Standby power supply system for mooring multi-rotor unmanned aerial vehicle

Abstract

The invention discloses a standby power supply system of a mooring multi-rotor unmanned aerial vehicle, which adopts a series super capacitor bank as an energy storage device, effectively solves the problem of low-temperature environment adaptability of a standby power supply of the mooring multi-rotor unmanned aerial vehicle, and widens the application scene of the mooring multi-rotor unmanned aerial vehicle. The remote controller can intervene in control under the abnormal condition in the standby power self-landing process of the multi-rotor unmanned aerial vehicle, so that the safety of the platform and the load is ensured; the main control unit monitors the operation state of the series super capacitor bank in real time, and voltage balancing is performed on the super capacitors through the balancing unit, so that the voltage balancing problem of the super capacitors in the series super capacitor bank is effectively solved, the influence of individual difference on the performance and the service life of the standby power supply is avoided, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a backup power supply system for a tethered multi-rotor drone. Background technique [0002] The tethered multi-rotor UAV is a new type of UAV system that combines a multi-rotor UAV and a tethered integrated cable. The essential difference between it and ordinary multi-rotor drones is that the power supply mode is changed from the onboard lithium battery to the direct power supply on the ground. Because it solves the endurance problem of ordinary multi-rotor UAVs, tethered multi-rotor UAVs are considered to be a major trend in the development of UAVs in the future. [0003] The tethered multi-rotor UAV system requires communication and control capabilities for a certain period of time after the external power supply is interrupted, so that the multi-rotor UAV can automatically descend with backup power and control it by remote control in abnormal situations to ensure the ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the conventional lithium battery backup power supply of the tethered multi-rotor UAV system is difficult to meet the operating temperature environment of the system, and when the heating treatment solves the low-temperature charging and discharging problem, the complexity and maintenance cost of the system will be increased. The purpose of the invention is to provide a backup power supply system for tethered multi-rotor drones to solve the above technical problems
