摘要
目前"物联网改变未来"的理念离不开RFID技术,在UHF RFID系统实际应用中,标签碰撞和信息安全是目前面临的两大主要问题。本文是在无源超高频RFID系统中,提出了一种新的融合型防碰撞算法,即预测检验算法,它利用二进制树搜索原理,动态调整帧时隙数;MATLAB软件仿真分析结果表明算法标签识别率及算法性能得到明显提升。
At present,the concept of "the future of the Internet of things"cannot be separated from the RFID technology.In the actual application of UHF RFID system,tag collision and information security are two major problems that are currently facing.In this paper,a new fusion anti-collision algorithm is proposed in the passive ultra-high frequency RFID system,namely predictive test algorithm,which USES binary tree search principle to dynamically adjust the number of frame slots.MATLAB simulation results show that the recognition rate and algorithm performance of the algorithm are significantly improved.
