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 ...

Embodiment Construction

[0020] According to the above-mentioned one, a four-axis aircraft is used for underground detection, including a UAV aircraft and a remote host computer. The UAV is equipped with a main controller, a flight controller, an obstacle avoidance system, an infrared auxiliary system, a miniature infrared camera, multiple Parameters Miniature gas sensor, temperature sensor, pressure sensor, and the main controller are respectively connected to infrared camera, infrared auxiliary system, relay unit placement module and various sensors; considering the poor communication effect in the mine roadway, this design adds a relay unit placement module , can carry micro-relay units and place relay units in the route to increase the downhole detection distance. Considering the complex structure of the underground roadway during the disaster period, this design incorporates an obstacle avoidance system, which can autonomously fly to the destination according to the pre-entered roadway information...
