[0016] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0017] See also Figure 1 , Figure 1 A schematic diagram of a process flow of a wireless charging method for a drone in the stratosphere provided in an embodiment of the present application, wherein the method is used as follows: Figure 2 The drone wireless charging system 200 shown in FIG. Figure 2 As shown, the drone wireless charging system 200 includes a space power station and a drone, wherein the space power station includes a space power station power supply and a space power station output end, wherein the space power station is located in a geosynchronous orbit and remains relatively stationary with respect to the earth, and the space power station output end is used to convert the electric energy of the space power station power supply into laser, and use the laser to charge the drone, such as Figure 1 As shown, the stratospheric wireless charging method for unmanned aerial vehicles provided in the embodiment of the present application includes the following steps S1 to S2: Step S1, obtaining the location information of the drone, and judging whether the drone is flying at a preset height of the charging area of ​​the space power station based on the location information; specifically, the positioning module on the drone obtains the location information of the drone, and sends the location information to the first central processor at the output end of the space power station through the communication module, and after receiving the location information, the first central processor judges whether the drone is flying at a preset height of the charging area of ​​the space power station based on the location information; it should be noted that when the drone flies at the preset height of the charging area of ​​the space power station, it means that the drone is flying in the stratosphere of the charging area of ​​the space power station. It can be understood that, since the stratosphere has the characteristics of thin air, stable weather and good communication environment, on the one hand, the drone can perform tasks for a long time in the stratosphere, and on the other hand, when the drone flies in the stratosphere, it can use the efficient energy supply of the space power station to realize wireless charging of the drone, ensuring the stable operation of the drone in the stratosphere, and the space power station uses photovoltaic power generation method to convert solar energy into electrical energy.

[0018] Step S2: If yes, based on a preset laser emission method, the laser is emitted to the UAV through the output end of the space power station, and the UAV converts the laser into electrical energy when receiving the laser emitted by the output end of the space power station. Figure 2 As shown, the output end of the space power station includes a laser emitting device and a first alignment device, the laser emitting device is connected to the first alignment device, the first alignment device includes a first central processing unit and a first pan-tilt, the first central processing unit is electrically connected to the first pan-tilt, the laser emitting device includes a power laser generator, a power laser directional transmitter, a signal laser generator and a signal laser directional transmitter, the power laser generator is connected to the power laser directional transmitter, the signal laser generator is connected to the signal laser directional transmitter, the power laser generator and the signal laser generator are used to convert the electrical energy of the power supply of the space power station into laser, the signal The laser directional transmitter and the power laser directional transmitter are both arranged at the designated position of the first gimbal. The UAV comprises a laser power generation board, a second alignment device, a positioning module and a communication module. The positioning module is used to obtain the position information of the UAV. The communication module is used to establish a communication connection with the space power station. The second alignment device comprises a second central processor, a second gimbal and a photosensitive tube. The second central processor is electrically connected to the second gimbal and the photosensitive tube respectively. The laser power generation board and the photosensitive tube are both arranged at the designated position of the second gimbal. The laser emission method based on the preset laser emission method emits a laser to the UAV through the output end of the space power station, including the following steps: The positioning module obtains the location information of the drone and transmits the location information to the first central processor through the communication module; The first central processor generates rotation parameter information based on the position information; the rotation parameter information includes a rotation angle and a rotation direction; After the first central processor controls the first pan / tilt to rotate by the rotation angle along the rotation direction, the signal laser directional transmitter emits laser light; it should be noted that at this time, the laser light emitted by the signal laser directional transmitter will be directed toward the photosensitive tube; After the photosensitive tube receives the laser emitted by the signal laser directional transmitter, the second central processor controls the second pan / tilt to rotate so that the laser emitted by the signal laser directional transmitter is directed to the center position of the photosensitive tube; When the laser directional transmitter emits a laser toward the center of the photosensitive tube, the second central processor controls the second gimbal to rotate in real time so that the laser directional transmitter emits a laser toward the center of the photosensitive tube until the UAV leaves the charging area of ​​the space power station. In the process of the second central processor controlling the second gimbal to rotate in real time so that the laser directional transmitter emits a laser toward the center of the photosensitive tube, the power laser directional transmitter emits a laser toward the laser power generation board. Specifically, when the second central processor detects that the laser directional transmitter emits a laser toward the photosensitive tube, the power laser directional transmitter emits a laser toward the laser power generation board. When the center position of the sensitive tube is reached, an instruction to emit laser is sent to the power laser directional transmitter through the communication module, so that the power laser directional transmitter emits laser to the laser power generation board. After receiving the laser emitted by the power laser directional transmitter, the laser power generation board converts the laser into electrical energy, and transmits the electrical energy to the power supply voltage stabilizing module of the UAV. The third central processor of the UAV controls the power distribution module to distribute electrical energy based on the PID control method. The power device of the UAV provides power for the UAV during flight under the control of the third central controller, and the power device includes an electronic speed regulator, a motor and a propeller.

[0019] It should be noted that, due to the large transmission power of the power laser directional transmitter, if the power laser directional transmitter emits laser without aligning with the laser power generation board, it may cause irreversible damage to the drone. In this embodiment, when the laser emitted by the signal laser directional transmitter is directed to the center position of the photosensitive tube, the emission direction of the power laser directional transmitter is aligned with the laser power generation board. The power laser directional transmitter emits laser to the laser power generation board at this time, which can prevent the power laser directional transmitter from emitting laser without aligning with the laser power generation board and causing irreversible damage to the drone. It can be understood that, since the center position of the photosensitive tube will change during the movement of the drone, the method provided in this embodiment is to ensure that the power laser directional transmitter is aligned with the laser power generation board during the movement of the drone, and ensure the charging safety of the drone during the movement.

[0020] The method provided in this embodiment enables the space power station to provide power to the drone during its flight in the stratosphere, avoiding the situation where the drone needs to be recharged and return to the ground to interrupt its flight operation. By replenishing power in real time during the flight of the drone, the drone's flight time is extended, enabling it to perform long-term, high-intensity tasks, significantly improving the drone's operating efficiency and application scope.

[0021] In some embodiments, a plurality of the space power stations are provided in the geosynchronous orbit to achieve continuous endurance of the UAV during flight.

[0022] The method provided in this embodiment enables the drone to obtain electrical energy from each of the space power stations in a game of passing the parcel while flying in the stratosphere, thereby achieving wireless charging at any location and at any time in the world, and ensuring the continuous flight endurance of the drone.

[0023] like Figure 2 As shown, in some embodiments, the drone also includes a backup power supply.

[0024] In this embodiment, a backup power supply is provided for the drone to prevent the occurrence of insufficient power supply due to the space power station being unable to charge the drone during takeoff or descent due to obstruction of tropospheric clouds.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
