Unmanned aerial vehicle intelligent power supply and distribution system

Abstract

An unmanned aerial vehicle intelligent power supply and distribution system is provided by the invention, and comprises an alternating-current generator, a power supply device, a storage battery, a power distribution center, a secondary power supply device, a power supply system processor, a solid-state power controller and a CAN bus. Aiming at the problems of poor power supply quality, no redundancy, no monitoring system and poor expansibility of the existing unmanned aerial vehicle electrical system, the system solves the problem of poor power supply quality of the unmanned aerial vehicle, fully utilizes the backup relationship between power supplies and a storage battery, provides redundant power supply, and monitors the working state of the system by using a real-time monitoring system, so the unmanned aerial vehicle is prevented from working abnormally due to the power supply problem in the flight process, In different mission profiles, different matching types are selected, and the expansibility performance is good.

Description

technical field [0001] The invention relates to an intelligent power supply and distribution system for an unmanned aerial vehicle, which belongs to the technical field of intelligent unmanned aerial vehicles. Background technique [0002] During the flight of UAVs, the high power quality of the power supply system, the real-time performance of the monitoring system, and good redundancy are important guarantees for the safe flight of UAVs. Most of the current UAV systems are powered by simple rectifier bridges. The direct output circuit has low power quality; most of them are single-channel power supply, once a fault occurs, it is difficult to remedy it, and it is easy to cause flight accidents; there is no monitoring system, and the power system parameters cannot be transmitted back to the ground in real time, so it is difficult for ground operators The real-time status of the UAV is used for emergency operations, and the flight safety of the UAV is greatly reduced. When m...
