Underwater space three-dimensional sound field detection system and method

Abstract

The invention discloses an underwater space three-dimensional sound field detection system and method. The detection system comprises a wet end electronic assembly and a dry end electronic assembly electrically connected with the wet end electronic assembly, and the dry end electronic assembly is sealed in a dry container; the wet-end electronic assembly comprises a horizontal sound field information acquisition device, a vertical sound field information acquisition device and a data transmitting device; the dry-end electronic component comprises a control storage module, and an analog-to-digital conversion module, an interface module and a power amplifier module which are electrically connected with the control storage module, wherein the interface module is in communication connection with the analog-to-digital conversion module and is used for receiving clock signals; the analog-to-digital conversion module is respectively in communication connection with the horizontal sound field information acquisition device and the vertical sound field information acquisition device; and the power amplifier module is in communication connection with the data transmitting device. According to the underwater space three-dimensional sound field detection system, the data acquisition range and the data acquisition capability of the underwater sound field detection system are effectively improved.

Description

technical field [0001] The invention relates to the technical field of marine acoustic environment monitoring, in particular to a system and method for detecting a three-dimensional sound field in an underwater space. Background technique [0002] The existing sonar mounted on unmanned boats has the following three problems: first, the sensor array has a single form, and it is impossible to obtain the three-dimensional sound field information of the marine environment, and the limitations of data collection directly affect the analysis results of subsequent data processing; second, the current The working mode of the sensor array is single, and each sensor cannot be individually controlled, collected and stored, and the synchronization between the sensor groups is poor, which will greatly limit the flexibility of the sonar equipment; finally, due to unmanned Due to the action of boat motion and water flow, the sensor array formation will be disturbed. If correct data compens...

[0002] The existing sonar mounted on unmanned boats has the following three problems: first, the sensor array has a single form and cannot obtain the three-dimensional sound field information of the marine environment, and the limitations of data collection directly affect the analysis results of subsequent data processing; second, the current The working mode of the sensor array is single, and each sensor cannot be individually controlled, collected and stored, and the synchronization between the sensor groups is poor, which will greatly limit the flexibility of the sonar equipment; finally, due to unmanned Due to the influence of boat motion and water flow, the sensor array formation will be disturbed. If correct data compensation is not performed, it may directly affect the accuracy of data collection.

This method has disadvantages such as long period, high cost, and prone to data loss.
