Abstract
A system and method for on-board or rail-side monitoring of train track, wheels, running gear, and other railway systems' component health by constant monitoring of acoustic, vibration, and potentially other modalities is described. These data are then processed to arrive at the track health data per track location, arrive at specific vehicle component health, and ride quality data from either passenger comfort or cargo damage protection of view.
Claims19
1) A system for monitoring railway equipment condition, comprising:
- at least one data acquisition and aggregation unit attached to a rail car;
- an analysis system for analysis and fusion of acquired sensor data to assess rail car and/or track condition;
- and
- analyzing the data for characterization of the rail and or track status.
8) A system for monitoring railway equipment condition, comprising:
- at least one data acquisition and aggregation unit attached to or in proximity to the rail track;
- an analysis system for analysis and fusion of acquired sensor data to assess rail car and/or track condition;
- and
- analyzing the data for characterization of the rail and or track status.
15) A method for monitoring a railcar or railroad track, the method comprising:
- at least one sensor mounted or connected to a railcar;
- generating electrical signals corresponding to the sensor data;
- analyzing the generated electrical signals to extract at least one feature of the generated signals;
- comparing at least one feature to a plurality of rail component condition anomalies.
