Embodiment Construction

[0035] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0036] figure 1 It is a flow chart of a method for controlling the output of the damper opening adjustment interval of the dust removal equipment according to the embodiment of the present invention, including the following steps:

[0037] Step S1: read the external enable signal, and map the enable signal into the internal enable bit;

[0038] Step S2: Judging the state of the output value adjustment control function, if the function is not activated, then end the regulation, if the function is activated, then proceed to step S3;

[0039] Step S3: read the external setting parameters, the external setting parameters include state value V, target interval [I...

Abstract

The invention relates to a dedusting equipment air door opening degree adjusting interval control output method and a control system. A required opening degree numerical value adjusting interval is maintained according to an opening degree state of an air door of dedusting equipment. Through a numerical value adjustment control module, a set value required by the opening degree of the air door ofthe dedusting equipment increases or decreases a numerical value needing to be adjusted in set time according to a set adjustment quantity in a numerical value adjustment interval so that the openingdegree of the air door of the dedusting equipment is effectively controlled. Problems that common manual control is complex and equipment overshoot is easily caused in an air door opening degree interval control adjustment output process of existing dedusting equipment are solved, coordination control of an interval control adjustment output numerical value is achieved, and an overshoot situationof a control target is avoided.

Description

technical field [0001] The invention relates to the technical field of industrial process control, in particular to a control output method and a control system for adjusting the opening degree of a damper of dust removal equipment. Background technique [0002] The purpose of industrial process control is mainly to maintain the controlled variable equal to the set value. However, when considering the actual factors such as product output, quality and energy consumption, the system output is no longer strictly set value tracking, only the controlled variable It can be controlled within a certain range. The adoption of interval control can make the control process have a greater degree of freedom in suppressing disturbances, and at the same time, it can also reduce the frequency of control action. In short, interval control means that when the output value violates the target interval, the control action corrects the output value and returns to the interval, and when the out...
