Patent

CA 2587440

Low-cost intelligent control and communication devices (21, 22, 23, 51, 52) are arranged to communicate with one another over one or more shared physical media (10, 11), such as a powerline or a radio frequency band. No network controller is needed, because any device can act as a master, slave or repeater. Adding more devices makes the system more robust, by virtue of a simple protocol (30, 50, 60) for communication retransmissions and retries.

L'invention concerne des dispositifs (21, 22, 23, 51, 52) de commande et de communication intelligents, peu onéreux, disposés de manière à communiquer mutuellement par l'intermédiaire d'un ou de plusieurs moyens physiques (10, 11) communs, tels qu'une ligne électrique ou une bande de fréquences radioélectriques. Aucun contrôleur de réseau n'est nécessaire, car chaque dispositif peut agir comme maître, esclave ou répéteur. L'addition de dispositifs supplémentaires permet de rendre le système plus robuste, grâce à un simple protocole (30, 50, 60) de retransmission et de réessai de communication.
