Abstract

The invention provides an image-based mine dust monitoring method. The monitoring method is characterized in that an open air chamber is adopted; an air pump and dust treatment equipment are not required; image acquisition equipment is used for acquiring a light source image; and dust monitoring is performed by using a difference value between an infrared light brightness value and a blue light brightness value. The interference of the sensitivity change of a color camera, mist and pollutants with the system monitoring value can be effectively restrained; zero setting and system sensitivity calibration are not required; high sensitivity is achieved; and convenience is brought to mounting and maintenance. The invention also provides a method for automatically cleaning a lens cover and a light source cover. Through adoption of the image-based mine dust monitoring method, the accuracy of system monitoring data is further ensured. The image-based mine dust monitoring method is particularlysuitable for a downhole dusty environment, and has the a wide application space.

Description

technical field [0001] The invention relates to an image-based mine dust monitoring method, 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 n...
