High-speed wave recording device with steady-state wave recording function

The invention provides a high-speed wave recording device with a steady-state wave recording function, and the device comprises a processor module which comprises an FPGA processor and an ARM processor; an SDRAM and an SSD; the SDRAM and the SSD are connected with the FPGA processor through different interfaces; the FPGA processor is used for receiving and preprocessing the recording data of the valve control equipment and storing the recording data of the valve control equipment into the SDRAM; the data transfer module is also used for transferring the recording data of the valve control equipment in the SDRAM into the SSD; and the data reading module is also used for reading corresponding data from a corresponding area of the SSD according to a data reading request of the ARM processor. By adopting the SSD, large-capacity and high-rate data of the flexible direct current converter valve can be continuously stored in real time, meanwhile, the problem that data are lost due to the fact that the data are not t
