摘要
本文以车联网中RFID技术应用为基础,结合车辆号牌实际应用环境的特点,针对RFID系统通信过程中的碰撞问题进行研究。以二进制防碰撞算法为基础,将标签分段法与ACT算法相结合进行算法改进,对二进制防碰撞算法时延性长、数据量有所冗余的特点加以改进,减少了碰撞时隙及空闲时隙,避免了重复路径,进而提高系统效率。
This paper is based on the application of RFID technology in the Internet of cars,and contact the characteristics of vehicle brand identity,and study the collision in the data communication process of RFID system.Based on the analysis of the traditional binary tree anti-collision algorithm,the features of long ductility and data volume of binary anti-collision algorithm are improved,reducing the collision time slot and idle time slot,avoid the repeated paths,and then improve the efficiency of system.
