摘要
随着信息技术的快速发展,传统的身份识别方式(诸如密码、证件等)已经不能满足不断增加的安全需要,身份识别已经成为信息安全领域所面临的一个难题。作为一种飞速发展的技术,指纹识别已经在刑侦领域大显身手,在身份认证等民用领域,这项技术也具有广阔的应用空间。恰当地把指纹识别系统应用到门禁锁上去,能更有效地实现门锁产品智能化和防盗的目标。
论文采用具有较大存储力,低功耗,高性能的8位AT89C51单片机和独立的指纹识别模块SM-2B,结合指纹识别的应用情况,以指纹算法在门禁锁上实现的思想为指导,运用成熟的指纹识别算法和单片机技术,设计和实现了一个高性能、低成本、低功耗、识别速度快的指纹锁系统。该系统具有指纹开锁,指纹录入,指纹删除,应急密码开锁(指纹受损、指纹被盗、主人未在家允许客人进入),智能报警,电压监测等功能,所涉及的技术成熟,操作简单方便,实用性很强,具有广泛的使用价值和应用前景。

ABSTRACT
With the development of electronic information technology, the traditional identification technology, such as password and certificate, can not satisfy the need of safety. Identification has e much more serious than before. The fingerprint recognition technology is developing very fast and used in many fields. As a rapidly developing technology, fingerprint identification has been shown their talents in the field of criminal investigation, and in the field of authentication, the technology also has broad application space.
In this paper, combined with the application of fingerprint recognition, fingerprint algorithm in order to lock in access control to achieve as a guide, the use of sophisticated algorithms and embedded systems fingerprint technology, design and realization of a high-performance, low-cost, low power consumption, to identify the lock system is fast. In this paper, the following aspects from the research work carried out: for the analysis of biometric technology, fingerprint identification system at home and abroad prospect of development and market demand, the application of fingerprint recognition algorithm and the conditions of the existing hardware and software, system design, a Embedded lock program, which includes hardware and software platform for the design of structures to achieve.
Keywords: fingerprint lock, single-chip puterAT 89C51, fingerprint identification
