Design and Implementation of Xinjiang Astronomical Observatory Observation Data Transmission Log System

The observation data generated by Xinjiang Astronomical Observatory(XAO) telescope was transmitted to the data center at XAO headquarters for long-term storage through the dedicated transfer line. Statistical analysis cannot be performed due to the lack of detailed log records during transmission using rsync. The data transmission log system of XAO was designed and developed on the basis of fully investigating the data transmission demand. Based on the data storage server of Nanshan Station, Qitai Station and the long-term storage server at the XAO headquarters, the overall architecture of log system was designed and the logging of the data transmission process was realized. The shell multi-threading technology and qt framework were adopted to develop the back-end service program and system software interface which realized log analysis, data statistics, log backups and data transfer visualization page.
