Embodiment Construction

[0026] The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0027] The orientation terms such as up, down, left, and right in this specification and claims are combined with the drawings for further explanation, making this application easier to understand, and not limiting this application. In different scenarios, up and down, left and right, and inside and outside are all Relatively speaking.

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

Abstract

The invention discloses a distributed unmanned aerial vehicle formation change method, relates to the technical field of unmanned aerial vehicle flight, solves the problems of high communication overhead and low reliability of formation change information transmission and the problem of distributed formation synchronization, and enhances the safety of distributed formation change. According to thespecific scheme, the method comprises the following steps: S1, presetting related instructions of all formation patterns on all unmanned aerial vehicles, and sequentially performing numbering according to the number of the formation patterns; s2, sending serial number signals of the formation needing to be changed to all the unmanned aerial vehicles through a control station; s3, enabling all theunmanned aerial vehicles to receive the serial number signals in the S2, automatically generating a leader plane according to instructions of the unmanned aerial vehicles in the S1, wherein the otherunmanned aerial vehicles are wing planes; and S4, enabling the lead aircraft to adjust the position of the lead aircraft according to the instruction of the lead aircraft, and enabling all the wing aircrafts to adjust the positions of the wing aircrafts according to the instruction of the lead aircrafts. According to the invention, the idea of instruction number mapping formation is adopted, so that the communication overhead caused by directly sending the formation matrix can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, and more specifically, it relates to a method for transforming formations of distributed unmanned aerial vehicles. Background technique [0002] At present, UAV formation control systems are mainly divided into two categories: centralized formation control and distributed formation control. The centralized formation control system has a formation control center on the ground or in the air. The formation control center obtains information about the formation status of all UAVs, generates guidance instructions for each UAV, and periodically communicates to each UAV in the formation through a communication link. The machine sends corresponding guidance commands. Unlike the centralized formation control system, the distributed formation control system does not have a control center, and each UAV can generate guidance instructions independently. [0003] For centralized formation co...
