智能门禁系统设计摘要：随着射频技术的飞速进展及其应用范围的越发宽广，在身份识别和安防等行业，门禁系统作为智能建筑的重要单元越来越得到重视，从原始的机械锁操作到如今刷卡的智能门禁系统。射频识别技术的出现弥补了原来门禁系统的不足，而且让门禁系统变的更加安全、便捷和有用。射频标签是采纳非接触式，具有读写速度快、功耗低等优点。本文设计了一种采纳 RFID（Radio Frequency Identification）技术的高安全性的智能门禁系统。首先分析了门禁系统的国内外进展现状和趋势，阐述了门禁系统当前存在的问题，引出课题讨论目的和意义，给出了智能门禁系统设计方案，并对射频识别技术进行了阐述，讨论了射频识别系统的工作原理、主要技术参数和相关的关键技术。其次完成了系统硬件和软件设计，对硬件电路芯片的选择、硬件驱动程序的设计、串口通讯程序的设计等作出了具体详细的分析。最后对智能门禁系统进行检测，当使用者进入门禁系统的检测范围时，系统会自动猎取身份信息确定该使用者是不是授权用户，并且记录进出人员信息，对非授权用户发出报警信号。经试验测试，达到设计要求。关键词：RFID；智能门禁；IC卡；STC89C52Design of intelligent access control systemAbstract：With the rapid development of radio frequency (RFID) technology and its application more and more broad, in the identification and security industries, access control system as an important element of intelligent building more and more importance has been attached to the, from the original mechanical lock operation to today's credit card intelligent access control system. The emergence of radio frequency identification technology has made up the shortage of the original access control system, and makes access control system become more secure, convenient and practical.. Radio frequency tags are non-contact, read and write fast and low power consumption.In this paper, a high security intelligent access control system is designed, which is based on RFID (Frequency Identification Radio) technology.. Begins with an analysis of the access control ...
