Abstract

L'invention concerne un système automatique permettant d'arrêter de manière sûre les véhicules et d'évacuer les obstacles sur les passages à niveau non surveillés, ainsi qu'un procédé d'application de ce système. Les lignes de commande du mécanisme de commande du système décrit sont reliées aux circuits de commande respectifs d'un mécanisme avertisseur, d'un dispositif d'arrêt des véhicules et d'un mécanisme de courroie de transport. Lorsque le système est opérationnel, l'unité de détection du mécanisme de commande coopère avec les voies de chemin de fer et reçoit un signal indiquant le déplacement du train. Le mécanisme de courroie de transport est installé entre les rails et des deux côtés de ces derniers, la zone isolée se trouve à l'extérieur de la courroie de transport, et le dispositif d'arrêt des véhicules est installé à l'extérieur de la zone isolée. L'unité émettrice de signal d'alarme du mécanisme avertisseur est placé dans une position adéquate. Lorsqu'un train approche le passage à niveau, le mécanisme de commande transmet une instruction entraînant l'émission par le mécanisme avertisseur d'un signal acoustique, lumineux ou analogue pour avertir les véhicules et les piétons de l'approche du train, et au même moment le dispositif d'arrêt des véhicules est activé de manière à se placer dans un état dans lequel il arrête les véhicules, et empêche les véhicules et les piétons se trouvant à l'extérieur du passage à niveau de pénétrer sur ce dernier, puis les objets tels que véhicules sont déplacés à l'extérieur du passage à niveau par le mécanisme de courroie de transport activé, ce qui permet d'arrêter de manière sûre les véhicules et d'éliminer les obstacles, et d'éviter ainsi le risque d'accidents.
