Power supply and distribution control device for unmanned aerial vehicle

Abstract

The invention discloses a power supply and distribution control device for an unmanned aerial vehicle. The power supply and distribution control device can reliably supply electricity and can achieve high efficiency, intelligentization, universalization and miniaturization. The power supply and distribution control device comprises a power supply control module, an airborne generator, a standby battery pack and a ground DC stabilized power supply, wherein the airborne generator is configured to supply electric energy to airborne electronic equipment of the unmanned aerial vehicle when the rotating speed of an engine is greater than an appointed threshold and to charge the standby battery pack which is not fully charged; the standby battery pack is configured to provide electric energy to the airborne electronic equipment of the unmanned aerial vehicle when the rotating speed of the engine is smaller than the appointed threshold or the engine is broken down; the ground DC stabilized power supply is configured to supply electricity when ground debugging is carried out and to charge the standby battery pack which is not fully charged; and the power supply control module is configured to be switched among three power supplies of the airborne generator, the standby battery pack and the ground DC stabilized power supply and to carry out serial port communication.

Description

technical field [0001] The invention relates to a power supply device on an unmanned aerial vehicle, in particular to a power supply and distribution control device for an unmanned aerial vehicle, which is mainly used for the power supply and distribution control of various airborne electronic equipment on the unmanned aerial vehicle. Background technique [0002] Power supply and distribution technology is the most important research content of the airborne electrical system. It is of great significance to have a high-efficiency power supply and distribution system to improve the overall performance of the drone. [0003] However, at present, most drones still use a single lithium polymer battery pack for power supply. Once the lithium polymer battery pack fails, it will lead to unimaginable consequences. In addition, due to the limited energy density, the battery pack occupies a large proportion of the weight of the entire flight platform, and the power supply efficiency ...

[0003] However, at present, most drones still use a single lithium polymer battery pack power supply scheme

Once the lithium polymer battery pack fails, it will lead to unimaginable consequences

In addition, due to the limited energy density, the battery pack occupies a large proportion of the weight of the entire flight platform, and the power supply efficiency is relatively low, and the power supply time is limited by the capacity of the battery pack, and the battery life is short

[0004] In recent years, power supply for the whole drone through the onboard generator power supply system has been widely and deeply carried out abroad; and many domestic companies have also carried out research and development work in this area, but in terms of high reliability, intelligence, Generalization and other aspects are lacking
