Data Visualization Design And Implementation Of PM2.5 Stations Management System

Participatory sensing technology combines intelligent terminals and the Internet to build a wide range of perceptual networks,making it possible to collect data at low cost.Setting up sites and guiding users to upload data is the mormal method of data collection used by most applications.The traditional graph in processing such data often has difficulties in reflecting broad categories of information,which can easily result in incomplete information and even miss information.Data visualization technique is generally used to transform structure or unstructured data into the appropriate charts.The design of data visualization to PM2.5 site management system can improve data expression of management system,which may provides a new way of thinking.In the thesis,the data visualization solution for data display and user interaction of management system is proposed.The data visualization module design based on React framework is completed.The web service system of B/S architecture is established to realize the data management system oriented to PM2.5 Data visualization design,based on the completion of site management through data visualization technology to enrich the management system data display.This thesis firstly introduces the relevant background and research significance of data visualization,confirms the research content and main work of the thesis,and then introduces the related concepts of data visualization and technical routes involved briefly.Then,present a system architecture solution based on RESTful(Representational State Transfer)design style.The functional and non-functional requirements analysis,overall design,detailed design and test scheme based on the system architecture are described in detail.System architecture,data visualization module and its data-providing server-side business logic processing module design and implementation.Data visualization module design includes data flow design and interactive design,business logic processing module includes interface design,business logic design and database storage design.On this basis,the system completed the white-box testing,black-box testing to provide users with reliable data support and data visualization services.Finally,the thesis summarizes the completed work and forecasts its future work.
