Patent

CA 2288875

The invention relates to a monitoring device which can monitor automatically and in real time the electric consumption in a house, in premises or any other building while controlling the total consumption of the complete electric installation in a predetermined area, said system comprising means for measuring and indicating the instantaneous consumption, and selection and storage of various consumption levels. All of these operations are governed by control and processing means. There are also provided indicators for the consumed power and means for entering and displaying data so that the user can control the accumulated consumption, set a limit value of the energy cost forecast and send a warning signal when such limit has been exceeded, and additionally prevent any devices from remaining connected when leaving the premises, this being extremely dangerous. The system takes measurements at different points in the installation and makes automatic connections/disconnections of certain loads in order to avoid overcurrents in the electric network.

L'invention concerne un dispositif de surveillance permettant de surveiller automatiquement et en temps réel la consommation électrique dans une habitation, dans un local ou dans tout autre type d'enceinte ce qui rend possible le contrôle de la consommation totale de l'installation complète ou d'une zone déterminée. Le dispositif de surveillance est doté de moyens de mesure (1) et d'indication (5) de consommation instantanée, ainsi que de sélection (4) et de stockage de différents niveaux de consommation. Tout ceci est commandé par des moyens de contrôle et de traitement (3). Le dispositif de surveillance comprend également des indicateurs d'énergie consommée (1) et des moyens d'introduction (4) et de visualisation (5) de données de telle sorte que l'utilisateur puisse contrôler la consommation accumulée, établir une valeur limite du coût d'énergie prévu, avertir lorsque la limite précitée est dépassée et éviter qu'un quelconque dispositif reste connecté après avoir quitté l'habitation, supprimant ainsi tout danger associé. Le dispositif de surveillance permet de mesurer différents points de l'installation et de réaliser des connexions/déconnexions automatiques de certaines charges afin d'éviter de créer des surtensions sur le réseau.
