System and method for predicting impending failures in a locomotive
First Claim
1. A computer-based method for predicting impending failures in a locomotive having a plurality of subsystems comprising:
- storing log data indicative of respective incidents that may occur as each of the subsystems is operative;
detecting predetermined trend patterns in the incident log data;
mapping each respective detected trend pattern into a respective prediction of an impending failure of a respective one of the subsystems of the locomotive; and
informing a respective user about the respective predicted failure so as to allow the user to take corrective action before the predicted failure occurs.

Abstract
A computer-based method and system for predicting impending failures in a system, such as a locomotive, aircraft, power plant, etc., having a plurality of subsystems is provided. The method allows for storing log data indicative of respective incidents or events that may occur as each of the subsystems is operative. A detecting step allows for detecting predetermined trend patterns in the log incident data. A mapping step allows for mapping each detected trend pattern into a respective prediction of an impending failure of a respective one of the subsystems of the locomotive, and an informing or outputting step allows for informing a respective user of the failure prediction so as to allow the user to take corrective action before the predicted failure occurs.

16. A system for predicting impending failures in a locomotive having a plurality of subsystems comprising:
-
an storage unit having a first subsection for storing log data indicative of respective incidents that may occur as each of the subsystems is operative;
a trend detector coupled to receive the log data from the storage unit to detect predetermined trend patterns in the received log data;
a matching module coupled to receive a detected trend pattern and including a mapping module configured to map each detected trend pattern into a respective prediction of an impending failure of a respective one of the subsystems of the locomotive; and
means for informing a user indicating the predicted failure so as to allow the user to take corrective action before the impending failure actually occurs. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
