Accurate fire extinguishing system and method based on unmanned aerial vehicle and intelligent fire-fighting robot

Abstract

The invention discloses an accurate fire extinguishing system and method based on an unmanned aerial vehicle and an intelligent fire-fighting robot. The system comprises the intelligent fire-fightingrobot, an unmanned aerial vehicle take-off and landing platform, a fire fighting water cannon, a navigation attitude sensor, a GPS, the unmanned gyroplane, an infrared thermal imager, a dual-wavebandvisible light camera, a laser ranging sensor, a pan-tilt system and a remote monitoring terminal. The fire extinguishing method includes the steps that the unmanned gyroplane performs accurate positioning on a fire point and a jetting falling point in sequence through the GPS, the laser ranging sensor, the navigation attitude sensor, the pan-tilt system and an image processing technology; and theintelligent fire-fighting robot ceaselessly adjusts the course angle and the pitch angle of the fire fighting water cannon according to positioning information, and therefore the jetting falling pointcan accurately cover a fire point area, and closed-loop accurate fire extinguishing is formed. The accurate fire extinguishing system and method based on the unmanned aerial vehicle and the intelligent fire-fighting robot can solve the problems that the large-firing-range and large-outdoor-space intelligent fire-fighting robot is insufficient in vision space, not accurate in fire point positioning and not high in fire extinguishing precision and intelligent degree, and achieves closed-loop accurate fire extinguishing.

Description

technical field [0001] The invention relates to the technical field of firefighting equipment, in particular to a precise firefighting system and method based on unmanned aerial vehicles and intelligent firefighting robots. Background technique [0002] With the continuous development of intelligent fire-fighting robot technology, intelligent fire-fighting robots are more and more used in various accident rescue sites, and the range of intelligent fire-fighting robots is getting farther and farther. Existing intelligent fire-fighting robots mainly rely on image processing technology to achieve For the location of the fire source, some use the jet trajectory database to look up the table to adjust the fire monitor to the corresponding angle to extinguish the fire, and some use the jet trajectory model equation to adjust the fire monitor to the corresponding angle to extinguish the fire. Most of these databases and models are obtained in a certain experimental environment, and...
