Abstract


RFID technology (Radio Frequency Identification, RFID) is a new technologywhich emerged in the1990s and develops very fast in the past years. RFID technologywith high-precision, high fitness, high-speed, high-capacity, long-range, multiple readand write data encryption, etc., there is a wide range of applications in industrialautomation, logistics, transportation, supply chain management and retail sector, thistechnology will become the mainstream of automatic identification in the future.With the extensive application of RFID technology, RFID system to identifyefficiency and accuracy of recognition requirements continue to increase, andmulti-target recognition that a solution to enhance the efficiency and accuracy of theRFID system data collision core research topics, namely the use of anti-collisionalgorithm to enhance identification efficiency and accuracy of recognition. In thispaper, the study of the original RFID anti-collision algorithm, a deterministicalgorithm to identify high accuracy classification study: Improved system timeslotefficiency; improve the system transmitted data amount. The combination of these twotypes of the advantages is the basic idea of the algorithm, the time slot that canenhance the utilization, and can reduce the amount of data the new systemtransmission algorithm. Proposed system performance indicators: number ofpaging;-bit length; transmission delay, as a measure of the efficiency of the system ofindicators combined with algorithm theory, examples of analysis and simulationexperiments demonstrate the advantage of the algorithm in the identification efficiencyand recognition accuracy. More proof lies in the label larger number system, thealgorithm proposed in this paper will further optimize the performance of theirsystems to reduce the recognition cost and improve the efficiency of the system, andpromote RFID systems to be applied in a wider field.Access control systems, from simple to complex Internet of Things; the slowticket management system, to the high-speed vehicle toll collection system; fromsimple automated identification system data, to a very high level of security ID cardsystem, RFID systems in China’s development speed is rapid and broad development prospects, the underlying economic value is enormous. In this paper, the RFIDanti-collision algorithm research, on the basis of the original algorithm combinedadvantage of a variety of anti-collision algorithm proposed new RFID anti-collisionalgorithm, the new anti-collision algorithm in RFID system will be more effective, andmore low-cost more accurate boost for China’s economic development.
