Research And Development Of Indoor Parking Management System

With the development and progress of science and technology,the car ownership of urban residents have reached an unprecedented level,but the existing parking resources can not meet the growing demand for parking.How to improve the utilization of existing parking resources in parking lots to ease the contradiction between the supply and demand of urban parking space has become a crucial problem that needs to be solved urgently.Applying the two-dimensional code to marking the indoor position,this thesis studies the technologies of parking management system.Firstly,the composition of the elements within a parking lot is analyzed to design a model of double-layer network combining the pavement and carriageway.Secondly,based on the mentioned model,the method to correlate the spatial information with the existing two-dimensional code together with its coding rule is set by studying the topological correlating method and the layout of the code.Then,a path guidance algorithm based on the above network model is studied,combining with the Dijkstra Shortest Path Algorithm.Finally and the most importantly,a new management system of indoor parking lots is developed applying the above technical study.Using WiFi and mobile devices,through the data exchange between the mobile client and the sever,this system achieves the administrators' management and coordination of the parking resources,provides optimal path guidance for the clients and so on.The system includes the mobile client and the server-side.It designs and implements the modules of 1)the registration and log-in for users,2)Baidu map guidance,3)verification and timing at the entrance,4)parking distribution,5)guidance of parking/tracking the vehicles,6)individual parking information in the mobile end;it designs and implements the functions of 1)data query and management,2)administrator log-in and registration,3)two-dimensional code generation and other functions in the server-side.At the same time,the parking information management database is set up,the dynamic data updating of the server is realized,and the Socket communication specification is designed based on the TCP/IP protocol,and the communication content is transmitted and analyzed.The indoor parking lot management system developed in this thesis is in line with the modern way of life with no need of any other vehicle equipment,which has certain practical and promotional value.It can be widely applied in places with large parking lots through further system development and improvement.
