描述
SCADA/DCS和PLC的概述SCADA系統(tǒng)是高分布式系統(tǒng),經(jīng)常用于控制地理上分散的資產(chǎn),分散在數(shù)千平方公里,其中集中的數(shù)據(jù)采集和控制至關(guān)重要到系統(tǒng)操作。它們用于配水系統(tǒng),如配水和廢水收集系統(tǒng),油氣管道,電網(wǎng)和鐵路運輸系統(tǒng)。一個SCADA控制中心長期對現(xiàn)場進(jìn)行集中監(jiān)控通信網(wǎng)絡(luò),包括監(jiān)控報警和處理狀態(tài)數(shù)據(jù)?;谛畔倪h(yuǎn)程站接收到的,可以將自動化或操作者驅(qū)動的監(jiān)控命令推送到遠(yuǎn)程站控制設(shè)備,通常被稱為現(xiàn)場設(shè)備?,F(xiàn)場設(shè)備控制本地諸如打開和關(guān)閉閥門和斷路器的操作,從傳感器系統(tǒng)收集數(shù)據(jù),以及監(jiān)控當(dāng)?shù)丨h(huán)境的報警條件。
DCS用于控制工業(yè)過程,如發(fā)電,油氣煉油,水和廢水處理,以及化學(xué),食品和汽車生產(chǎn)。DCS集成為一個控制架構(gòu),包含監(jiān)督多個集成子系統(tǒng)的監(jiān)督級別的控制它們負(fù)責(zé)控制本地化流程的細(xì)節(jié)。產(chǎn)品和過程控制通常通過部署反饋或前饋控制環(huán)來實現(xiàn),其中關(guān)鍵產(chǎn)品和/或工藝條件自動保持在所需的設(shè)定點附近。完成所需產(chǎn)品和/或工藝公差在指定的設(shè)定點附近,具體的可編程控制器(PLC)被用于現(xiàn)場,PLC上的比例,積分和/或差分設(shè)置被調(diào)整到提供期望的公差以及過程紊亂期間的自校正速率。使用DCS廣泛地在基于過程的行業(yè)。
