详细说明
    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。
