Unmanned plane active threat avoiding system based on air traffic control data link

Abstract

The invention discloses an unmanned plane active threat avoiding system based on an air traffic control data link. The unmanned plane active threat avoiding system is applied on an airborne-end of an unmanned plane and comprises a radio frequency transmit-receive module and a situation perception and avoiding processing host, wherein the radio frequency transmit-receive module is configured to receive ADS-B information, of an adjacent plane, sent by a ground terminal and other airplanes, and the situation perception and avoiding processing host obtains angle, distance, height and time stamp of an adjacent plane according to the ADS-B information of the adjacent plane and ADS-B information of the unmanned plane, evaluates the threatening level according to the angle, distance, height and time stamp of the adjacent plane, and sends the angle, distance, height and time stamp of the adjacent plane to the ground end through an unmanned plane data link. The unmanned plane active threat avoiding system provides flying situation sensing and emergency active threat avoiding suggestion of cooperative planes in a nearby spatial domain for a ground station by using limited assembling condition of an unmanned plane, thereby effectively improving comprehensive air situation sensing capability, active safety space retaining capability and active conflict solving capability of an unmanned plane operation area.

Description

technical field [0001] The invention belongs to the technical field of aviation, and relates to a hybrid monitoring method for the fusion of ADS-B technology and TCAS system; Background technique [0002] The anti-collision of aircraft in the air is to grasp the flight dynamics through the ground air traffic control monitoring equipment, and rely on the air traffic control system to deploy flight conflicts. In order to avoid mid-air collisions, manned aircraft are also equipped with airborne collision avoidance systems and ADS-B systems. Among them, the airborne collision avoidance system can independently complete the anti-collision warning without relying on the ground air traffic control; the ADS-B system can independently obtain the flight status of other aircraft equipped with the ADS-B system in the airspace without relying on the ground air traffic control. UAVs do not have corresponding technical means, and currently rely entirely on isolated airspace operations to ...

UAVs do not have corresponding technical means, and currently rely entirely on isolated airspace operations to prevent air collisions with military and civilian aviation manned aircraft

[0003] With the gradual deepening of the opening of low-altitude airspace, the number of aerial vehicles will increase greatly, and the pressure of airspace density will make it difficult to plan isolated airspace for drones to operate independently. Drones will inevitably need to visit the national airspace system frequently, and low-altitude operations will be unmanned. The probability of collision between aircraft and general aviation aircraft will also be greatly increased, and there will be huge safety hazards.
