CA 2291228

The present invention discloses a system (10) and method for diagnosing and validating a machine with waveform data generated therefrom. In this invention, historical waveform data (18) are obtained from machines having known faults (20) along with corresponding actions for repairing the machines and are used to develop fault classification rules. The fault classification rules are stored in a diagnostic knowledge database (12). The database of classification rules are used to diagnose new waveform data (30) from a machine (32) having an unknown fault.

La présente invention concerne un système (10) et un procédé permettant de diagnostiquer et de valider une machine à partie de données de signal qu'elle produit. Le procédé de l'invention consiste à prendre des données historiques se rapportant, d'une part à un signal (18) provenant de machines affectées de défauts connus (20), et d'autre part à des actions correspondantes visant à réparer les machines, puis à utiliser ces données pour mettre au point des règles de classification des défauts. On range les règles de classification des défauts dans une base de connaissances de diagnostic (12). La base de données des règles de classification sert à faire le diagnostic des données de nouveaux signaux (30) provenant d'une machine (32) affectée d'un défaut inconnu.
