All sea depth profile stereo buoy observation system based on photoelectric composite cable

Abstract

The invention discloses an all sea depth profile stereo buoy observation system based on a photoelectric composite cable. The observation system comprises a sea surface buoy platform, a buoy anchor system and a sea bottom observation system which are successively connected; the sea surface buoy platform is provided with a data acquisition system and a power supply system; the buoy anchor system comprises a photoelectric composite cable, and a plurality of branches are separated on the photoelectric composite cable through a plurality of separation boxes and carried out photoelectric separation, and each branch is used for hanging and mounting observation sensors; and a data acquisition unit collects data of the observation sensors on the photoelectric composite cable and in the sea bottomobservation system to realize observation of a profile and a sea bottom. The observation system adopts the separation boxes on the photoelectric composite cable for photoelectric separation, continuous power supply of the sensors is realized through a separated optical unit, and stable operation of the system is ensured.

Description

technical field [0001] The invention belongs to the technical field of ocean monitoring, in particular to a three-dimensional buoy observation system based on a photoelectric composite cable. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Ocean buoys are automatic observation stations for ocean hydrology, water quality and meteorology that are mainly composed of observation buoys anchored at sea. It can collect the required marine hydrology, water quality and meteorological data for marine scientific research, offshore oil (gas) development, port construction and national defense construction in a long-term and continuous manner in accordance with regulations, especially for the collection of severe weather and sea conditions that are difficult for survey ships to collect. material. With the development of ocean monitoring, the indicat...

AI Technical Summary

Problems solved by technology

[0005] The power supply of the underwater sensor is provided by its own battery, the capacity is limited, and it cannot work at high frequency for a long time;

[0006] The real-time communication method of underwater sensors is inductively coupled, and the data bandwidth is small, so it is impossible to transmit large amounts of data;

[0007] The submarine observation equipment adopts self-contained structure, which cannot realize real-time data transmission, so it is impossible to realize disaster forecast and early warning
