Abstract

La présente invention aborde le problème de la fourniture efficace d'une notification d'informations importantes en fonction du degré de priorité d'un événement. La présente invention comprend : une unité de détection d'événement pour, en utilisant des résultats d'imagerie de caméras qui ont chacune une plage d'imagerie comprenant une partie proche d'une face latérale d'un train, détecter un événement à notifier à une personne de surveillance ; une unité de stockage pour stocker, et associer les uns aux autres, les résultats d'imagerie des caméras et les résultats de détection de l'événement ; et une unité de commande d'affichage pour afficher et fournir des informations concernant l'événement sur un dispositif d'affichage prédéfini et notifier la personne de surveillance des informations. L'unité de détection d'événement détecte en tant que premier événement un événement prédéfini, et détecte en tant que second événement un événement ayant un degré de priorité de notification inférieur à celui du premier événement. L'unité de commande d'affichage affiche et fournit les résultats de détection du premier événement et du second événement, et comporte individuellement : un premier moyen de réception d'opération pour vérifier des détails du premier événement ; et un second moyen de réception d'opération pour vérifier des détails du second événement.
