Multi-aircraft conflict detecting-extricating method and system of complex low-altitude flight

Abstract

The invention discloses a multi-aircraft conflict detecting-extricating method and system of complex low-altitude flight. The method comprises that a present flight parameter and relative position relation between any two aircrafts are obtained; a potential conflict set and a gathering conflict set are determined according to the present flight parameter; a multi-aircraft flight conflict extricating model is established according to the relative position relation; present flight states of the aircrafts are obtained; a conflict extricating group is determined according to the present flight states, the potential conflict set and the gathering conflict set; and the aircrafts in the conflict extricating group are input to the multi-aircraft flight conflict extricating model in the descendingorder of the extricating priority, and conflict avoidance behaviors are determined. Via the method and system, a pilot can be provided with a conflict avoidance decision under the condition that the pilot cannot complete safe and efficient flight completely relying on autonomous behaviours.

Description

technical field [0001] The invention relates to the field of multi-aircraft conflict detection and resolution, in particular to a complex low-altitude flight multi-aircraft conflict detection and resolution method and system. Background technique [0002] Low-altitude airspace is an important part of my country's airspace system, which contains great economic and social value. With the increasing demand for low-altitude flights, making full use of low-altitude resources and scientifically controlling low-altitude flights has become an important issue facing the world's aviation powers. General aviation activities are organized in a variety of ways, and there are many types of flight activities. Flight operations are usually carried out at low or ultra-low altitudes. They are highly dispersed, with many points, lines, and wide areas. They are vulnerable to bad weather, ground obstacles, military flight activities, flying birds and The impact of various random factors such as...
