Design And Implementation Of High-speed Vehicle Identification System Based On RFID

What this thesis discussed is one of the projects that our country has emhasised all theseyears. The RFID system has wide prospect of market，which has low cost, convenientoperation, high reliability and other advantages using in no parking charge application.In this article, high-speed vehicle identification system based on nRF24L01RFtransceiver chips was completed,which use the CC2530F256chips produced by TI,accordingto2.4-2.5GHz ISM requency band active electronic tag.In the design of reader,this paper usedthe same two reader,realizing the communication between readers and the computer. Whenthe tag vehicle in turn after two readers, readers will timely recognize electronic taginformation, and upload the information to the computer.Firstly,basing on the principle of functional modularity and the researching of2.4GHznRF24L01and SoC CC2530,we designed the active RFID tag and RFID reader,solving theproblem of the driver writing, RF transfer,data encoding and encryption,and low-power bysoftware.Sencondly, through researching CC2530and RFID application,we encoded theprogranm drive to accomplish the function of calibrating information,communicating with RFcontrol unit for RFID tag identification,and realized the accurate reading from readers to tag.Finally,it proved that the RFID readers can read and write datas of RFID tags bydebugging the equipment,and transfer the informations to the monitor computer byRS232.Further tests show the system can work reliably,perform better,and with low cost,besides,it also can be used in identification for the high-speed vehicle.
