The new sonar system not only plays an important role in military field, but also in civil detection. A complete sonar system includes front-end acquisition, signal processing, display control, storage and playback, and how to provide high-speed, reliable data transmission and system interconnection for the sonar system is the focus of its research.

The design of this paper is realized in a standard CPCI frame of 6U size card. Based on the research and summary of the core technology, this paper uses the design method of module, and emphasizes the hardware design of the whole board in this paper. The software platform, test program and driver are also introduced. This design adopts processor architecture based on DSP FPGA, applies high-speed serial transmission technology and control protocol, uses optical fiber transmission technology on physical channel, and combines the topology of TS201 chip high-speed LINK channel and digital signal processing platform. Design and implementation of high-speed and stable data transmission and interconnection structure. On the choice of FPGA chip, based on the FPGA chip of Virtex5 series of Xilinx Company, this paper adopts the modular design idea to realize the logic design of the conversion bridge from PCI bus to DSP bus and the logic design of optical fiber channel control protocol respectively. In the selection of DSP chip, ADI TS201DSP chip is used as the core data processing chip. Thus, the data checksum algorithm of single board is realized. In this design, two optical fiber channels with different bandwidth are integrated, and the redundant design is adopted. Each bandwidth fiber channel has a hot backup, which fully ensures the reliability. After the completion of hardware and software design, this paper builds a complete hardware test platform to test the design indicators, and gives the test results, the test data accord with the original design indicators. Using the modularization design idea, the optical fiber transmission hardware card based on CPCI and DSP FPGA is completed. Compared with the traditional hardware card based on CPCI data transmission system, the single board realizes the minimum system; Single board has a variety of bandwidth optical fiber data channel; hardware design to achieve modularization. The final implementation of this application design, on the premise of guaranteeing the reliability of sonar system data interconnection, greatly improves the transmission efficiency and has high engineering application value.
