SYNCHRONIZING SYSTEM AND METHOD FOR SYNCING EVENT LOGS FROM DIFFERENT MONITORING SYSTEMS

摘要

A synchronizing system and method receive event log data from different monitoring systems. The event log data represents operational events of a powered system recorded by the monitoring systems and corresponding times of the operational events. The monitoring systems record the event log data at different time bases and/or sampling rates. The event log data from the monitoring systems are temporally correlated with each other by changing the time bases of the event log data to a common time base and/or by changing a visual presentation of the event log data such that the event log data are visually presented with a common time scale responsive to the sampling rates differing from each other.

1. A method comprising:
receiving first event log data from a first monitoring system of a powered system, the first event log data representing first operational events of the powered system recorded by the first monitoring system and corresponding first times at which the first operational events are recorded by the first monitoring system as occurring; receiving second event log data from a second monitoring system of the powered system, the second event log data representing second operational events of the powered system recorded by the second monitoring system and corresponding second times at which the second operational events are recorded by the second monitoring system as occurring, wherein the first monitoring system records the first event log data at one or more of a first time base that differs from a second time base at which the second monitoring system records the second event log data or a first sampling rate that differs from a second sampling rate at which the second monitoring system records the second event log data; and temporally correlating the first event log data with the second event log data by one or more of:
changing one or more of the first time base of the first event log data or the second time base of the second event log data to a common time base; orchanging a visual presentation of one or more of the first event log data or the second event log data on a display device such that the first event log data and the second event log data are visually presented with a common time scale responsive to the first sampling rate of the first event log data differing from the second sampling rate of the second event log data.
