文档介绍：身体识别系统的研究(硬件)
摘要
随着生活方式的改变,现在越来越多的场合需要通过身份识,从而来验证一个人是否可以进行某个操作,或者记录下某个人的操作记录等。由于应用上的实用性及可行性,所以指纹识别相关技术制成的系统,成为现代生活中使用最可靠、最流行、最广泛的个人身份认证方式之一,并且己在社会生活的方方面面得到广泛应用。指纹识别技术之所以能被广泛应用在生活各个方面,这也主要归功于指纹的独特性:指纹是独一无二的,世界上几本不存在相同的指纹;另外,指纹样本相对易于采集、便于开发、难以伪造、实用性强,并且可以利用一个人的多个指纹一系列的指令系统,以此来提高系统的安全性;加之,指纹与人的个体是密不可分的,难以造假,几本不会出现被盗用的情况;以上得天独厚的特点做指纹识别技术受到大众的广泛欢迎。近几年来,指纹相关产品在当今社会中的应用已日益普遍,人们的新时代生活方式正在因为指纹技术的发展而日益更新着。本文介绍了一个身份识别系统,该系统核心技术是指纹识别技术,通过指纹识别设计的一个考勤系统,系统中有查询学号,查询时间,指纹录入,指纹采集等众多功能。本文主要分别通过系统各个模块,如:主控制单片机芯片,存储模块,指纹模块,LCD12864模块、时钟模块等,外加上位机的实现,来介绍该身份识别系统技术要点,是如何实现身份识别的整个完整的系统工作流程。另外,本文也介绍了整个系统的制作流程。

Research of physical identification system (hardware)
Abstract
Along with the change in lifestyle, now more and more occasions of identity is required, as proposed, so as to verify whether a person can perform an action, records or record the actions of one person, and so in many recognition way in the: as people face recognition, IC RF card recognition, password validation, Palm recognition, fingerprint recognition,, fingerprint recognition technology relative Yu other recognition method has many advantage, most important of is, fingerprint recognition technology has is high of practicality and the feasibility, so fingerprint recognition became current social most pop, and most convenient, and most reliable of identity recognition certification way one, and f in social life of aspects get widely identification technology has been widely used in all aspects of life, which is mainly due to the uniqueness of fingerprints: fingerprints are unique, the world does not exist on the same fingerprint;In addition, fingerprint samples are relatively easy to collect and facilitate the development, difficult to counterfeit, practicality, and can make use of multiple prints multiple passwords, thereby improving system security;In addition, fingerprints of individual is inextricably linked, it is difficult to fake, unauthorised us
