Abstract

The invention discloses a multi-plane multi-object emergent search-and-rescue flight path planning method under a cooperation mechanism of unmanned planes and manned planes for the first time. The method comprises following steps: step one, searching a disaster-affected area by multiple unmanned planes to obtain suspected locations, where disaster-affected people stay; step two, based on the suspected locations, planning an optimal flight path for the unmanned planes to search the suspected locations, based on the optimal flight path, and exerting a pre-arranged plan that uses multiple unmanned planes to search the suspected locations to obtain the locations where disaster-affected people stay and number of disaster-affected people; and step three, based on the locations and number of disaster-affected people, planning an optimal flight path for emergent search-and-rescue of multiple manned planes, and based on the optimal flight path, exerting an emergent search-and-rescue pre-arranged plan assisted by multiple manned planes. The method can effectively improve the efficiency and safety of emergent search-and-rescue in mountain areas of China, is suitable for various flight environments in mountain areas, and guarantees the safety of rescue flight.

Description

technical field

[0001] The invention relates to the technical field of aviation emergency rescue in mountainous areas, in particular to aviation emergency search and rescue track gauge technology under mountainous conditions of major natural disasters (such as earthquakes, mud-rock flows, etc.), and in particular to a method that can effectively improve emergency rescue in mountainous areas of our country. Efficiency and safety, and can flexibly respond to different mountainous flight environments to provide rich rescue preparations for unmanned aerial vehicles and a multi-aircraft multi-target emergency search and rescue trajectory planning method under the man-machine coordination mechanism. Background technique

[0002] After the occurrence of major natural disasters in mountainous areas, aviation emergency rescue based on civilian drones and general aviation manned aircraft has the advantages of speed, efficiency, low risk, low secondary injury rate, and less geographical...
