[0063] Working principle: The portable fiber optic data acquisition, analysis and storage device proposed in this embodiment includes an AC / DC power supply, a main control card and a fiber optic / power card arranged inside the chassis body; the main control card and the fiber optic / power card communicate through the PCIE bus; data transmission is performed through DMA data direct transmission, thereby realizing data interaction between the main control card and the fiber optic / power card, and has the characteristics of high integration, low cost, small size and easy carrying.

[0064] Embodiment 2:

[0065] This embodiment describes the specific structure of the optical fiber / power supply card based on the above-mentioned embodiment 1.

[0066] The optical fiber / power supply card includes an FPGA module and a power supply module;

[0067] The input end of the power module is connected to the output end of the AC / DC power supply, and the output end of the power module is connected to the power interface of the optical fiber / power card;

[0068] The FPGA module is connected to the power module and the host computer;

[0069] The power supply module is used to convert the voltage obtained from the AC / DC power supply into multiple voltages with different amplitudes;

[0070] The FPGA module is used to transmit the multiple voltages with different amplitudes to the host computer through MDA transmission.

[0071] Furthermore, the optical fiber / power supply card also includes a current monitoring module,

[0072] The current monitoring module includes an ADC module and a Hall current sensor;

[0073] The input end of the Hall current sensor is connected to the power interface, and the output end is connected to the ADC module;

[0074] The output end of the ADC module is connected to the FPGA module;

[0075] The Hall current sensor is used to convert the current signal obtained from the power interface into a voltage signal;

[0076] The ADC module is used to collect the voltage signal output from the Hall current sensor in an oversampling mode;

[0077] The FPGA module is also used to determine whether the magnitude of the current signal exceeds a set current threshold, and if so, generate a shutdown instruction to shut down the corresponding power supply.

[0078] Furthermore, the optical fiber / power supply card also includes a DDR storage module;

[0079] The DDR storage module is connected to the FPGA module.

[0080] Working principle: The optical fiber / power card mainly includes logic device FPGA, storage device DDR, power module, current monitoring module, SPF+ optical fiber interface, MT optical fiber interface, power interface and other modules.

[0081] FPGA is used to realize the control of power module, the communication of optical fiber data, the control of current monitoring module, and the data transmission with the host computer through PCIE bus and DMA direct data transmission.

[0082] The current monitoring module uses a 16-bit ADC and a Hall current sensor. The Hall current sensor converts the current on the output power supply into a voltage, which is then collected by the ADC. The sampling clock used by the ADC is an internally generated 125MHz clock. In order to make the collected voltage more accurate, an oversampling mode is used. The FPGA determines whether the collected current signal exceeds the set threshold based on the current threshold set by the host computer. If it exceeds the set threshold, the corresponding power supply is automatically turned off.

[0083] The power module uses multiple power chips with a maximum current of 20A to convert the 28V DC power input of the AC / DC power supply into 28V, 12V, 5V, -5V, and -40V power supplies. Then, the FPGA uses DMA to control the output of each DC power supply through the host computer.

[0085] Since the capacity of the DDR connected to the FPGA is limited, the collected data needs to be exported in real time to a larger and non-volatile hard disk. Therefore, the main control card and the FPGA of the optical fiber / power card communicate via PCIe, and the DMA method is used to send the DDR cached data to the main control card, and the latter writes the data to the SSD solid state drive. The solid state drive here can use the serial hard disk interface SATA, or the storage hard disk NVMe based on the PCIe interface. This embodiment uses a combination of 1TBSATA SSD and 2 2T NVME SSDs to achieve long-term collection and storage.
