DCS多層分級控制系統

DCS的基本設計思想是采用控制分散、操作和管理集中的思路，實現多層分級控制和合作的結構。目前，主要應用在冶金、電力和石化等領域。

DCS 是實現多層分級控制的系統，在使用的過程中具有兩個基本的分級環節：現場控制單元和操作站。

DCS基本分級環節

● 現場控制單元：

指遠離控制中心而在現場附近使用的控制系統，可根據DCS本身機構實現對現場的監控和控制。現場控制單元的使用需要準備不同的設備，如配置插件，即根據系統的要求配置相應的中央處理器插件、電源插件和通信插件等，為后期的分級控制奠定基礎；

冗余配置是分級控制系統中重要的環節之一，在配置的過程中要對主機插件、電源插件和通信插件等實現冗余配置；實現隨現場的分級控制和監測需要對不同的硬件添加DCS，確保分級控制的可靠性。

● 操作站：

操作站中記錄并顯示控制系統中的不同數據，是展示人機交互的場所，常用的操作站中包括系主機控制、顯示設備和鍵盤輸入設備等，是主要使用人工操作記錄和反饋的場所，主要實現顯示不同數據、報警和操作等多種重要功能。
