Abstract

The invention provides a dust concentration intelligent video sensor and a dust concentration detection method. The dust concentration intelligent video sensor comprises a video acquisition device anda dust concentration detection device. The dust concentration detection device comprises a laser generation device used for emitting laser, a conversion device used for converting laaser scattered bythe dust into a digital information signal, and a processing device used for generating a dust concentration value according to the digital information signal. According to the invention, a video acquisition device and the dust concentration detection device are combined, and a surrounding environment video which is acquired by the video acquisition device, and a dust concentration value detectedby the dust concentration detection device are transmitted and displayed together so that long-time continuous real-time output and display of combining dust concentration value data and video imagedata are realized; and the dust concentration under the mine can be observed more intuitively. Furthermore, the dust concentration detection device disclosed by the invention adopts an emission laser,a conversion device and a processing device, and realizes high-sensitivity detection on the dust concentration under the mine by utilizing a laser scattering principle.

Description

technical field [0001] The invention relates to the technical field of dust concentration detection, in particular to a dust concentration intelligent video sensor and a dust concentration detection method. Background technique [0002] Coal mine dust is a general term for fine particles of various solid substances produced in the production process of coal mines. Coal mine dust not only affects the health of construction workers, but also the dust suspended in the air will produce violent oxidation reaction when encountering high temperature, resulting in coal dust explosion, which seriously affects mine safety. Therefore, it is very important to develop a high-performance dust detection device. The existing technology only detects a single dust concentration value, and cannot realize the combination of dust concentration value data and video image signal data. Contents of the invention [0003] According to the first aspect of the embodiments of the present invention, ...
