射频卡身份识别系统设计 Person?Identification System Design of RFID Card 摘 要 随着科学技术的飞速发展，单片机的应用正在不断地走向深入。单片机技术应向着数字化控制，智能化控制方向发展。门禁 , 又称出入管理控制系统(ACCESS CONTROL SYSTEM)是一种管理人员进出的数字化管理系统射频识别技术是一项利用射频信号通过空间耦合(交变磁场或电磁场)实现无接触信息传递并通过所传递的信息达到识别目的的技术。射频识别是非接触式的自动识别，它通过射频信号自动识别目标对象并获取相关数据，识别工作无须人工干预，可工作于各种恶劣环境。技术中标签与读写器通过无线射频信号交换信息由于RFID标签具有非接触识别、可识别高速运动物体、抗恶劣环境、必威体育官网网址性强、可同时识别多个识别对象等突出特点，射频标签已被广泛应用于工业、商业、交通运输、物流物品管理系统畜禽检疫管理等众多领域。Abstract With the rapid development of science and technology, the application of single-chip microcomputer is continuously deepening. Single-chip technology should be towards the digital control, intelligent control of direction. Access Control, also known as access management control system (ACCESS CONTROL SYSTEM). Managers access to a digital management system. Radio frequency identification technology is usage of a radio frequency signal through space coupling (alternating magnetic field or electromagnetic field) to achieve non-contact transmission of information and through the message to identify the purpose. RFID is non-contact automatic identification, it gets target and relevant data through the radio frequency signal automatically, identifies without human intervention, can work in a variety of harsh environments. In RFID technology, labels and readers exchange the information through radio frequency signals. As the RFID tag has a non-contact identification, it can identify high-speed objects, anti-poor environment, confidentiality, identify multiple targets simultaneously, such salient features making it widely used in industry, commerce, transportation, logistics, materials management systems, livestock quarantine management and many other fields. This article describes the combination of single-chip module RF01D reader program. Inductive RF01D reader module is aimed at 125KHz contactless chip RFID reader designed modules. It is currently available in the market for 125KHz contactless RFID chip reading and data information to judge. RF01D the syst
