The invention discloses an underwater equipment interface based on inductive power transmission and wireless local area network (WLAN) signal transmission. The underwater equipment interface comprises a socket and a plug, wherein the socket and the plug are independently packaged, and are not in direct electrical connection with each other after being jointed, so that the non-contact transmission of electric power and signals can be realized. According to the underwater equipment interface, non-contact underwater power transmission and non-contact underwater signal transmission are combined, the electric power is unidirectionally transmitted from a base station to equipment by using an electromagnetic induction principle, and the WLAN signals are bidirectionally transmitted between the base station and the equipment by using a wireless fidelity (WIFI) technology. Compared with the conventional wet plug connector adopting the direct contact of conductors, the underwater equipment interface has the advantages that: the direct contact of the conductors and complex sealing measures are not required, the conditions of water leakage and electric leakage are well avoided, and the long-term continuous stable running of the underwater electromechanical equipment and normal information interaction between the underwater electromechanical equipment and the underwater base station are well ensured.
Description
technical field [0001] The invention relates to a general interface meeting the requirements of non-contact electric energy and signal transmission between an underwater base station and underwater electromechanical equipment. technical background [0002] The detection of marine environment and the development of marine resources have always been hot issues. The construction of submarine observation networks and the use of underwater electromechanical equipment have made the design and development of underwater devices flourish. For long-term stable operation of underwater electromechanical equipment, continuous underwater base stations are required. Power supply, and communication with the underwater base station. However, since water is a conductor of electricity, the power and signal transmission at the interface between the two devices should not be in direct contact with exposed conductors, such as wet plug connectors. Its high price and short life limit its wide appli...
