【正文】 JIU JIANG UNIVERSITY 畢 業(yè) 論 文 （ 設(shè) 計 ）題 目 基于單片機的數(shù)字電子鐘 英文題目 Digital clock based on MCU 院 系 電子工程學(xué)院 專 業(yè) 電子信息工程 姓 名 胡祥 年 級 2022 級（A112225） 指導(dǎo)教師 吳紅蓮 二零一四年十二月九江學(xué)院I摘要當(dāng)今社會數(shù)字鐘應(yīng)用非常普遍，像日常家用最普通的時鐘，用于計時和設(shè)置鬧鐘，雖然功能較少，但是卻是我們最重最實用的電子產(chǎn)品之一。這次我要做的就是這個雖然相對簡單但是卻十分具有意義的具有校準(zhǔn)時間和計時的數(shù)字電子鐘。由 MCS51 單片機作為數(shù)字電子鐘的核心控制器，數(shù)碼管作為顯示模塊，可以顯示我們需要的“時，分，秒”。按鍵作為調(diào)節(jié)時間的模塊，通過按鍵我們可以進行時間校準(zhǔn)，定時功能。講完硬件這個最基本最重要的東西之后，接下來我們講講軟件方面，軟件可以說是一個電子產(chǎn)品的靈魂，通過編程我們可以擴展更多的更實用的功能。像蘋果公司推出的第一款智能手表就是以電子鐘作為基礎(chǔ)再加入了更多編程。相信我也可以把基礎(chǔ)東西做的如此優(yōu)秀?！娟P(guān)鍵詞】MCS51，單片機，數(shù)碼管 AbstractDigital clock is widely used in today’s society,like the daily household most oridinary clock,it can be used for time and set the alarm,Although it is less functional,But it is our most heavy one of the most practical electronic is what I want to do this while the digital electronic clock with time calibrating and timing is relatively simple but very clock is the microcontroller MCS51 as the core ponent,digital tube as display module,it can shows“hours,minutes,seconds”.Key as the adjusting time module,through the button we can calibrate the hardware of the most basic and the most important thing,next we talk about the software,the software can be said to be a grateful electronic products of the soul,through software programming we can expand more practical Corp launched the rirst intelligent Appwatch is based on the electronic clock and adding more believe i can get things done so good foundation.[keywords] MCS51,MCU,Digital tube九江學(xué)院I摘 要 .............................................................IIABSTRACT...........................................................................................................................................II前 言 ...............................................................................................................................................II第 1 章 緒論 .....................................................................................................................................II 單片機的認(rèn)識 ...................................................................................................................II 單片機的發(fā)展史及趨勢 ...................................................................................................II第 2 章各個模塊介紹及作用 ...........................................................................................................II 8051 單片機模塊 ..............................................................................................................II 數(shù)碼管顯示模塊 ...............................................................................................................II 數(shù)碼管的介紹 .......................................................................................................II 多位數(shù)碼管顯示原理 ...........................................................................................II 電子鐘實現(xiàn)系統(tǒng)框圖 .......................................................................................................II 電子鐘系統(tǒng)原理圖 ...........................................................................................................II第 3 章軟件開發(fā) KEIL C51 的介紹 .................................................................................................II第 4 章硬件仿真 PROTUS 的介紹 .....................................................................................................II第 5 章硬件電路設(shè)計 .......................................................................................................................II 電源電路 ...........................................................................................................................II 按鍵電路 ..........................................................................................................................III 復(fù)位電路 ..............................................................................................................III 調(diào)節(jié)電路 ..............................................................................................................III 數(shù)碼管顯示電路 ..............................................................................................................III 時鐘電路 ..........................................................................................................................III第 6 章系統(tǒng)軟件設(shè)計 ......................................................................................................................III 程序流程圖 .......................................................................................................................III 電子鐘系統(tǒng)主程序流程圖 ..................................................................................III 電子鐘系統(tǒng)中斷程序流程圖 .........................................
