A method and system for analyzing operational data for diagnostics of locomotive malfunctions

摘要

A method for analyzing fault log data (200) and snapshot operational parameter data (25) from railroad locomotives and other large land-based, self-powered transport equipment, undergoing diagnostics is provided. A receiving step (72) allows for receiving fault log data comprising a plurality of faults from the equipment. Respective executing steps allow for executing a set of noise-reduction filters (27) upon the received fault log data to generate noise-reduced fault log data, and for executing a set of candidate snapshot anomalies (28) upon the noise-reduced data to generate data predictive of malfunctions of the equipment.
