Monitoring system and method for acquiring coal mine underground dust concentration based on images

Abstract

The invention relates to a monitoring system and method for acquiring coal mine underground dust concentration based on images, and belongs to the technical field of coal mines. The monitoring system comprises a walking track, a detection unit and a control unit, wherein the detection unit and the control unit move along the walking track; a camera, an illuminometer, a hygrometer, a light source set, a data processing unit and a control unit are arranged on the walking track; the data processing unit is connected with the control unit, and the control unit is connected with the camera, the illuminometer, the hygrometer and the light source set; the walking track is composed of two parallel tracks which are arranged along the two sides of the side wall of the roadway respectively; and the camera is installed at the height of a breathing zone of an operator so as to obtain the dust concentration near the breathing zone of the operator. Compared with traditional coal mine underground dust concentration fixed-point monitoring, the monitoring system and the method can obtain coal mine underground particulate matter concentration space distribution, and a foundation is laid for coal mine underground dust concentration global monitoring.

Description

technical field [0001] The invention belongs to the technical field of coal mines, and relates to a monitoring system and method for acquiring underground dust concentration in coal mines based on images. Background technique [0002] At this stage, the main way to obtain the underground dust concentration is on-site sampling and weighing, or to measure the dust concentration through a dust concentration detector and a dust concentration sensor. These methods all use fixed-point measurement methods, and the detection process is cumbersome or the monitoring results are not very informative. However, it can only obtain the dust concentration at a certain point of the downhole operation site, but cannot obtain the spatial distribution and diffusion and migration trend of the downhole dust. It is difficult to provide more accurate dust suppression and dust prevention suggestions and measures for downhole operations. Obtaining coal mine underground dust concentration with the ima...
