Patent

CA 2474757

Track and track/vehicle analyzers for determining geometric parameters of tracks, determining the relation of tracks to vehicles and trains, analyzing the parameters in real-time, and communicating corrective measures to various control mechanisms are provided. In one embodiment, the track analyzer includes a track detector and a computing device. In another embodiment, the track/vehicle analyzer includes a track detector, a vehicle detector, and a computing device. In other embodiments, the track/vehicle detector also includes a communications device for communicating with locomotive control computers in lead units, locomotive control computers in helper units, and a centralized control office. Additionally, a method for determining and communicating an optimized control strategy is provided. A method for dynamically modeling vehicle behavior, determining probabilities for derailment, and communicating recommended actions is also provided. The analyzers improve operational safety and overall efficiency, including fuel efficiency, vehicle wheel wear, and track wear, in railroad systems.

L'invention concerne des analyseurs de voie et de voie/v~hicule permettant de d~terminer des param­tres g~om~triques de voies, de d~terminer le rapport de voies avec les v~hicules et les trains, d'analyser les param­tres en temps r~el et de communiquer des mesures de correction ~ des m~canismes de commande divers. Dans un mode de r~alisation, l'analyseur de voie comprend un d~tecteur de voie et un dispositif informatique. Dans un autre mode de r~alisation, l'analyseur de voie/v~hicule comprend un d~tecteur de voie, un d~tecteur de v~hicule comprend un d~tecteur de voie, un d~tecteur de v~hicule et un dispositif informatique (218). Dans un autre mode de r~alisation, le d~tecteur de voie/v~hicule comprend ~galement un syst­me de communication (216) permettant d'assurer la communication avec des ordinateurs (250) de commande de locomotive dans des unit~s de tÚte, avec des ordinateurs (254) de commande de locomotive dans des machines de queue, et un bureau (260) de commande centralis~. L'invention concerne en outre un proc~d~ de d~termination et de communication d'une strat~gie de commande optimis~e, un proc~d~ de mod~lisation dynamique d'un comportement de v~hicule, de d~termination de probabilit~s en cas de d~raillement et de communication d'actions recommand~es. Les analyseurs contribuent ~ une sÛret~ op~rationnelle et une efficacit~ am~lior~es, y compris l'efficacit~ du combustible, l'usure des roues de v~hicule et l'usure de la voie dans des syst­mes de voie ferr~e.
