Seabed data monitoring device and system

Abstract

The invention provides a seabed data monitoring device which comprises a buoy device, a subsurface buoy device, a seabed monitoring box and cables, the buoy device, the subsurface buoy device and the seabed monitoring box are connected through the cables, and the cable between the subsurface buoy device and the seabed monitoring box is used for transmitting optical signals. The cable between the subsurface buoy device and the buoy device is used for transmitting electric signals, the seabed monitoring box transmits monitored seabed data to the subsurface buoy device in the form of optical signals, and then the subsurface buoy device converts the optical signals into the electric signals and transmits the electric signals to the buoy device in the form of the electric signals. The invention further provides a seabed data monitoring system. According to the invention, the submarine data monitoring efficiency can be improved, and the maintenance cost is reduced.

Description

technical field [0001] The present application relates to the technical field of marine data observation, in particular to a seabed data monitoring device and a seabed data monitoring system. Background technique [0002] In recent years, countries all over the world have accelerated the pace of research and development of deep-sea observation and seabed sensor technology, paying special attention to deep-sea technologies such as ocean detection, underwater acoustic communication, and seabed mineral resource exploration. Therefore, seabed fixed in-situ observation systems and underwater Seabed observation methods such as mooring stereo observation system. [0003] Buoy technology began to be used for deep-sea observation, which is mainly used to obtain full-section data of the upper ocean or shallow sea. Most of the existing buoys use the form of underwater steel cables to transmit seabed data. In this form, the steel cables are directly suspended at the bottom of the buoy ...

AI Technical Summary

Problems solved by technology

Most of the existing buoys use the form of underwater steel cables to transmit seabed data. In this form, the steel cables are directly suspended at the bottom of the buoy on the sea surface. Large and broken; and because the steel cable is also used for power supply and communication functions, the structural requirements for the cable system are extremely high

In addition, most traditional seabed observation systems store data in local memory, and need to read data at certain time intervals. The timeliness of seabed data monitoring is poor.
