DCS多层分级控制系统

DCS的基本设计思想是采用控制分散、操作和管理集中的思路，实现多层分级控制和合作的结构。目前，主要应用在冶金、电力和石化等领域。

DCS 是实现多层分级控制的系统，在使用的过程中具有两个基本的分级环节：现场控制单元和操作站。

DCS基本分级环节

● 现场控制单元：

指远离控制中心而在现场附近使用的控制系统，可根据DCS本身机构实现对现场的监控和控制。现场控制单元的使用需要准备不同的设备，如配置插件，即根据系统的要求配置相应的中央处理器插件、电源插件和通信插件等，为后期的分级控制奠定基础；

冗余配置是分级控制系统中重要的环节之一，在配置的过程中要对主机插件、电源插件和通信插件等实现冗余配置；实现随现场的分级控制和监测需要对不同的硬件添加DCS，确保分级控制的可靠性。

● 操作站：

操作站中记录并显示控制系统中的不同数据，是展示人机交互的场所，常用的操作站中包括系主机控制、显示设备和键盘输入设备等，是主要使用人工操作记录和反馈的场所，主要实现显示不同数据、报警和操作等多种重要功能。
