A trajectory planning method for emergency search and rescue under the coordination mechanism of unmanned aerial vehicles and manned vehicles

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...

AI Technical Summary

Problems solved by technology

However, my country's existing aviation emergency rescue operating regulations and emergency rescue programs are not perfect, resulting in low rescue efficiency and the danger of rescuers facing unknown environmental threats after the disaster, making the safety of search and rescue unable to be guaranteed.

Taking the earthquake in Wenchuan City, Sichuan Province on May 12, 2008 as an example, the Civil Aviation Administration of China mobilized a total of more than 30 rescue helicopters from Eastern General Aviation, China Southern Airlines Zhuhai Helicopter Branch, etc. to carry out rescue work. The terrain and environment in the disaster area are complex, the weather conditions are poor, the flight information preparation is insufficient, the disaster situation in the hardest hit area, and the rescue goals are not clear, which leads to the slow progress of the rescue mission and poor safety, etc.
