畢業(yè)設(shè)計(jì)說明書(論文)設(shè)計(jì)題目:1200自動混合液體機(jī)控制系統(tǒng)設(shè)計(jì)專業(yè):班級:學(xué)號:姓名:指導(dǎo)教師:2021年7月10日摘要隨著科技的發(fā)展，PLC的開發(fā)與應(yīng)用把各國的工業(yè)推向自動化、智能化。強(qiáng)大的抗干擾能力使它在工業(yè)方面取代了微型計(jì)算機(jī)，方便的軟件編程使他代替了繼電器的繁雜連線，靈活、方便，效率高。本次設(shè)計(jì)主要是對兩種液體混合攪拌機(jī)PLC控制系統(tǒng)的設(shè)計(jì)，將兩種液體按一定比例混合，經(jīng)過電動機(jī)攪拌均勻以后才能將混合后的液體輸出容器。形成循環(huán)狀態(tài)。液體混合系統(tǒng)的控制設(shè)計(jì)考慮其動作的連續(xù)性以及被控設(shè)備動作的之間的相互關(guān)聯(lián)性、針對不同的工作狀態(tài)，進(jìn)行相應(yīng)的動作控制輸出，從而實(shí)現(xiàn)液體混合系統(tǒng)從一種液體加入到完成輸出的這樣一個周期控制工作的程序?qū)崿F(xiàn)。設(shè)計(jì)以液體混合控制系統(tǒng)為中心，從控制系統(tǒng)的硬件系統(tǒng)組成、軟件選用到系統(tǒng)的設(shè)計(jì)過程(包括設(shè)計(jì)方案、設(shè)計(jì)流程、設(shè)計(jì)要求、梯形圖設(shè)計(jì)、外部連線通信等)，旨在對其中的設(shè)計(jì)及制作過程做簡單的介紹和說明。設(shè)計(jì)采用PLC去實(shí)現(xiàn)設(shè)計(jì)要求。本次設(shè)計(jì)的主要研究范圍及要求達(dá)到的技術(shù)參數(shù)有:(1)使液體混合能實(shí)現(xiàn)安全、高效:(2)滿足液體混合的各項(xiàng)技術(shù)要求:(3)具體內(nèi)容包括多種液體混合控制方案的設(shè)計(jì)等。本課題應(yīng)解決的主要問題是如何使PLC實(shí)現(xiàn)多種液體的混合控制功能，在相關(guān)的文獻(xiàn)當(dāng)中用PLC對其濕合液體控制的研究尚不多見，以致人們難以租據(jù)他的其體情況正確選用參數(shù)進(jìn)行系統(tǒng)控制，也就難以滿足提高質(zhì)量和效率，降低成本的要求。本次設(shè)計(jì)就是基于以上問題進(jìn)行的一-些探索。關(guān)鍵詞:多種液體、混合控制、觸摸屏、自動控制、PLC。Abstractthedevelopmentofscienceandtechnology,thedevelopmentofPLC
