Unmanned aerial vehicle cluster automatic flight crashproof apparatus and crashproof method

Abstract

he invention brings forward an unmanned aerial vehicle cluster automatic flight crashproof apparatus, and relates to the technical field of an unmanned aerial vehicle. The crashproof apparatus comprises multidirectional pulse detection devices which are arranged in three axial directions of an unmanned aerial vehicle, are disposed at the two ends of each axial direction, regularly send pulses to realize all-angle coverage in a space scope and calculates the distance between the unmanned aerial vehicle and other unmanned aerial vehicles; and a storage unit which is arranged inside the unmanned aerial vehicle and is used for storing body information of the unmanned aerial vehicle and received information of other unmanned aerial vehicles. According to the invention, real-time three-dimensional space collision detection is realized based on the multidirectional pulse detection devices, at the same time, according to preset pass authority, automatic flight under a conflicting environment between multiple vehicles is realized, and the apparatus substantially reduces the production cost and is easy to realize.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an anti-collision device and an anti-collision method for autonomous flight of a group of unmanned aerial vehicles. Background technique [0002] The existing UAV collision system focuses on avoiding static obstacles. For a cluster multi-machine automated flight environment, for a single machine, other flight units in the crew appear as dynamic obstacles. If there is no negotiation, only rely on The strategy of a single flight unit cannot effectively prevent collisions. [0003] In individual multi-aircraft flight schemes, complex visual recognition algorithms are required, the development complexity and product cost are high, and low-cost batch equipment cannot be realized. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention proposes an anti-collision device for autonomous flight of UAVs. The anti-collision de...
