dcs控制系統是一種常用的操作系統，現在很多的操作員都可以熟練的使用這種操作系統。大家在使用的時候對于他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控制系統的定義和特點吧。

虛擬dcs(virtual dcs)是相對于在過，程工業(yè)系統中運行的真實dcs(real dcs)而言的，"虛擬dcs"就是將真實dcs在非dcs的計算機系統中以某種形式再現。"虛擬"是現今廣泛使用的一種高新技術概念，比如有實現視景模擬的"虛擬現實"、采用crt交互的"虛擬儀表"、構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、軟件和網絡系統之上的。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，而不是一般的物理系統。虛擬dcs就是要在計算機系統上再現計算機系統，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中，盡可能真實地再現集散控制計算機系統。虛擬dcs正是過程工業(yè)數字化的基礎之一。

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

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

dcs控制系統的定義和特點已經介紹完了，現在大家對于用戶來說了解了dcs控制系統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
