所谓的DCS即分布式控制系统在国内又称之为集散控制系统，具体不再多说，下面讲一下新手如何学习dcs系统，这是所有接触dcs行业新手共同面临的问题，下面我就对DCS谈谈自己的一些看法：
对于DCS，主要关心以下几个问题： 各部分网络的通信协议；冗余（服务器，电源，主控
制器，重要I/O模块）；如何配置，I/O的输入输出特性。I/O常用的有模拟量输入AI，模拟量输出AO，开关量输入DI，开关量输出DO。此外还有SOE，PI等。其中AI信号有RTD（热电阻信号），TC（热电偶信号），4-20MA信号（也可以是0-20MA，0-5V）。了解完这些，接下来就是学习组态，多练练修改控制方案，给主控制器下装方案（不影响生产的情况下进行）。
再者就是软硬件结合理解，在实际面对控制现场生产，你很快便会入门。在此以后可以学习DCS系
统与PLC的通信，MIS，SIS。
对理论知识的建议：自动控制原理（不用深究，了解到PID即可，因为就算是很基本的PID，现场也未必能投上自动）；常用编程语言（FBD，LD等），这个在组态的过程中自然就学会了；模拟电路和数字电路初步，这个也不用深入；计算机知识，尤其是网络知识，说到底现在DCS的发展完全是建立在计算机软硬件飞速发展的基础上的。 以上仅是南京睿派仪表对大家的一点简析，希望对你初期学习能够有所帮助。
With the development of automation technology, the original PLC controller can not meet the requirements of some large projects. In this case, DCS control system came into being. DCS control system, also known as distributed system, is a new type of computer control system relative to centralized control system. It is developed and evolved on the basis of centralized control system. In terms of system functions, there is little difference between DCs and centralized control system, but the realization methods of system functions are completely different.The so-called DCS, i.e. distributed control system, is also called distributed control system in China. I won't say more about it. Now let's talk about how novices learn DCS system, which is a common problem faced by all novices in DCS industry. Here are some of my own views on DCS:
For DCS, the following issues are mainly concerned: the communication protocol of each part of the network; Redundancy (server, power supply, master control
Brake, important i/o module); How to configure i/o input / output characteristics. I/o commonly used analog input AI, analog output Ao, switching input Di, switching output do. In addition, SOE, PI, etc. AI signals include RTD (thermal resistance signal), TC (thermocouple signal), 4-20mA signal (also 0-20mA, 0-5V). After understanding these, the next step is to learn the configuration, practice and modify the control scheme more, and install the scheme for the main controller (without affecting the production).
Moreover, the combination of software and hardware is understood. In the actual face of controlling on-site production, you will soon get started. After that, you can learn DCS system
Communication between system and PLC, MIS, SIS.
Suggestions for theoretical knowledge: automatic control principle (it is OK to understand PID without deep study, because even if it is a very basic PID, it may not be able to be put into automatic on site); Common programming languages (FBD, LD, etc.) are learned naturally in the process of configuration; The analog circuit and digital circuit are preliminary, and there is no need to go deep into this; Computer knowledge, especially network knowledge, in the final analysis, the development of DCS is completely based on the rapid development of computer software and hardware. The above is just a brief analysis of Nanjing Ruipai instrument. I hope it can help you in your initial study.
