Embodiment Construction

[0059]The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0060] 1. Composition of drone clusters

[0061] UAV swarms can be divided into four levels: system layer, cluster layer, platform layer and unit layer.

[0062] Unit layer: A single piece of equipment that can independently complete simple task activities. Such as unmanned aerial vehicles, airborne artillery shells, additional reconnaissance equipment, ground control stations, etc.

[0063] Platform layer: Various UAV systems with different equipment and different capabilities for a common mission.

[0064] Cluster layer: According to the capabilities and characteristics of drones, a larger system composed of drone platforms that complete different tasks, according to a certain organizational relationship. For example, the reconnaissance UAV swarms by function, the decoy and jamming UAV swarms, the eastern UAV swarm and the central...

Abstract

The invention discloses an unmanned aerial vehicle cluster task reliability analysis method based on a cluster fault, and the method comprises the following steps: S1, searching a cluster fault from the aspects of a functional entity, information interaction, a use mode and a process, and determining a fault type needing to be considered at each level of an unmanned aerial vehicle cluster; S2, obtaining fault causes of cluster faults through fault criteria; s3, measuring the reliability of the unmanned aerial vehicle cluster according to the cluster fault, decomposing a cluster task into stage tasks, dividing a certain stage task of the cluster into a plurality of sub-stage tasks which are continuous in time and are not overlapped with one another, constructing a reliability model for each sub-stage task, calculating the reliability of the cluster task, and finding out reasons influencing the reliability of the task. According to the method, main reasons influencing the task reliability in stage tasks are found out, feedback is provided for unmanned aerial vehicle equipment system design and task planning, and the method is used for guiding selection of equipment entities, correction of performance parameters and adjustment of hierarchical structure relations.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, and more specifically relates to a method for analyzing the reliability of unmanned aerial vehicle cluster tasks based on cluster faults. Background technique [0002] UAV, also known as unmanned aerial vehicle, is an unmanned aerial vehicle system that integrates UAV aircraft, airborne sensors, airborne mission equipment, command and control system, communication system, measurement and control system, and comprehensive support system. The UAV swarm is composed of multiple UAVs with limited autonomous capabilities. Through the self-organization mechanism, without centralized command and control, they generate an overall effect through mutual communication and achieve a high degree of autonomous cooperation. Accomplish expected mission objectives with as little human intervention as possible. UAV swarms are not only widely used in the military, but also emerge in civilian fields...
