A process and system for developing predictive diagnostics algorithms in a machine

摘要

A process and system for developing an algorithm for predicting failures in a system, such as a locomotive, having a plurality of subsystems is provided. The process allows for conducting a failure mode analysis for a respective subsystem so as to identify target failure modes of the subsystem and/or collecting expert data relative to the respective subsystem. The process includes a step for identifying, based on the identified failure modes and/or the collected expert data, one or more signals to be monitored for measuring performance of the respective subsystem. A generating step allows for generating, based on the monitored signals, a predicting signal indicative of the presence of the identified target failure modes in the respective subsystem.
