monitoring system based on the PaaS platform is designed to show the air quality index of a city and the air quality index of the surrounding cities.On this basis,users can subscribe to a city's air quality or share a friend's circle.This thesis achieves cloud computing server platform development through the PaaS platform.The system development uses SSH integrated framework.Struts is responsible for MVC separation as the system's overall infrastructure.Hibernate framework does persistence layer services and the Spring framework is designed for integration of Struts and Hibernate.The system front end uses HTML5 and javascript technology.Front-end interaction uses the Rest interface software architecture ideas.Back-end real-time data is mainly used to crawl Python technology.I am responsible for the system background development and data crawling related to the work in the development process.This thesis first elaborates the background of the development of air quality monitoring system based on PaaS platform and the main work of the thesis,and then introduces and analyzes the platform and front and back main technologies used in this thesis.The functional requirements analysis is carried out according to the demand.Based on the demand analysis,the overall design and detailed design of the system are discussed.The realization of the details of process is discussed in the end of the thesis.
