1、 I 楼层单元门禁系统的设计 摘 要 根据现代住宅小区的安全的要求，在现代楼宇自动化的应用中，门控系统应用得十 分广泛，它提高了住宅质量和人们的生活的安全性，本课程设计要是设计出一种小型小 区的门控系统，在何处放行某些人、拒绝某些人，何时发出警报。基于 51 单片机，以 键盘密码的输入方式实现对门的出入控制，或者通过键盘输入门号的方式，进行对讲方 式住户实现开门。适用于普通楼宇单位的进入控制，可实现： 对通道进出权限的控制（密码输入进门的控制） ；对讲系统（可实现门外和住户的对 话及开门控制） 。在异常情况下（输入密码错误）实现报警； 本系统的核心器件是单片机，通过对单片机已经写入得程序的实现
2、上述功能。可实 现普通机械门锁所不能实现的自动门控系统。 关键词关键词：51 单片机；门禁系统；对讲通话系统；Proteus 仿真 楼层单元门禁系统设计 II The Entrance Guard System Based on MCU Abstract The Access control system have being using very extensive，in the modern building automation applications, what improve the quality of people life and the residence of safet
3、y. The primary written assignment for this subject is design a Small systems of Access control it base on 51-MCU, which realizing the access control with the input password or call way. This system can be applied in general building unit of access control. Its function as follows: The permissions to
4、 access control（entrance with the right pass code）；Access talkback system(the doors open and Dialogue function)；Alarm In exceptional circumstances (Illegal invasion). The MCU is the core device of this system. This system runs throughout the course of program. It can realize the function that common mechanical lock cannot achieve.
