Air traffic collision avoidance method based on state prediction

Abstract

The invention discloses an air traffic collision avoidance method based on state prediction. The method comprises the following steps: continuously detecting motion state information of all current planes in a local air space through a native plane; calculating the flight condition of all the planes in a specified length of time in the future according to the motion state information of all the planes, and screening out a target plane approaching the native plane; judging whether the target plane and the native plane pose a conflict risk, and sending traffic alert information if there is a conflict risk; and judging whether the target plane and the native plane posing a conflict risk pose a collision threat, and sending decision warning information and providing a collision avoidance decision if there is a collision threat. According to the invention, the flight condition of all the planes in a specified length of time in the future is observed continuously, a target plane approaching the native plane is screened out, whether the target plane and the native plane pose a conflict risk or a collision threat is judged, and a collision avoidance decision is provided. Thus, the probability and frequency of flight conflict are reduced effectively, and the safety of flight is ensured.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an air collision avoidance method based on state prediction. Background technique [0002] With the rapid development of the aviation industry, the air traffic density is increasing day by day. In order to ensure the safe and orderly flight of the aircraft, it is necessary to provide pilots with a reliable and maneuverable system based on the traditional Air Traffic Control (ATC) system. anti-collision measures. Under the condition of limited airspace resources, the consequences of the surge in flight volume are mainly manifested in two aspects: on the one hand, local airspace is congested, causing a large number of flight delays, causing huge economic losses and adverse social impacts on airlines; on the other hand, flight conflicts The increase in frequency has caused the relevant air traffic services and security systems to operate at high loads, and the security situation is not opti...
