Research on Visualized Playback Function of the Train Operating Status Based on PHM System

This paper studies the visualized playback function of the train operating status for high speed EMU and applies it in the PHM system. It can provide the information support for operation staff to analyze the trace and parameter changes at a certain time. This study realizes the playback of the train operating status based on the train GPS data and operating status data and the visual effect is represented in the form of curve plotting with different kinds of plotting speeds. It combines the train operating parameters with the running track status to display the train running trace dynamically and the change of relevant state parameters, and hence guarantees the parameter analysis based on train operation track.
