用螺旋式上升轮来描述近半个世纪以来工业过程检测及控制仪表的演变进展历程或许是恰如其份的。从五十年代习用的基地式仪表进展到七、八十年代的屏装仪表,从就地的分散检测、控制变成为主控室内仪表屏前集中监测、控制。这种演变进展对工业生产带来的好处是不言而喻的。七十年代中期问世的DCS不但摒弃了庞大的仪表屏,其信息高度集中并能予以综合应用的潜力,可对生产管理 Using spiraling ascending wheels to describe the evolution of industrial process instrumentation and control instrumentation over the last half-century may be appropriate. From the fifties used base instrument progress to the seven, eighty time the screen instrument, from the scattered test, the control becomes the main control indoor instrument screen centralized monitoring and control. The benefits of this evolution to industrial production are self-evident. The advent of DCS in the mid-1970s not only abandoned the huge dashboard screen, its information is highly concentrated and can be integrated application of the potential of production management
