Distributed Multi-Channel Underwater Acoustic Signal Acquisition System Based on LabVIEW
In order to meet the requirement of multi-channel underwater acoustic signal acquisition in underwater test field,a distributed multi-channel underwater acoustic signal acquisition system based on LabVIEW is studied.The system is controlled by the upper computer,sends commands and receives data through the Gigabit network,has 336 acquisition channels,sampling accuracy is 24 bits,and the maximum sampling rate is 204.8 kHz.The experimental results show that the system has the advantages of low noise,accurate sampling,stable operation and strong expansion,and can meet the requirements of multi-channel underwater acoustic signal acquisition.
