Abstract: With the continuous development and application of RFID technology,positioning system based on RFID technology has become a hot issue.This paper introduces a kind of RFID localization algorithm studying readers network and storing the topology of the readers network as motherboard in system,which matches the collection of the tracking vector with the motherboard to find the best path.Experiments show that,RFID network in the large space tracking algorithm can accurately track the object and detect reader working state;when the reader fails,the algorithm can still track the positioning of objects,and has good robustness.

Key words: Radio Frequency Identification(RFID), network tracking algorithm, reader network topology, large space, reader state

摘要: 随着RFID技术的不断发展和应用,基于RFID技术的定位系统已成为当前研究的热点问题。详细介绍了一种RFID定位算法,以阅读器网络为研究对象,存储在系统中的阅读器拓扑结构为母板,通过收集到的跟踪向量与母板匹配,寻找最佳路径。实验表明,RFID网络跟踪算法在大空间中能够准确地跟踪物体、检测阅读器工作状态;当阅读器出现故障时,算法仍能对物体跟踪定位,具有较好的鲁棒性。
