2014年IC卡门禁控制系统设计.doc

毕业设计（论文）中文摘要 基于51系列单片机的智能IC卡门禁控制系统设计 摘要： 本设计采用AT89C51 单片机作为控制核心，外围加蜂鸣器控制电路、开门指示灯电路、电控锁控制电路以及8位数码管显示电路等。门禁系统主要由CPU、复位电路、电源指示、工作指示、振荡电路、蜂鸣器电路、门控锁电路、读卡模块、显示模块等组成。采用IC卡完成刷卡进门，通过具体程序设计实现：当刷卡时，如卡权限获得允许，显示模块显示卡号，同时继电器动作将门锁打开，指示灯熄灭；当遇到非法卡时不显示卡号，门锁不开，蜂鸣器发出警报。本系统设计简单、性能优良，具有一定的实用性。 关键词： 门禁系统 单片机 读卡器 电控锁，IC卡 毕业设计（论文）外文摘要 Title Based on the 51 Series MCU intelligent IC card access control system design Abstract This design uses AT89C51 single chip microcomputer as the control core, periphery and a buzzer control circuit, the door indicator light circuit, the electric control lock circuit and the 8 digital tube display circuit. Access control system is mainly composed of CPU, reset circuit, the power indicator, work instructions, oscillation circuit, a buzzer circuit, lock circuit, card reader module, display module and other components. Using IC card to complete the card door, through specific programming: when the swipe of a card, such as card access permit, the display module for displaying the number, at the same time relay will open door locks, the indication lamp is off; when the illegal card does not show the card number, door not open, buzzer alarm. This system has the advantages of simple design, good performance, has a certain practicality.
