A real-time power supply and high-speed data transmission submersible device based on submarine observation network

Abstract

The invention discloses a real-time power supply and high-speed data transmission submersible device based on a seabed observation network. The submersible device includes a seabed foundation deployed on the seabed and a vertical mooring system connected to the bottom surface of the seabed foundation and extending to the sea surface; The bed base acts as a gravity anchor to stabilize the submersible buoy device at the deployment site. It is also used to obtain the power supply of the submersible brigade device from the junction box of the submarine observation network, and sends the control commands sent by the junction box to the vertical mooring system, and the vertical The data collected by the mooring system is transmitted to the connection box in real time; the vertical mooring system adopts the structure of the integral load-bearing rope combined with the segmented main cable, and transmits the electric energy obtained from the seabed foundation to the sensors arranged on the load-bearing rope. The control commands from the seabed base send the sensor data of different set water depths to the seabed base. The invention changes the mode that the sensor of the traditional submersible mark relies on its own battery for power supply so that long-term high-speed acquisition cannot be achieved, and realizes long-term high-resolution observation of ocean water parameters.

Description

technical field [0001] The invention relates to the technical field of ocean observation, in particular to a submarine buoy device for real-time power supply and high-speed data transmission based on a seabed observation network. Background technique [0002] Marine science is a science based on observation. Marine scientific information is distributed on the water surface, water body and underwater; among them, information on the water surface (including the surface layer of the water body) can be obtained through satellite remote sensing and buoys, and underwater information can be obtained through seabed-based methods, including The water body observation with the most abundant marine information is generally realized through the vertical mooring submersible buoy system, and the data is obtained by deploying observation equipment at different depths, which has the advantages of wide range of observation depth, long observation time, relatively stable observation data, and ...

AI Technical Summary

Problems solved by technology

In this scheme, the power supply of each observation equipment can only rely on its own battery, which still cannot effectively solve the problem of real-time power supply. Due to energy constraints, all kinds of observation equipment carried by it cannot carry out long-term continuous sampling at a high sampling rate; in addition, the inductive coupling method Limited bandwidth and low transmission efficiency

[0006] Both of the above-mentioned submersible buoys have the disadvantages of limited power supply and the inability to take long-term intensive sampling, resulting in the inability to observe rapid phenomena such as ocean turbulence and internal waves; while the submarine observation network uses optical cables to build high-power power supply and high-speed communication networks. The connection port of the box realizes long-term stable power supply and high-bandwidth communication for underwater observation equipment, making it possible to invent a real-time power supply and high-speed data transmission submersible based on the submarine observation network

[0007] Patent application 201910928527.3 discloses a real-time submersible buoy transmission system based on the submarine observation network. This system only solves the technical problem of how to accurately connect the submersible buoy system with the submarine observation network, and does not introduce how to power and communicate with the observation equipment.
