基于单片机的指纹识别报警系统的设计

基于单片机的指纹识别报警系统的设计(开题报告,论文15000字)
摘要
伴随现代社会科技的高速发展，传统的个人身份识别方式如同密码，口令，信物，暗号等等由于与个人身份的可分离性，变得越来越容易被假冒，伪造，盗用以及破解。这些老旧的手段已经不能满足社会以及家庭经济活动和安全防范的需求。指纹作为伴随人出生便拥有的特殊标志，代表的是一个人最特殊的特点，具有很强的稳定性和独特性。因此，基于指纹的识别技术氤氲而生。由于其可用性，安全性，成熟性，以及价格低等诸多优势，指纹识别技术将成为未来人体生理特征身份识别技术的主流之一，将会给我们的生活带来诸多安全与方便。
本次设计以STC89C52单片机作为核心模块，通过串口通信控制ZFM-60指纹模块实现录入，存储以及识别指纹数据的功能，并通过HS12864液晶屏显示指纹匹配的结果，辅以直流继电器与发光二极管，蜂鸣器等构成电路模拟开锁的动作以及对三次识别错误发出声光报警。本设计系统具有体积小巧，性价比高，检测速度快等优点。适合家庭以及单位选择使用。

The design of afingerprint identification alarm system based on single chip microcomputer
Abstract
Along with the rapid development of the science and technology in the modern society, the traditional way of personal identity such as passwords, tokens, sign and so on , Due to the separability of personal identity, becoming more and more easier to counterfeit, fake, theft and cracked. These old methods cannot satisfied the social and family economic activity and safety requirements. Fingerprints as a special sign accompany people are born with, is a representative of the person's unique features, it have very strong stability and uniqueness. Therefore, technology based on the fingerprint recognition was invented. Because of its availability，security, maturity, and low prices，fingerprint identification technology will become the mainstream of modern and future physical characteristics identification technology. Fingerprint identification technology will have many security and convenience to our life.
The design system using STC89C52 single-chip microcomputer as the core module, serial communication control ZFM-60 fingerprint module implements entry, storage, and identify the function of fingerprint data, and through the HS12864 LCD shows the result of fingerprint matching, supplemented by dc relay and light-emitting diode, the circuit simulation unlock buzzer action and to identify three times error alarm. This system has small volume, high cost performance, the transmission speed, the system is suitable for both families and companies.
