Design And Implementation Of Parking System Based On Electronic License Plate

With the progress of urbanization and the gradual improvement of people’s taste and quality of life,it is very common for people working in cities to own private cars,parking and searching for cars have become difficult problems in our daily life.At present,to solve this problem,some parking lots adopts the methods of road sign guidance,two-dimensional barcodes(QR code)artificial positioning,manual reverse car searching and so on,others parking lots uses image recognition,ultrasonic detection,WIFI,Zigbee and other technologies to get vehicle park information in the parking lot,and then realize the function of automatic reverse vehicle searching.However,due to the high cost of image recognition technology,the complex positioning of WIFI and Zig Bee,and their positioning data is biased,QR code artificial positioning cannot obtain vehicle information in the parking lot,the operation is cumbersome and other problems,the actual economic benefits and popularity are not high,which cannot effectively improve the efficiency of the whole parking lot industry.In view of this situation,the paper going to design and realize the parking lot system based on electronic license plate.This paper introduces the technical principle and application of the electronic license plate,analyzes the business requirements and solutions of the parking lot,This paper analyzes the functions of the parking lot system from five aspects: entrance,exit and management control,parking space guidance and reverse car search,which provides the basis for the design of the entrance and exit management,parking space guidance and reverse car search.In the design,the parking system management is planned from five processes,including frequently parked vehicles in and out,temporary parking vehicle in and out,parking space guidance,reverse search,payment,and so on,and then the parking system software design,parking space guidance algorithm,database design,hardware design are carried out.In the design process,this paper based on the current mature parking lot in and out management technology,combined with the current promotion of senseless payment and Radio Frequency Identification(RFID)technology for electronic license plate,the license plate reader with trigger mode function is associated with ultrasonic detection technology,which is used to obtain the accurate positioning data of vehicles in the parking lot,and then the improved Dijkstra algorithm is used to confirm the optimal path and realize the function of parking space guidance and automatic reverse search.After the system design is completed,the system is deployed,tested and tested to verify the effect of the design and implementation of the electronic license plate in the car park system.From the test and trial run data,the design of the system meets the expected goal.This paper introduces the electronic license plate,designs and realizes the parking lot system based on the electronic license plate,carried out the system test run,system function and the performance test;overcomes the shortcomings of many kinds of positioning techniques,such as image recognition,artificial QR code and so on.What more,in the entrance and exit management of parking lot,parking space guidance and reverse car search,the goal of efficient management and professional operation is also achieved.
