Detailed research the main body of a book has been carried out on the PLC navar enchasing owing to production line automation mainly. Be system39。s turn to have two conveyer belts , be package box conveyer belt and product conveyer belt. The package box conveyer belt is used to deliver the product package box , whose function is that the package box luck already filling to full is leaked , is uses one to replace to e empty space box and. End being to make the empty space box aim at the product conveyer belt fitly, just the dropin package box is hit by the messenger product, before package box conveyer belt centre install one photoelectricity sensor, in order to check if package box arrive at a place. And the product conveyer belt transmits a product from producing a workshop to package box , pawn some one products deliver to the conveyer belt end , the meeting automation dropin package box inner, change from another sensor being counting pulse. Navar has accuracy height , the low , antiinterference ability of cost is strong , the malfunction leads a characteristic low , operation upkeep waits for simplely, have fine application value. Key words : programming controller Automation encasement navar The conveyer belt is controlled 第 4 頁 共 30 頁 4 目錄 摘要 ................................................................................................................................ 2 Abstract .......................................................................................................................... 3 目錄 ................................................................................................................................ 4 第一章 緒論 .................................................................................................................. 5 課題背景 .......................................................................................................... 5 生產(chǎn)線自動(dòng)化的發(fā)展概況 .............................................................................. 5 國(guó)內(nèi)生產(chǎn)線自動(dòng)化發(fā)展概況 ................................................................ 5 系統(tǒng)、基于 PC 的控制系統(tǒng)等。 .................................................................................. 5 國(guó)外生產(chǎn)線自動(dòng)化發(fā)展概況 ................................................................ 6 本文主要研究?jī)?nèi)容 .......................................................................................... 7 設(shè)計(jì)任務(wù)書 ............................................................................................. 7 主要解決的問題 .................................................................................... 8 第 2 章 控制系統(tǒng)的設(shè)計(jì) .............................................................................................. 9 采用傳統(tǒng)繼電 ———— 接觸器電氣控制系統(tǒng) ..................................... 9 采用 PLC 可編程序控制器控制系統(tǒng) .................................................. 9 方案比較與選擇 .................................................................................. 10 PLC 的硬件結(jié)構(gòu)及工作原理 ........................................................................ 10 PLC 控制系統(tǒng)組成 .............................................................................. 11 PLC 的工作過程 .................................................................................. 11 控制系統(tǒng)構(gòu)成圖和工作流程 ........................................................................ 12 控制系統(tǒng)構(gòu)成圖 .................................................................................. 12 控制系統(tǒng)工作流程 ...
