【摘要】：RFID技术最大的优点是快速扫描、移动物体识别和非接触式识别,信息的自动采集代替了传统的人工数据采集工作,大大提高了数据采集效率。目前,许多档案馆的信息管理工作均开始运用自动化辅助的手段,并设计了符合自身需求的管理系统。本论文的档案管理系统正是在RFID技术的基础上进行的研究和设计。本文首先通过阅读大量文献资料,了解国内外RFID技术和档案管理系统的研究现状,简单介绍了RFID技术以及RFID系统的组成和工作原理,并将RFID技术与传统的条码技术做了对比。然后对档案管理系统做了全面的需求分析和可行性分析,提出了基于RFID的档案管理系统的解决方案。在RFID标签防碰撞技术方面,本文首先对基本的RFID标签防碰撞算法做了分析与研究,然后将基于二进制树搜索防碰撞算法做了改进与优化,并在此基础上提出了一种基于记忆化搜索的RFID防碰撞算法,详细介绍了记忆化搜索防碰撞算法的执行过程,并对算法做了深入的理论分析与对比仿真。最后,论文给出了RFID档案管理系统的具体实现方法,对档案管理系统的数据采集与处理模块、档案管理模块、用户管理模块和数据库模块进行了设计,并结合档案查询界面、用户管理界面、数据库设计界面和相关实物图等介绍了各个模块的功能和实现方法。本文根据实际需求提出的档案管理系统的设计方案,可有效解决传统的档案管理工作中长期存在的管理效率低、安全性不高等问题。论文的创新点为提出了一种基于记忆化搜索的RFID防碰撞算法,仿真结果表明,识别相同数量的标签,读写器的请求次数和总的传输数据量比RBS算法分别减少33.67%和66.34%,且不会出现标签漏读的现象,效果明显,应用于档案馆等电子标签位置变化不大的场景中,可大大提高数据采集效率。
[Abstract]:RFID technology has the advantages of fast scanning, moving object identification and non-contact identification. The automatic collection of information replaces the traditional manual data collection, and greatly improves the efficiency of data acquisition. At present, many archives information management work has started to use the automation auxiliary means, and has designed the management system which conforms to own demand. The file management system of this paper is based on RFID technology research and design. In this paper, we first read a lot of literature to understand the current situation of RFID technology and file management system at home and abroad, briefly introduce the RFID technology and RFID system composition and working principle, and compare RFID technology with the traditional bar code technology. Then, the paper makes a comprehensive demand analysis and feasibility analysis on the file management system, and puts forward the solution of the file management system based on RFID. In the aspect of anti-collision technology of RFID tags, this paper firstly analyzes and studies the basic anti-collision algorithm of RFID tags, and then improves and optimizes the anti-collision algorithm based on binary tree search. On this basis, a kind of RFID anti-collision algorithm based on memory search is proposed, and the execution process of memory search anti-collision algorithm is introduced in detail, and the theoretical analysis and comparative simulation of the algorithm are done. Finally, the paper gives the realization method of RFID file management system, designs the data acquisition and processing module, the file management module, the user management module and the database module of the file management system, and combines the file query interface. The user management interface, database design interface and related physical diagram are introduced. In this paper, the design scheme of archives management system is put forward according to the actual demand, which can effectively solve the problems of low management efficiency and low security in the traditional archives management work for a long time. The innovation of this paper is to propose an RFID collision prevention algorithm based on memory search. The simulation results show that the same number of tags are recognized. The number of requests and the total amount of data transmitted by the reader are 33.67% and 66.34% less than those of the RBS algorithm, respectively, and the phenomenon of missing the tags will not appear. The effect is obvious, so it can be used in the scene where the position of the electronic tag is not changed much, such as archives, etc. The efficiency of data acquisition can be greatly improved.
