A UAV fire extinguishing method based on the airspace division of high-rise building fire

Abstract

The invention discloses an unmanned aerial vehicle fire extinguishing method based on high-rise building fire airspace division. By dividing a fire extinguishing flying airspace over a floor on fire into a dangerous zone, a restricted zone and a safe zone, a fire-fighting unmanned aerial vehicle can not pass through the dangerous zone in the process from a takeoff point to the position over the floor on fire, and then it is guaranteed that the unmanned aerial vehicle safely arrives at the fire extinguishing airspace; amendment is conducted on the flying line of the unmanned aerial vehicle and the flying path of the unmanned aerial vehicle after fire extinguishing bombs are dropped by analyzing heat flow time-space distribution characteristics and influences of heat flow disturbance, therefore, the unmanned aerial vehicle can precisely arrive at the optimal dropping position, air-drop parameters, including the air-drop height of the fire extinguishing bombs, the air-drop angle of the fire extinguishing bombs and the flying speed of the unmanned aerial vehicle during air dropping of the fire extinguishing bombs, of the unmanned aerial vehicle can be determined, it is guaranteed that the fire extinguishing bombs accurately hit the fire point, and fixed-point fire extinguishing is achieved. The unmanned aerial vehicle fire extinguishing method is not limited by the height of the floor on fire of a high-rise building, is good in fire extinguishing effect and high in fire extinguishing efficiency and achieves the wide practicability.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle fire extinguishing method, in particular to an unmanned aerial vehicle fire extinguishing method based on high-rise building fire airspace division. Background technique [0002] With the rapid development of my country's economy and construction science and technology, high-rise buildings with dense population and complex structures are gradually increasing. At present, my country has about 280,000 high-rise buildings, of which about 3,000 are super high-rise buildings over 100 meters. High-rise buildings have more prominent fire hazards due to their many floors, complex functions, various equipment, and many combustible materials. Therefore, on the one hand, it is necessary to effectively prevent the occurrence of fire; on the other hand, when a fire occurs, how to control the development of the fire in a timely and effective manner, and even extinguish the fire at the initial stage of the fire, so...

Problems solved by technology

Although these patents design the system and equipment for UAV fire extinguishing, they have not considered the division of fire airspace, the impact of fire heat flow disturbance on UAV performance, unmanned trajectory planning, and the flight trajectory of fire extinguishing bombs. Accuracy and poor accuracy of fire extinguishing bombs hitting the fire point have seriously affected the efficiency of UAV fire extinguishing
