Abstract
Collect and distribute navar (DCS) , be to realize the technology guarding administrative controlling to the adjustment , dispersing a controlled member with many microprocessor technology and redundancy technology making use of the modern network technology , modern control technique , artwork display for the basis etc., use the person high reliability and under the control of, administration upper preeminent merit already broad apply to petrochemical industry, metallurgy, electric power and so on industry, be at present be most advanced process control system. Priority has introduced that the DCS redundancy system that hardware , the software structure owing to Rockwell hits the target in paper making industry resolving a scheme
With the standard fliving increasing,papermaking is developing very q uickly .From operating at field to controlling in DCS (Distribute Control System), and from paper quality depending on the work's experience to it controlled by QCS (QualityControl System), from paper aspect depending on the work's eyes to online WIS(WebImage System), these technologies have changed the paper making of mode andprodigiously increased at quality and quantity.On t h is d ecade,th et rendo fd eveloping on paper makingisq uickly.S omepapermillsh aveta kent echnologyin novationo rb uildn ewp aperm achine.Toim proveq ualityand increase quantity and gain the new of profit, these paper machines have adoptedDCS from foreign or homemade.
