DCS又称为集散控制系统,是用于生产过程的集中控制或是分类并行控制的一种复杂的工业系统,它属于一种综合型设备控制装置。下面浙大中控DCS卡件厂家就来对DCS系统的工作流程进行分析。
DCS, also known as distributed control system, is a complex industrial system used for centralized control or classified parallel control of production process. It belongs to a comprehensive equipment control device. Next, Zhejiang University central control DCS card manufacturer will analyze the workflow of DCS system.
DCS的产生是随着现代大规模工业生产自动化的不断改进,导致生产过程中对系统的要求渐渐复杂,这时便需要一种能够进行并行集中控制的工业系统来总揽大局,于是DCS便产生了,它能够将通信网络与自动控制系统相结合,对工业生产有着高水平的效率提升。经典的DCS系统一般由三部分组成:集中管理系统、分散控制装置和通信网络连接模块。
With the continuous improvement of modern large-scale industrial production automation, the requirements for the system in the production process are becoming more and more complex. At this time, an industrial system that can carry out parallel centralized control is needed to take charge of the overall situation, so DCS came into being. It can combine the communication network with the automatic control system and improve the efficiency of industrial production at a high level. The classic DCS system is generally composed of three parts: centralized management system, distributed control device and communication network connection module.

DCS可以根据实际过程控制要求使用配置软件来设置和操控硬件和程序模块,例如选择控制电路,控制方案并在配置后生成趋势屏幕。DC会在启动前生成一系列配置文件,这些文件可以在系统运行之前根据各种文件属性加载到过程控制单元和操作员站中。随后过程控制单元从固化在EPROM中的功能模块库中找到相应的控制算法,并根据配置信息文件的内容进行启动流程。
DCs can use configuration software to set and control hardware and program modules according to the actual process control requirements, such as selecting control circuit, control scheme and generating trend screen after configuration. The DC will generate a series of configuration files before startup, which can be loaded into the process control unit and operator station according to various file properties before the system runs. Subsequently, the process control unit finds the corresponding control algorithm from the function module library solidified in EPROM, and starts the process according to the content of the configuration information file.
DCS控制系统能够使用冗余的控制单元来保证整体系统的稳定性,这样可在系统发生重大故障无法继续进行的情况下提供无干扰的切换至备用模组的功能,并确保系统运行状态不丢失。
The DCS control system can use redundant control units to ensure the stability of the overall system, which can provide the function of switching to the standby module without interference in the event of a major failure of the system, and ensure that the system operation state is not lost.
DCS控制系统通常具有完整的系统数据库,数据库系统中的每个链接都提供对相关数据的实时引用,并灵活方便地支持其他链接。同时,DCS的PLC组态设备中,每个链接均具备对应的数据链接,能够在动态调取时进行实时应用,确保系统正常运行。
DCS control system usually has a complete system database. Each link in the database system provides real-time reference to relevant data, and flexibly and conveniently supports other links. At the same time, in the PLC configuration equipment of DCS, each link has a corresponding data link, which can be applied in real time during dynamic retrieval to ensure the normal operation of the system.
