摘要
本文设计了能对低频和高频RFID卡进行操作的双频RFID读写系统。系统基于ARM微处理器S3C44B0X,利用S3C44B0X的内部接口实现与RFID模块和其它外设的连接,简化了硬件。软件设计中,通过对ARM嵌入式系统的编程实现对RFID卡的读写、显示以及数据的存储、查询等功能。系统还可通过USB接口与上位机(PC)连接,使用方便灵活。
This paper introduces the design of a double-frequency RFID read-write system which can access low and high frequency RFID cards. Based on the ARM processor of S3C44B0X, the system connects RFID modules and other devices through the inner interfaces of S3C44B0X. So the hardware is simplified. In software design, the functions of read and write, data display, information storage and query are realized by programming on ARM embedded system. Besides, the designed system can be connected with PC through USB. So it is very convenient and flexible to use.
