Problems solved by technology

The acoustics of the marine environment is complex, and the noise of the marine environment is the sum of non-correlated anisotropic and isotropic energy density fields. The current conventional technology is to measure the overall scattering characteristics of the wake through an external acoustic sensor. This method cannot obtain the internal acoustic characteristics of the wake, and each This kind of measurement is based on the scalar sound pressure receiver, i.e. hydrophone, a...

Abstract

The invention discloses a suspended marine environment acoustic characteristic comprehensive measuring device with a receiving/transmitting function. The device comprises a solar panel, a floating body tank, a storage battery, a charger, a cable sliding watertight piece, a salinity sensor, a temperature sensor, a pressure sensor, an anchor block, an integrated cable, a vector hydrophone, a cable wheel, a speed reducer, a servo motor, a controller, a data processing module, a GPS module, a Beidou communication module, a GPS antenna and a Beidou communication antenna. One end of the integrated cable is connected with the data acquisition and processing module and enters seawater through the cable wheel and the cable sliding watertight piece, the anchor block is arranged at the tail end of the integrated cable, the vector hydrophone and the sensors are arranged on the integrated cable, data collected by the sensors are sent to the data acquisition and processing module through the integrated cable and then sent to the controller after being processed, and a solar power generation device charges the storage battery through the charger. According to the invention, the vector hydrophoneis taken as a core, so that the marine acoustic characteristic parameters can be measured comprehensively, accurately and for a long time in an energy self-supplementing manner.

Description

technical field [0001] The invention relates to a device for measuring the acoustic characteristics of the marine environment, in particular to a suspension type comprehensive measurement device for the acoustic characteristics of the marine environment with receiving / transmitting functions. Background technique [0002] The study of marine environmental acoustics plays an important role and significance for marine engineering construction and civil and military maritime safety. The acoustics of the marine environment is complex, and the noise of the marine environment is the sum of non-correlated anisotropic and isotropic energy density fields. The current conventional technology is to measure the overall scattering characteristics of the wake through an external acoustic sensor. This method cannot obtain the internal acoustic characteristics of the wake, and each This kind of measurement is based on the scalar sound pressure receiver, i.e. hydrophone, and cannot completely...
