Ocean environment noise measurement device based on wave glider

Abstract

The present invention discloses an ocean environment noise measurement device based on a wave glider. A wave glider is taken as a measuring platform to carry ocean environment parameters and noise measurement device so as to achieve fixed-point measurement and moving-type measurement. A collection control system is arranged on the wave glider, and comprises an embedded controller, a navigation device, a positioning device, a satellite communication device, a direction regulation device, a storage card, a synchronous interface, a measurement sensor, a power supply management circuit, a solar power system and a ZigBee module. Ocean environment parameters such as a wind speed, a wind direction, a wave height, a wave direction, rainfall, a flow rate and a flow direction are synchronously measured while measurement of the ocean environment noise, passing ship information is obtained through AIS to lay the foundation of analysis of influences of wind, wave, flow, rainfall and ships on measurement of ocean acoustic signals to facilitate deep research of a formation mechanism and a sound intensity fluctuation rule of the ocean environment noise so as to provide a reliable basis for improving the water sound communication stability and detection and identification capacity of the water sound detection device.

Description

technical field [0001] The invention relates to an ocean noise signal measuring device, in particular to an ocean noise signal measuring device based on a wave glider. Background technique [0002] Ocean environment noise is a kind of background interference field in underwater acoustic channel. The research on ocean environment noise is of great significance both in civil and military applications. On the one hand, artificial or natural noise as the inherent background sound field of underwater acoustic channels will directly affect the performance of various sonar equipment; on the other hand, marine environmental noise contains a large amount of hydrological, geological and marine biological information. By analyzing the noise of the marine environment, parameters related to the ocean can be estimated, such as sea surface wind speed, rainfall, waves, sea bottom reflection critical angle, sea bottom sound velocity and other parameters, providing conditions for further rese...
