Deep sea acoustic receiving subsurface buoy and signal acquisition method

Abstract

The invention belongs to the technical field of marine environment and acoustic observation instruments, and particularly relates to a deep sea acoustic receiving subsurface buoy which comprises a watertight electronic cabin and wet-end corollary equipment, the watertight electronic cabin is mounted on the wet-end corollary equipment; according to a corresponding acquisition time table, the wet-end corollary equipment synchronously acquires multichannel analog underwater acoustic signals and transmits the multichannel analog underwater acoustic signals to a dry-end watertight electronic cabin,and the watertight electronic cabin performs digital-to-analog conversion on analog underwater acoustic signals of each channel and records and stores the converted digital underwater acoustic signals of each channel; meanwhile, the wet-end corollary equipment further comprises ocean instrument equipment, and the ocean instrument equipment synchronously records ocean environment parameters according to the corresponding collection time table, transmits the ocean environment parameters to the dry-end watertight electronic cabin and records and stores the ocean environment parameters.

Description

technical field [0001] The invention belongs to the technical field of marine environment and acoustic observation instruments, and in particular relates to a deep-sea acoustic receiving submerged mark and a signal acquisition method. Background technique [0002] The ocean is an important field of strategic significance, and the deep sea is the current research hotspot of marine resources, marine development, marine environment and marine security. Acoustic waves are considered to be the only physical medium that can travel long distances in seawater, and due to their good propagation characteristics in deep seas, there is an urgent need for applied research on long-distance underwater acoustic communication and its related propagation mechanisms. As a unique ocean observation equipment, the submersible buoy is an important technical means for ocean research. [0003] Ocean submersible buoy, also known as underwater buoy, is one of the important equipment for marine enviro...
