基于Linux的RFID交互系统的设计与实现

Design and implementation of RFID interactive system based on the Linux

为了让射频识别的用户可以根据各自的权限进行相应的操作,本文提出了一款基于Linux的RFID交互系统的设计实现方案。该系统的ID识别模块通过串口与安装了Linux系统的计算机进行通信,Linux端运行应用程序,读取串口传递进来的ID卡信息,通过查找数据库,可以判断持卡用户权限,同时允许用户通过液晶显示屏进行相关操作。实际应用表明,该系统设计灵活、操作简便、识别准确,同时人机交互部分可根据用户权限展现不同的界面供用户进行相应操作,更加智能化和人性化。

In order to allow the user who are identified through the radio frequency to take the appropriate action according to their respective permissions. This paper presents the design and implementation of RFID interactive systems based on the Linux. Its ID identify module can communicate with the computer which installed the Linux operating system through the serial port. The Linux run the application, and read the ID card information pass through the serial port. Then the Linux checks the database to determine the privileges of cardholders, and allow the users to do some related view operations through the LCD. The practical application shows that the system is flexible design, easy operation and accurate identification. At the same time human-computer interaction can show a different interface for the user to take same corresponding operation according to user permissions, which makes the system more intelligent and humane.
