Recording wave control method of the converter valve control device

The present invention discloses a HVDC valve control apparatus and control method for recording wave transducer, comprising mutually connected with the CPU and FPGA recording wave function, FPGA and connected to the expanded memory management processor communication, the communication management processor sets a useful a communication interface with the host computer, the communication management processor is also connected to a temporary memory; Valve equipment when an abnormality occurs, or the data needs to be saved, FPGA fault recording start, the original recorded data stored in the extended memory ; when the host computer needs to read data, data read out by the FPGA from the expansion memory, the cache, the processor reads the communication management data from the dual port RAM, dual-port RAM by FPGA's bus, to transmit through the communication interface PC. Wave control apparatus and recording control method of the present invention employs the communication management processor and FPGA, respectively, communicate with the host computer and recording recorded data of their duties, improve the processing speed, to ensure the stability of operation of the device.
