A remote visual monitoring method for unmanned mining face

Abstract

The invention discloses a remote visual monitoring method for an unmanned mining working face, which belongs to the technical field of coal mining automation. The invention builds a real-time data exchange platform to realize reliable real-time exchange of data; establishes a three-dimensional model of the working face and various The equipment model realizes the dynamic rendering of the 3D virtual scene of the working face, the posture simulation and remote control of the mining equipment, and the synchronous display of the monitoring video and the 3D virtual scene of the working face; establishes the underground disaster prediction and early warning model and the equipment fault diagnosis model to carry out disaster prediction and early warning and equipment fault diagnosis. Based on real-time data exchange, the present invention combines video surveillance technology with virtual reality technology, overcomes the factors that affect the line of sight such as water and fog on the mining face and the limitations of the camera itself, and combines the precise three-dimensional model of the mining area and real-time The monitoring data is used for underground disaster prediction and early warning, and equipment fault diagnosis, which has laid a good foundation for the comprehensive and truly unmanned mining face.

AI Technical Summary

Problems solved by technology

[0005] 1. There are often water, fog, dust and other factors that affect the line of sight in the mining face. In addition to the limitations of the camera itself, the camera cannot obtain clear and all-round images, let alone the interior of coal and rock masses, goafs, and mining equipment. information;

[0006] 2. The surface image obtained by monitoring video alone cannot fully and accurately judge the situation of underground disaster warning;

[0007] 3. It is impossible to accurately judge the operation status of the production equipment only by the surface image obtained by the surveillance video
