Research And Design Of Data Visualization Based On Mobile Collaborative Sensing Platform

With the rapid development of communications, microelectronics, integrated circuits and software technology, the mobile terminal has been rapidly gaining popularity. Smart mobile devices combined its large user with rich computing, sensing and communication capabilities to mobile collaborative sensing technology makes sensing data collection with a wide range of low-cost becomes possible. By moving mobile collaborative sensing technology to collect environmental, traffic and other data, the data has a wide range of applications in environmental protection, public facilities improvement and national health condition enhancement. Through data visualization technique sensing data can be presented in a simple and intuitive way, so we can more easily grasp the changes and the association between different data, which can provide guidance for us to solve related problems.In this thesis, based on the background of mobile collaborative sensing and related technologies of data visualization, a web-side data visualization system based on mobile collaborative sensing platform is designed and implemented. The system is able to visualize the collected sensing date in the web interface based on location, including the display of data POI (Point of Interest) polymerization on the map, as well as the dynamic display of collected location-based data, such as pictures, PM2.5.First, this thesis introduced the mobile collaborative sensing research background and related web-side data visualization techniques briefly; After that the architecture of mobile collaborative sensing platform is designed, on the basis of that the requirement analysis and system design of data visualization system is made; Next, detailed design and implementation of each sub-module are depicted in detail, including web front-end data visualization module and server-side data processing module; Then the whole system functional tests show visualization system to achieve the desired design goals; and finally, the summary the whole work, the inadequate and the future work of this thesis are briefly described, and the summary all of the work and achievements of author during the graduate students are given.
