Problems solved by technology

[0008] The current fiber channel data interface cards are mainly used in specific data acquisition industries. There are mainly fiber channel data interface cards using MCU as the control core, and fiber channel data interface cards using FPGA and PCI bus. These two types of fiber channel The data interface card is basically enough for a single device and small-capacity data acquisition or monitoring, but in the face of a large-capacity, high-speed, high-fidelity optical fiber network, these two types of fiber channel data interface cards are not competent. At the same time, the existing The fiber channel data interface card configuration capability is weak, and only simple configuration can be realized
