Free telescopic ocean profile observation device and method based on large buoys

Abstract

The invention relates to a free telescopic ocean profile observation device and a method based on large buoys. The free telescopic ocean profile observation device comprises a free telescopic device,an underwater observation module, a data acquisition control module, a power supply module, a communication module and a data receiving and processing module, wherein the free telescopic device is used for providing power for underwater profile observation and accurate positioning of each depth layer; the underwater observation module is used for realizing integration and carrying of various observation sensors to acquire water body profile data; the data acquisition control module is use for intelligently controlling the action of the free telescopic device and the data acquisition of the underwater observation module according to sea conditions and forwarding the data to the communication module; and the communication module communicates with the data receiving and processing module of aland base station. By freely and accurately controlling the layer depth position of the underwater observation module, the free telescopic ocean profile observation device provided by the invention realizes long-term, continuous, fixed-point and real-time observation of the marine water body profile environmental parameters in a certain range under the condition of unattended operation, and breaks the current situation that the existing real-time observation parameters are limited to the surface layer of the sea.

Description

technical field [0001] The invention relates to the field of ocean observation, in particular to a freely retractable ocean multi-parameter profile observation device and method based on a large buoy. Background technique [0002] Ocean science is an observation-based science. At present, with the rapid development of observation technology, the ocean data acquisition method on which the development of marine science relies is changing from "investigation" to "observation". Realize all-round and all-weather three-dimensional monitoring of the marine environment, making the unexplored ocean a "transparent" world. However, most of my country's marine environmental observations still rely on ship-based observations and station fixed-point observations to periodically collect elemental data on the ocean surface or limited water layers. There is a lack of long-term continuous monitoring of ocean subsurface and deep water bodies. This is mainly due to the lack of effective techni...

However, most of my country's marine environmental observations still rely on ship-based observations and station fixed-point observations to periodically collect elemental data on the ocean surface or limited water layers. There is a lack of long-term continuous monitoring of ocean subsurface and deep water bodies. This is mainly due to the lack of effective technical means for implementing continuous profile observation

With the improvement of people's demand for marine science cognition, it is difficult to gain an in-depth understanding of the physical, biological, and chemical environments of my country's vast sea areas by only relying on ships to periodically obtain observation data of the ocean surface or limited water layers. , cannot meet the requirements of the development of modern marine science for all-round three-dimensional monitoring, let alone meet the needs of the development of my country's marine economy

[0003] Although my country has made great progress in offshore observation and underwater observation system technology, most of them rely on ocean wave energy to provide power or glider technology, which has poor stability; Real-time transmission back to the shore station; and because the current situation of random fishing in my country's coastal waters is still relatively common, fishermen's awareness of the protection of marine observation equipment is weak, resulting in frequent occurrences of various types of marine equipment being hit by fishing boats or dragged by fishing nets, seriously affecting the Continuous and effective acquisition of observation data
