摘　　要：RFID作为物联网感知层的关键技术之一,广泛应用于仓储物流,产品防伪等各个领域。文中首先介绍了RFID系统中的关键组成部分并详细分析了各部分的工作原理,然后重点分析了制约RFID技术发展的关键问题—碰撞问题,主要包括RFID中的多标签,标签-阅读器以及阅读器-阅读器这三种碰撞及其对应的防碰撞算法。文中针对RFID碰撞问题的相关研究工作,对防碰撞算法的后续研究具有一定的参考价值。Radio Frequency Identification can serve as critical technology elements for a wide range of future application in 1ogistics, Product forgery-proof recognition etc. This paper firstly discussed the crucial part in RFID system and detailed analysis of its parts. Then this paper put emphasis on the collision problems that limit the development of RFID technology, including three types of collision problems and its anti-collision algorithm： multi-tag collision, tag-reader collision and reader-reader colli- sion. On account of collision problem in this paper is worthy for reference in the following research.
