Multi-redundancy power distribution system for unmanned plane

Abstract

The invention discloses a multi-redundancy power distribution system for an unmanned plane. The system comprises a power supply system, a voltage acquisition system, a controller and a flight control system. The power supply system is connected with the voltage acquisition system and also the flight control system. The controller is connected with the power supply system. The power supply system is formed by three or more than three power supply circuits, wherein the first power supply circuit includes a first power supply input, a first MOS transistor switch unit and a first power supply output, the second power supply circuit includes a second power supply input, a second MOS transistor switch unit and a second power supply output, and the third power supply circuit includes a third power supply input, a third MOS transistor switch unit and a third power supply output. The voltage acquisition system includes a first voltage acquisition part, a second voltage acquisition part and a third voltage acquisition part. The multi-redundancy power distribution system is applied to multi-redundancy power supplies and power supply distribution for an unmanned plane flight control system, provides multiple paths of power supply to the flight control system, preferably supplies power in an intelligent manner, and prevents the unmanned plane flight control system from being malfunctioning due to power supply problems.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle flight power supply system, in particular, the invention relates to a multi-redundant power distribution system for unmanned aerial vehicles. Background technique [0002] During the flight of the UAV, the stability of the power supply system is the guarantee for the safe flight of the UAV. The power supply of the current UAV flight control system is mostly a single-channel power supply. Once a single-channel power supply fails, it is difficult to remedy it. It is easy to cause flight accidents. Single-channel power supply has low safety factor and poor stability. Once the power supply link is abnormal, it may lead to abnormal flight control. If evasive remedial measures cannot be taken quickly and timely, it will easily lead to UAV flight accidents. Therefore, power supply system failure is Potential threats during drone flight.
