Abstract

La présente invention se rapporte à un dispositif de gestion et de commande permettant d'améliorer le rendement de conversion d'énergie d'un dispositif de conversion d'énergie qui convertit les états énergétiques. Ledit dispositif de gestion et de commande comprend un dispositif de gestion générale (1), un dispositif de commande de localisation (3) disposé à chaque endroit commercial, un dispositif de commande de dispositif (4) raccordé au dispositif de commande de localisation (3) et un dispositif (5) dont le fonctionnement est commandé par le dispositif de commande de dispositif (4). Le dispositif de commande de localisation (3) sélectionne le programme de commande de dispositif qui est le plus approprié pour un dispositif qui doit être commandé, parmi une pluralité de programmes de commande de dispositif stockés dans le dispositif de commande de localisation, et commande le fonctionnement du dispositif. Le dispositif de gestion générale (1) détermine la présence/l'absence et le type de fonctionnement défectueux du dispositif (5) sur la base d'une valeur de condition d'environnement externe obtenue d'un capteur externe (6) et d'une valeur de condition d'environnement interne obtenue d'un capteur interne (7), ordonne des mesures de correction, transmet des données de maintenance préventive et calcule et transmet l'effet des économies d'énergie de fonctionnement.
