RFID关键技术理论的研究

【摘要】：近几年随着物联网的迅猛发展,射频识别(Radio Frequency Identification, RFID)技术作为其关键技术之一也获得越来越大的发展。RFID技术拥有快速扫描、非接触识别以及穿透性强等特点,逐渐被广泛的应用于军事、医疗、交通、库存控制以及供应链管理等各个领域。据权威报告统计数据,2008年全球RFID市场规模达到52.5亿美元,全球共售出19.7亿个标签。RFID发展已从技术研发阶段进入到应用驱动阶段。而在RFID技术迅猛发展的同时,很多问题需要解决。因此,本文针对RFID的关键技术理论展开了研究,主要包括以下两个方面的内容： 有关标签数量估计的相关工作都考虑一个系统中仅部署一个阅读器。而在实际应用的系统中,一个阅读器很难覆盖系统中所有的标签。故本文针对在系统中部署多个阅读器时标签数量估计问题展开了研究。而在系统中部署多个阅读器后,标签数量估计协议就遇到了重复计数的问题,即在阅读器覆盖范围的重叠区内的标签被重复计数。本文研究了在部署有多阅读器的大型RFID系统中怎样能够快速估计出标签的数量。在采用一种精巧的方法消除了重复计数问题的基础上,进而提出了一个新颖高效的多阅读器标签数量估计协议(EMR)。 同时,本文也对伪造标签识别这一具有实际意义的问题进行了深入研究。在某些领域中尤其在奢侈品管理行业,每件物品都绑定具有唯一序列号的标签用来鉴别商品的真伪。由于伪造商品不仅给消费者带来了巨大的经济损失,而且给生产者的品牌带来了严重的负面影响。因此如何快速识别伪造商品就成为一件具有实际意义的重要问题。现有相关算法只能检测系统中是否存在伪造标签,但是无法准确识别出系统中所有的伪造标签。本文提出了基于Bloom filter的伪造标签识别协议(CIP)。在此基础上,考虑到标签的能量效率,又提出了能量效率更高的增强型伪造标签识别协议(ECIP)。
[Abstract]:With the rapid development of Internet of things in recent years, radio frequency identification (Radio Frequency Identification, RFID) technology, as one of its key technologies, has gained more and more development. RFID technology has the characteristics of fast scanning, non-contact identification and strong penetration. It has been widely used in military, medical, transportation, inventory control and supply chain management. According to authoritative report statistics, the global RFID market size reached $5.25 billion in 2008, and 1.97 billion labels were sold worldwide. The development of RFID has moved from technology development stage to application driving stage. With the rapid development of RFID technology, many problems need to be solved. Therefore, this paper studies the key technology theory of RFID, including the following two aspects: only one reader is deployed in a system in the related work of tag number estimation. In practical applications, it is difficult for a reader to cover all tags in the system. Therefore, the problem of tag number estimation when deploying multiple readers in the system is studied in this paper. After the deployment of multiple readers in the system, the tag quantity estimation protocol encounters the problem of repeated counting, that is, the label in the overlapping area covered by the reader is repeatedly counted. This paper studies how to quickly estimate the number of tags in a large RFID system with multiple readers. In this paper, a novel and efficient multi-reader tag estimation protocol (EMR). Is proposed on the basis of eliminating the repeated counting problem by using a sophisticated method. At the same time, this paper also carries on the thorough research to the false label recognition which has the practical significance question. In some areas, especially in the luxury management industry, each item is bound to a label with a unique serial number to identify the authenticity of the product. Counterfeit goods not only bring huge economic losses to consumers, but also bring serious negative effects to producers' brands. Therefore, how to quickly identify forged goods has become an important issue of practical significance. The existing algorithms can only detect the existence of forged labels in the system, but can not accurately identify all false labels in the system. In this paper, a forged label recognition protocol (CIP). Based on Bloom filter is proposed. On this basis, considering the energy efficiency of tags, an enhanced forged label recognition protocol (ECIP).) with higher energy efficiency is proposed.
