UAV intelligent battery dropping control system

Abstract

A UAV intelligent battery dropping control system carries a plurality of batteries in parallel to successively supply power to a UAV one by one, wherein a battery interface is screwed to a power supply connection device through a slip ring; the batteries are attracted to a battery fixing frame by a battery attraction unit; a power measuring unit monitors the power of the batteries; an enable control unit performs short-circuit control on an electromagnetic attraction device, and then automatically drops the batteries and a power supply line connector; when a battery attitude detecting unit detects that the battery falling acceleration is greater than a set threshold by an attitude module, an parachute is opened so that the batteries slowly descend in virtue of the parachute; a positioningmodule transmits the GPS / BD data back to the ground through a transmitter, facilitating the recycle of the dropped batteries.

Description

technical field [0001] The invention belongs to a battery power measurement and battery drop control system for an unmanned aerial vehicle, and relates to an intelligent battery drop control system for an unmanned aerial vehicle. Background technique [0002] At present, the UAV market has already entered the stage of large-scale and industrial growth. UAVs are widely used in map surveying, electric power survey, agricultural plant protection, forestry fire prevention, marine monitoring, oil pipeline inspection and other fields, with a wide range of applications , There are many application channels. [0003] UAV is a systematic integrated platform, involving multiple professional fields, such as communication, control, structure, chemistry and so on. As a support, the platform supports many systems such as data transmission, data transmission, and control, and the energy source of the platform has a direct impact on the performance of the platform. [0004] At present, th...

Problems solved by technology

[0004] At present, there are two main energy sources for UAV platforms on the market. One is electric energy. At this stage, it is mainly lithium batteries, which are relatively small in size and short in flight time. At the current stage, most of the lithium battery platform UAVs The endurance time is within 1 hour; the second is fuel power, which can provide a longer flight time, but the control system of the device is not as accurate as the electric control system, and the maintenance is also more complicated than the electric system. When stable flight is required, the performance is not as good as the electric system.

Hydrogen fuel cells, which have emerged in recent years, have not been able to be popularized due to their comprehensive cost and safety issues
