1、摘要摘要非接触式IC射频智能卡在金融,经济等社会领域中起着重要的作用,本文着重研究了基于单片机的无线智能IC射频卡应用于考勤机的设计方法。该系统以Atmel公司生产的AT89C52为微处理器,通过以IC射频卡考勤系统的设计为具体研究方法,讨论了应用系统中硬件开发和软件系统的设计。本论文首先对非接触式IC卡进行了概述,紧接着重点介绍了Philips公司的MIFARE技术,对MIFARE卡片和MIFARE非接触式IC卡的读写组件MCM200进行了全面的阐述;在此基础上,论文详细地阐述了非接触式IC卡读卡器的硬件和软件设计,给出了各部分的实际电路图。本文的硬件设计包括电源
2、供应电路、LCD状态显示电路、蜂鸣器驱动电路、RS232通信电路、MCU的连接、MCM200接口电路和读卡器天线,时钟电路,时钟监控电路等几部分的设计。软件设计分为对MCM200的应用程序的设计、对读卡器其他电路的应用程序设计和主程序设计三个部分,相应部分都给出了具体程序或程序流程图,并对部分程序进行了详细的说明。关键词:IC智能卡,射频,读写器设备,LCD,AT89C5AbstractAbstractWirelessICsmartcardisplayingimportantroleinsocietyfieldsuchasfinanceandeconomy.This
