Unmanned aerial vehicle cluster formation flight method for saving communication bandwidth

Abstract

The invention relates to an unmanned aerial vehicle cluster formation flight method for saving communication bandwidth, which comprises the following steps that: a computer control program for processing strategy information and long and short messages of a long aerial vehicle in formation flight is pre-integrated in each unmanned aerial vehicle Fi in an unmanned aerial vehicle cluster based on an ad hoc network link; when the unmanned aerial vehicle Fi receives the long and short messages shared by other unmanned aerial vehicles Fj, the unmanned aerial vehicle Fi checks that the own identifier is the same as the long aerial vehicle identifier in the long and short messages, and the long aerial vehicle processes the strategy information and updates the own level information and shares the long message at the same time; the long message is message information which has position information and is shared by a lead aircraft, and the short message is message information which does not have position information and is shared by unmanned aerial vehicles as wing aircrafts. According to the method provided by the invention, the unmanned aerial vehicle can flexibly switch the long unmanned aerial vehicle, send the position as required and dynamically use the bandwidth, so that the sharing of invalid data is avoided, and the technical problems that the networking communication link is poor in stability and the communication bandwidth is occupied in the prior art are effectively solved.

Description

technical field

[0001] The present invention relates to an ad hoc networking technology for unmanned aerial vehicle clusters, in particular to an unmanned aerial vehicle cluster formation flight method for saving communication bandwidth and unmanned aerial vehicles. Background technique

[0002] UAV formation flight means that multiple UAVs maintain a designated formation flight in the air. At present, there are three main technical solutions for UAV formation flight. The first is to control the position of each UAV flying in the air through a one-to-many ground-to-air communication link; the second is to designate one of the drones in the cluster. The UAV is the leader, and the other UAVs are the wingmen. The leader sends its position to the wingman through a one-to-many link in the air, and the wingman automatically follows the leader after obtaining the position of the leader; the third is the designated cluster One drone is the lead plane, and the rest are wingmen.
