DCS通常采用若干個(gè)控制器(過程站)對(duì)一個(gè)生產(chǎn)過程中的眾多控制點(diǎn)進(jìn)行控制,各控制器間通過網(wǎng)絡(luò)連接并可進(jìn)行數(shù)據(jù)交換。生產(chǎn)控制操作采用計(jì)算機(jī)操作站,通過網(wǎng)絡(luò)與控制器連接,收集生產(chǎn)數(shù)據(jù),傳達(dá)操作指令。
從結(jié)構(gòu)上劃分,DCS包括過程級(jí)、操作級(jí)和管理級(jí)。過程級(jí)主要由過程控制站、I/O單元和現(xiàn)場(chǎng)儀表組成,是系統(tǒng)控制功能的主要實(shí)施部分。
操作級(jí)包括:操作員站和工程師站,完成系統(tǒng)的操作和組態(tài)。管理級(jí)主要是指工廠管理信息系統(tǒng)(MIS系統(tǒng)),作為DCS更高層次的應(yīng)用,目前國(guó)內(nèi)紙行業(yè)應(yīng)用到這一層的系統(tǒng)較少。
