摘 要
当前，随着科技的发展，人们的生活水平得到了很大的提高，使得人们对个人的财产及其个人的人身安全重视程度越来越高，此次设计一款基于单片机的门禁控制器设计，主要是为了解决当前大部分用户使用的密码锁在输入密码锁被旁人盗取，或者存在有人多次输入密码从而盗取用户密码，给用户造成财产损失。为了防止密码被不法分子试错打开，本设计以STM32为主控芯片，利用单片机的运算和控制功能，并使用RFID进行刷卡开门，通过OLED显示学生姓名、班级、学号等信息，通过非接触红外触发模块检测体温。实物测试表明，本次设计的门禁监测系统具有操作监简单、保密性强、防止密码被不法分子试错打开的优势。

Abstract
At present, with the development of science and technology, people’s living standards have been greatly improved, making people pay more and more attention to personal property and personal safety, the design of a single-chip based access control controller design, mainly to solve the current majority of users use the password lock in the input password lock was stolen by others, Or someone enters the password multiple times to steal the user’s password, causing property damage to the user.In order to prevent the password from being opened by criminals by trial and error, this design takes STM32 as the main control chip, uses the calculation and control function of the single chip microcomputer, and uses RFID to open the door by swiping-card, displays the student name, class, student number and other information through OLED, and detects the body temperature through the non-contact infrared trigger module. The physical test shows that the design of the access control monitoring system has the advantages of simple operation supervision, strong confidentiality, and preventing passwords from being opened by criminals.
