基于SOPC的射频卡实时消费记录系统设计

摘要

基于使用户刷卡消费的数据可进行采集存储的目的,采用了在FPGA平台上设计一种射频卡实时消费记录系统的方法.该系统采用了FATFS文件系统,可将用户数据及时保存到SD卡之中.通过对软硬件模块和上位机的设计,采用FPGA为开发平台,对用户刷卡消费的记录写入到SD卡中.利用SD卡的移动性,可方便地实现与计算机的数据交换,达到数据分析的目的.此法便于客户对消费记录的核对,具有实际商业价值.%A FPGA-based RF CARD real-time consumer records system is designed for the purpose of the data of user's credit card spending can be collected and stored. The recorder support FATFS file system , user consumption data can be stored in SD memory card as soon as possible. By the design of hardware and software modules and PC, credit card spending records is written to the SD card based on FPGA. Using the mobility of the SD card, it can be easily achieved with the computer data exchange, and achieve the purpose of the data analysis This method is easier for customers to check on consumer records with the actual commercial value.
