Multistage cascaded self-balancing mooring unmanned aerial vehicle system

Abstract

The invention provides a multistage cascaded self-balancing mooring unmanned aerial vehicle system. The whole system is composed of a plurality of mooring unmanned aerial vehicles; each unmanned aerial vehicle is provided with an upper interface module and a lower standard cable module; a serially configured mooring unmanned aerial vehicle set is formed by connecting the lower standard cable module of one of the plurality of mooring unmanned aerial vehicles with the upper interface module of another adjacent unmanned aerial vehicle; so the unmanned aerial vehicles are greatly improved in core technical indexes like load, stability, reliability and lift-off height.

Description

technical field [0001] The application of the present invention relates to an unmanned aerial vehicle, specifically a multi-stage cascade self-balancing moored unmanned aerial vehicle system. Background technique [0002] The tethered UAV system consists of a multi-rotor UAV, a tethered cable, and a ground take-off and landing platform. The UAV uses ground power to hover in the air for a long time. The built-in optical fiber of the cable is backhauled to the ground, which has the advantages of long-time operation in the air and large data transmission bandwidth. The whole system can be installed independently or on a vehicle, and can automatically and synchronously follow the movement of the vehicle. It is suitable for live TV, signal transmission, video surveillance and other fields. At present, "tethered UAV" mainly uses multi-rotor UAV or coaxial UAV as the body, generates lift through the rotor, and supplies power to the rotor motor through the tether cable, thus formin...

AI Technical Summary

Problems solved by technology

The limitations of the common "lift-off platforms" at present: fixed-wing aircraft, vertical rotor aircraft (helicopters), airships and other platforms need to carry their own energy, so the time to stay in the air is limited, and the cost is high; platforms such as tethered balloons are bulky , slow lifting, and low load; ordinary UAV platforms, limited by their own battery capacity, have limited load and battery life

[0004] At present, all tethered UAVs adopt stand-alone mode (that is, there is only one UAV in the whole system), so there are limit values ​​in core technical indicators such as load, stability, reliability, and lift-off height, and because only Improving the overall performance of tethered UAVs by improving the performance of core components (such as motors) makes it very difficult to improve the overall performance; in addition, currently all tethered UAVs use a single flight control module for unmanned Attitude control of drones has defects such as high technical requirements, poor wind resistance, large power loss, high cost, slow take-off, and low power utilization; There are bottlenecks in indicators (launch height, stability, reliability, load, etc.), which limit the development of the entire tethered drone industry
