Abstract

Système de distribution automatique de puissance par réseau de communication mobile. Le système de distribution automatique de puissance comprend : un terminal de distribution automatique de puissance ; un serveur de gestion ; une première unité de communication pour la transmission et la réception de signaux entre le terminal de distribution automatique de puissance et le serveur de gestion ; et une seconde unité de communication pour la transmission et la réception de signaux entre le terminal de distribution automatique de puissance et le serveur de communication sur la base du mode de communication CDMA (accès multiple par répartition de code). Le terminal de distribution automatique de puissance utilise la première ou la seconde unité de communication pour transmettre un signal de défaillance au serveur de gestion et exécute une commande automatique via le réseau de fourniture de puissance à l'équipement in situ où une défaillance a été détectée si le serveur n'envoie par un signal d'accusé de réception (ACK) en réponse au signal de défaillance dans un laps de temps prédéterminé.
