Abstract

L'invention porte sur un système de gestion de charges, les alimentant et en vérifiant l'état au moyen d'un signal de puissance et d'un signal de données. Les différentes charges sont réparties en groupes dotés chacun d'un module de commande. Un contrôleur central assurant la transmission du courant émet un signal de contrôle vérifiant ou contrôlant l'état de l'ensemble des charges, à destination d'au moins un module de commande, et reçoit en retour d'au moins un module de commande un signal informant sur l'état des charges. Un seul module de commande peut gérer une variété de charges de puissance différente.
