【摘要】：当前,物联网浪潮正席卷全球,其被人们认为是继计算机和因特网之后的又一次技术革命,催生了各项相关技术迅速蓬勃发展。作为物联网技术核心基石的RFID(Radio Frequency Identification,无线射频识别)技术已成为最具发展潜力的一项新兴技术。随着人们对位置信息和定位服务需求的飞速增加,很多应用对定位信息要求更加细致准确,而传统的GPS(Global Positioning System,全球定位系统)室外定位技术渐渐不能满足应用的需求。近年来,室内定位技术受到研究人员的关注,而RFID技术其具有非接触、多目标、非视距、识别速度快和效率高等诸多优点成为国内外研究的焦点。本文研究利用RFID技术结合现代计算机信息管理技术,设计和开发人员定位管理系统,通过企业中RFID阅读器的多点识别,从而实时监控各区域中员工的位置信息等。本文的主要工作如下:(1)分析了传统的GPS室内定位技术存在的问题,并根据现代企业管理中员工实时位置的重要性,阐明了研究基于RFID技术的人员定位管理系统对于企业管理的应用价值。此外,概述了RFID技术的国内外研究现状。(2)介绍了RFID系统组成、工作原理、应用领域以及RFID定位算法,分析了时间自动机两个方面的理论知识,为下文系统分析、设计和性能验证奠定了理论依据。(3)针对RFID采样信号传输过程中突发干扰造成RSSI值异常问题,提出了一种基于密度聚类的RSSI加权质心定位算法。通过OPTICS算法消除RSSI集合中的离群点,并通过加权质心算法实现RFID中标签的位置定位。基于RFID技术的人员定位系统设计、开发和测试。从系统架构设计方面将系统划分为三个子系统:RFID定位中间件、位置信息管理、员工部门管理,并采用面向对象的UML(Unified Modeling Language,统一建模语言)模型详细描述系统的需求分析和设计部分。系统测试部分包括上层应用系统的功能测试以及RFID定位中间件子系统中设备标签读写测试和读写安全性测试。(4)采用UPPAAL建模工具对系统中的标签、阅读器、处理器和后台数据库四个核心模块进行建模,并从系统活性、安全性和定位精确性方面进行了验证,实验结果表明:系统满足了以上三个方面的需求。
[Abstract]:At present, the tide of Internet of things is sweeping the world, which is regarded as another technological revolution after computers and the Internet, which has given birth to the rapid development of various related technologies. As the core of Internet of things technology, RFID(Radio Frequency Identification (RFID) technology has become the most promising emerging technology. With the rapid increase in the demand for location information and positioning services, many applications require more detailed and accurate positioning information, but the traditional GPS(Global Positioning system (GPS) outdoor positioning technology is gradually unable to meet the needs of the application. In recent years, indoor positioning technology has attracted the attention of researchers, and RFID technology has many advantages such as non-contact, multi-target, non-line-of-sight, fast recognition speed and high efficiency. In this paper, RFID technology combined with modern computer information management technology is used to design and develop a position management system for personnel, which can monitor the position information of employees in every area in real time through the multi-point identification of RFID reader in the enterprise. The main work of this paper is as follows: (1) analyzing the problems existing in traditional GPS indoor positioning technology, and according to the importance of real-time location of employees in modern enterprise management. The application value of personnel positioning management system based on RFID technology to enterprise management is expounded. In addition, the research status of RFID technology at home and abroad is summarized. (2) the composition, working principle, application field and RFID location algorithm of RFID system are introduced, and the theoretical knowledge of time automata is analyzed. The design and performance verification provide a theoretical basis for the design and performance verification. Aiming at the abnormal RSSI value caused by the burst interference during the RFID sampling signal transmission, a new RSSI weighted centroid localization algorithm based on density clustering is proposed. The outlier in RSSI set is eliminated by OPTICS algorithm, and the location of label in RFID is realized by weighted centroid algorithm. Design, development and test of personnel positioning system based on RFID technology. In terms of system architecture design, the system is divided into three subsystems: RFID positioning middleware, location information management, employee department management, The requirement analysis and design of the system are described in detail by using the object-oriented UML(Unified Modeling language (Unified Modeling language) model. The system test part includes the function test of the upper application system and the device tag read-write test and read-write security test in the RFID positioning middleware subsystem. The four core modules of processor and backstage database are modeled and verified from the aspects of system activity, security and positioning accuracy. The experimental results show that the system meets the requirements of the above three aspects.
