摘　　要：RFID(无线射频识别技术)是一种被广泛应用在物联网系统中的自动识别技术,当前在实际应用场景中的标签碰撞问题是影响RFID性能的重要因素。本文针对经典RFID防碰撞算法中存在的信息冗余大、运行效率低的问题,对算法进行了改进,在信息预处理的基础上基于碰撞位信息来构造二叉树,有效减少了通讯量,提升了识别效率,为进一步完善RFID系统的功能提供了新的思路。Radio Frequency Identification Technology(RFID)is an automatic identification technology that is widely used in the Internet of Things system.At current,the tag collision problem in practical applications is an important factor affecting the performance of RFID.Aiming at the problem of large information redundancy and low operational efficiency in classical RFID anti-collision algorithm,the article improves the algorithm.Binary tree is constructed based on the information of collision information on the basis of information preprossing,which effectively reduces the communication volume and improves the identifying efficiency and provides new ideas for further improving the function of the RFID system.
