Research On Key Technology Of Parking Lot Based On Radio Frequency Identification

With the increasing development of economy and the enhancement of national integrated power, more and more families own the vehicles. To face the encroaching of the time of vehicle, people have been stricter whit the smart parking lot. Therefore, the programme of the city has view the parking lots as the important point. The large new building should be allocated with certain scale of underground parking lot in Guangzhou. The number of the vehicles runs with each passing day, which has brought the problems of the parking and safe. For this reason, people have paid much attention about these problems.Aimed at the situation, this paper concentrates efforts on studying a new management of the smart parking lot, based on the technology of RFID (Radio Frequency identification) , which can take place of the traditional ways of collecting fees by hand. This paper has introduced the basic theory and applies of RFID. Linking with the purpose of the design and the superiority of the RFID, we try to achieve the convenient fast safety pay system without ceasing vehicle.This design is based on the RFID system , which communicates with the tags on the frequency of 915MHz. The reader controlled by the single chip of 89C51 is able to identify automatically the number and style of the vehicles and charge with the long-distance electric tags by programmed operating orders. Moreover, the design includes the backstagecomputer controK the comparison of images^ the check of the detector data refresh in the database. By the way ,the new style of smart parking lot has comBINed wonderfully the ideas of the life-, the technology of information^ the technology of computer and so on together. The management system is simple^ convenient advanced and quite humanized.The main contains of this thesis is anti-collision algorithm of RFID system, the communication between the reader and the tags, the design of the antenna and the program design of the management system of parking lot. To sum up, the research and result of this thesis should be valued in actual field.
