Abstract

L'invention concerne un serveur d'observation au-dessus du sol comportant une partie de réception de données (401), une partie d'observation des données (402), et une partie de stockage (410). La partie de stockage (410) indique un instrument embarqué spécifié, qui est demandé à des fins d'observation par un programme d'observation, comme cible d'observation, et stocke un tableau de gestion des programmes d'observation (408) ayant un enregistrement de l'instrument embarqué cible d'observation pour chaque programme d'observation d'une pluralité de programmes d'observation. La partie de réception de données (401) reçoit des données compilées des instruments embarqués en provenance de dispositifs de compilation de données (100) qui sont installés dans de multiples trains et qui envoient des données compilées selon des intervalles prédéterminés. La partie d'observation des données (402) détecte des données compilées de mauvais fonctionnement se produisant dans les instruments embarqués sous la forme de données compilées détectées en fonction des données compilées reçues (601), et en fonction des données compilées détectées, recherche dans le tableau de gestion des programmes d'observation (408) un programme d'observation demandant l'observation des instruments embarqués fonctionnant mal enregistrés dans les données compilées détectées, et spécifie le programme d'observation qui permettra de notifier le mauvais fonctionnement dans les instruments embarqués.
