| 摘 要： | 设计了一种双通道数字水听器。采用FPGA对经过放大调理的数字水听信号进行采集,采用32位微处理器STM32F107和网络接口芯片DP83848实现以太网接口的设计方法,硬件少、易于实现和使用方便,适合现在的网络传输系统。通过试验,测得系统的传输速率达到了400Kb/s,满足了水听器及水听器基阵对传输速率的要求。数字水听器信号处理能力强,提取的信息更加准确、可靠,水听器处理的信号既可通过多种总线实时同水面的电子设备进行通讯,也可作为独立的测试系统,自身进行信息的处理和保存。

| Abstract: | A dual channel digital hydrophone was researched and designed.FPGA is used to col-lect digital and amplified hydrophone signal,32 bit microprocessor STM32F107 and network inter-face chip DP83848 is used to achieve Ethernet in-terface design,which has less hardware,is easy to implement and use,suitable for the current net-work transmission systems.Through experiment, system transmission rates by measured is up to 400Kb/s,satisfy requirement of the hydrophone and array of hydrophones.The digital hydrophone has strong signal processing,the extracted infor-mation is more accurate,reliable,and the hydro-phone signals can be communicated to electronic e-quipment on the surface of the water through a va-riety of real time bus,can also be used as stand alone test system which has information processing and preservation. |
