Embodiment Construction

[0016] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0017] In one of the embodiments, the present invention proposes a method for avoiding unmanned aerial vehicle flight, the method comprising the following steps:

[0018] S1 pre-plans the overall flight path for each UAV, and enters the overall flight path into the flight control computer of the corresponding UAV;

[0019] S2 integrates the ADS-B module in each flight control computer. The ADS-B module broadcasts the flight information of the drone it carries in real time. The flight information includes the aircraft code, the current coordinate point and the preset time period from the current time point. the future flight path of

[0020] Any ADS-B module of S3 can receive the flight information sent by ADS-B modules on all other drones in the preset flight area, and compare the future flight path in the receive...

Abstract

The invention relates to a UAV flight avoidance method and system, wherein the method comprises: pre-planning an overall flight path for each UAV; integrating an ADS-B module into each flight controlcomputer, wherein the ADS-B module broadcasts the flight information of the UAV carrying the ADS-B module in real time, and the flight information includes an aircraft code, a current coordinate pointand a future flight path within a preset time period from a current time point; enabling any ADS-B module to receive the flight information sent by the ADS-B modules on all other UAVs in a preset flight area, compare the future flight paths in the received flight information with its own overall flight path, and calculate an avoidance path by using an avoidance algorithm if the comparison is successful in order that the corresponding UAV achieves avoidance flight according to the avoidance path. The method and system can realize the autonomous avoidance of multiple UAVs without a ground control center. When multiple UAV routes conflict, the method and system have obvious autonomous avoidance advantages.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and system for avoiding unmanned aerial vehicle flight. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. The important technical support to ensure the safety of UAV automatic driving is UAV flight avoidance technology. When the number of drones is large, autonomous avoidance of drones will be particularly important. At present, the existing UAV avoidance technology often relies on the ground control center. Once the multi-UAV communication fails, it will directly threaten the safety of UAV automatic driving. Contents of the invention [0003] Based on this, it is necessary to provide a UAV flight avoidance method and system for the problem that the current UAV avoidance technology often relies on the ground control center. [0004] In order to solve the a...
