簡介：基于AT89S52單片機(jī)溫度控制系統(tǒng)設(shè)計(jì)2012年5月工程及其自動化0806班姓名后學(xué)號200I摘要在工業(yè)生產(chǎn)過程中，有些設(shè)備需要嚴(yán)格要求現(xiàn)場環(huán)境的標(biāo)準(zhǔn)性和可行性。溫度是一個非常重要的物理量，溫度控制失誤就可能引起生產(chǎn)安全、產(chǎn)品質(zhì)量、產(chǎn)品產(chǎn)量等一系列問題，因此對溫度的檢測的意義很重要。無線傳輸是一種將有效數(shù)據(jù)傳輸至遠(yuǎn)方的一種有效方法，所以使用無線傳輸?shù)臏y溫系統(tǒng)可以對生產(chǎn)環(huán)境的溫度進(jìn)行無線采集并且能夠使操作員可以遠(yuǎn)距離實(shí)時了解被測現(xiàn)場的溫度變化情況。本設(shè)計(jì)以AT89S52單片機(jī)為核心的溫度控制系統(tǒng)，溫度信號由溫度芯片DS18B20采集，并以數(shù)字信號的方式傳送給單片機(jī)，在由單片機(jī)控制NRF905進(jìn)行數(shù)據(jù)的無線傳輸至另一個單片機(jī)，通過顯示及過限報警，然后使用紅外控制器調(diào)節(jié)模擬空調(diào)，達(dá)到規(guī)定溫度后自動解除警報。文中介紹了該控制系統(tǒng)的硬件部分、包括溫度采集電路、溫度控制電路、無線通信電路和一些接口電路。單片機(jī)通過對信號進(jìn)行相應(yīng)處理，從而實(shí)現(xiàn)溫度控制的目的。文中還介紹了軟件設(shè)計(jì)部分。關(guān)鍵詞單片機(jī)無線通信芯片溫度芯片溫度控制

簡介：畢業(yè)設(shè)計(jì)（論文）I單片機(jī)控制的單片機(jī)控制的PWM直流電機(jī)調(diào)速系統(tǒng)設(shè)計(jì)直流電機(jī)調(diào)速系統(tǒng)設(shè)計(jì)摘要直流電機(jī)是人類最早發(fā)明和應(yīng)用的一種電機(jī)。隨著時代的發(fā)展，數(shù)字電子技術(shù)已經(jīng)普及到我們生活、工作、科研各個領(lǐng)域。并且在各類機(jī)電系統(tǒng)中，由于直流電機(jī)具有良好的啟動、制動和調(diào)速性能，直流電機(jī)調(diào)速系統(tǒng)已廣泛應(yīng)用于工業(yè)、航天領(lǐng)域的各個方面，最常用的直流技術(shù)是脈寬調(diào)制（PWM）直流調(diào)速技術(shù)，具有調(diào)速精度高，響應(yīng)速度快，調(diào)速范圍寬和損耗低的特點(diǎn)。而利用計(jì)算機(jī)數(shù)字控制也成了直流調(diào)速的一種手段，數(shù)字控制系統(tǒng)硬件電路的標(biāo)準(zhǔn)化程度高，控制軟件能夠進(jìn)行復(fù)雜運(yùn)算，可以實(shí)現(xiàn)不同于一般線性調(diào)節(jié)的最優(yōu)化、自適應(yīng)、非線性、智能化等控制規(guī)律。本設(shè)計(jì)主要介紹了使用微控制器AT89S51的直流電機(jī)調(diào)速系統(tǒng)。論文主要介紹了直流電機(jī)調(diào)速系統(tǒng)的意義、基于單片機(jī)控制的PWM直流電機(jī)調(diào)速方法和PWM基本工作原理以及實(shí)現(xiàn)方法，通過對占空比的計(jì)算達(dá)到精確調(diào)速的目的。主電路主要采用四個小鍵盤控制AT89S51單片機(jī)，將數(shù)據(jù)傳輸給單片機(jī)并產(chǎn)生脈寬調(diào)制信號，然后通過電機(jī)驅(qū)動芯片L298對小型直流電機(jī)進(jìn)行控制。本設(shè)計(jì)還附加了由霍爾開關(guān)CS3020、AT89S51單片機(jī)、74LS47七段數(shù)碼管譯碼芯片和四位LED構(gòu)成轉(zhuǎn)速檢測顯示電路。通過按鍵的調(diào)試可以實(shí)現(xiàn)控制直流電機(jī)啟動、停止、方向和速度。設(shè)計(jì)的整個系統(tǒng)，采用了大量的集成電路模塊，大大簡化了硬件電路，提高了系統(tǒng)的可靠性和穩(wěn)定性。最后在軟件方面，介紹了主程序、鍵盤掃描子程序、PWM信號發(fā)生程序、測速子程序和顯示子程序的編寫思路以及具體的程序?qū)崿F(xiàn)。關(guān)鍵詞單片機(jī)AT89S51；直流電機(jī)；脈寬調(diào)制；轉(zhuǎn)速檢測畢業(yè)設(shè)計(jì)（論文）IIIOFTHEWHOLESYSTEMHASBEENUSEDTHEMASSIVEINTEGRATEDCIRCUITMODULE,WHICHCANBEUSEDTOSIMPLIFYTHEHARDWAREELECTRICCIRCUITGREATLY,IMPROVETHESYSTEMRELIABILITY,STABILITYFINALLYINTHESOFTWARE,THEMAINROUTINE,KEYBOARDSCANSUBROUTINE,PWMSIGNALPRODUCINGSUBROUTINE,VELOCITYMEASUREMENTSUBROUTINEANDTHEDEMONSTRATIONSUBROUTINECOMPILATIONASWELLASTHESPECIFICPROGRAMAREINTRODUCEDKEYWORDSSCMAT89S51DCMOTORPWMMEASUREMENTOFROTATINGSPEED

