1、電氣控制技術(shù)與plc課程設(shè)計(jì)課程設(shè)計(jì)報(bào)告彩燈廣告屏的plc控制學(xué)院： 信息工程學(xué)院班級： 08建筑設(shè)施智能技術(shù)一班姓名： 崔興 （2008551425） 陸建朋（2008551428） 李杰 （2008551423） 指導(dǎo)老師：張仲模完成時(shí)間：2011年6月20日 一、引言 （一）摘要：本次課程設(shè)計(jì)主要目的是掌握可編程序控制器（plc）的基本工作原理、指令系統(tǒng)、硬件連接，學(xué)會(huì)使用可編程序控制器的基本方法，鍛煉plc編程能力，學(xué)會(huì)用plc解決電氣控制問題。本次課程設(shè)計(jì)我們選的題目是彩燈廣告屏的plc控制。要求編寫plc程序控制彩燈按一定要求亮滅。二、課程設(shè)計(jì)要求1. 設(shè)計(jì)任務(wù)：用plc控制一個(gè)彩

2、燈廣告屏。2. 控制要求 廣告屏中間有8根彩燈管，編號18，啟動(dòng)后，點(diǎn)亮的順序?yàn)?號依次到8號，間隔2s，全亮10s后，按8號到1號順序開始熄滅，間隔1s。全部熄滅后，等待2s，再開始一個(gè)循環(huán)。 廣告屏周圍安裝6組燈，給它編號。啟動(dòng)后，按照16的順序隔2s依次點(diǎn)亮。全亮20s，然后依次熄滅。全熄滅5s后，下一個(gè)循環(huán)從6到1號，隔2s依次點(diǎn)亮。然后開始新的循環(huán) 可以2組同時(shí)工作，也可以單獨(dú)工作。3. 設(shè)計(jì)內(nèi)容：1）計(jì)算輸入輸出點(diǎn)，編寫i/o對應(yīng)表及內(nèi)部元件使用表；2). 編寫plc控制程序；要求可以實(shí)現(xiàn)單步、單周期及連續(xù)工作3種操作方式。3）完成實(shí)驗(yàn)所需要的硬件接線；4）利用實(shí)驗(yàn)臺上的開關(guān)、按鈕

3、、小指示燈等，模擬演示其工作過程；5）完成課程設(shè)計(jì)報(bào)告。三、課程設(shè)計(jì)內(nèi)容1、設(shè)計(jì)過程和有關(guān)說明： 根據(jù)要求要實(shí)現(xiàn)單步，單周期，連續(xù)工作，并且能分組進(jìn)行單獨(dú)工作，加上啟動(dòng)停止，共設(shè)置了8個(gè)按鈕。輸出由q0.0-q0.7表示廣告屏中間的8根彩燈管。q1.0-q1.5表示廣告屏周圍的6組燈。（1）i o對應(yīng)表及內(nèi)部元件使用表如下：輸入表序號名稱輸入點(diǎn)序號名稱輸入點(diǎn)1啟動(dòng)i0.052組單獨(dú)運(yùn)行i0.42停止i0.161組單獨(dú)運(yùn)行i0.53單步開關(guān)i0.27兩組同時(shí)運(yùn)行i0.64連續(xù)單周期i0.38單步按鈕i0.7輸出表序號名稱輸出點(diǎn)序號名稱輸出點(diǎn)1一組1號q0.08一組8號q0.72一組2號q0.19

5、時(shí)間控制要求，對m0.1進(jìn)行控制就能達(dá)到單步，單周期和亮滅時(shí)間的控制目的。2、plc程序如下： 四、設(shè)計(jì)心得及程序調(diào)試過程1，設(shè)計(jì)過程設(shè)計(jì)過程中上網(wǎng)查閱了相關(guān)資料，確定了以移位寄存器為主要邏輯手段，以控制秒脈沖來實(shí)現(xiàn)各種控制要求。我們根據(jù)實(shí)際要求，分析只要做出一組燈，第第二組燈也是同樣的邏輯，然后我們先沒有考慮功能的實(shí)現(xiàn)，只對一組燈的邏輯進(jìn)行了一個(gè)簡單的實(shí)現(xiàn)。經(jīng)過對單周期，單步概念的理解，進(jìn)而做出了相應(yīng)的功能。最后整體在實(shí)驗(yàn)臺上操作以后進(jìn)行了進(jìn)一步的改進(jìn)，最終實(shí)現(xiàn)了所要求的效果。2，設(shè)計(jì)心得崔興：本次課程設(shè)計(jì)，在實(shí)驗(yàn)室待了幾天，雖然plc的知識是上個(gè)學(xué)期學(xué)習(xí)的，不過翻翻書以后大部分都記起來了，

