In some embodiments, the metal plates of the first emitter plate group 11 are made of aluminum foil or copper foil materials, so that the weight of each emitter plate in the first emitter plate group 11 can be reduced and the volume of each emitter plate in the first emitter plate group 11 can be reduced. As another embodiment, each emission polar plate of the second emission polar plate group is a metal polar plate with an opposite polar plate surface being coated with an insulating layer or covering an insulating plate, and similarly, the insulating layer with a waterproof effect can be adopted for the insulating layer with the opposite polar plate surface being coated with the insulating layer, so that the waterproof effect on each emission polar plate can be achieved, and the waterproof effect on the metal polar plate and the effect of carrying the weight of the unmanned aerial vehicle 4 after the unmanned aerial vehicle 4 falls down can be achieved by each emission polar plate with the opposite polar plate surface covering the insulating plate.

In this embodiment, the packet control circuit 3 is implemented by 4 switch controls, as shown in fig. 4, when the first controller determines that the first emitter board 111 and the second emitter board 112 are required to be assembled 12, the first switch 31 is closed, the second switch 32 is opened, and the third switch 33 is opened and the fourth switch 34 is closed, as shown in fig. 4, at the landing position of the unmanned aerial vehicle 4. In other embodiments, the first controller controls the first switch 31 to open, the second switch 32 to close, and the third switch 33 to close and the fourth switch 34 to open when it determines that the first emitter plate 111 and the fourth emitter plate 114 are required to form the first emitter plate 111, and the second emitter plate 112 and the third emitter plate 113 are required to form the second emitter plate 112.

Therefore, by applying the coupling charging device provided by the embodiment, each transmitting pole plate can be freely assembled, and the offset tolerance capacity of the unmanned aerial vehicle 4 is improved.
As an embodiment, the device further includes a second controller, when the first controller determines that the power supply residual capacity of the unmanned aerial vehicle 4 is lower than a first threshold value, the first controller controls the unmanned aerial vehicle 4 to fly to a position where a ground charging station is located, and when the first controller is at a preset distance from the ground charging station, charging information indicating that charging is required is sent to the second controller; the second controller receives the charging information sent by the first controller, and starts an excitation source of the charging station so that the excitation source is in an excitation state; when the first controller determines that the power supply residual capacity of the unmanned aerial vehicle 4 is a second threshold value, power-off information for indicating stopping charging is sent to the second controller; and when the second controller receives the developed outage information of the second controller, the excitation source of the charging station is closed, so that the excitation source is in a stop excitation state.
The first controller and the second controller in this embodiment may be the same controller, or may be different controllers, which is not limited in this embodiment.
