摘　　要：介绍了一种水声信号采集存储系统,该采集存储系统水下将8路水声模拟信号进行同步A/D采样,然后复用成1路高速数字信号,通过一根光纤远距离传输到岸上的上位机,上位机可以实现数据的实时存储和波形显示功能。该水声同步采集系统通过光纤作为传输介质,传输距离远,抗干扰能力强;可用于港口、海上钻井平台和石油码头等设施的安全防范及信息采集。In this paper, it introduces a design of multi-channels underwater-sound synchronization acquisition and storage system, which can make A/D synchronization acquisition to multiplex 8 channels underwater-sound analog signals into 1 channel high speed digital signal, and then uses one optical fiber remotely transmit it to the upper machine to achieve the data real-time storage and display wave. The system uses fiber as the transmission medium, which has the features of long distance transmission and powerful anti-jam- ming performance; it can be used for the safety protection of facilities at harbor, offshore drilling platform and oil terminal, and for the information collection of underwater weapon testing.
