Problems solved by technology

[0006] The present invention aims to solve the problem that the DCS control system in the above-mentioned prior art cannot comprehensively control the production of short fiber stock solution viscose as a whole, and the control operation is cumbersome, overcomes its defects, and provides a short fiber stock solution viscose production system. The automatic control system automatically controls all aspects of production to ensure the long-term continuous operation of the entire production process. The failure of the automatic control system will not affect the progress of the process. The design of the control system is reasonable, the control steps are simple, and the manual labor is greatly reduced. labor

Abstract

The invention provides an automatic control system in production of short fiber stock solution viscose, belongs to the field of artificial fibers, and aims to solve the problems that a distributed control system (DCS) cannot comprehensively control the production of the short fiber stock solution viscose as a whole and control operation is complicated in the prior art. A redundant process control system is constructed by redundant process control software, so that an impregnation alkali blending automatic control system, a pulp impregnation automatic control system, an alkaline fiber pressing automatic control system, an alkaline fiber automatic ageing control system, an alkaline fiber yellowing automatic control system and a viscose ripening automatic control system are established to automatically control each link in the production, the long-period continuous operation of the whole production process is ensured, and the process cannot be influenced due to the failure of the automatic control system; and the control system is reasonable in design and simple in control steps, and manual labor is greatly reduced.

Description

technical field [0001] The present invention relates to a kind of DCS automatic control system, more specifically, the present invention relates to a kind of automatic control system of viscose glue production of stock solution of short fiber. It belongs to the field of man-made fibers. Background technique [0002] Automatic control refers to the use of external equipment or devices to make a certain working state or parameter of a machine, equipment or production process automatically operate according to a predetermined law without direct participation of humans. Automatic control is relative to the concept of manual control, which refers to the use of control devices to make the controlled object or process automatically run according to the predetermined law without the participation of anyone. [0003] The research of automatic control technology is beneficial to liberate human beings from complicated, dangerous and cumbersome working environment and greatly improve t...
