摘　　要
近年來，指紋識(shí)別技術(shù)在國(guó)內(nèi)外發(fā)展很快，由于其良好的安全性目前該技術(shù)已被廣泛應(yīng)用于生活和工作中。隨著成本的下降，指紋識(shí)別技術(shù)呈現(xiàn)全面推廣和普遍應(yīng)用的趨勢(shì)。
指紋識(shí)別技術(shù)是目前國(guó)際公認(rèn)的應(yīng)用廣泛、價(jià)格低廉、易用性高的生物人證技術(shù)。指紋只是人體皮膚的一小部分，但是它卻蘊(yùn)涵了大量的信息。皮膚的紋路在圖案斷點(diǎn)交叉點(diǎn)是個(gè)不相同的。醫(yī)學(xué)上已經(jīng)證明這些特征對(duì)于每個(gè)手指都是不同的，而且這些特征具有唯一性和永久性。因此我們就可以把一個(gè)人同他的指紋對(duì)應(yīng)起來，通過比較他的指紋特征和預(yù)先保存的指紋特征，就可以驗(yàn)證他的真實(shí)身份。
本設(shè)計(jì)開發(fā)了一款基于單片機(jī)的指紋識(shí)別電子密碼鎖系統(tǒng)。該系統(tǒng)以ATmeg16單片機(jī)作為模塊核心，通過串口通信控制ZAZ-010指紋模塊實(shí)現(xiàn)錄取指紋并存儲(chǔ)指紋數(shù)據(jù)，并通過HS12864-15C液晶顯示比對(duì)流程及比對(duì)結(jié)果，輔以直流繼電器與發(fā)光二極管模擬開鎖的動(dòng)作。本系統(tǒng)具有體積小、性價(jià)比高、傳輸速度快、適合家庭及單位使用。

ABSTRACT
In recent years, fingerprint identification technology has developed rapidly in China and abroad, because of its good security now that the technology has been widely used in daily life and work. With the decline in the cost of the fingerprint recognition technology and the comprehensive promotion and general trends should be.
Fingerprint recognition technology is a technology of biology-authentication widely used and legalized in international today because of its low-price and finer application. Fingerprint just is a small part of the skin, but it contains a great deal of information .The veins of the skin are different in pattern and cross point and break point. Medicine has proven that these characteristics are different for each finger and these characteristics are unique and permanent. So we can put a person's fingerprints correspond with him by comparing his fingerprint characteristics and pre-stored fingerprint features, you can verify his true identity.
The system design of fingerprint recognition electron password lock based on Single-chip microprocessor is developed in the thesis. The system ATmeg16 MCU as the core module, through the serial communication control ZAZ-010 fingerprint module for taking fingerprints and store fingerprint data and liquid crystal display by HS12864-15C ratio than on the processes and results, supported by simulation of DC relays and LEDs unlock action. The system is small, cost-effective, and fast and suitable for families and units.

Key Words：Single-chip microprocessor; fingerprint detection; LCD