6、先是對課程設(shè)計(jì)的要求做了一個(gè)簡單的分析，然后是初步構(gòu)思了一個(gè)簡單邏輯程序，單純的實(shí)現(xiàn)了燈的亮滅順序，而后在進(jìn)一步設(shè)計(jì)功能時(shí)，經(jīng)過多番討論終于設(shè)計(jì)出比較合理的方案。然后再反復(fù)的調(diào)試，最終成功。實(shí)驗(yàn)室待的幾天，感覺自己學(xué)的東西總算有些用途，同時(shí)我還跟其他組做其他課題的同學(xué)討論了他們的程序，學(xué)到了更多的東西。不過，拿我們寫的程序跟現(xiàn)實(shí)生活中的設(shè)計(jì)要求來比較之后，又發(fā)覺還有更多需要學(xué)習(xí)的地方?？偟膩碚f，這次設(shè)計(jì)讓我對理論和實(shí)際有了一個(gè)比較和認(rèn)識，也讓我知道，要想明白更多事情，必須不斷的把理論放在實(shí)踐中去。陸建朋：兩周的課程設(shè)計(jì)結(jié)束了，在這次的課程設(shè)計(jì)中不僅檢驗(yàn)了我所學(xué)習(xí)的知識，也培養(yǎng)了我如何去把握一件

7、事情，如何去做一件事情，又如何完成一件事情。在和小組成員的合作中，我收獲頗豐。我懂得了每個(gè)人都可以做得更加好，如果能夠在和他人合作的過程中充分發(fā)揮自己。 課程設(shè)計(jì)是我們專業(yè)課程知識綜合應(yīng)用的實(shí)踐訓(xùn)練，著是我們邁向社會(huì)，從事職業(yè)工作前一個(gè)必不少的過程”千里之行始于足下”，通過這次課程設(shè)計(jì)，我深深體會(huì)到這句千古名言的真正含義我今天認(rèn)真的進(jìn)行課程設(shè)計(jì)，學(xué)會(huì)腳踏實(shí)地邁開這一步，就是為明天能穩(wěn)健地在社會(huì)大潮中奔跑打下堅(jiān)實(shí)的基礎(chǔ)通過這次plc彩燈設(shè)計(jì)，本人在多方面都有所提高。通過這次設(shè)計(jì)，綜合運(yùn)用本專業(yè)所學(xué)課程的理論和生產(chǎn)實(shí)際知識進(jìn)行彩燈循環(huán)設(shè)計(jì)工作的實(shí)際訓(xùn)練從而培養(yǎng)和提高學(xué)生獨(dú)立工作能力，鞏固與擴(kuò)充了p

9、的幫助和支持，讓我感受到同學(xué)的友誼。 由于本人的設(shè)計(jì)能力有限，在設(shè)計(jì)過程中難免出現(xiàn)錯(cuò)誤，懇請老師們多多指教,我十分樂意接受你們的批評與指正，本人將萬分感謝。李杰：通過這次對彩燈循環(huán)點(diǎn)亮的plc控制，讓我了解了plc梯形圖、指令表、外部接線圖有了更好的了解，也讓我了解了關(guān)于plc設(shè)計(jì)原理。有很多設(shè)計(jì)理念來源于實(shí)際，從中找出最適合的設(shè)計(jì)方法。 本次課程設(shè)計(jì)脫離不了集體的力量，遇到問題和同學(xué)互相討論交流。多和同學(xué)討論。我們在做課程設(shè)計(jì)的過程中要不停的討論問題，這樣，我們可以盡可能的統(tǒng)一思想，這樣就不會(huì)使自己在做的過程中沒有方向，并且這樣也是為了方便最后設(shè)計(jì)和在一起。討論不僅是一些思想的問題，還可以深

10、入的討論一些技術(shù)上的問題，這樣可以使自己的處理問題要快一些，少走彎路。多改變自己設(shè)計(jì)的方法，在設(shè)計(jì)的過程中最好要不停的改善自己解決問題的方法，這樣可以方便自己解決問題 現(xiàn)在整個(gè)設(shè)計(jì)基本完成，過程中出現(xiàn)了一些問題，例如延遲不是蠻準(zhǔn)確，電路設(shè)計(jì)的不是蠻完善。我想只有我們在實(shí)踐中多總結(jié)，多思考，才能真正地做到學(xué)以致用！才能達(dá)到學(xué)習(xí)的真正目的！ag an employment tribunal claiemployment tribunals sort out disagreements between employers and employees. you may need to make a c
