Vehicle-mounted power supply management and control system and equipment for small-sized unmanned aerial vehicle

Abstract

The invention provides a vehicle-mounted power supply management and control system and equipment for a small-sized unmanned aerial vehicle. The system comprises a power supply switching and power supply management module, a power supply and distribution module, a data acquisition and interface conversion module; the power supply switching and power supply management module is used for realizing rectification and filtration, power supply switching, voltage conversion of a three-phase power supply of a generator and online charging of a backup battery group; the power supply and distribution module is used for realizing power supply and distribution for a self-driving vehicle, a steering engine, an electronic control unit, a short message device, a broadcasting station and an internal control circuit; and the data acquisition and interface conversion module is used for realizing voltage acquisition for the battery group, ECU data framing, electric level conversion from TTL to RS232 and control for a main power supply module and two electrical switching circuits. According to the vehicle-mounted power supply management and control system and equipment for the small-sized unmanned aerial vehicle, the integration degree of the avionics system of the unmanned aerial vehicle is higher; the power supply for the electric generator of the unmanned aerial vehicle is realized; and the flying endurance and the flying reliability are greatly improved.

Description

technical field [0001] The present invention relates to the field of aviation technology, in particular to a small unmanned aerial vehicle onboard power supply management and control system and equipment. Background technique [0002] At present, the power supply and distribution of small fixed-wing UAVs are basically powered by battery packs, which seriously restricts the flight time of the aircraft, and as the flight time increases, the battery packs on board will become heavier and heavier. This is not permissible, or even a serious flaw, for man-machines, and drones using small on-board generators solve this problem. [0003] But if a small on-board generator is used, how to control the on-board generator and the backup battery pack to realize the reasonable and normal operation of the power system and realize the long endurance of the UAV. Becoming a technician needs to consider issues. Contents of the invention [0004] The technical problem to be solved by the pre...
