时间同步监测分析系统的开发与应用

Development and Application of a Time Synchronization Monitoring and Analysis System

介绍了时间同步监测分析系统的设计和实现。提出了基于实时监测层、实时分析层和综合应用层3层架构的时间同步监测分析技术框架,讨论了时间偏差抑制、时间一致性分析、自守时精度分析、误差综合诊断、网络时间协议(NTP)时间戳性能监测等关键技术。介绍了系统的工程实现,探讨了时钟状态分析、时间误差诊断和系统性能分析等系统应用。

The implementation and application of a time synchronization monitoring and analysis system are described.A time analysis synchronization technical framework architecture based on three-layer,real-time monitoring,real-time analysis and comprehensive application is presented.Some implementing methods are presented,which mainly include error control based on the autoregressive integrated moving average（ARIMA） model,global time consistency analysis,self-running precision analysis,correlation analysis of error diagnosis,and NTP timestamp-based performance monitoring.Engineering implementation of the system is dealt with,and system applications including clock state maintenance analysis,time error intelligent diagnosis and system performance and load analysis are discussed.
