Problems solved by technology

[0003] During the sintering process, the grate bars are easily deformed or even fall off under the action of high temperature. If a large number of grate bars are deformed or fall off, the air intake of the sintering machine trolley will be too large, which will affect the output and quality of sinter
[0004] At present, the operator usually infers the condition of the grate bar by observing the sintered ore sintered by the sintering machine trolley. However, only when the grate bar has been seriously damaged can the operator infer the damage of the grate bar from the sintered ore, so that the grate bar cannot be found in time. Bar damaged

Abstract

The invention discloses a method and device for determining the damage degree of a grate of a sintering machine trolley. The method comprises the steps that an initial image with the grate of sintering machine trolley is acquired; a first target image of a region in which the grate is located is extracted from the initial image; a second target image including a target pixel point characterizing the edge of the grate is acquired from the target image; and the cumulative length of all straight line segments formed by target pixel points characterizing the edge of the grate in the second targetimage is calculated; and based on the cumulative length, the damage degree of the grate is determined. According to the embodiment of the invention, the current damage degree of the sintering machinetrolley can be directly determined through the cumulative length; the time for the grate to reach arbitrary damage degree can be determined; and the problem that grate damage cannot be found in time in the prior art is solved.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a method and device for determining the damage degree of a grate bar of a sintering machine trolley. Background technique [0002] The sintering machine trolley is the key equipment for the sintering process of smelting ore. The important part of the sintering machine trolley is the grate. There are two grate bars, and there is a certain distance between two adjacent grate bars, which are used for drafting and combustion-supporting during the sintering process. [0003] During the sintering process, the grate bars are easily deformed or even fall off under high temperature. If a large number of grate bars are deformed or fall off, the air intake of the sintering machine trolley will be too large, which will affect the output and quality of sinter. [0004] At present, the operator usually infers the condition of the grate bar by observing the sintered ore sintered b...
