鲸豚声信号实时采集与分析系统

A System of Whale Sound Signal Acquisition and Analysis in Real-Time

本文设计了一套基于FPGA的鲸豚声信号实时数据采集与分析系统,在采集存储水族馆内声信号的同时,应用改进的HHT算法处理鲸豚叫声中的click信号,实现实时的甄别瓶鼻海豚和白鲸功能,可用于针对大型哺乳动物的远洋实时跟踪科考。

The real-time acoustic signal acquisition and discrimination technology of marine mammals(such as cetaceans and dolphins)is of great significance for ocean scientific research and marine ecological protection in China′s coastal waters.In this paper,a real-time data acquisition and analysis system of whale and dolphin sound signal based on FPGA is designed.The hardware of the system takes FPGA as the core.While collecting and storing the sound signal in the aquarium,the improved HHT algorithm is applied to process the click signal of whale and dolphin calls to realize the real-time identification of bottlenose dolphins and beluga whales,which can be used for real-time Ocean Tracking scientific research of large mammals.
