Research On High-speed Mobile Multi-objective Vehicle Identification Method Of RFID Technology

RFID technology as one of the key technologies in the things networking, because itselectronic label has small volume, long distance and identification without manualintervention, information storage, information read short time etc, in logistics,manufacturing, transportation, public information service, etc widely used. But RFIDtechnology on high speed moving object recognition when still have certain restriction,mainly displays in the RFID technology in vehicle identification management with radiofrequency operation distance increase and the increase of data transmission, collisionproblem in RFID system is very outstanding. Practical application inevitably will appearmore vehicle target in recognition area, resulting in the communication between the signalinterference, can’t identify target, lost information. Design the good performance ofcollision RFID system can also identify into the identification range of all vehicle target,the system efficiency is also will greatly improve. Therefore, collision technical designquality, to a great extent determine the RFID system performance and its application field.At present there are two commonly used the collision algorithm, ALOHA method and thebinary tree algorithm, the algorithm although in a certain extent realize collision algorithm,but in high speed moving object still have defects and the insufficiency.This paper analyzes their improvement ideas and realization process. Put forward thecorresponding optimization algorithm: control unit, speaking, reading and writing,speaking, reading and writing range, reduce the reader to send power, and to realize thesimulation of Matlab, the simulation to see improve RFID collision algorithm in highspeed mobile multi-objective vehicle identification management more effective.This paper work and innovation points are as follows:(1) mainly introduced this topic research background, research significance, theresearch status at home and abroad, and RFID communication system developmentchallenges, etc., and illustrate the prospect of RFID.(2) detailed introduces the RFID system composition, operating principle, and readernetwork standard.(3) detailed introduction ALOHA correlation algorithm, in-depth study of the collisionalgorithm based on binary, and put forward the corresponding improvement algorithm.(4) by means of simulation algorithm performance analysis, compare the basicalgorithm and improved algorithm performance advantages and disadvantages.Through the simulation results show that, compared with basic collision algorithm isconcerned, improved binary tree RFID collision algorithm, improve the utilization rate of channel, the corresponding optimization algorithm. Algorithm used in high-speed mobilevehicle identification management, is between vehicle RFID communication error can bereduced, the design is in the original algorithm, and easy to realize.
