Underground goaf safety monitoring device and monitoring method based on Beidou satellite

Abstract

The invention discloses an underground goaf safety monitoring device and method based on a Beidou satellite. The device comprises an L-shaped plate, a vertical rod is fixedly connected to the top of the L-shaped plate, and a control box is fixedly mounted on the outer side of the vertical rod. The device is compact in structure, easy and convenient to operate and high in practicability; by arranging a safety monitoring camera capable of being adjusted in a lifting mode, the device can be conveniently adjusted and maintained, meanwhile, workers are prevented from climbing, potential safety hazards are greatly reduced, and by arranging the clamping mechanism, the safety monitoring camera can be rapidly disassembled and replaced, the disassembly and replacement efficiency is greatly improved, screws do not need to be screwed for multiple times, the phenomenon of screw slipping is avoided, the service life of equipment is greatly prolonged, in addition, by arranging a rotation adjusting mechanism and an angle adjusting mechanism, the orientation angle and the inclination angle of the safety monitoring camera can be rapidly adjusted, and the practical use is facilitated.

Description

technical field [0001] The invention belongs to the field of monitoring devices, in particular to an underground safety monitoring device and monitoring method for goafs based on the Beidou satellite. Background technique [0002] In existing life, China's Beidou satellite navigation system is a global satellite navigation system developed by China itself, and it is also the third mature satellite navigation system after GPS and GLONASS. It is a supplier identified by the United Nations Satellite Navigation Commission, and the goaf is a cavity created by man-made excavation or natural geological movement below the surface. The existence of the goaf makes the safe production of the mine face great safety problems. Personnel and machinery The equipment may fall into the goaf and be damaged, and monitoring the underground of the goaf is a necessary measure to ensure safety. It is also an existing technical solution to apply the Beidou satellite to the underground monitoring dev...

Problems solved by technology

[0003] However, most of the existing goaf safety monitoring devices based on Beidou satellite are directly installed on the wall of the underground cavity when they are in use. There are certain potential safety hazards in adjustment and maintenance. At the same time, when the existing Beidou satellite-based goaf safety monitoring devices are used, most of them are installed and fixed by screws. When it needs to be disassembled and replaced, many more Only by turning the screw once can it be disassembled and replaced, which not only reduces the efficiency of disassembly and replacement, but also easily causes the phenomenon of wire slipping when the screw is turned many times, which greatly reduces the service life of the equipment. At the same time, the existing Beidou-based When the satellite goaf underground safety monitoring device is in use, its orientation angle and inclination angle are mostly fixed and inconvenient, and cannot be adjusted quickly, which is not conducive to actual use
