基于生物识别技术的门禁系统
摘要
随着科技的进步,人们对门禁系统的安全性要求越来越高,而与此同时一些传统的门禁技术已经不能满足当前社会对门禁安全性的要求,基于生物识别的指纹识别技术的出现弥补了传统身份验证设备的不足,每个人的包括指纹在内的皮肤纹路在图案、断点和交叉点上各不相同,是唯一的,并且终生不变。依靠这种唯一性和稳定性,指纹识别与电子信息技术结合的指纹门禁系统具有可靠性高、不可复制、操作简易等特点。
本文利用指纹模块、单片机、门锁驱动、LCD显示构成的门禁系统,可实现指纹开门、指纹录入、指纹管理等功能,在实际应用中与传统设备相比具有很大优越性,传统的机械锁如有较多用户使用,就需要有很多钥匙给每个用户,这样即对安全性造成威胁同时钥匙的管理也难度很大,而指纹锁完全没用这种问题,指纹具有唯一性,当取消某人进入门禁资格时删除指纹库中该人信息即可,本课题采用PIC16F877单片机作为主控器与指纹模块串行通信同时驱动LCD与门锁驱动实现了基于指纹识别门禁系统。

Abstract
With the progress of science and technology, people’ requirement for access security system has e increasingly demanding. While at the same time, some traditional access technology cannot satisfy the requirements of social security. The appearance of fingerprint identification based on biological recognition makes up the shortage of the traditional authentication devices. Everyone’ skin texture, including fingerprint, differ in pattern, breakpoints and intersection which are unique and lifelong unchangeable. With this uniqueness and stability, fingerprint door system featuring the integration of fingerprint identification and electronic information technology has the feature of higher reliability, unsociably and simple operation, etc.
By using fingerprint module, SCM, door locks, LCD display driver of entrance guard system, fingerprint door, fingerprints, fingerprint management function can be achieved. It has great advantages in actual pared to the traditional equipment. When the traditional mechanical lock is used by more consumers, it needs to have many keys to give each user, which will threaten the security and increase the difficulty of management. While fingerprint locks do not have this kind of problems because of fingerprint’ uniqueness. Someone’ permissio
