摘 要
本文介绍了一种用于门禁管理系统的射频读卡器的设计过程，实现卡上信息的识别和读取。我主要完成了硬件的设计调试和部分软件的设计和调试工作。
对于硬件部分，完成读卡器电路的设计和调试工作。此设计主要运用AT
对于软件部分，要求实现IC卡内部信息的读写以及与上位管理计算机的通信。即主要通过串口通信程序的设计和调试，最终实现当没有卡进入时显示时钟，有卡进入时则读卡内数据并将数据显示在电脑屏幕上，通过读卡程序和对DS1302编程实现。
此设计最终完成了硬件调试并实现了部分软件基本程序的调试工作，可以在上位PC机上读取卡上的信息。

ABSTRACT
This thesis introduced the design process of a kind of radio frequency (RF) read card device which used for controlling at entrance guard system.it is used for identifying and reading information.I mainly completed the design and the adjustment of the circuit, the design of parts of software and debugging.
For the hardware ,I main completed the design of the reader device circuit and adjustment. This design have implemented identifying Mifare 1 RF card and acquiring the informations in cards using of AT
For the software , the design requests carrying out the read/write of the information in Mifare card and the correspondence with calculator as managing .Then end realization that the system will display the clock when there is on card entered into the scope of RF antenna ;when the card entered into that ,the reading card data will be displayed on the screen of computer. The realization of this process is by designing of string correspondence procedure, reading card procedure and DS1302 procedure.
This design completed the work of adjusting hardware ,carring out parts procedure of softwares and debugging endly,can be the information of card on the PC.
