Detection method and system for working state of mining belt

Abstract

The invention discloses a detection method and system for a working state of a mining belt. The method comprises: two video frames are extracted from a video frame sequence of a mining belt and a gray scale difference value between pixel points of the two video frames at corresponding positions in a preset belt detection area is calculated, so that a corresponding gray scale difference image is obtained; averaging is carried out on gray scale values of all pixel points of the gray scale difference image in a belt detection area to obtain a detection quantity value; the detection quantity value is compared with a preset threshold value to determine a working state of the mining belt. According to the technical scheme, non-contact detection of the mining belt is realized, so that a problem that the working state detection result is affected because the reflective layer on the mining belt is covered by mineral aggregates in the prior art can be solved. Meanwhile, the detection quantity value is obtained by carrying out averaging on gray scale values of all pixel points of the gray scale difference image in a belt detection area, so that the detection result accuracy is guaranteed based on the spatial average operation.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for detecting the working state of a mining belt. Background technique [0002] Today, with the development of my country's economy and the acceleration of industrialization, natural mineral resources such as coal, copper ore and bauxite have shown a tense situation, and the mining industry, as a basic industry of the country, has also attracted more and more attention. [0003] As we all know, the situation in the underground of mining mines is complicated. Once a safety accident occurs, it will not only endanger the personal safety of miners, but also cause production to stagnate. Among them, the mining belt used to transport mineral materials is a crucial equipment in the production of mineral materials, and its working status (including running status and stop status) can be said to be the most concerned issue for managers. The realization of inte...
