Research and Design on Water Sound Acquisition System of Deep Sea Ultrahigh Pressure Environment

Abstract

This paper is to introduce a water sound acquisition system for ultrahigh-pressure environ ment in the deep sea. The system is designed based on NI PXIe hardware platform, and LabVIEW is used for software development. The system has realized real-time detection of signals, frequency analysis, data preservation, alarming and recording for over-limit signals and data callback. Test results have shown that the system is stable in operation as well as reliable and accurate in data detection.
