Problems solved by technology

[0008] The technical problem to be solved by the present invention is: the current airborne collision avoidance system (ACAS X) cannot generate a decisive alarm (RA) to the ADS-B target, and does not possess the RA coordination capability of the ADS-B target. On-board collision avoidance system is improved on the basis of the existing ACAS X, and a decision-warning coordination module is added to solve the above technical problems through the decision-warning coordination module and corresponding actions

Embodiment 1

[0050] This embodiment provides an airborne collision avoidance system, including a monitoring and warning module, the monitoring and warning module is used to monitor the response targets around the system carrier aircraft and generate an alarm; it also includes a decisive warning coordination module;

[0051] The determination alarm coordination module generates a determination alarm to the ADS-B response target, and performs alarm coordination with the ADS-B response target based on the determination alarm.

[0052] The system-carrying aircraft is equipment loaded with an airborne anti-collision system.

[0053] The ADS-B transponder is an ADS-B equipped transponder equipped with a Mode S transponder.

[0054] The monitoring and warning module continuously monitors the ADS-B response target, and calculates through the collision avoidance algorithm. When the distance between the ADS-B response target and the system carrier aircraft exceeds a preset threshold, the decision wa...

Embodiment 2

[0067] On the basis of the previous embodiment, if figure 2 As shown, during the alarm coordination process between the decisive alarm coordination module and the ADS-B response target, the workflow of the ADS-B response target includes:

[0068] S1. The broadcast system carries the DF17 message of the aircraft itself, and passively waits to receive the DF17 message of the cooperative decision alarm;

[0069] S2. After receiving the DF17 message of the cooperative decision warning, broadcast and confirm the cooperative information;

[0070] S3. Perform maneuvers according to the requirements of the DF17 message of the cooperative decision warning;

[0071] S4. Waiting for receiving the coordination termination information, terminating the coordination action after receiving the coordination termination information, and returning to step S1 to resume normal flight.

[0072] Step S4 also includes:

[0073] In the case that the cooperation termination information is not recei...

Abstract

The invention discloses an airborne collision avoidance system, which generates a decision alarm based on a decision alarm collaboration module and an ADS-B response target, and realizes alarm collaboration with the ADS-B response target. In addition to the inherent capability of ACAS X, the system is mainly characterized in that when a monitored ADS-B response target generates collision threat, a traffic alarm and a decision alarm can be generated, and an existing ACAS X monitoring and anti-collision alarm method is used for generating a decision alarm (RA) for the ADS-B response target; when a decision alarm is generated, alarm cooperation with an ADS-B response target is realized, compatibility of maneuvering flight avoidance actions is maintained through cooperation, and compatibility, safety and effectiveness of vertical maneuvering flight directions of the ADS-B response target and the ADS-B response target are ensured.

Description

technical field [0001] The invention relates to the technical field of air traffic control, in particular to an airborne collision avoidance system. Background technique [0002] Air Traffic Alert and Collision Avoidance System (TCAS, Traffic Alert and Collision Avoidance System, ICAO equivalent term ACAS, Airborne Collision Avoidance System) is defined by the US Federal Aviation Administration (FAA), mainly used to prevent aircraft from colliding with aircraft. TCAS does not depend on the ground control system, and can provide Traffic Advisory (TA) and Resolution Advisory (RA). It is mainly used to provide aircraft with a safe distance between flights in the air. The system uses secondary radar to detect approaching aircraft in nearby airspace. Necessary , the pilot is reminded to take evasive measures to maintain a safe distance from other aircraft and achieve the purpose of collision avoidance. Years of flight practice have proved that this system is the last barrier to ...
