Abstract

The invention relates to a mine-use rubber belt longitudinal tearing intelligent infrared detection sensor, and belongs to the technical field of automatic detecting. The mine-use rubber belt longitudinal tearing intelligent infrared detection sensor is characterized by being an intelligent sensor of collecting and extracting position images by means of mine-use rubber belt longitudinal tearing and the dangerous source features thereof and is with a temperature detection function. According to the mine-use rubber belt longitudinal tearing intelligent infrared detection sensor, infrared sensitive devices are used for detecting radiation wavelength changes after metal absorbs infrared rays, the temperature of the position where a rubber belt tears raises, on-line real-time monitoring and early warning to rubber belt longitudinal tearing accidents and the dangerous sources thereof are achieved by means of on-line infrared characteristic imaging for identifying longitudinal tearing occurrences and the positions of the dangerous sources such as metal foreign bodies mixed in coal, and therefore the purposes of early warning and on-line monitoring are well achieved. Especially, the mine-use rubber belt longitudinal tearing intelligent infrared detection sensor can work under a poor working condition under a coal mine, and therefore the reliability, the pertinence and the practicality of detecting are improved.

Description

technical field [0001] The invention relates to an infrared intelligent detection sensor for longitudinal tearing of mining adhesive tape and a use method thereof, belonging to the technical field of automatic detection. Background technique [0002] Belt conveyors are widely used in mines, ports, thermal power generation, metallurgy and other fields that require long-distance real-time transportation. Longitudinal tearing is one of the three catastrophic accidents of mining belt conveyors (longitudinal tearing, transverse fracture, fire) , due to the long working length of the tape, if a longitudinal tear accident occurs, it may cause damage to the entire tape if it cannot be discovered in time, and production cannot be resumed for a long time, resulting in huge economic losses. The main reason for the longitudinal tear of the tape is that the sharp edges and corners of metal foreign objects such as iron brazing, angle steel, channel steel, and screws mixed in the coal are ...
