CA 2571804

A novel method and system for fault identification is provided. A test head that is operable to generate a test signal along a pathway is employed. The test head is based on time domain reflectometry, and is thus operable to provide an estimated physical distance of where a fault occurs along the pathway. The response test signal is matched with a known set of information about the cable and junctions and other components associated with the pathway, including information about the physical location of those components. As part of the matching, an actual real-world physical location can be identified as to where the fault likely occurs, thereby reducing the need for a service technician to attempt to physically locate the fault himself.

L~invention concerne un procédé et un système originaux d~identification de défaut. Une tête d~essai qui est opérationnelle pour générer un signal d~essai le long d~un chemin d~accès est employée. La tête d~essai se base sur la réflectométrie de domaine temporel et donc est opérationnelle pour indiquer une distance physique estimée du lieu où un défaut se produit le long du chemin d~accès. Le signal d~essai de réponse est mis en correspondance avec un ensemble connu d~informations concernant le câble et les jonctions et d~autres composants associés au chemin d~accès, comprenant des informations concernant l~emplacement physique de ces composants. Dans le cadre de la mise en correspondance, un emplacement physique exact du monde réel peut être identifié quant au lieu où le défaut se produit probablement, réduisant de ce fait le besoin pour un technicien d~entretien de tenter de localiser physiquement le défaut lui-même.
