1、本科生毕业设计智能门禁系统的设计制作The Design of Intelligent Access System摘 要门禁系统是一种新型的智能管理模式，对于现今的安全管理起了不可替代的作用。在科技发展和社会财富不断增长的今天，为了加强主要工作管理区、进出口、珍贵物品的储存室、设备的控制管理中心、电梯口等重要通道安全防护处理办法，开发相应的智能门禁系统，来识别进出人员的身份资料，对进出通道进行安全防护和控制就有了很大的必要性。通过对当代门禁系统发展概况和技术的研究，本方案提出以单片机为中央控制系统，加 LCD 液晶显示电路、键盘输入电路、读卡电路等外围电路，来完成非接触式 IC 卡和密码两种方
2、法控制的门禁系统。在具体的使用中，当感应卡接近读卡机或有密码通过键盘输入时，合法的卡信号正确的密码，继电器工作，电锁便会自动打开，非法卡和错误的密码将被禁止访问，并在显示器上提示卡是否合法，密码是否正确。系统设计简单，性能可佳，实用性较强。关键词：智能门禁系统；非接触式 IC 卡；键盘密码ABSTRACTAccess Control System is a new type of intelligent management,security management for today played an irreplaceable role.
