摘　　要：新疆天文台望远镜产生的观测数据通过数据专线传输到新疆天文台本部数据中心进行长期存储。采用rsync进行数据传输,传输过程中没有详细的日志记录信息,无法对传输情况进行统计分析。通过调研新疆天文台数据传输的需求,设计并开发了新疆天文台观测数据传输日志系统。系统以新疆天文台南山站、奇台站的数据存储服务器和新疆天文台本部长期存储为基础,设计了日志系统的整体架构,实现了数据传输过程的日志记录。系统基于shell多线程技术及Qt框架,开发了后台服务程序及日志系统软件界面,实现了日志分析、统计备份与数据传输的可视化页面。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.