簡介：摘要摘要自計(jì)算機(jī)問世以來，單片機(jī)技術(shù)在社會各領(lǐng)域中得到了廣泛的應(yīng)用。在流水燈控制系統(tǒng)中，單片機(jī)更是取代了由齒輪調(diào)節(jié)延遲時間的舊式市發(fā)展速度，成為日后此系統(tǒng)中的核心部分。由于單片機(jī)具有一些突出的優(yōu)點(diǎn)體積小、重量輕、電源單一、功耗低；功能強(qiáng)、價格低；數(shù)據(jù)大都在單片機(jī)內(nèi)部傳送，運(yùn)行速度快、抗干擾能力強(qiáng)、可靠性高，所以單片機(jī)被廣泛的應(yīng)用于測控系統(tǒng)、數(shù)據(jù)采集、智能儀器儀表、機(jī)電一體化產(chǎn)品、智能接口、計(jì)算機(jī)通信以及單片機(jī)的多級系統(tǒng)等領(lǐng)域。本文主要講的是單片機(jī)，課題名稱為多按鍵花樣流水燈，它使我們學(xué)會了如何使用單片機(jī)控制我們?nèi)粘Ｉ钪械亩嘣O(shè)備設(shè)施的應(yīng)用。通過本課題的設(shè)計(jì)以后，使我了解到了單片機(jī)的許多方面的應(yīng)用。關(guān)鍵詞關(guān)鍵詞單片機(jī)、可編程控制器、交通型號燈、可靠性高。廠、學(xué)校及企事業(yè)單位大規(guī)模地興起。本設(shè)計(jì)用AT89C51單片機(jī)自制了一款簡易的花樣流水燈，介紹了其硬件電路及軟件編程方法，在實(shí)踐中體驗(yàn)單片機(jī)的自動控制功能。該設(shè)計(jì)具有實(shí)際意義，可以在廣告業(yè)、媒體宣傳、裝飾業(yè)等領(lǐng)域得到廣泛應(yīng)用。學(xué)習(xí)單片機(jī)的最有效方法就是理論與實(shí)踐并重，現(xiàn)在我把單片機(jī)流水燈設(shè)計(jì)作為一個課程設(shè)計(jì)，需要更深的去了解單片機(jī)的很多功能，努力的去查找資料。本課題將以發(fā)光二極管作為發(fā)光器件，用單片機(jī)自動控制，實(shí)現(xiàn)一個簡易的花樣流水燈設(shè)計(jì)。1相關(guān)元件及電路設(shè)計(jì)11AT89C51芯片功能特性及應(yīng)用單片機(jī)在我們的日常生活和工作中無處不在、無處不有家用電器中的電子表、洗衣機(jī)、電飯褒、豆?jié){機(jī)、電子秤；住宅小區(qū)的監(jiān)控系統(tǒng)、電梯智能化控制系統(tǒng)；汽車電子設(shè)備中的ABS、GPS、ESP、TPMS；醫(yī)用設(shè)備中的呼吸機(jī)，各種分析儀，監(jiān)護(hù)儀，病床呼叫系統(tǒng)；公交汽車、地鐵站的IC卡讀卡機(jī)、滾動顯示車次和時間的LED點(diǎn)陣顯示屏；電腦的外設(shè)，如鍵盤、鼠標(biāo)、光驅(qū)、打印機(jī)、復(fù)印件、傳真機(jī)、調(diào)制解調(diào)器；計(jì)算機(jī)網(wǎng)絡(luò)的通訊設(shè)備；智能化儀表中的萬用表，示波器，邏輯分析儀；工廠流水線的智能化管理系統(tǒng)，成套設(shè)備中關(guān)鍵工作點(diǎn)的分布式監(jiān)控系統(tǒng)；導(dǎo)彈的導(dǎo)航裝置，飛機(jī)上的各種儀表等等。有資料表明2007年全球單片機(jī)的產(chǎn)值達(dá)到151億美元，我國單片機(jī)的銷售額達(dá)到400億元人民幣，我國每年單片機(jī)的需求量達(dá)50至60億片，是全球單片機(jī)的最大市場。可以說單片機(jī)已經(jīng)滲透到了我們生活的各個領(lǐng)域。在AT89C51芯片內(nèi)部有一個高增益反相放大器，用于構(gòu)成振蕩器。反相放大器的輸入端為引腳XTAL1，輸出端為引腳XTAL2，在芯片的外部通過這兩個引腳跨接晶體振蕩器和微調(diào)電容C1、C2形成反饋電路，可構(gòu)成穩(wěn)定的自激振蕩器，振蕩頻率通常是1212MHZ。若晶體振蕩器頻率高，則系統(tǒng)的時鐘頻率也高，單片機(jī)的運(yùn)行速度也就快
