Problems solved by technology

Due to mechanical failure or external interference, one or more UAVs may have communication failures during the formation flight, making some communication links in the current communication topology unusable, resulting in the UAVs being unable to continue to maintain formation formation. In severe cases, it may even lead to UAV collision accidents

Abstract

The invention provides a reconstruction method and system for unmanned-aerial-vehicle formation communication topology based on a minimum arborescence. The reconstruction method includes the steps that broadcast communication channels are monitored, and whether communication failure of an unmanned aerial vehicle in a formation appears or not is judged; when communication failure of the unmanned aerial vehicle appears, a formation communication diagram is modified according to the model of the communication failure; a minimum arborescence of the modified formation communication diagram is calculated, and according to the calculated result, the unmanned-aerial-vehicle formation communication topology is reconstructed. When the communication failure of the unmanned aerial vehicle appears, the formation communication diagram is modified according to the model of the communication failure, the minimum arborescence of the modified formation communication diagram is calculated to reconstruct the unmanned-aerial-vehicle formation communication topology, and it is achieved that after the communication failure is detected, the communication topology is rapidly reconstructed so that UAV collision accidents are avoided, and a formation pattern is recovered.

Description

technical field [0001] The present invention relates to the technical field of UAV communication, in particular to a method and system for UAV formation communication topology reconstruction based on a minimum tree diagram. Background technique [0002] In the cruise phase, all unmanned aerial vehicles (UAVs) use the initial optimal communication topology to maintain a certain formation formation and fly towards the target area. The communication links in this communication topology are only part of the set of all available communication links between UAVs, that is, some communication links are not used, which are called redundant communication links. Due to mechanical failure or external interference, one or more UAVs may have communication failures during the formation flight, making some communication links in the current communication topology unusable, resulting in the UAVs being unable to continue to maintain formation formation. In severe cases, it may even lead to U...
