【摘要】：传统的门禁系统采用有线数据通信方式,系统部署受到环境限制较多,其系统功能仅限于对来访人员身份的识别,无法提供或者融合进诸如便捷的户外数据采集,向移动设备端主动信息推送等新型移动应用。射频身份识别(Radio Frequency IDentification, RFID)是一种非接触式自动识别技术,经过不断发展和普及,在众多领域广泛应用。近场耦合通信(Near Field Communication, NFC)技术作为RFID在移动应用领域的先进解决方案,近年来在移动终端设备一侧迅速普及,如手机、平电脑、个人数字助理等,能提供身份识别、电子支付、信息共享等移动应用。本文融合当前大数据背景下数据业务移动推送的需求,设计一种将Zigbee传感网络、近场耦合通信以及传统门禁技术相结合的整体解决方案。该身份识别功能系统支持快速无线部署；具有传统门禁系统不可比拟的无线数据传输功能;融合近场耦合通信支持移动终端设备等优点,可广泛应用于户外场所或其他数据推送的场景中。论文主要工作包括：1、研究现有门禁系统应用现状、技术特点和发展趋势。对比分析了数种常见的短距通信技术,重点研究了Zigbee无线传感网络的技术方案。在此基础上,深入研究了NFC通信的实现原理、过程、数据格式等技术细节。重点分析了Zigbee无线传感网络技术和NFC技术融合在门禁系统中实现的可行性和必要性。2、对门禁系统进行了系统级规划与设计,并在此基础上详细设计了各个部分的硬件,详细讨论了系统原理、设计细节、计算和结果。3、基于软件工程的思想和方法对嵌入式软件和门禁系统上位机软件进行需求分析、概要设计和详细设计,实现了Zigbee协议栈功能的二次开发、NFC通信软件、外围控制器运行维护及上位机软件等软件开发、测试和调试。系统整体测试与评估结果表明,所设计的门禁系统达到预期设计要求,为解决灵活、快速部署以及数据推送等移动业务提供了有效的解决方案。
[Abstract]:The traditional access control system uses wired data communication mode, the system deployment is limited by the environment, its system function is limited to the identification of visitors, it can not provide or merge into such convenient outdoor data collection, New mobile applications such as pushing active information to the end of mobile devices. Radio Frequency Identification (Radio Frequency IDentification, RFID) is a contactless automatic identification technology, which has been widely used in many fields through continuous development and popularization. As an advanced solution of RFID in the field of mobile applications, near field coupled communication (NEM) Field Communication, NFC) technology has been rapidly popularized on the side of mobile terminal devices in recent years, such as mobile phones, flat computers, personal digital assistants, etc., which can provide identification, electronic payment, etc. Information sharing and other mobile applications. This paper combines the requirement of mobile push of data services under the current big data background, and designs a solution that combines Zigbee sensor network, near-field coupling communication and traditional access control technology. The identification function system supports rapid wireless deployment, has the advantages of wireless data transmission functions that are incomparable to traditional access control systems, and integrates near-field coupled communications to support mobile terminal devices, and so on. Can be widely used in outdoor places or other data push scenes. The main work of this paper is to study the application status, technical characteristics and development trend of the existing access control system. Several common short-distance communication technologies are compared and analyzed, and the technical scheme of Zigbee wireless sensor network is studied emphatically. On this basis, the realization principle, process, data format and other technical details of NFC communication are studied in depth. The feasibility and necessity of the integration of Zigbee wireless sensor network technology and NFC technology in the access control system are analyzed, and the system level planning and design of the access control system are carried out. On this basis, the hardware of each part is designed in detail. The principle, design details, calculation and result of the system are discussed in detail. Based on the idea and method of software engineering, the requirement analysis, outline design and detailed design of embedded software and upper computer software of access control system are carried out. The secondary development of Zigbee stack function is realized, including the software development, testing and debugging of peripheral controller operation and maintenance, and host computer software. The overall test and evaluation results show that the designed access control system meets the expected design requirements, and provides an effective solution for mobile services such as flexibility, rapid deployment and data push.
