摘要
为提升高校实验室的安全性和便利性,设计了一种智能化的门禁系统.运用单片机STC89C52作为控制器,采用红外测温传感器检测体温,通过键盘输入密码,单片机将储存的密码与输入密码进行对比,通过PWM算法控制门锁动作,同时将所测体温与密码比对结果进行显示.仿真实验结果表明,该系统可以实现密码开锁、人体测温等功能,测温平均相对误差为0.07％.该系统的成本低、操作方便、节省了人力资源,推进了线下实验课的安全展开.
Abstract
To enhance the safety and convenience of university laboratories,an intelligent access control system has been designed.This system utilizes the STC89C52 single-chip microcomputer as its controller,employs an infrared temperature sensor for body temperature detection,and allows password input through a keyboard.The single-chip microcomputer compares the stored password with the input password,controls the door lock action through a PWM algorithm,and simultaneously displays the measured body temperature and password comparison results.The simula-tion experimental results indicate that this system can achieve functions such as password unlocking and body temperature measurement,with an average relative error of 0.07％in temperature measurement.This system is cost-effective,easy to operate,saves human resources,and promotes the safe conduct of offline experimental classes.
