Underwater wireless data transceiver based on inductive coupling

The utility model relates to an underwater wireless data transceiver based on inductive coupling. At present, the longer-distance unrepeated wireless communication of underwater data can not be implemented. A data transmitting terminal in the utility model is connected with a coupling signal transmitting module through a serial port; an output end of the coupling signal transmitting module is connected with a transmitting coil signal; a transmitting coil is arranged corresponding to a receiving coil; the transmitting coil is connected with the receiving coil in a seawater medium in an electromagnetic coupling manner; the receiving coil is in signal connection with an input end of a coupling signal receiving module; and the coupling signal receiving module is connected with a data receiving terminal through a serial port. The utility model can perform short-distance non-contact wireless transmission within the larger space angle range, has the advantages of low cost, low power consumption and the like, and is suitable for achieving the underwater short-distance non-contact wireless data transmission.
