Unmanned aerial vehicle charging system and method based on near field identification interaction and multi-coil compatibility

The invention provides an unmanned aerial vehicle charging system and method based on near field identification interaction and multi-coil compatibility, and is used for solving the problem that an existing wireless charging system cannot be compatible with various types of receiving coils. The method comprises the steps that S1, an upper computer sends an enable signal to a transmitting end control panel, whether the transmitting end control panel can receive the enable signal at the moment is judged, if not, waiting continues, and if yes, the step S2 is executed; s2, identity recognition is carried out between the transmitting end and the receiving end of the system, if recognition cannot be carried out, the step S1 is carried out, and if recognition can be carried out, the step S3 is carried out; s3, the primary side starts to work with the constant phase shift value, whether the output voltage meets the requirement or not is detected, if yes, the step S1 is executed, and if not, the step S4 is executed; a
