AI Technical Summary

Problems solved by technology

At present, underwater signal transmission is mainly realized by underwater acoustic technology, but the processing of underwater acoustic signals is very complicated, and the power consumption of underwater acoustic equipment is also very large, which is not suitable for battery-powered scientific research tools.
Moreover, the deep-sea environment is special, and the use of a single communication medium cannot fully guarantee the success of the communication. The operation site needs a highly reliable redundant wireless signal transmission system

Abstract

The deep-sea non-contact signal bi-directional redundancy transport unit comprises science exploration tools, the computer on the bathyscaphe, the first and the second coils, the first and the second modem, the first and the second optic probe. The first and the second coils separate to each other and knot with axial cord, the distance of the front panels of the first and the second optic probe is within 5 meter. The first optic probe and the first coil are connected to the import / export port of the first modem, which are connected to the science exploration tools. The second optic probe and the second coil are connected to the import / export port of the second modem, which are connected to the computer.

Description

technical field [0001] The invention relates to a deep-sea non-contact signal bidirectional transmission device. Background technique [0002] Underwater autonomous robot (AUV), underwater remote control robot (ROV) and manned deep submersible vehicle (DSV) are the main carrying equipment for deep sea scientific investigation and resource exploration. During the diving operation, the above carrying equipment will be equipped with a series of scientific research tools. Two-way signal transmission is carried out between the scientific research tool and the computer installed in the submersible. In order to ensure the absolute safety of ROVs, AUVs and DSVs, the carrying equipment must be successfully separated from the scientific research tools in an emergency. Therefore, the communication between the carrier equipment and the scientific research tool needs to be realized by using a non-contact signal transmission device. At present, underwater signal transmission is mainly ...
