Abstract

L'invention concerne un ventilateur de jet intelligent utilisant l'IdO / la TIC, et un système intégré de maintenance et de gestion associé. Un ventilateur de jet intelligent utilisant l'IdO / la TIC selon un mode de réalisation de la présente invention comprend : un ventilateur de jet axial comprenant un moteur, un ventilateur tournant en fonction d'un entraînement du moteur, et un boîtier logeant le ventilateur et le moteur ; un module de capteur pour mesurer une température d'un palier du moteur, des états de vibration du ventilateur de jet axial dans des directions verticale, horizontale et axiale, et des états d'inclinaison du ventilateur de jet axial dans les trois axes ; et un émetteur sans fil, lequel est installé sur un côté de la périphérie extérieure du boîtier et lequel transmet sans fil des données mesurées dans le module de capteur à un serveur de gestion externe.
