Abstract

On acquiert et transmet en temps réel l'information sur l'état opérationnel de l'équipement de collecte d'information vers le contrôleur à distance d'une station de suivi par le contrôleur d'une station d'observation qui commande l'équipement de collecte d'information entre la station d'observation à distance équipée d'un équipement d'information et la station de suivi qui échange les informations avec la station d'observation. Le contrôleur à distance vérifie l'équipement de collecte d'information afin d'assurer un fonctionnement normal de l'information reçue à l'état opérationnel et redéfinit le contrôleur de station d'observation si le fonctionnement de l'équipement de collecte d'information est anormal. Dans cette structure, si le contrôleur de station d'observation s'arrête, ce dernier avec l'aide d'une ligne d'échange d'information existant entre celui-ci et le contrôleur à distance redéfinit l'équipement de collecte d'information avec des moyens de remise à zéro branchés à partir d'une station pivot à proximité du contrôleur de station d'observation.
