Study On Display System Of Parking Stall’s Information Collection Of Underground Parking Lot In Business District

With the development of economy and society,China’s car ownership of residents significantly increased,resulting in a serious problem of parking is difficult,difficult to stop in city center and commercial areas.According to the problem of difficult to park and the existing shortcomings of underground parking lot in the commercial area,this paper designs display system of parking stall’s information collection,and aims to solve the problem of searching for empty parking spaces and improve efficiency in the underground parking of business district.Based on the existing problems of the underground parking lot in the commercial area,this paper first analyzes the development status of the underground intelligent parking lot at home and abroad,remote information collection and wireless transmission technology.On this basis,this paper designs a display system of parking stall’s information collection of underground parking lot in business district.The hardware design of this system mainly includes three parts.The first one is the terminal information collector.Each collector uses MCU as the control chip,and connects multiple ultrasonic sensors to collect parking information.The second is the floor repeater,instructing and controlling each information collector to work,at the same time,relaying the information to the server.The third is display controller of the district,which receives information from collectors and outputs the information to the display equipment of the district.Among them,the information collector,the floor repeater and the display controller of the district use nRF905 radio to establish the wireless communication,formulate the communication protocol and realize wireless assembling.At the same time,C#technology is used to design dynamic display software of the the server and the district.The Socket communication protocol is done between the server display software and the floor repeater based on the TCP transmission protocol.The area display software and the controller can communicate with each other through RS-232.These two kinds of display software were implanted into real panorama and partial scene of parking stall’s geographic information respectively,each parking stall displays real-time usage with red and green logo.Meantime,the embedded software is designed to control the execution function of each hardware unit.The physical test shows that the hardware design of the system is stable and can collect the parking information in real time and send.The two kinds of host computer dynamic display software can receive the data stably and dynamically display the use situation of the parking stall.This system improves the efficiency of searching for parking spaces,and meets the design goals and requirements,especially has a higher application value for solving the outstanding problems in the underground parking of business district.
