Aircraft active discovery and cooperative anti-collision method and system

Abstract

The invention discloses an aircraft active discovery and cooperative anti-collision method and system, and relates to the field of multi-aircraft cooperation. According to the method aimed at a multi-aircraft common-domain flight scene, each aircraft predicts four-dimensional information of a future short-time flight path through existing information, active information sharing is realized betweenadjacent aircrafts, and cooperative collision prevention and cooperation ability evaluation are achieved. The method comprises the steps of future short-time flight line information prediction and broadcasting, broadcast receiving and space conflict analysis and avoidance, and collision avoidance returning. The system comprises a flight path and state recording module, a future short-time flightpath prediction module, a broadcast sending module, a broadcast receiving module, a space conflict analysis module, a conflict avoidance decision processing module, a cooperation ability evaluation module and a collision avoidance return decision processing module. The method and system have the advantages of high real-time performance, low calculation cost, low cost, more aircrafts accommodated in the same airspace and the like.

Description

technical field [0001] The invention relates to the technical field of multi-aircraft cooperation, in particular to a multi-aircraft active discovery and cooperative anti-collision method and system. Background technique [0002] The development of aviation technology makes low-altitude flight and ultra-low-altitude flight more and more common. Different from high-altitude and ultra-high-altitude flight, low-altitude flight has low altitude and high relative speed to the ground, and has high requirements for aircraft operation and control: short processing time and small processing error. Therefore, autonomous flight control or auxiliary flight control is very important to improve the maneuverability and safety of low-altitude aircraft. [0003] Anti-collision handling is an important part of autonomous flight control or assisted flight control. Typical examples of existing anti-collision systems, such as those for drones or robots, mainly focus on avoiding static obstacle...

AI Technical Summary

Problems solved by technology

Each active detection technology has its own characteristics and technical problems, such as visual detection is limited by visible light, the observation distance is limited, and it is only suitable for low-speed aircraft; radar detection is heavy, costly, and complex to operate

The multi-type sensor data fusion technology is immature, resulting in incomplete real-time dynamic perception of the environment by the aircraft, and each aircraft independently makes avoidance decisions, making collisions between aircraft still inevitable
