Design Of Shared Parking System And Development Of The Service-side

With the rapid development of economic and the surge of vehicle's possessive quantity,parking problem is coming out.According to the latest survey,parking lots of residential land and others are strongly complementary mutually in the time.It brings an opportunity for relieve the acute problem of parking.Firstly,the shared parking system which is based on cloud platform and managed by the property is designed through the study of theories about shared parking.This system solves the problem of "Isolated Information Islands"in parking effectively,and improves the efficiency of parking spaces.Secondly,according to the demand analysis of shared parking system,system function is decomposed into seven modules:login with registration,input parking information,release parking lots,rent parking lots,vehicles search,payments and history records.The MySQL database management system is selected to complete the development of database with the database concept design and the logic design.Java development platform,MVC pattern together with SSM framework are choosed to develop the service side of this system.Thirdly,the key problems of reverse vehicle search and corresponding solutions are proposed.A fingerprint localization scheme based on BLE technology is proposed to slove indoor location.Gauss filter and neighborhood mean filter are used to ensure the accuracy of fingerprints in the offline training.Kalman filter toghther with weighted KNN algorithm are used to ensure real-time performance in the online positioning.A routh planning scheme based on beeline optimizing Dijkstra algorithm is proposed to solve indoor path planning.The dijkstra algorithm and the straight line optimization dijkstra are studied by the modeling of actual parking lots in this paper.Finally,test cases for function modules are designed to test the function of system's service side.These tests shows the whole system function is realized.
