Quadrocopter-based detection device during mine disaster period

Abstract

The present invention relates to the unmanned aerial vehicle-based environment detection technology and a method thereof during the mine disaster period. During the mine disaster period, such as the period of the gas outburst, the gas explosion, the fire disaster, the water inrush and other accidents in a mine, people cannot get into the mine, and an emergency rescue headquarter cannot evaluate the underground environment. In the prior art, a quadrocopter and an underground wireless positioning system are combined to realize the flight control and the data transmission of an unmanned aerial vehicle. The unmanned aerial vehicle is provided with a miniature infrared camera, a multi-parameter micro gas sensor, a temperature sensor, and a pressure sensor. The monitoring data of the onboard camera and multiple sensors can be recorded in a built-in storage. The unmanned aerial vehicle is provided with a micro self-contained power supply relay unit arranged along the detection line. The relay unit is compatible with an underground communication system and an unmanned aerial vehicle communication system, so that the communication transmission distance of the unmanned aerial vehicle is prolonged. Data stored in the storage are transmitted back to the ground through a wireless communication system. Therefore, disaster-relief basic parameters are provided.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring during a coal mine catastrophe, in particular to a mine disaster detection device based on a four-axis aircraft. Background technique [0002] At present, drones have been widely used in aerial photography, agriculture, forestry, fire, monitoring and early warning. The miniaturization, high mobility and portability of drones have shown very high adaptability in the above fields. Underground disasters in coal mines include accidents such as coal and gas outburst, gas explosion, and water inrush. Once an accident occurs, the communication facilities are damaged, and the underground power outage measures are taken. The underground roadway, equipment damage and air environment cannot be known. The safety and security of rescuers poses a huge challenge. The current underground accident rescue generally depends on the professional knowledge and experience of experts to judge, evaluate ...

AI Technical Summary

Problems solved by technology

[0006] At present, the performance of underground wireless communication is poor, especially during the coal mine disaster period, the original underground communication system is difficult to use, and obstacles in the roadway further shorten the communication distance of the robot
