Embodiment 1

[0120] Please refer to figure 1 As shown in Fig. 3, the present invention provides a method for avoiding collisions of three sorties of aircraft, including:

[0121] Step 1, according to the status information of the aircraft in the surrounding airspace and the status information of the target aircraft, obtain the distance between the target aircraft and any aircraft in the surrounding airspace;

[0122] Step 2, when there is an intruder aircraft in the surrounding airspace of the target aircraft, according to the comparison result of the distance between the target aircraft and the intruder aircraft when they reach the closest point and the distance threshold, and / or the target aircraft and the intruder aircraft The comparison result of the time of arriving at the closest point and the time threshold determines that two aircrafts conflict; when two aircrafts conflict occurs, the target aircraft and the intrusion aircraft execute the two aircrafts collision avoidance strategy;...

Embodiment 2

[0257] Corresponding to Embodiment 1, see Figure 16 , the embodiment of the present invention provides three sorties aircraft anti-collision system, including distance measurement module 1, two-aircraft anti-collision module 2, three-aircraft anti-collision module 3, return flight module 4, wherein:

[0258] The distance measurement module 1 is used to obtain the distance between the target aircraft and any aircraft in the surrounding airspace according to the status information of the aircraft in the surrounding airspace and the status information of the target aircraft;

[0259] The two-aircraft collision avoidance module 2 is used for when there is an intruder aircraft in the surrounding airspace of the target aircraft, according to the comparison result of the distance between the target aircraft and the intruder aircraft when they reach the closest point and the distance threshold, and / or the The comparison result of the time when the target aircraft and the intrusion ai...

Abstract

The invention discloses a three-aircraft collision avoidance method and system. The three-aircraft collision avoidance method comprises the steps that the distance between a target aircraft and any aircraft in a surrounding airspace is acquired according to the state information of aircrafts in the surrounding airspace and the state information of the target aircraft; when an intruder aircraft exists in the surrounding airspace of the target aircraft, a two-aircraft conflict is determined; in the event of the two-aircraft conflict, the target aircraft and the intruder aircraft perform a two-aircraft collision avoidance strategy; when a potential intruder aircraft exists in the surrounding airspace of the target aircraft, a three-aircraft conflict and the situation thereof are determined; in the event of the three-aircraft conflict, a three-aircraft collision avoidance strategy is selected according to the situation of the three-aircraft conflict; and after the three-aircraft collisionavoidance is completed by flying according to the direction and intensity specified by the three-aircraft collision avoidance strategy, a predetermined trajectory is returned. The three-aircraft collision avoidance method and system solve the problem of the three-aircraft conflict and realizes multi-aircraft collision avoidance.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and system for avoiding collisions of three sorties aircraft. Background technique [0002] The TCAS (Traffic Collision Avoidance System) system is widely installed in large aircraft such as civil aviation airliners, and is the last line of defense to avoid aircraft collisions in the air. The TCAS system obtains the position and speed information of the surrounding aircraft by broadcasting inquiries and receiving replies from nearby aircraft, and judges whether the nearby aircraft poses a threat to the target aircraft. When an intruder aircraft threatens the target aircraft, the TCAS system will issue a warning and guide the aircraft to avoid the conflict area through operational prompts. [0003] With the sharp increase in aviation demand, the volume of air traffic has increased significantly, and the surrounding airspace such as airports has also beco...
