摘要
该文设计的门禁系统所实现功能是,Mifare S50 IC卡进入RFID高频读写器感应区识别卡号,然后与数据库内数据比对,最后合法后再由AT89C52单片机通过控制继电器控制电子锁的开启与关闭。设计的步骤包括,进行需求分析并确定必要的系统功能;选择高频射频卡、读写器和单片机等硬件的型号;再进行软件设计;最后进行调试使各个模块间正常通信,实现预定功能。
The function of the entrance guard system designed in this paper is that the card number of Mifare S50 IC card can beidentified as near the RFID high frequency read-writer induction area, and then the data is compared with the database. Finally,the opening and closing of the electronic lock is controlled with the AT89 C52 single chip microcomputer by the control relay. Thesteps of the design include the requirement analysis and the determination of the necessary system functions, the selection of thehardware models such as high frequency radio frequency card, reader and writer and MCU, and then the software design; the finaldebugging for the normal communication between each module to realize the predetermined function.
