The Intelligent Parking System Based On Cloud Platform

At present,China's urbanization process is speeding up,the city scale is constantly expanding,more and more citizens buy private cars,and the number of planned parking lots inside the city is also increasing.Due to the daily fixed driving range of ordinary drivers,once outside the fixed driving area,drivers still face the problem of difficulty in parking in unfamiliar areas and inconvenient parking,resulting in a large number of hidden parking spaces and illegal parking on the side of the road.Therefore,the key point to solve this phenomenon is to conduct unified management of multiple parking lots in multiple cities including Beijing and Shanghai,and make it convenient for drivers to solve all parking problems on mobile phones.The introduction of "Internet plus" and "made in China 2025" in combination with industry 4.0 means that key industries such as the Internet of things,cloud computing,cloud platform,artificial intelligence,virtual reality,value-added manufacturing and robotics will enter the stage of vigorous development and play an indispensable role in China's economic development in the future.In this context,aiming at the parking lot problems and key points in the above-mentioned big cities and combining with the latest technology development trend,this paper designs a set of intelligent parking management system based on cloud platform that can be applied to multi-city multi-parking lots.The smart parking system designed in this paper includes intelligent parking lot monitoring hardware based on geomagnetic sensors,server interaction protocol for hardware acquisition data upload in the cloud,B / S mode program for multiple parking lot management in multiple cities,and external open access interface C / S end parking lot server real-time analysis program and parking lot server back-end data interface API program.On the server side,Tomcat was used as the setup program of multiple distributed servers,and Haproxy middleware was used for load balancing of multiple servers.Memcached was used as the cache,Postgres was used as the RDBMS,and Mong DB was used as the No SQL for data storage of all parking lots.Through analysis,management,and interface programs running on the server,managers,customers,and developers can easily perform functions such as parking lot management,parking lot use,and secondary parking system development.After outdoor testing and field parking lot test,the intelligent parking system based on cloud platform designed in this paper works normally,which is stable in use,and can meet the design and use requirements.
