Variable exception reporting

摘要

A method of analyzing train operational data recorded during each run of a train and transferred to a processing station. Operational and informational parameters are derived from the recorded operational data for each run. The operational and identification parameters and the corresponding operational data are stored as a standard database record for each run. The operational parameters are compared to selected exception values and the variance of the comparison are stored with the standard operational database record for each run. A search is then performed of the stored standard database records based on one or more of operational parameter, identification parameter, operational data and variance.
