摘要

單片機(jī)以其體積小、編程靈活、控制功能強(qiáng)大、價(jià)格低廉等特點(diǎn)被廣泛應(yīng)用在各種電子電器產(chǎn)品中。單片機(jī)技術(shù)的出現(xiàn)和發(fā)展帶來了電子技術(shù)和控制領(lǐng)域的一場(chǎng)革命。

單片機(jī)課程作為職業(yè)院校電子信息類專業(yè)一門重要的基礎(chǔ)課程，它既是一門很有實(shí)用價(jià)值、實(shí)踐性很強(qiáng)且很有趣味性的課程，同時(shí)它又是一門集硬件電路設(shè)計(jì)與軟件編程于一體的學(xué)科，既要求我們有較好的電工電子技術(shù)基礎(chǔ)知識(shí)，又要求有一定的邏輯思維和軟件開發(fā)（編程）能力。通過近幾年對(duì)單片機(jī)的學(xué)習(xí)，我已掌握單片機(jī)的基本知識(shí)，并具備了單片機(jī)應(yīng)用系統(tǒng)的初步開發(fā)能力。即將畢業(yè)之際，我運(yùn)用我所掌握的單片機(jī)知識(shí)設(shè)計(jì)和制作了一個(gè)基于51單片機(jī)的可調(diào)數(shù)碼日歷鐘，這既是對(duì)我所學(xué)知識(shí)的總結(jié)與高度概括，同時(shí)也將自己所掌握的知識(shí)與實(shí)際應(yīng)用結(jié)合起來，進(jìn)一步提高工程實(shí)踐能力。

數(shù)碼日歷鐘是實(shí)際生活中應(yīng)用較多的一個(gè)電子計(jì)時(shí)裝置，可供人們查詢?nèi)掌凇⑿瞧诩罢莆諘r(shí)間。本文首先從數(shù)碼日歷鐘的功能要求入手，對(duì)設(shè)計(jì)任務(wù)進(jìn)行了分析，并將任務(wù)分解為若干個(gè)模塊，提出在設(shè)計(jì)與制作過程中要用到的相關(guān)知識(shí)點(diǎn)，給出了本設(shè)計(jì)的硬件電路及軟件流程，還給出了部分模塊的源程序代碼。本設(shè)計(jì)經(jīng)過多次調(diào)試運(yùn)行無誤，最終提交出一個(gè)完整的應(yīng)用系統(tǒng)產(chǎn)品。

本次畢業(yè)設(shè)計(jì)的數(shù)碼日歷鐘能在12864液晶屏上顯示出年月日時(shí)分秒以及星期幾，還能顯示當(dāng)前環(huán)境溫度，并能通過按鍵調(diào)整日期和時(shí)間，在調(diào)整日期的同時(shí)通過相應(yīng)算法自動(dòng)實(shí)現(xiàn)星期幾的調(diào)整，而且無論是否閏年、任何月份，當(dāng)日期調(diào)整時(shí)都保證不會(huì)出現(xiàn)非法日期。數(shù)碼日歷鐘是一個(gè)非常實(shí)用的設(shè)計(jì)與制作，成本低廉，如能進(jìn)一步完善，具有一定的推廣使用價(jià)值。

本設(shè)計(jì)任務(wù)比較復(fù)雜，要考慮的問題很多，C語言的模塊化程序設(shè)計(jì)思想較好地解決了這個(gè)問題，故本設(shè)計(jì)任務(wù)采用C語言編程。

1、概述

1.1畢業(yè)設(shè)計(jì)的選題背景及制作意義

1.1.1畢業(yè)設(shè)計(jì)的選題背景

單片機(jī)以其體積小、編程靈活、控制功能強(qiáng)大、價(jià)格低廉等特點(diǎn)被廣泛地應(yīng)用在各種電子電器產(chǎn)品中。單片機(jī)技術(shù)的出現(xiàn)和發(fā)展帶來了電子技術(shù)和控制領(lǐng)域的一場(chǎng)革命。

