Embodiment 2

[0037] Operation process of mine disaster search and rescue and toxic and harmful gas monitoring system based on obstacle avoidance UAV:

[0038] After the mine disaster occurs, the search and rescue personnel carry the user monitoring terminal 1, the obstacle avoidance drone and the toxic and harmful gas monitoring flight platform 2 to the nearest safe area of ​​the mine disaster. Start the take-off device of the obstacle-avoiding UAV to ensure the normal take-off of the UAV; after receiving the take-off and destination instructions sent by the user monitoring station PC 1-1 through the wireless modem 1-3 when the take-off environment is confirmed to be good, the obstacle avoidance UAV flight search and rescue and monitoring platform 2 starts navigation and flight control integrated system 2-3 and obstacle avoidance subsystem 2-8 to fly to the mine destination, and 4 motor blade assemblies 2-2 receive navigation and flight control integration The control signal sent by the au...

Embodiment 3

[0042] Step a, the search and rescue personnel carry the user monitoring terminal (1) and the obstacle avoidance UAV search and rescue and toxic and harmful gas monitoring flight platform (2) to a safe area near the mine accident, and start the UAV flight platform (2-1);

[0043] Step b, send a take-off command, turn on the integrated navigation and positioning and flight control system (2-3) and the obstacle avoidance subsystem (2-8), the operator combines the video information collected by the high-definition camera and the searchlight (2-9-2) and The obstacle avoidance subsystem (2-8) controls the RC controller (1-3) to ensure the safe flight of the UAV in the mine;

[0044] Step c, turn on the toxic and harmful gas monitoring system (2-4) and the thermal imaging camera (2-9), and the unmanned aerial vehicle searches and advances and flies to the mine disaster area;

[0045] Step d, real-time collection of thermal imaging information around the mine disaster area, toxic and...

Abstract

The invention discloses a mine disaster search and rescue and toxic and harmful gas monitoring system and working method based on an obstacle-avoiding unmanned aerial vehicle, belonging to the field of coal mine roadway emergency search and rescue. The system of the present invention includes two parts, the user monitoring terminal and the unmanned aerial vehicle flight platform. Among them, the user monitoring terminal realizes the effective control of the UAV and the return of the information collected by the airborne sensor, and the UAV flight platform is tested by carrying instruments. When a mine disaster occurs, the search and rescue personnel activate the system in the nearest safe area to collect image information, infrared imaging information and toxic and harmful gas parameters near the flight area in real time under the premise of ensuring the safe flight of the drone, and send them back to the user monitoring terminal in real time. When human body imaging information or toxic and harmful gas information is detected, corresponding search and rescue can be quickly carried out. The invention solves the technical problems of the traditional unmanned vehicle mine disaster search and rescue and roadway monitoring system, which have low obstacle surmounting ability, slow search speed, and space-limited working range.

Description

technical field [0001] The invention belongs to the field of emergency search and rescue in coal mine roadways, and in particular relates to a mine disaster search and rescue and poisonous and harmful monitoring system based on an obstacle avoidance drone and a working method thereof. Background technique [0002] At present, the commonly used mine disaster search and rescue and mine toxic and harmful gas monitoring systems mainly include: hand-held monitors, search and rescue dogs, mobile robots, etc. At present, the traditional search and rescue and monitoring systems have low obstacle surmountability, slow search speed, and limited working range. It is not conducive to the rapid and effective search and rescue after the mining disaster occurs. [0003] For example: when a mine disaster occurs, search and rescue personnel and search and rescue dogs cannot directly enter the mine, and the environment in the mine is unknown, so the safety of search and rescue personnel and s...
