Abstract

Quand il n'y a pas suffisamment de puissance dans un système comprenant un dispositif de contrôle et un dispositif devant être contrôlé par le dispositif de contrôle, le dispositif devant être contrôlé doit connaître le statut du dispositif devant être contrôlé, ou bien il doit connaître le procédé de contrôle qui est utilisé afin de réduire la puissance du dispositif devant être contrôlé et économiser sa puissance. Dans ce cas, le contrôle devient complexe. Afin de résoudre ce problème, la présente invention se rapporte à un dispositif de contrôle qui est connecté, sur un réseau, à une pluralité de dispositifs devant être contrôlés qui consomment de la puissance, ledit dispositif de contrôle contrôlant ladite puissance. Le dispositif de contrôle selon l'invention comprend : un module de réception qui reçoit, d'une source externe, une demande de réduire une consommation d'énergie ; et un module de transmission qui transmet, à un dispositif devant être contrôlé, la demande de réduction de la consommation d'énergie. Quand une demande de réduire une consommation d'énergie est reçue par le module de réception, ledit dispositif de contrôle commande qu'une demande de réduire la consommation de puissance soit transmise, du module de transmission au dispositif devant être contrôlé.
