Embodiment 1

[0037] This embodiment describes in detail the unattended automatic visual monitoring system for the excavation working face.

[0038] Such as Figure 1-Figure 7 As shown, the unattended automatic visual monitoring system for the driving face proposed in this embodiment includes a visual auxiliary system 201, a signal acquisition system 203 and a mine intrinsically safe display 107, wherein the visual auxiliary system 201 includes Intrinsically safe laser ray meter for mining near the coal wall of the tunneling face. The intrinsically safe laser ray meter for mining can project a visualized fan-shaped light to the coal wall of the tunneling face, and the visualized fan-shaped light forms a "door" on the coal wall of the tunneling face The schematic line of the font frame; the signal acquisition system, which includes several camera devices, and the shooting direction of the camera device is directed towards the coal wall of the excavation face, so as to obtain the image that t...

Embodiment 2

[0046] The unattended automatic visual monitoring method for the excavation working face uses the unattended automatic visual monitoring system for the excavation working face proposed in Embodiment 1, including using the visualization auxiliary system 201 to emit two vertical green laser rays 125 on both sides of the roadway, A horizontal green laser ray 125 is emitted from the roof of the roadway, and three green laser rays 125 in the shape of a "gate" are formed after being blocked by the coal wall of the excavation face; the video picture in front of the excavation face is transmitted wirelessly to the mine in real time through the signal acquisition system 203 With the intrinsically safe display 107, when the roadheader gun head 101 cuts to the edges of both sides of the excavation face, with the green laser ray 125 as a reference, it can be judged from the image displayed on the mine intrinsically safe display 107 that the coal has been cut. to the edge of the excavation ...

Abstract

The present invention relates to technology and method for unattended monitoring of excavation working face, in particular to an unattended automatic visual monitoring system for excavation working face, wherein the visualization auxiliary system includes mine-used intrinsically safe laser rays arranged in the excavation roadway close to the coal wall of the excavation working face The intrinsically safe laser ray meter for mining can project light to the coal wall, and the light forms a "gate"-shaped frame line on the coal wall of the tunneling face; the shooting direction of the camera equipment in the signal acquisition system faces the coal wall of the tunneling face , to obtain the image that the roadheader has cut coal to the edge position of the tunneling face and the schematic line of the frame; the intrinsically safe display for mining is connected to the signal acquisition system signal, and the intrinsically safe display for mine is used to display the signal acquisition system The captured image signal. This system provides an accurate reference for the accuracy of the driving direction, which can well solve the above-mentioned problem of poor calibration accuracy, and at the same time, it can keep the camera system to continuously obtain clear images of underground work.

Description

technical field [0001] The invention relates to an unattended monitoring technology and method for an excavation face, in particular to an unattended automatic visual monitoring system and a monitoring method for an excavation face. Background technique [0002] For the excavation face of the outburst coal seam, the probability of gas outburst or large coal mass injection and injury accidents is the highest. In recent years, with the development of the coal industry, the degree of automation has become higher and higher. However, in the excavation face, because of the extremely harsh environment during the excavation process, it is still impossible to realize the unattended excavation process. The main difficulty lies in the inability to realize automatic visual monitoring. Measures, even if the control and hydraulic system of the roadheader can reach the level of remote control, due to the lack of the "eyes" of automatic remote monitoring, it is equivalent to "blind mining"...
