隨著工業(yè)企業(yè)自動(dòng)化技術(shù)的發(fā)展,PLC (Programmable Logic Controller,又稱可編程控器),以其可靠性、靈活性、優(yōu)良的性能價(jià)格比、使用方便等特點(diǎn)在工業(yè)控制領(lǐng)域迅猛發(fā),得到了越來越廣泛的應(yīng)用。
石油焦是鋁電解用碳素陽(yáng)極生產(chǎn)的主要原料。石油焦轉(zhuǎn)運(yùn)系統(tǒng),是把貯存在倉(cāng)庫(kù)中的石油焦,經(jīng)過破碎篩分處理成滿足煅燒需要的原料,輸送到煅前料倉(cāng)。由于該系統(tǒng)邏輯控制點(diǎn)多、自動(dòng)化程度高、上下游設(shè)備間關(guān)聯(lián)度大,所以選用PLC進(jìn)行自動(dòng)控制,并設(shè)立上位機(jī)進(jìn)行全系統(tǒng)監(jiān)控。本文著重討論PLC在系統(tǒng)中控制功能的實(shí)現(xiàn)和上位機(jī)監(jiān)控界面的開發(fā)。
