Problems solved by technology

Such a process may take tens of minutes, which is a very wasteful thing for a belt conveyor with huge power consumption, which is equivalent to exchanging high power consumption for high safety.

Embodiment Construction

[0061] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0062] Grayscale: Use black and white tones to represent objects, that is, use black as the reference color and black with different saturations to display images (the maximum value is 255 for white, the minimum value for 0 is black, and the value in between is gray).

[0063] Such as Figure 1 to Figure 6 Shown, a kind of coal flow identification method in the transport belt based on video surveillance of the present invention, comprises the following steps:

[0064] S1. System construction: In the initial situation, a camera needs to be installed. The camera is required to be able to capture a complete belt transportation surface relatively clearly, so as to ensure norm...

Abstract

The invention relates to the technical field of coal flow recognition. The invention relates to a conveyor belt, in particular to a method and system for identifying coal flow in the conveyor belt based on video monitoring. ANALYSIS BY REAL-TIME VIDEO PICTURE, a belt picture in the video picture is extracted and separated from coal in the belt; according to the coal flow detection method, the coalflow detection device and the coal flow detection system, extraction of coal flow pictures is achieved, the real-time coal flow is visually and clearly displayed to a user, in the process, abnormal behaviors such as belt deviation and sudden overexposure can be recognized, the real-time width of the coal flow can be displayed, and overload and no-load behaviors can be simply and visually detected; the method comprises the following steps that S1, a system is built; s2, acquiring a real-time picture; s3, extracting and converting an analysis area; s4, performing image sharpening processing; s5, texture extraction; S6, coal-belt separation; s7, calculating a coal flow proportion; and S8, overload and no-load recognition.

Description

technical field [0001] The invention relates to the technical field of coal flow identification, in particular to a method and system for identifying coal flow in a transport belt based on video monitoring. Background technique [0002] Coal is one of the indispensable energy sources. It plays an important role in my country's economic development. At present, the national economy is developing rapidly, and coal accounts for about 70% of the total energy consumption structure. In related national research reports, it is pointed out that by 2050, the total consumption of coal will account for more than 50% of all energy consumption. The above data show that for a long time, my country's energy consumption will still rely on coal resources. Because the rapid development of the national economy requires a large amount of coal and continuous large-scale mining of coal, the country is very concerned about the safe mining of the coal industry [0003] As the demand for coal mine...
