CA 2238946

The invention relates to a method and apparatus for checking a plurality of electrical drive mechanisms (1). These mechanisms may in particular be drive mechanisms for railroad switches. It is contemplated that at the plurality of electrical drive mechanisms, measured values are picked up at the same time, and the signals describing them are provided with drive mechanism- specific identifier. These thus-identified signals are then carried without interruption, on-line, to a data processing system (6), where they are compared with desired values available there. If a signal deviates from a desired value, an error is indicated for the particular drive mechanism (1) at which the signal originated.

L'invention concerne un procédé et un dispositif permettant de contrôler une pluralité de dispositifs électriques d'entraînement (1), notamment des mécanismes d'entraînement d'aiguilles de chemins de fer. Selon l'invention, on recueille en même temps des valeurs au niveau de ladite pluralité de dispositifs électriques d'entraînement et les signaux qui décrivent ces valeurs sont pourvus de codes d'identification spécifiques à chaque dispositf d'entraînement. Les signaux ainsi identifiés sont ensuite transmis directement en ligne à un système de traitement de données (6) qui les compare à des valeurs de consigne. Lorsqu'un signal diffère d'une valeur de consigne, un défaut du dispositif d'entraînement (1) d'où le signal est parti est indiqué.
