Collision conflict detection method and system

Abstract

The invention provides a collision conflict detection method and system. The system comprises an ADS-B receiver, an upper / lower omnidirectional antenna, a decoding module, a trajectory processing module and a threat detection module. For an ADS-B target near a host aerial carrier, at least two stages of collision conflict zones are established. Collision conflict is predicted based on the motion parameters of the host aerial carrier and a target aircraft. The motion parameters include speed, the heading and the turn rates of the host aircraft and the target aircraft. Compared with the prior art, collision conflict threat detection can be performed independently based on ADS-B message information. The system can be integrated with ACAS equipment, and can also be independently applied to general aviation aircrafts, unmanned aerial vehicles, and helicopters without ACAS equipment so as to improve flight safety in airspace.

Description

technical field [0001] The invention relates to a collision detection method and system based on the real-time position message of an aircraft, which is suitable for the field of air traffic control collision avoidance. Background technique [0002] Most of the current military and civil aviation aircraft are equipped with airborne collision avoidance systems. The new S-mode transponder realizes the air traffic control response function and also has the ADS-B OUT function, which can broadcast the flight ID, real-time position, and altitude of the aircraft to other aircraft in real time. information. The following is an introduction to the functions of the airborne collision avoidance system and ADS-B. [0003] Airborne Collision Avoidance System (ACAS: Airborne Collision Avoidance System) has been in existence for more than 30 years. It is defined by the Federal Aviation Administration (FAA) and is an essential device to prevent dangerous approach and collision accidents of...

AI Technical Summary

Problems solved by technology

[0005] The existing airborne collision avoidance system makes limited use of ADS-B information, and cooperates with the secondary radar active interrogation to realize hybrid surveillance, which is used for air-to-air target surveillance at long distances or when there is no threat of collision, which can enhance surveillance stability; at the same time It can reduce the number of active inquiries, thereby reducing space electromagnetic radiation, but the current equipment cannot independently perform threat detection based on ADS-B message information, and generate alarm enhancements

Therefore, for general aviation aircraft, UAVs, helicopters and other aircraft that are not equipped with ACAS equipment, they do not have the capabilities of onboard autonomous threat detection and anti-collision enhancement.
