Technical Field

The disclosure relates to the technical field of electronics, in particular to a multi-battery power supply control method and device and an unmanned aerial vehicle.

Background

Unmanned aerial vehicles often fly away from the operator's field of view in flight, and if the misoperation, unmanned aerial vehicle may lose control and fall somewhere. For example, after the aircraft explodes, the whole system is powered off, and the unmanned aerial vehicle loses control; as another example, due to differences in the batteries of the drones, an airborne outage situation may occur, resulting in a loss of the drone. After the unmanned aerial vehicle loses power and flies to lose, all information can not be obtained, and the earth's surface environment is complicated, so that the difficulty of finding back by the unmanned aerial vehicle is increased.

Because the position when unmanned aerial vehicle is out of control often is inconsistent with the final position that falls to the ground, if the built-in positioner of unmanned aerial vehicle and communication device can not normally work, hardly acquire the exact position of unmanned aerial vehicle. One solution is to add a separate positioning communication device. Then, a general drone is equipped with a perfect positioning communication device, and the above independent positioning communication device can usually only operate for one day, which is a waste of hardware and increases cost.

For example, the unmanned aerial vehicle may include a first device group and a second device group, and two groups of battery packs are configured, that is, the first battery pack and the second battery pack, for example, the first battery pack is a main battery, the second battery pack is an auxiliary battery, and the first battery pack and the second battery pack may supply power to different (there may be overlap) devices, for example, the first battery pack may supply power to the first device group and the second device group, and the second battery pack may supply power to only the first device group. It should be understood that, in the embodiments of the present disclosure, the battery pack supplying power to the device group may refer to supplying power to one or more devices in the device group through one or more batteries in the battery pack.

Wherein the first device group comprises different devices than the second device group. For example, the first device group may include devices that consume less power, such as power consumption below a first threshold; the second device group may include devices that consume higher power, such as devices that consume power above a second threshold. The first threshold and the second threshold may be preset, and the second threshold is equal to or higher than the first threshold. As another example, the first device and the second device may be set when the drone leaves a factory, or set by a user in a customized manner, and so on. The embodiment of the present disclosure is not limited to the manner of dividing the first device group and the second device group.

The following describes the control method for multi-battery power supply in detail by taking the case that the control method for multi-battery power supply is applied to an unmanned aerial vehicle, and two groups of battery packs, namely a first battery pack and a second battery pack, are configured in the unmanned aerial vehicle, the first battery pack is a main battery, and the second battery pack is an auxiliary battery.

Optionally, it may also be determined that the unmanned aerial vehicle is in an uncontrolled state when an alarm indication sent by an electronic device associated with the unmanned aerial vehicle is received, and the like.

Further, the operating state of the first battery pack may include a normal operating state or an abnormal operating state. The normal operating condition can mean that first group battery is in "non-outage" state, through first group battery output electric energy promptly, for the state of unmanned aerial vehicle power supply. The abnormal working state may refer to a state that the first battery pack is in a power-off state, that is, the first battery pack cannot supply power to the unmanned aerial vehicle, that is, the first battery pack does not output electric energy.

102. If the first battery pack is in a normal working state, the first battery pack is used for at least supplying power for the warning device of the first equipment group of the unmanned aerial vehicle.

For example, when the main battery is in a normal working state, the main battery is controlled to supply power to (part of or all of) the unmanned aerial vehicle. When the main battery is in an abnormal working state, the control supplies power to the unmanned aerial vehicle (part or all equipment in the unmanned aerial vehicle) through a second battery pack, namely an auxiliary battery, and at the moment, the main battery is switched to the auxiliary battery to supply power to the unmanned aerial vehicle.

When the unmanned aerial vehicle is in an out-of-control state, such as after the unmanned aerial vehicle is lost, the control device can turn on the warning device to indicate the position of the unmanned aerial vehicle through the warning device. The warning device comprises a light alarm and/or a sound alarm, and the like, for example, the light alarm may comprise one or more LEDs, and the position of the drone may be indicated by turning on the one or more LEDs and controlling the one or more LEDs to flash; as another example, the audible alarm may include one or more speakers (e.g., speakers) so that the position of the drone can be indicated by activating the speakers, sounding, etc., to name but a few.

Because flight control device, power device, perception device etc. on the unmanned aerial vehicle have generally occupied the most of consumption, and be used for equipment such as location, communication only account for very little consumption proportion, consequently, can be when first group battery is main battery out of work (is in abnormal operating condition), supply power for this part equipment that the consumption proportion is less through second group battery auxiliary battery promptly to promote and seek the success rate, reduce and seek the cost.

Optionally, when the first battery pack is in a normal operating state, the first battery pack may charge the second battery pack, that is, the control device may control the second battery pack to be charged through the first battery pack. Further optionally, before the first battery pack charges the second battery pack, the control device may further obtain a remaining power of the second battery pack, and determine whether the remaining power is lower than a preset power threshold; and if the current battery capacity is lower than the preset electric quantity threshold value, executing the step that the first battery pack charges the second battery pack. The charge threshold may be preset, for example, 60%, 80%, and the like. That is, in this embodiment, the main battery can charge the auxiliary battery according to the electric quantity of the auxiliary battery, so as to ensure that the electric quantity is sufficient.

In the embodiment of the disclosure, a control device can detect the working state of a main battery in an unmanned aerial vehicle when the unmanned aerial vehicle is in an out-of-control state, and use the main battery to supply power to an alarm device of a first equipment group of the unmanned aerial vehicle when the main battery is in a normal working state; when the main battery is in abnormal operating condition, use auxiliary battery to do alarm device supplies power to the realization is switched to auxiliary battery and is supplied power when unmanned aerial vehicle's main battery can't normally work, helps flying to lose the back at unmanned aerial vehicle and realizes right unmanned aerial vehicle's seeking has promoted the probability that unmanned aerial vehicle was retrieved, and has reduced the cost of seeking.
