Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, and the contents of the specific embodiments are not intended to limit the scope of protection of the present invention.

[0034] A multi-UAV security communication strategy that reduces unsafe areas, mainly including the following steps. The first stage: find the boundary node matrix edge;

[0035] 1.1 Initialize UAV group N, UAV communication radius r, and mark matrix mark.

[0036] 1.2 Calculate the adjacency matrix a_ij of multiple UAVs according to the adjacency relationship between UAVs. According to the formula ||q j -q i ||=d Calculate the distance between node i and node j, where q represents the position of the UAV, and N represents the set of UAV groups. If d<r, node i can communicate with node j, a_ij≠0, and vice versa. Where r is the communication radius of the UAV.

[0037] 1.3 Find the two points with the largest distance in ...

Abstract

The invention relates to a safe communication strategy of multi-unmanned aerial vehicle capable of reducing unsafe areas, which comprises the following steps: building a geometric model according to flight characteristics and cluster states of multiple unmanned aerial vehicles; designing a layering algorithm to layer the unmanned aerial vehicle cluster, and finding out a cluster boundary node; reducing the communication range of the boundary node, and finding out an optimal communication radius of the boundary node; designing a moving algorithm enabling the boundary node close to the cluster so as to finish effective communication; finally, proving theoretically that under the situation that the number of the nodes is infinite, the strategy can reduce the limit value of the proportion of unsafe areas. According to the strategy in the invention, the communication range of the boundary node of the unmanned aerial vehicle cluster is reduced to further reduce the range of the unsafe areas;the strategy has the advantages of simple operations and stable reduction of the range of the unsafe areas and the like. The multi-unmanned aerial vehicle cluster is enabled to communicate safely andeffectively. The multi-unmanned aerial vehicle collaborative operation in a battlefield environment has a wide application prospect.

Description

Technical field: [0001] The present invention relates to a method for multi-UAV safe communication, specifically a method suitable for multi-UAV cooperative flight, UAV communication range control and UAV flight position control to enable safe communication between UAVs The novel method belongs to the technical field of multi-UAV safe communication. Background technique: [0002] The so-called safe communication has nothing to do with the specific communication details, but refers to the research on making the group of UAVs relatively safe by controlling the communication range of UAVs and the flight position of UAVs. In the process of carrying out missions with multiple drones, if the communication radius of the drone is greater than the detection radius of the drone, there will be a blind spot for detection outside the detection range of the drone. In this area, the enemy aircraft can easily Obtaining the communication message of the UAV group without being detected by th...
