基于plc的自動(dòng)控制分揀系統(tǒng)的設(shè)計(jì)說明

1、 I / 30摘 要PLC控制是目前工業(yè)上最常用的自動(dòng)化控制方法，由于其控制方便，能夠承受惡劣的環(huán)境，因此，在工業(yè)上優(yōu)于單片機(jī)的控制。PLC將傳統(tǒng)的繼電器控制技術(shù)、計(jì)算機(jī)技術(shù)和通信技術(shù)融為一體,專門為工業(yè)控制而設(shè)計(jì),具有功能強(qiáng)、通用靈活、可靠性高、環(huán)境適應(yīng)性強(qiáng)、編程簡(jiǎn)單、使用方便以與體積小、重量輕、功耗低等一系列優(yōu)點(diǎn),因此在工業(yè)上的應(yīng)用越來越廣泛。本文主要講述PLC在

2、材料分揀系統(tǒng)中的應(yīng)用，利用可編程控制器( PLC) ,設(shè)計(jì)成本低、效率高的材料自動(dòng)分揀裝置。以PLC 為主控制器,結(jié)合氣動(dòng)裝置、傳感技術(shù)、位置控制等技術(shù),現(xiàn)場(chǎng)控制產(chǎn)品的自動(dòng)分揀。 系統(tǒng)具有自動(dòng)化程度高、運(yùn)行穩(wěn)定、精度高、易控制的特點(diǎn),可根據(jù)不同對(duì)象,稍加修改本系統(tǒng)即可實(shí)現(xiàn)要求。關(guān)鍵詞:可編程控制器，分揀裝置，控制系統(tǒng)，傳感器ABSTRACTPLC control is the most commonly used industrial
