Design And Implementation Of Intelligent Large-Scale Garage Search System

The rapid development of China's economy has resulted in an increase in the consumption level of the ordinary people.Coupled with the large population in China,more and more families have entered the automobile era.The increase in the number of motor vehicles and the poor management of existing parking spaces in parking lots have led to parking-related problem.The urgent need for parking services for vehicle users is not met.Although parking lots have been expanded to increase parking spaces,users need to quickly find the location of these parking lots and quickly and blindly reach them.At the same time,there are too many large parking spaces.How to quickly find the parking position of the car in the indoor parking lot is also a very important issue.Therefore,there is a need for a system solution for realizing safe,intelligent,efficient,and reliable system management for a large parking lot,which can be used for searching for guidance in parking lots,parking and picking up vehicles,convenient payment of parking fees,and rational management of parking facilities.Comparing with many indoor positioning technologies,WiFi positioning has the characteristics of strong signal,fast propagation,good network stability and strong anti-interference force.The biggest advantage of this indoor positioning is that it does not need to add dedicated hardware for positioning measurement.The system provides reliable positioning.Through the analysis of the development status of intelligent parking lots in recent years,this paper designed the deployment scheme of WiFi AP sources,and used RSSI position fingerprinting algorithm to locate users indoor,and combined the Android operating system to design and develop a large-scale garage search system.Completion of user management,parking navigation,reverse direction picking,online payment,security alerts and other functions.This article through the understanding of the existing parking system,based on the analysis of the needs of the system framework design,and database and table structure design,use of SOA software architecture,in the client side design WiFi positioning module,HTTP protocol communication module and introduced The design and development process of the client's various functional modules,along with the key parts of the source code,was finally tested on the main functional modules of the car-finding system developed in this paper,and some of the operational effects were demonstrated and analyzed.Through the research on indoor positioning,the user is guided in the direction,the user's time is reduced in operation,and the utilization rate of the parking space is increased.At the same time,the safety management of the user's vehicle is involved in the scheme,and the efficiency of the parking lot manager is convenient in management.
