An anchor mooring profile monitoring buoy based on underwater non-contact wireless communication

The anchor mooring profile monitoring buoy can obtain the long-term, fixed-point and high vertical resolution vertical profile monitoring data of the specific sea area. To guarantee the communication reliability and the safety of the profiler, an underwater non-contact wireless communication system based on electromagnetic induction coupling is presented in this paper. This system can realize the low cost, low power consumption, low directionality demand, reliable and short-distance data transmission between the underwater profiler and the floating body. The underwater experimental results show that the system can realize the reliable half-duplex non-contact wireless communication at 9600 bps when the distance and the axial direction between the two coupling coils are less than 20 cm and 60 degree respectively.
