本 科 毕 业 论 文（设 计） 摘要 射频识别(Radio Frequency Identification,RFID)是一种非接触式的自动识别技术，它通过射频信号自动识别目标对象并获取相关数据，识别过程无需人工干预，是一种新的自动识别技术[1]。RFID是利用射频方式进行非接触双向通信IC 射频卡成功地解决了无源(卡中无电源) 和免接触这一个难题。RFID具有非接触、、、可识别运动目标等优点,因此，对射频卡的开发应用也具有一定的现实意义。本文的设计是基于Philips公司的Mifare1 S50/S70芯片的射频识别系统的设计方案，制作一的射频识别读写器RF 接口电路，制作相应的硬件电路模块，分析非接触式IC 卡系统的通信协议，通过Keil C软件编程实现读写器与非接触式IC 卡系统的通信,并完成校园卡考勤系统。 关键词: RFID; 自动识别; ARM; 非接触式IC卡; Keil C Abstract RFID is a non-contact automatic identification technology,it identify target and get the related data through radio frequency signal automatically,the identification process without human intervention, is a kind of new automatic identification technology. RFID for non-contact two-way communication by the way of radio frequency, and non-contact IC radio frequency card has successfully solved the difficulty problems: without power supply and non-contact. RFID has many advantages: non-contact,long-distance work,good adaptability for environment and can recognize the moving objects，RFID technology has appeared in more and more field,so the development and application of radio frequency card also has certain practical significance. The design of this article is based on the Mifare 1 S50 / S70 chip radio frequency identification system which produced by Philips company,and then design a RFID read-write device and the corresponding hardware circuit module and the RF interface circuit based on ARM microprocessor,and completed the communication between the reader and the non-contact IC card system and campus card attendance system through the software programming with Keil C at last.
