1、咸寧學(xué)院學(xué)士學(xué)位論文電子與信息工程學(xué)院本 科 畢 業(yè) 論 文論文題目 數(shù)字密碼鎖的設(shè)計 學(xué)生姓名 學(xué) 號 專 業(yè) 電子信息科學(xué)與技術(shù) 班 級 電信 指導(dǎo)教師 2010年5月3湖北科技學(xué)院學(xué)士學(xué)位論文摘 要基于atmega88v設(shè)計的數(shù)字密碼鎖是以atmega88v為核心控制電路，配以電源電路、復(fù)位電路、指示電路、報警電路、鍵盤電路等外圍電路，實(shí)現(xiàn)對密碼的輸入、識別、修改、存儲及輸入密碼錯誤時報警等功能。該系統(tǒng)中，atmega88v是輸入和輸出的聯(lián)系部件，它通過讀取從鍵盤輸入的數(shù)據(jù)并對存儲在單片機(jī)中的密碼進(jìn)行識別比較，判斷密碼是否輸入正確，并作出相應(yīng)的決定，指示報警器是否發(fā)出嗡鳴聲以及發(fā)光二極管

2、是否閃爍。這種密碼鎖以其安全性高、成本低、易操作等優(yōu)點(diǎn)受到越來越多人的歡迎。關(guān)鍵詞：密碼鎖；atmega88v；鍵盤；lcd顯示abstractthe core control circuit of digital code lock designed based on atmega88v is atmega88v,and together with the power circuit, reset circuit, indicating circuit, alarm circuit, keyboard and other peripheral circuits circuit it can

3、realize the function of input, identification, modification, storage of the password, and the alarm when inputting the wrong password. in the system, atmega88v is the link of input and output components, it can estimate whether the input password is right by identifying and comparing the data readin

4、g from the keyboard and the password stored in the microcontroller, and make the appropriate decision that whether the indicating alarm audible hum and the light diode blinking. because of its high security, low cost, easy operation, etc, this digital code lock is more and more popular. key words: d
