Research on information interaction design of underwater multi-platform of deep-sea vehicle based on acoustic optic and electromagnetic transmission technology

Abstract

Deep-sea underwater connection and information interaction technology, including core technologies such as electromechanical hydraulic interface connection and underwater signal interactive transmission, is an effective technical means to solve the problem of information interaction and collaborative operation between underwater multi-platform and sensor nodes. With a large number of deep-sea vehicles in service in China, the energy, signal, data and other interfaces of the vehicles have not been unified, which leads to the difficulty in realizing multi-platform collaborative operations, so it is urgent to carry out corresponding research. In this paper, based on the analysis of the current situation of the information interaction technology of Jiaolong manned submersible, we carried out the research and summary of the multi-platform information technology of the deep-sea vehicle, and focused on the requirements of the exploration of the complex terrain and the detection of the morphology of accumulation body in the deep-sea hydrothermal region, proposed the design idea of the underwater multi-platform information interaction based on acoustic optic and electromagnetic transmission technology with Jiaolong manned submersible as the carrier, and completed the scheme design of the information interaction system of acoustic, optic and electromagnetic, which will provide technical support for the realization of the cooperative operation and high-efficiency application of the deep-sea vehicle cooperative operation.
