Research On Parking Space Display System In Underground Parking Lot

With the continuous development of the domestic economy in recent years,the progress of urbanization has been accelerating,and the rapid growth of car ownership has caused a very serious parking problem,which has brought great pressure to the traffic.In this paper,we set up a relatively complete and comprehensive parking position usage and display system for the difficulty of finding empty parking spaces in the underground parking lot.At the same time,we added the function of advertising display in the system to find the parking space for the parking users.At the same time of the difficult problems,the functions of the current parking lot are continuously improved and enriched,and the economic benefits are increased.In view of the parking difficulties in the current parking lot,this paper first studies the development of smart parking lots at home and abroad,then studies the ARM11 processor and ASP.NET technology,and understands the wireless transmission technology.On this basis,this paper The underground parking space empty parking space information detection and display system was set up and realized.This paper firstly designs and implements the software and hardware design of the parking space information detection module with the single chip as the core and the parking space cluster with the ARM11 processor as the core.The nRF905 digital radio and RS-485 are used to establish wireless comnunication between the modules.The wireless communication protocol is designed between each module to ensure the reliable transmission of data.The display device uses the universal network advertising machine to display the parking space information,and completes the interface design between the advertising machine and the server.Finally,the ASP.NET technology is used to pass the C#language.The regional parking space information display interface and the dynamie switching and display fiunction with the advertising interface are designed.Through relevant tests,the design has very stable hardware performance,which can realize the collection and transmission of information.The parking space information display interface can obtain the parking space information in the database and realize its dynamic presentation.The advertising interface ean eorrectly display the advertisement and according to The entrance information switches between the two interfaces,meets the design requirements,and provides a good solution for the current problem of parking difficulties and a single parking lot function.
