Abstract

The present invention relates to a formation flying method for swarms of unmanned aerial vehicles for saving communication bandwidth. i It is pre-integrated with a computer control program for the long aircraft in formation flight to process strategy information and long and short messages. When the UAV F i Other UAV F received j For shared long and short messages, check that its own ID is the same as the long machine ID in the long and short messages. At the same time, the long machine processing policy information updates its own level information and shares the long message; the long message has location information and is shared as the long machine. The message information of the short message is the message information without location information shared by the UAV as a wingman. In the method of the invention, the UAV can flexibly switch the long plane, send the position on demand, dynamically use the bandwidth, avoid the sharing of invalid data, and effectively solve the problems of poor stability of the network communication link and occupied communication bandwidth in the prior art. technical problem.

Description

technical field

[0001] The invention relates to the self-organizing network technology of unmanned aerial vehicle swarms, in particular to a formation flying method of unmanned aerial vehicle swarms and unmanned aerial vehicles for saving communication bandwidth. Background technique

[0002] UAV formation flight refers to the flight of multiple UAVs in the air in a designated formation. At present, there are three main technical solutions for UAV formation flight. The first is that the ground controls the position of each UAV in the air through a one-to-many ground-to-air communication link; the second is to designate one of the swarms. The drone is the leader, and the other drones are 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 leader's position; the third type is the designated cluster. One UAV is the lead plane, and the other UAVs are wingmen. All UAVs s...
