射频识别卡读写模块的设计与应用 摘 要 I 摘 要 随着电子信息技术的发展，智能卡（IC 卡）已经在我们的生活中随处可见射频识别卡正逐渐取代传统的接触式 IC 卡，成为智能卡领域的新潮流研究、开发射频识别卡的读写技术与读写设备，对其推广有着重要的实际意义 本文首先介绍了射频识别卡及射频识别系统的工作原理为了使应用系统的开发人员无需掌握复杂的射频识别技术就可快速开发射频识别卡应用产品，本文 基于模块化的设计思想设计开发了射频识别卡 Mifare1 的读写模块 该读写模块不仅能完成对射频识别卡的控制和读写操作，而且可供用户在其基础上进行二次开发文中详细讨论了读写模块的具体实现硬件部分介绍了系统的组成、MCU 与读写芯片的接口设计与硬件电路的实现软件部分重点阐述如何实现射频识别通信的底层驱动，并在此基础上将卡片的操作用函数形式封装，以供用户调用函数的封装严格按照软件工程的要求，具有硬件无关性，方便用户二次开发然后，给出了读写模块的两个应用实例： RFID 卡通用读写卡器及带网络接口的考勤机，简要的介绍了其设计方法和用途。

最后，对本文所做工作进行了总结，并给出今后研究工作的展望 关键词：射频识别，IC 卡，读写设备 作者：徐丽华 指导老师：王宜怀 ABSTRACT The Design and Application of Read/Write Module of RFID Card II ABSTRACT With the rapid development of electronic information technology，smart cards (IC card) are now very popular in our life. Radio Frequency Identification (RFID) card is becoming a new fashion in the application field of smart card, replacing the traditional contacting IC card. So it is of great practical significance to study the technology of RFID Card and develop the read/write device of RFID card for its generalization. The common concept of the RFID card and the basic working principle of RFID system are explained chiefly in the first part of this paper. Then, a read/write module of Mifare1 RFID card is developed, based on the modular designing mind. The users of application system may develop their practical products rapidly with our module without understanding the details of RFID technology. The read/write module can not only do the control and read/write operations of the RFID card, but also can be redeveloped. The way to implement the read/write module is discussed in detail, including two parts, the hardware and the software. The former part includes the constitutes of the system, the design of the interface between MCU and the chip of RFID module, and the realization of the hardware circuits. And the latter mainly introduces how to drive the RFID communication and encapsulate the operation of the card into functions which can be transferred by the customers conveniently. The functions are irralated with hardware by doing its encapsulation according to the rules of software engineering.Then, two application examples based on read/write module are given, one is a general read/write device and the other is a check- in machine with network interface. At last, all the work are summarized and a research prospect of the subject in future is promised .
