Abstract

L'invention concerne un dispositif de commande d'un système de trafic. Ce dispositif comprend une unité de calcul, un premier terminal de communication et un second terminal de communication. Le dispositif est configuré pour établir, via le premier terminal de communication, une première connexion à un autre dispositif pour commander le système de trafic. Le dispositif est également configuré pour établir, via le second terminal de communication, une seconde connexion à un élément réglable du système de trafic. L'unité de calcul est configurée pour calculer des informations de réglage pour l'élément réglable. Le dispositif est configuré pour utiliser des informations système pour décider si le dispositif est autorisé à transférer les informations de réglage à l'élément réglable et, si tel est le cas, pour délivrer en sortie les informations de réglage via le second terminal de communication et la seconde connexion. Les informations système sont des informations de connexion qui sont délivrées en sortie par les éléments réglables et sont transmises, via la seconde connexion, aux dispositifs pour commander le système de trafic. Le dispositif est également configuré pour synchroniser les informations de réglage avec l'autre dispositif pour commander le système de trafic via le premier terminal de communication et la première connexion. Le dispositif peut également être configuré pour vérifier la première connexion quant à une défaillance et, si une défaillance est détectée dans la première connexion, pour établir une connexion alternative à l'autre dispositif pour commander le système de trafic via l'élément réglable.
