题 目: - I -基于单片机的智能指纹门禁系统的设计电气自动化学院摘 要随着社会的发展,人们安全意识不断加强,但是由于工作和生活的原因,在家的时间不断减少,所以社区和住房安全问题困扰这大家。一般的社区很少有门卫或者安全的大门可以随便出入,或者门禁的采用普通的锁具安全性低,所以我想由此设计出一款安全性高,性价比高,具有大规模普及的智能指纹门禁系统。指纹识别技术是一门基于图像处理和计算机技术发展而来的学科,随着指纹技术的不断发展,逐渐变得价格低廉并且准确性高,具有大规模普遍的价值。指纹作为一种生物识别特征,它具有唯一性,不可更改的特性,每个人的指纹都各不相同并且不会随着时间的变化而变化,也不容易被盗取。本次设计以单片机为基础,采用指纹识别模块,液晶屏,蜂鸣器,矩阵键盘,电源,时钟电路,电磁锁等构成。设计原理为:通过指纹识别模块实现指纹的录入,对比以及删除,由模块通过串口将结果上传到单片机,然后由单片机控制门禁系统的开关动作。最终完成的系统实物可以通过指纹和密码两种方法打开门禁,当指纹开锁不可行的时候,可使用密码开锁,系统具有录入和删除指纹模板,更改管理员密码等功能。本次设计的智能指纹门禁系统与如今市面上的普通锁具相比,具有安全性高,操作简单,性价比高,可大规模普遍的特点。可以广泛的应在社区门卫,家庭门锁等方面。- II -关键词: 单片机;指纹识别;指纹锁;液晶屏AbstractWith the development of society, people's awareness of safety has been continuously strengthened, but due to work and life reasons, the time at home has been declining, so community and housing safety issues have plagued everyone. In general communities, there are few door guards or secure gates that can be easily accessed, or the use of ordinary locks for access control has low security, so I want to design a smart fingerprint access control with high security, high cost performance, and mass popularity. system.Fingerprint recognition technology is a discipline based on the development of image processing and computer technology. With the continuous development of fingerprint technology, it has grad...
