數(shù)據(jù)采集系統(tǒng)(Data Acquisition System，DAS)是計(jì)算機(jī)應(yīng)用于生產(chǎn)

過(guò)程控制最早、也是最基本的一種類(lèi)型，計(jì)算機(jī)控制系統(tǒng)與所控制的生產(chǎn)過(guò)程密切相關(guān)，根據(jù)生產(chǎn)過(guò)程的復(fù)雜程度和工藝要求的不同，系統(tǒng)設(shè)計(jì)者可采用不同的控制方案?，F(xiàn)從控制目的、系統(tǒng)構(gòu)成的角度介紹幾種不同類(lèi)型的計(jì)算機(jī)控制系統(tǒng)。

數(shù)據(jù)采集系統(tǒng)(DAS)

數(shù)據(jù)采集系統(tǒng)(Data Acquisition System，DAS)是計(jì)算機(jī)應(yīng)用于生產(chǎn)過(guò)程控制最早、也是最基本的一種類(lèi)型，直接數(shù)字控制(Direct Digital Control，DDC)系統(tǒng)是用一臺(tái)計(jì)算機(jī)不僅完成對(duì)多個(gè)被控參數(shù)的數(shù)據(jù)采集，而且能按一定的控制規(guī)律進(jìn)行實(shí)時(shí)決策，并通過(guò)過(guò)程輸出通道發(fā)出控制信號(hào)，現(xiàn)對(duì)生產(chǎn)過(guò)程的閉環(huán)控制，所示。為了操作方便，DDC系統(tǒng)還配置一個(gè)包括給定、顯示、報(bào)警等功能的操作控制臺(tái)。
