Abstract

The invention provides a mine dust measuring system based on images. The system mainly comprises a light source, an image acquisition device and a control device; an open air chamber is adopted; no air pump or dust processing equipment is needed; the image acquisition device is used for acquiring light source images; dust detection is completed directly through image processing,. The system is simple in structure and convenient to install and maintain; the invention further provides a method for automatically cleaning a lens cover and a light source cover, a method for removing dust between the image acquisition device and the light source, a system zero setting method, a system sensitivity calibration method and the like; the accuracy of system monitoring data is further guaranteed; and the system is particularly suitable for an underground dusty environment and is wide in application range.

Description

technical field [0001] The invention relates to an image-based mine dust measurement system, which relates to the fields of digital image processing technology, automatic control technology, data processing technology and the like. Background technique [0002] Coal is the main energy in my country, accounting for about 70% of the primary energy. The coal industry is a high-risk industry. Accidents such as gas, floods, fires, roofs, and coal dust have plagued coal mine safety production. Among them, coal dust explosions have caused great damage and high death rates. Therefore, mine dust monitoring is an important guarantee for coal mine safety. important measures for disease prevention and control. At present, mine dust monitoring technologies mainly include: tribostatic method, light scattering method, light absorption method, capacitance method, β-ray method, ultrasonic method, microwave method. The measurement principle of the capacitance method is simple, but there is ...
