The application gateway receives the relay protection upload data, determines whether the data frame is correct in accordance with the frame head, the frame, the frame length, and the calibration mode; then protocols the complete data frames. According to the device number position in the custom protocol description information, the corresponding upload device number is read, and the corresponding upload device number is read, and the protocol number corresponding to the device number is found in the device information table. The data frame type is then found according to the command identification position. The data area analysis is subsequently performed, and the corresponding data item is found in accordance with the protocol number, data frame number, and the starting position of the custom protocol. According to the data format and coefficients in the data item, the actual value size of u...
