智能门禁系统设计 摘要：随着射频技术的飞速发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、便捷和实用。射频标签是采用非接触式，具有读写速度快、功耗低等优点。 本文设计了一种采用RFID（Radio Frequency IdentificationRFID；智能门禁；IC卡；STC89C52 Design of intelligent access control system Abstract：With the rapid development of radio frequency (RF) 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 todays 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 system of the domestic and foreign development status and trends, describes the problems existed in current access control system, leads to the purpose and significance of the topic research, based on the design scheme of the intelligent entrance guard system, and on the radio frequency identification technology is discussed in this paper, introduces the radio frequency identification system, the working principle, main technical parameters and related key technologies. Secondly, the hardware and software design of the system are introduced, the choice of hardware circuit, the design of the hardware driver, the design of serial communication program, etc.. Finally, summary the paper, summarizes the research contents and results of this paper, when the user enters the detection range of access control system, the system will automatically
