Design and application of automatic calibration data download software for early warning network

There are different types of instruments in the early warning network stations, and the download methods of calibration data are also different. In this study, the strong earthquake instrument system of the early warning network station of Beijing Earthquake Agency was calibrated twice per year. An automatic download calibration file software was designed using Python to avoid the errors that occur and the time required for the manual download of calibration files during daily operation and maintenance. The one-click download function for the calibration data of different instruments is convenient for station operation and maintenance. The software has been applied in the calibration data download of Beijing early warning network.
