1. An autonomous moving device wireless charging system, comprising an autonomous moving device and a wireless charging station, wherein:
the wireless charging station comprises a wireless charging transmitting end;
the autonomous moving device comprises a wireless charging receiving coil and a battery;
the wireless charging receiving coil is configured to receive a charging signal transmitted by the wireless charging transmitting end, the charging signal transmitting an electric energy and being used for generating an induced voltage or current in the wireless charging receiving coil to charge the battery;
the battery is electrically connected to the wireless charging receiving coil and is configured to receive the electric energy transmitted from the wireless charging receiving coil; and
the autonomous moving device is configured to:
determine, based on a detected intensity, at the wireless charging receiving coil, of the charging signal transmitted by the wireless charging transmitting end, satisfying a threshold, that the autonomous moving device is at a charging location; and
in response to determining that the autonomous moving device is at the charging location, dock at the charging location.
