基于EPC标准的RFID读写器研究实现.pdf

Abstract Abstract UHF RFID(Radio Frequency Identification)is one of themost advanced technologies presently,and hasbeen applied inmany fieldsdue to itsadvantages,such as long identification distance,high recognition ratio,rapid operation,excellent anti-interferenceability,relatively long lifeand theability to rate non-metal ,because oftheshorthistory ofdomestic research on UHF RFID。 alsowith petitive self-owned keytechnique on readerhasn't been setup,consequently UHF RFID readerhas e ahotresearchpoint indomestic. As amain protocol for RFID in UHF band,EPC Class一1Generation一2(EPC Gen2)has many advantages,such patibility ofglobal frequency spectrum,protection ofprivate information,rapid identification andair interface fistly introduces thetheory of RFID system and the content of EPC protocol ,it realizes aRFID reader which works on ,the resultofrealization and some improvments ofdesign aregiven. Reader system includes two isthe reader and and theother reader part is in charge ofrealizing EPC protocol posed of main function,encoding anddecoding,CRC, anti-collisionand SO rails on asingle-chip processor,and thebaseband rate can host runs on theplatform ofembedded system,which made up of arm-core processor and Linux operating system,and withQt wecaneasilydevelop thesoftware forRFID graphic operation. This paper also makes adiscussion on anti-collisionalgorithm,which is akey problem inRFID simulating Q algorithm withMatlab,we get agroup ofoptimized parameters,which mmakes readerworks atthehi曲est anti- thismethod gets tobe used intheimplementation.
