CA 2387917

A process and system for developing an algorithm for predicting failures in a mobile asset, such as a locomotive (10), 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.

L'invention concerne un procédé et un système permettant de développer un algorithme de prédiction de panne dans un équipement mobile, tel qu'une locomotive (10), ce système possédant plusieurs sous-systèmes. Le procédé permet d'effectuer une analyse d'un mode panne dans le sous-système correspondant, de manière à identifier des modes panne cibles du sous-système et/ou à collecter des données expertes relatives audit sous-système correspondant. Le procédé consiste à identifier, en fonction des modes panne identifiés et/ou des données expertes collectées, au moins un signal à surveiller afin de mesurer une performance du sous-système correspondant; et à générer, en fonction des signaux surveillés, un signal de prédiction indicateur de la présence des modes panne cibles identifiés dans le sous-système correspondant.
