基于单片机的门禁系统的设计

摘要

门禁系统采用89C52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LCD液晶显示电路等。

门禁系统主要由CPU、工作指示电路、振荡电路、蜂鸣器电路、门控锁电路、矩阵键盘、读卡模块、显示模块等组成。

该门禁系统采用射频卡完成刷卡进门，按刷卡出门等功能。

其工作原理为:

当刷卡时，蜂鸣器响一下，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，指示灯点亮，延时一段时间后继电器再次动作将门锁锁闭，指示灯熄灭。

当按下出门按钮时，继电器动作将门锁打开，指示灯点亮，延时一段时间后继电器再次动作将门锁锁闭，指示灯熄灭。

当输入初始密码时，若输入正确，继电器动作将门锁打开，指示灯点亮，延时一段时间后继电器再次动作将门锁锁闭。

此外，程序中还增加了射频卡权限判断的功能，当遇到合法卡时显示卡号，门锁打开，延时10s自动关闭，当遇到非法卡时不显示卡号门锁不开。

本系统设计简单、性能优良，具有一定的实用性。
