浙大中控DCS卡件到底是什么?

 说到控制系统很多人貌似说得头头是道,继续深究下去,什么是控制器,什么是PLC,什么是DCS,什么是FCS?三两句话介绍完基本概念后,顿时语塞,怎么聊都感觉枯燥生硬。今天浙大中控DCS卡件的小编来挑战一下这个枯燥的话题,什么是DCS?
  When it comes to the control system, many people seem to have a clear idea. They continue to study it deeply. What is controller, what is PLC, what is DCS and what is FCS? After introducing the basic concepts in three or two sentences, I suddenly stop talking and feel dull and stiff. Today, Zhejiang University central control DCS card editor to challenge this boring topic, what is DCS?
  我们首先可以明确的是:DCS是历史悠久的典型控制系统形态。控制系统分上下位机,上位机组态偏重GUI(图形用户界面),下位机组态偏重算法。
  We can make it clear that DCs is a typical control system with a long history. The control system is divided into upper and lower computers, the upper computer configuration focuses on GUI (graphical user interface), and the lower computer configuration focuses on algorithm.
  有朋友可能会问什么是组态?
  A friend may ask what is configuration?
  其实组态就是搭建系统软件和硬件环境,再简单地说,组态就是用已有的简单功能组合出更复杂的功能。
  In fact, configuration is to build the software and hardware environment of the system. To put it simply, configuration is to combine more complex functions with existing simple functions.

  那上下位机又是什么呢?
  What are the upper and lower computers?
  举个例子:设想自己开发一个控制系统。首先要做的是告诉计算机自己想干什么,然后由计算机通知控制器,然后控制器再告诉执行器具体该怎么做。这里面我其实只跟计算机发生对话,这里的计算机就是上位机,接受计算机指令的控制器就是下位机。
  For example: imagine developing a control system yourself. The first thing to do is to tell the computer what it wants to do, and then the computer tells the controller, and then the controller tells the actuator how to do it. In fact, I only have a dialogue with the computer. The computer here is the upper computer, and the controller receiving the computer's instructions is the lower computer.
  其实计算机和控制器本质上说都是计算机,只是外在表现形式,应用环境和编程方式的差异,导致我们要采取一些便于理解的命名方式。上位机要跟人互动,所以偏重GUI,有显示器或触摸屏、鼠标和键盘灯外设等人机交互设备。下位机要跟执行机构互动,所以偏重算法,人们要把需求编写成可执行的程序下载到下位机,上位机给出的指令触发下位机程序执行,下位机更像是一个黑盒子,执行过程中人们无法直观的看到每一个过程和步骤,只能对结果进行分析,对不对,准不准,好不好。
  In fact, computers and controllers are computers in essence, but the differences in external forms of expression, application environment and programming methods lead us to adopt some easy to understand naming methods. The upper computer needs to interact with people, so it pays more attention to GUI, and has human-computer interaction devices such as display or touch screen, mouse and keyboard lamp peripherals. The lower computer needs to interact with the executive mechanism, so it focuses on algorithms. People need to write executable programs and download them to the lower computer. The instructions given by the upper computer trigger the execution of the lower computer program. The lower computer is more like a black box. People can't directly see each process and step in the execution process, but can only analyze the results, right, accurate, good or bad.