單片機(jī)課程作為職業(yè)院校電子信息類專業(yè)一門重要的基礎(chǔ)課程，它既是一門很有實(shí)用價(jià)值、實(shí)踐性很強(qiáng)且很有趣味性的課程，同時(shí)它又是一門集硬件電路設(shè)計(jì)與軟件編程于一體的學(xué)科，既要求我們有較好的電工電子技術(shù)基礎(chǔ)知識(shí)，又要求有一定的邏輯思維和軟件開發(fā)（編程）能力。通過近幾年對(duì)單片機(jī)的學(xué)習(xí)，我已掌握單片機(jī)的基本知識(shí)，并具備了單片機(jī)應(yīng)用系統(tǒng)的初步開發(fā)能力。即將畢業(yè)之際，為了將自己所掌握的知識(shí)與實(shí)際應(yīng)用結(jié)合起來，進(jìn)一步提高工程實(shí)踐能力，同時(shí)也對(duì)自己所學(xué)知識(shí)作以總結(jié)及高度概括向老師匯報(bào)，我決定將我的畢業(yè)設(shè)計(jì)課題選作基于51單片機(jī)的可調(diào)數(shù)碼日歷鐘的設(shè)計(jì)與制作，并以此向老師作畢業(yè)匯報(bào)。

1.1.2畢業(yè)設(shè)計(jì)的制作意義

數(shù)碼日歷鐘是實(shí)際生活中應(yīng)用較多的一個(gè)電子計(jì)時(shí)產(chǎn)品，廣泛地應(yīng)用在酒店、賓館、車站、家庭及辦公室中，可供人們查詢?nèi)掌凇⑿瞧?，掌握?dāng)前時(shí)間及環(huán)境溫度。

在上述背景下，需要我運(yùn)用近幾年在學(xué)校學(xué)到的單片機(jī)知識(shí)及開發(fā)技巧設(shè)計(jì)和制作出一個(gè)功能完善的可調(diào)數(shù)碼日歷鐘。通過這個(gè)設(shè)計(jì)的制作，必將進(jìn)一步提高我的工程實(shí)踐能力和單片機(jī)應(yīng)用系統(tǒng)開發(fā)能力，將我所學(xué)到的理論知識(shí)與實(shí)際應(yīng)用結(jié)合起來，做到理論與實(shí)踐相結(jié)合，同時(shí)也能對(duì)我高職階段所學(xué)知識(shí)作以梳理和總結(jié)。這是一個(gè)非常實(shí)用的設(shè)計(jì)與制作，成本低廉，若將它稍加改進(jìn)安裝在鏡框或其它工藝品中，則更加實(shí)用。如能進(jìn)一步完善其功能，具有一定的實(shí)際推廣使用價(jià)值。

1.2數(shù)碼日歷鐘的功能要求

本設(shè)計(jì)制作出來的數(shù)碼日歷鐘要求能在12864液晶顯示屏上顯示出年月日及對(duì)應(yīng)的星期幾，當(dāng)前時(shí)間及環(huán)境。而且要求日期和時(shí)間可通過按鍵調(diào)整，當(dāng)日期調(diào)整時(shí)，通過相應(yīng)算法自動(dòng)實(shí)現(xiàn)星期幾的調(diào)整，無論是否閏年、任何月份，當(dāng)日

摘要

隨著單片機(jī)技術(shù)的飛速發(fā)展，在其推動(dòng)下，現(xiàn)代的電子產(chǎn)品幾乎滲透到了社會(huì)的各個(gè)領(lǐng)域，有力地推動(dòng)了社會(huì)生產(chǎn)力的發(fā)展和社會(huì)信息化程度的提高，同時(shí)也使現(xiàn)代電子產(chǎn)品性能進(jìn)一步提高。

時(shí)間對(duì)于人們來說總是那么的寶貴，可以說時(shí)間和金錢是劃上了等號(hào)。準(zhǔn)確的掌握時(shí)間和分配時(shí)間對(duì)人們來說至關(guān)重要。因此采用單片機(jī)為主的數(shù)碼管為顯示器的電子時(shí)鐘就體現(xiàn)出了很大的優(yōu)勢(shì)。電子鐘的設(shè)計(jì)方法有很多種，但利用單片機(jī)制作的電子時(shí)鐘更具有編程靈活、便于電子功能的擴(kuò)充、精確度高、便于攜帶、顯示直觀等特點(diǎn)。

通過利用MCS-51單片機(jī)內(nèi)部的定時(shí)器/計(jì)數(shù)器功能來實(shí)現(xiàn)電子時(shí)鐘的計(jì)時(shí)方法。主要由AT89S51芯片和LED數(shù)碼顯示管為核心，構(gòu)成了一個(gè)單片機(jī)電子時(shí)鐘。
