Embodiment 1

[0057] Such as figure 1 as shown, figure 1 It shows a schematic flow chart of the UAV cluster formation flight method for saving communication bandwidth provided by an embodiment of the present invention. The method of this embodiment may include the following steps:

[0058] S10. The unmanned aerial vehicle cluster based on the ad hoc network link is flying in formation, and each unmanned aerial vehicle F i According to the state of the communication link between itself and the leader at the current moment, the preset leader processing strategy determines the identity of the leader used to follow the flight.

[0059] For example, if there is a drone F in the drone cluster i If the first type of message shared by the lead aircraft that is currently following the flight cannot be received, the lead aircraft processing strategy is used to determine a new lead aircraft identifier for following the flight.

[0060] S20, each UAV F i Share the message carrying the identificatio...

Embodiment 2

[0077] The embodiment of the present invention provides a UAV cluster formation flight method for saving communication bandwidth. The execution subject of this embodiment can be each UAV in the UAV cluster, which belongs to the technical solution of the first embodiment A further refinement of or another specific implementation. The method of this embodiment can be described in detail as follows:

[0078] The unmanned aerial vehicle swarm based on the ad hoc network link is flying in formation, based on the communication bandwidth saving rule, the unmanned aerial vehicle currently serving as the leader in the unmanned aerial vehicle swarm shares the first type of report according to the first preset time length. In the text, the UAV currently serving as a wingman sends the second type of message according to the second preset time length, so as to avoid the unstable state of communication in the ad hoc network link;

[0079] The communication bandwidth saving rule is a commun...

Embodiment 3

[0094] This embodiment proposes a technical solution for formation flight for UAV clusters with limited network communication bandwidth and unstable communication. combine Figure 2 to Figure 5 As shown, this embodiment is an initialization process of defining or establishing the strategy or rules in the computer program before the UAV cluster flies in formation. After the initialization is completed, the above-mentioned embodiment 1 and embodiment 2 can be realized. According to the technical solution, the process before initialization in this embodiment is as follows.

[0095] The following Q01 to step Q05 belong to the initialization process of the UAV cluster before the formation flight, and the initialization process can be realized by the host computer of the UAV cluster, or individually configured for the equipment required by each UAV.

[0096] Q01. When building a drone cluster, you can install a networking link for each drone in the drone cluster; by building an ad ...

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. All ...
