RFID读写器设计 摘 要 随着电子信息技术的发展,智能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。近几年来，非接触式射频卡的高度安全必威体育官网网址性和使用简单等特点， 使之在各领域的应用中异军突起，应用前景十分广阔。与传统的接触式卡相比，利用射频识别技术开发的非接触式识别器，无论在系统寿命、防监听、防解密等性能上都具有很大的优势。为此，本文给出了利用ATMEGA16、MF-RC500、Mifare卡来构建非接触式读写器。 论文首先详细介绍了射频识别技术的历史、进程、在各行各业的应用及对未来的展望；还介绍了射频识别技术相对与传统技术的优点；提出了毕业设计的内容和论文结构；其次介绍了射频识别系统的工作原理以及所采用的射频芯片和射频卡的内部结构，系统的分析讨论了射频识别技术在各个频段的应用及对比；再次给出了一个实用的设计方案，论述了设计思路以及硬件、软件的设计过程；最后根据仿真结果做出总结论述，并提出了一些尚待解决的问题。 关键词：射频技术，智能卡，应答器，RC500 RADIO FRIQUENCY IDENTIFICATION CARD READER DESIGN ABSTRACT With the rapid development of electronic information technology, smart cards are now very poplar 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 and write device of RFID card for its generalization. In the last few years, non-contact radio frequency cards high security secrecy and use simple and so on characteristics, causes it to be sudden appearance in various domains application, the application prospect is very broad. With the traditional contact card compared, using radio frequency recognition technique development non-contact recognizer, regardless in performance and so on system life, against monitor, against decipher has the very big superiority. Therefore, this article gave using ATMEGA16, MF-RC500, the Mifare card has constructed the non-contact reader-writer. First, this article describes the history,the course, the using in the every walk of life and the future of radio frequency identification technology detailedly.And introducing the merit of the radio frequency identification technology relative to the traditional technology,and then bring forward the content and the structure of the graduation project. Second, this article includes the operational principle of the radio frequency identifica
