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。

Title Based on the 51 Series MCU intelligent IC card access
control system design
Abstract
This design uses AT89C51 single chip puter 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 posed of CPU, reset circuit, the power indicator, work instructions, oscillation circuit, a buzzer circuit, lock circuit, card reader module, display module and ponents. Using IC card plete 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.
