PLC是現(xiàn)代工業(yè)的三大支柱之一,是可靠性高、應(yīng)用非常廣泛的工業(yè)控制產(chǎn)品。在中大型模塊化的PLC產(chǎn)品中,CPU模塊(中央處理器)是PLC的中心。一些重大的工業(yè)生產(chǎn)線往往要求連續(xù)運(yùn)行不能停頓,而可靠性再高的PLC也不能保證故障為零,因此,雙CPU的冗余控制是一種滿足連續(xù)生產(chǎn)要求、提高系統(tǒng)可用性的有效手段。下面以熔鹽爐自控系統(tǒng)為實(shí)例詳述雙CPU冗余控制的實(shí)現(xiàn)方法。
一、熔鹽爐自動(dòng)系統(tǒng)綜述
熔鹽爐自控系統(tǒng)是一水硬鋁管道化溶出生產(chǎn)線上的重要環(huán)節(jié),控制熔鹽的加熱和循環(huán),用熔鹽的熱量去循環(huán)加熱鋁礦石漿。鋁礦石漿的加熱至關(guān)重要,影響最終產(chǎn)品—氧化鋁的質(zhì)量和產(chǎn)量,因此,熔鹽的溫度控制和循環(huán)控制非常重要。
由于熔鹽爐系統(tǒng)在管道化工程中的重要性,同時(shí)考慮到熔鹽是一種活躍的化學(xué)品,在不同的溫度下有不同的形態(tài),低溫下凝固,高溫下不穩(wěn)定會(huì)發(fā)生化學(xué)反應(yīng),從而腐蝕管壁甚至于爆炸,所以安全、可靠、操作簡(jiǎn)便和自動(dòng)化管理是系統(tǒng)設(shè)計(jì)的關(guān)鍵,因此考慮用一套雙CPU冗余的PLC、兩套工控機(jī)、高質(zhì)量的傳感器、變送器和執(zhí)行機(jī)構(gòu)來控制兩臺(tái)1200萬大卡的熔鹽爐、一臺(tái)鹽泵、一組鹽閥、一個(gè)熔鹽槽和其他相關(guān)設(shè)備,實(shí)現(xiàn)熔鹽的加熱和循環(huán)過程自動(dòng)化、計(jì)算機(jī)操作、監(jiān)控和管理的自動(dòng)化控制。
