Coal mine underground unmanned aerial vehicle tunnel inspection system

Abstract

The invention discloses a coal mine underground unmanned aerial vehicle tunnel inspection system, which comprises an unmanned aerial vehicle inspection subsystem, an information transmission subsystemand a bottom surface control subsystem, and the unmanned aerial vehicle inspection subsystem comprises a flight control unit, an external load instrument unit, an obstacle avoidance and distance measurement unit, an image acquisition unit, a voice broadcast unit and a gas monitoring unit. The purpose of conveniently adapting to the complex terrain of the roadway is achieved, the effect of conveniently conducting more effective routing inspection on the roadway is achieved, the personal safety of personnel is guaranteed, the purposes of underground personnel reduction and efficiency improvement are achieved, the intelligent level of mine roadway routing inspection is improved, and the effect of controlling an underground unmanned aerial vehicle to conduct routing inspection on the roadwayin real time is achieved. The low-delay transmission effect of the underground unmanned aerial vehicle inspection data image is achieved, the inspection efficiency is improved for real-time monitoringof an underground roadway of a coal mine, the effect of conveniently and comprehensively checking potential safety hazards in the roadway is achieved, and the safety risk in the roadway is reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine underground inspection technology, in particular to an unmanned aerial vehicle roadway inspection system for underground coal mines. Background technique [0002] The roadway is a variety of passages drilled between the surface and the ore body, which are used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparations for new excavation of ore for metallurgical equipment. These passages are collectively referred to as roadways. . In order to mine coal safely and efficiently, coal mine inspection is an important means and measure to eliminate hidden dangers, prevent accidents, and ensure safe production in coal mines. [0003] At present, most of the underground coal mines are inspected manually, and some qualified mines may be equipped with inspection robots. There are human safety risks and low efficiency in the manual inspection process, and it is difficul...
