[0002] In the field of deep-sea exploration, HOV / ROVs such as Jiaolong, Discovery, and Haima are often used for deep-sea exploration operations. As underwater platforms, they can cooperate with single or multiple detection cabins to complete marine scientific research tasks; these detection cabins are often R & D and design by different units, the interface types are different, the common ones are BHF13, BHF6, Button, etc., the power supply voltage is also different, the common ones are DC 24V, DC 48V, AC 110V to 220V, the definition of each lead wire, network There are differences in communication methods. If the same set of detection cabin equipment is to be connected to different HOVs / ROVs, it is usually realized by customizing different adapter cables and rectifying the internal power supply and communication circuits of the detection cabin. The scheme of adding multiple interfaces suitable for different detection cabins or carrying platforms is expensive to maintain and upgrade, poor in operability and flexibility, and low in reality

[0003] With the rapid growth of deep-sea exploration demand, more and more detection cabins are equipped with HOV / ROV platforms, and the demand for joint work of multiple detection cabins is also increasing. The interfaces of each HOV / ROV are not uniform, the definition of leads is inconsistent, and the power supply voltage is different. The same and different communication methods have an increasing impact on the development of deeper scientific research work; due to the special underwater environment, the transmission distance of underwater network communication is generally low, which limits the actual working range of the detection cabin underwater

[0004] Based on the above reasons, it is necessary to find a solution with low cost, strong operability and flexibility to solve the problem that the same detection cabin is difficult to dock with multiple HOV / ROV underwater platforms with different interfaces and underwater network communication. The problem of short transmission distance
