Design Of Intelligent Parking Management System Based On RFID Technology

With the continuous improvement of China's civilian car ownership,in some big cities such as Beijing,Shanghai and Guangzhou,the parking problem has already rose from the personal problem to the social problem.For the lack of the urban land resource,the number of parking construction is not enough for people's actual requirement,especially at the crowded area such as supermarkets,schools and hospitals.Additional the traditional parking management doesn't focus on the real time status of parking,and the management is artificial and low efficiency.It makes greatly reduce the utilization ratio of parking spaces,and increases the parking difficulty for people.Intelligent parking management system can make the administrators of parking fields recognize the real time states of parking spaces,and then instruct the car owners to park correctly.Through the system,it can improve the quality of packing management,reduce the parking time to some extent,improve the utilization ratio of parking spaces and the security management of cars.This article mainly analyzed with the main car sensing schemes at present.Combined with the actual situation of the engineering project,the microwave sensing scheme based on Radio Frequency Identification(RFID)was decided to choose for the core content of the article.For the control of investment of hardware in the actual engineering project,it improved the car sensing scheme by building the secondary collaborative awareness model and N level cooperative awareness model.In addition,for the possible problem of signal interference,the scheme added the anti collision algorithm to improve the accuracy of the model.By the test,the accuracy of the car sensing scheme which based on this technology was very high.So it could build the intelligent parking management system by this scheme.Combining with the example of the project of intelligent parking management system for China Mobile Shanghai branch,this article used RFID technology to design a set of intelligent parking management system,which included seven functions of parking spaces sensing,license plates recognition,automatic access,parking guidance,reverse searching cars,network transmission and central management.It basically realized the design requirements of the project,improved the management level of the park.Through the improvement of the utilization ratio of parking spaces,effectively alleviate the parking problem in this company.
