The scheme based on the electromagnetic coupling module has the advantages of simple system structure, low failure rate and convenient for offshore operation.
Electromagnetic coupling uses the coupling of magnetic ring and plastic coated steel cable to realize the simultaneous transmission of data and energy by a single steel cable using seawater circuit.
Electromagnetic coupling is different from ordinary towed data measurement. Electromagnetic coupling uses plastic coated steel cables to transmit the data of deep-sea sensors to the deck in real time, which is convenient for users to respond in time according to the actual real-time data and improve the success rate and efficiency of measurement.
Electromagnetic coupling belongs to non-contact information transmission. Increase or decrease the number of sensor modules as required, replace and repair modules at any time, and reduce the impact of a single module on the whole.
Power transmission efficiency of electromagnetic coupler ≥70% data transfer rate not less than 1200Bps
