Early warning device for unmanned aerial vehicle and overhead alternating-current power line collision avoidance

Abstract

The invention claims an early warning device for unmanned aerial vehicle and overhead alternating-current power line collision avoidance. The early warning device includes an unmanned aerial vehicle on-board dynamic electric field measuring device, an unmanned aerial vehicle flight control module, a power source module, a power line presence judgment module, a power line approaching judgment module, and a dangerous zone judging and early warning module; the unmanned aerial vehicle-mounted dynamic electric field measuring device is internally provided with an electric field measuring sensor, asignal processing unit, a microprocessor and a signal transmission unit; the unmanned aerial vehicle flight control module is used for providing flight information for the electric field measuring device and receiving early warning information; the power source module is used for supplying power to a measurement and early warning system; the power line presence judgment module is used for judgingwhether a power line is present near an unmanned aerial vehicle; the power line approaching judgment module is used for judging whether the unmanned aerial vehicle is gradually approaching the power line; and the dangerous zone judging and warning module is used for performing graded evaluation on the risk of a distance between the unmanned aerial vehicle and the power line. According to the earlywarning device of the invention, on-board dynamic electric field measurement and real-time judgment are adopted, so that the unmanned aerial vehicle can intelligently, fast and accurately identify that the unmanned aerial vehicle is approaching an overhead alternating-current power line and issue early warning information.

Description

technical field [0001] The invention belongs to the application field of unmanned aerial vehicles, and in particular relates to an early warning device for avoiding collisions of unmanned aerial vehicles with overhead AC power lines. Background technique [0002] At present, small and medium-sized civilian drones are developing rapidly, especially multi-rotor drones, which have the advantages of small size, light weight, and simple operation. , monitoring infectious diseases, surveying and mapping and other professional fields have been widely used. At the same time, the consumer drone market is also expanding rapidly, and more and more ordinary people have begun to enter the world of drones. [0003] With the increase of UAV applications, the safety of UAV flight has become increasingly prominent. In recent years, there have been frequent reports of accidents caused by drones colliding with overhead power lines. In the lightest cases, the drones were damaged, and in sever...

Problems solved by technology

[0008] These requirements make its application too specific and not suitable for non-electric line inspection drones

Because it is impossible for UAVs used for aerial photography, aerial surveys, transportation, etc. to know the specific information of the nearby power lines in advance and the structural relationship between UAV flight routes and circuits during long-distance flight.
