Digital hydrophoneIt is a new type of underwater acoustic signal acquisition unit that integrates traditional analog hydrophones, amplification and conditioning circuits, acquisition, storage, Ethernet transparent switching, and simple signal processing. The hydrophone has two adaptive power grid ports; Using PTP protocol to transmit business data and synchronization messages synchronously collected between hydrophones via Ethernet; Communication, synchronization, and power supply functions between hydrophones can be achieved with only one cable, greatly reducing the number of cables on the basis of traditional solutions through multiplexing link technology. It has broad market application prospects in the field of ocean engineering.

Digital hydrophoneData collection and signal processing technology:

In multi element array underwater acoustic detection, it involves multi-channel optical signal detection and complex signal processing. In this regard, Shenzhou Puhui has proprietary technologies for large-scale array detection, including high-precision and high-capacity synchronous signal acquisition and control technology based on unified clock and distributed time difference correction, high-capacity continuous data acquisition and parallel frame structure signal processing data exchange technology based on composite structure FPGA and multi-core DSP, embedded adaptive parameter setting, and high-capacity optoelectronic coherent signal processing technology.

Through data collection and signal processing, digital acoustic signals of various hydrophone detection elements can be obtained. These signals must be managed through specialized databases and transmitted through different interfaces in order to be provided to users for use. In this regard, Shenzhou Puhui provides technical support for multiple application oriented and complex data structure database management and data product generation technologies based on the real-time distributed simulation support platform AppSTS.

For applications in different fields, application support units need to provide database interfaces, data transmission interaction control, and specialized software development technical support for specialized applications.
