摘要
基于嵌入式以太网的射频卡读卡器是一种可以通过网络进行远程身份认讧的设备。读卡器利用Freescale带有以太网模块的32位ColdFire系列中MCF52233芯片进行设计,可以直接接入局域网。该款读卡器可以应用在高校上课签到、实验考勤等管理系统中。阐述了基于嵌入式以太网的射频卡读卡器的设计思想、电路设计和实际应用。
The radio frequency card reader based on Ethernet is applied for remote authentication in some college management systems, like class registration and experiment attendance management. In this paper, we introduce the design ideas of this equipment, as well as the circuit design process and some applications.
