dcs控制系統(tǒng)是一種常用的操作系統(tǒng)，現(xiàn)在很多的操作員都可以熟練的使用這種操作系統(tǒng)。大家在使用的時候?qū)τ谒�的定義和特點都有了解嗎，這對于用戶的使用是很重要的，今天小編就來為大家具體介紹一下dcs控制系統(tǒng)的定義和特點吧。

虛擬dcs(virtual dcs)是相對于在過，程工業(yè)系統(tǒng)中運行的真實dcs(real dcs)而言的，"虛擬dcs"就是將真實dcs在非dcs的計算機系統(tǒng)中以某種形式再現(xiàn)。"虛擬"是現(xiàn)今廣泛使用的一種高新技術概念，比如有實現(xiàn)視景模擬的"虛擬現(xiàn)實"、采用crt交互的"虛擬儀表"、構(gòu)建遠程多媒體雙向通信的"虛擬會議"等等。當然，虛擬技術是完全建立在當今高性能的計算機硬件、軟件和網(wǎng)絡系統(tǒng)之上的。虛擬dcs不同于其它虛擬技術的是，其被虛擬對象也是計算機系統(tǒng)，而不是一般的物理系統(tǒng)。虛擬dcs就是要在計算機系統(tǒng)上再現(xiàn)計算機系統(tǒng)，具體地說，就是要在一種通常為開放平臺計算機信息管理系統(tǒng)中，盡可能真實地再現(xiàn)集散控制計算機系統(tǒng)。虛擬dcs正是過程工業(yè)數(shù)字化的基礎之一。

在實際應用中，為了達到設計調(diào)試、人員培訓、檢測診斷等系統(tǒng)應用目標，需要將真實dcs在非dcs的計算機系統(tǒng)中再現(xiàn)。目前共有三種形式，是分別根據(jù)dcs的控制設計、離線組態(tài)和構(gòu)成運行系統(tǒng)等生命周期的不同階段獲取系統(tǒng)資源而實現(xiàn)的，

dcs是計算機技術、控制技術和網(wǎng)絡技術高度結(jié)合的產(chǎn)物。dcs通常采用若干個控制器(過程站)對一個生產(chǎn)過程中的眾多控制點進行控制，各控制器間通過網(wǎng)絡連接并可進行數(shù)據(jù)交換。操作采用計算機操作站，通過網(wǎng)絡與控制器連接，收集生產(chǎn)數(shù)據(jù)，傳達操作指令。因此，dcs的主要特點歸結(jié)為一句話就是：分散控制集中管理。

dcs控制系統(tǒng)的定義和特點已經(jīng)介紹完了，現(xiàn)在大家對于用戶來說了解了dcs控制系統(tǒng)的特點和定義在以后的使用中會更加的便利，在操作中也會更加的靈活
