Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a vehicle-mounted tethered unmanned aerial vehicle system and an energy supply method thereof. Background technique [0002] In recent years, drones have been widely used in various fields. Whether it is commercial survey, scientific research or civilian life, there will be shadows of drones everywhere. However, for a long time, there are still some problems that have not been effectively solved in drones, which restricts the performance of many functions of drones, such as long-term and long-distance work such as battery life, flying loss, and "explosion" are difficult to carry out. . As a result, tethered drones came into being. [0003] The tethered UAV is a UAV system that combines the UAV and the photoelectric integrated cable. The tethered UAV transmits electrical energy through the photoelectric integrated cable, so that the UAV can stay in the air for a...

Problems solved by technology

Among them, the ship-borne mooring uses the ship as a mooring platform for the tethered UAV, and the tethered UAV can sail with the ship; the basic idea of ​​the fixed mooring is to arrange a certain number of charging piles on the ground, as long as There are charging piles during the flight, and the tethered drone can fly without interruption. You can add a charging platform to the existing street lamp to help the tethered drone’s battery life, or you can use the communication on the side of the road. Base stations, lampposts, and tops of buildings are used as docking stations for tethered drones. In places with imperfect infrastructure, utility poles can even be specially set up to deploy tethered drone docking stations based on the same principle. The condition for realization is that the layout of the charging piles must be densely distributed, but at present, the charging pile facilities cannot be realized on a large scale in the short term; the vehicle-mounted mooring uses mobile vehicles as the mooring platform, which has strong mobility and high flexibility. The vehicle-mounted power supply can stay in the air 24 hours a day, and the tethered UAV can also accurately follow the position of the free-moving base station vehicle, and perform high-frequency take-off and landing tasks. It is widely used in many aspects, especially it can play an important role in emergency emergencies, reducing the loss of manpower and material resources

[0005] However, the current vehicle-mounted moorings mostly use the "generator + DC high-voltage power supply" mode to supply power to UAVs. Most of them use the generator's own fuel in a mobile platform basic unit with a diesel generator. Keep the UAV in the air for more than 20 hours, but in practical applications, the demand is often far greater than this time. If you want to extend the time in the air, you need to refuel the generator, and the fuel that ordinary trucks can carry is limited; It connects to the mains and supplies power to the tethered UAV through the mains. However, because the tethered UAV travels in various places and may work in multiple places in a day, the operation of connecting to the mains is cumbersome. For remote mountainous areas, this method is still unfeasible
