Description du projet
Une technologie innovante pour l’inspection ferroviaire
Les parties prenantes des systèmes ferroviaires fonctionnant 24 heures sur 24, 7 jours sur 7, toujours plus vite et avec un nombre croissant d’utilisateurs doivent relever le défi de l’inspection des principaux précurseurs d’accidents tels que les ruptures de rails et les gauchissements de la voie. Les systèmes actuels de surveillance ferroviaire, tels que les véhicules laboratoire, les trains d’auscultation autonomes et les chariots poussés manuellement, impliquent une perturbation du trafic ferroviaire et sont coûteux. Le projet vmRail, financé par l’UE, propose la première technologie fiable et abordable permettant d’évaluer les voies ferrées et le matériel roulant. Cette technologie combine des réseaux de capteurs, la simulation informatique et le traitement du signal pour comparer les données relatives aux irrégularités de la géométrie des voies et l’évolution de l’usure et de la fatigue en temps réel. Qui plus est, le système vmRail améliore simultanément les opérations de maintenance des véhicules et des voies, la sécurité des trajets et le confort des passagers.
Objectif
Detection and rectification of the main accident precursors (broken rails and track buckles) are one of the major issues for all players in railway systems that operate 24/7, at increasing speed, and with a growing number of users. Current inspection tools used for railway monitoring such as laboratory vehicles, self-powered auscultation trains and manually pushed carts require disruption of the railway traffic and are expensive.
Additionally, comfort is an essential factor besides maintenance in the competition between railway and other means of transportation. Ride comfort is a complex notion that represents an important criterion when examining the dynamics of railway vehicles and needs to be considered for their modelling and behaviour evaluation.
vmRail is the first reliable and cost affordable technology able to combine sensor networks, computer simulation and signal processing to evaluate the state of railways and rolling stocks by comparing track geometry irregularities data and wear & fatigue evolution in real time. Therefore, vmRail simultaneously improves vehicle and track maintenance operations, ride safety, and passenger comfort.
With fleets and infrastructures being operated for 30 to 50 years and maintenance accounting for ~50 % of overall cost, the main goal of railway and underground operators is to cost-efficiently increase fleet availability and reliability. Railway and underground operators will benefit of using vmRail by avoiding unnecessary replacements and results in less network disruption due to unplanned/planned maintenance. Moreover, our technology is up to 90% less expensive than current laboratory trains since is based on computing vision, accelerometers and simulations.
