Inductive power transmission and wireless local area network (WLAN) signal transmission-based underground equipment interface

The utility model discloses an inductive power transmission and wireless local area network (WLAN) signal transmission-based underground equipment interface, which comprises a socket and a plug. The socket and the plug are independently packaged, and are not directly connected electrically after being jointed, so that power and signals can be transmitted in a non-contact way. Non-contact underwater power transmission and non-contact underwater signal transmission are combined. Power can be unidirectionally transmitted from a base station to equipment by using an electromagnetic induction principle; and a WLAN signal can be bidirectionally transmitted between the base station and the equipment by using a wireless fidelity (WIFI) technology. Compared with the conventional wet plug connector adopting direct conductor contact, the underground equipment interface has the advantages that the direct conductor contact and complex sealing measures are not required, the conditions of water leakage and electric leakage are well avoided, and the long-term, continuous and stable running of underground electromechanical equipment and normal information interaction between the underground electromechanical equipment and an underground base station are well ensured.
