The Design And Realization Of Campus Service System Based On LBS And Cloud Platform

The rapid development of mobile internet, making the traditional PC business gradually extend to the direction of smart mobile terminal, more and more user requirements on the mobile terminal can be achieved.Function of the traditional campus information service system on the PC is so single that cannot meet the overall demands of students,therefore,combining digital campus services with the life,study and entertainment of students that has the realistic value and the significance.In this paper,I have developed an application of campus service system based on LBS and Cloud platform specific to campus information service and the realistic requirement of students on campus,it can meet comprehensive needs of students by providing efficient, fast digitized service.This system mainly uses Eclipse as the platform and JAVA,XML,HTML,JSON programming languages and also adopts Bmob cloud server and its function such as cloud database and cache in my developing process,meanwhile, I use some advanced technologies such as face recognition of iFLYTEK MSC,voice recognition, voice interaction, Jpush information pushing,ShareSDK one-touch sharing, Baidu LBS development platformjsoup web crawler,Zxing QR code scanning,JSON data parsing,Near Field Communication technology and so on,mainly implements more than 20 functions includes registration and login by face recognition technology,registration and login by voice recognition technology,LBS location acquisition and transmission,collegiate digital library, educational administration system, scanning to find books and share readings,campus card, lost and found,2 d and 3 d map navigation and positioning campus street view, express query, take-out query, huada move online ticketing,swiping card sign by NFC near field communication,the campus information,in part-time center, voice interaction, personalized recommendation engine,chatting with friends based on the location of LBS,campus mutual platform,information pushing and so on.With the explosive growth in varieties of information on the Internet, it adds up many difficulties when people get what they’re interested in. Therefore, the thesis attach importance to personal recommendation algorithm especially to the traditional collaborative filtering algorithm so that the different users are able to keep abreast of the information, what’s more, an improved algorithm design scheme has been put forward, based on the improved algorithm, we go a step further to develop a new personalized recommendation engine which is successfully applied to the present system.The tests in each functional module show that digital campus service system which has all reached the expected requirements and worked stability, it provides a fast and efficient digital information platform that had improved the level of teaching and services, enriched students’ cultural life and strengthened the exchange of information.
