dcs控制系统是一种常用的操作系统，现在很多的操作员都可以熟练的使用这种操作系统。大家在使用的时候对于他的定义和特点都有了解吗，这对于用户的使用是很重要的，今天小编就来为大家具体介绍一下dcs控制系统的定义和特点吧。

虚拟dcs(virtual dcs)是相对于在过，程工业系统中运行的真实dcs(real dcs)而言的，"虚拟dcs"就是将真实dcs在非dcs的计算机系统中以某种形式再现。"虚拟"是现今广泛使用的一种高新技术概念，比如有实现视景模拟的"虚拟现实"、采用crt交互的"虚拟仪表"、构建远程多媒体双向通信的"虚拟会议"等等。当然，虚拟技术是完全建立在当今高性能的计算机硬件、软件和网络系统之上的。虚拟dcs不同于其它虚拟技术的是，其被虚拟对象也是计算机系统，而不是一般的物理系统。虚拟dcs就是要在计算机系统上再现计算机系统，具体地说，就是要在一种通常为开放平台计算机信息管理系统中，尽可能真实地再现集散控制计算机系统。虚拟dcs正是过程工业数字化的基础之一。

在实际应用中，为了达到设计调试、人员培训、检测诊断等系统应用目标，需要将真实dcs在非dcs的计算机系统中再现。目前共有三种形式，是分别根据dcs的控制设计、离线组态和构成运行系统等生命周期的不同阶段获取系统资源而实现的，

dcs是计算机技术、控制技术和网络技术高度结合的产物。dcs通常采用若干个控制器(过程站)对一个生产过程中的众多控制点进行控制，各控制器间通过网络连接并可进行数据交换。操作采用计算机操作站，通过网络与控制器连接，收集生产数据，传达操作指令。因此，dcs的主要特点归结为一句话就是：分散控制集中管理。

dcs控制系统的定义和特点已经介绍完了，现在大家对于用户来说了解了dcs控制系统的特点和定义在以后的使用中会更加的便利，在操作中也会更加的灵活
