1、屆學(xué)生畢業(yè)論文(設(shè)計(jì))存檔編號(hào):江漢大學(xué)文理學(xué)院CollegeofArts&ScienceofJianghanUniversity畢業(yè)論文(設(shè)計(jì))論文題目基于plc的物料傳送系統(tǒng)設(shè)計(jì)Transmissionsystembasedonthedesignofmaterialsplc學(xué)部信息技術(shù)學(xué)部專業(yè)07自動(dòng)化姓名劉豪學(xué)號(hào)200706060111指導(dǎo)教師羅海庚2011年4月12日-28-摘要二十世紀(jì)九十年代以來,計(jì)算機(jī)的不斷發(fā)展引發(fā)了各個(gè)領(lǐng)域的革命性變革。隨著微處理器,計(jì)算機(jī)技術(shù)和數(shù)字通信技術(shù)的飛速發(fā)展,計(jì)算機(jī)控制已擴(kuò)展到幾乎所有的工業(yè)領(lǐng)域。現(xiàn)代社
2、會(huì)要求制造業(yè)對(duì)市場(chǎng)需求做出迅速的反應(yīng),生產(chǎn)出小批量多,品種,多規(guī)格,低成本和高質(zhì)量的產(chǎn)品。為滿足這一要求,生產(chǎn)設(shè)備和自動(dòng)生產(chǎn)線的控制系統(tǒng)必須具有極高的可靠性和靈敏性。可編程序控制器正是順應(yīng)這一要求出現(xiàn)的,它是已微處理器為基礎(chǔ)的通用控制裝置。工廠自動(dòng)化及傳送系統(tǒng)也深受其影響,使得現(xiàn)代工廠自動(dòng)化程度和信息集成程度的要求也越來越高。為了適應(yīng)現(xiàn)代自動(dòng)化傳送的要求,PLC控制逐漸取代繼電接觸器控制成為傳送控制的主要環(huán)節(jié),使控制系統(tǒng)更加安全、迅速、可靠。PLC的推廣應(yīng)用在我國得到迅猛的發(fā)展,它已經(jīng)廣泛應(yīng)用在各種機(jī)械設(shè)備和生產(chǎn)過程的電氣控制裝置中。了解PLC
3、的工作原理,具備設(shè)計(jì),調(diào)試和維護(hù)PLC控制系統(tǒng)的能力,已成為現(xiàn)代工業(yè)對(duì)電氣技術(shù)人員和工科學(xué)生的基本要求。關(guān)鍵詞:PLC傳送系統(tǒng)繼電器控制-28-AbstractSincetheninetiesthetwentiethcentury,thecontinuousdevelopmentofthecomputerledtorevolutionarychangesinallfields.Withthemicroprocessor,computertechnologyandtherapiddevelopmentofdigitalcommunicationt
