Abstract

L'invention concerne un système d'automatisation sans fil comprenant un appareil et un procédé permettant de transférer des données entre une pluralité d'équipements ou d'appareils électriques (serveurs). Selon un mode préféré de réalisation, plusieurs serveurs, y compris ceux présentant une télécommande à infrarouges, maintiennent des liaisons de communication sans fil avec au moins une station de commande pour la transmission et la réception de données. Ces serveurs sont couplés électriquement ou optiquement aux équipements ou appareils électriques. Des blocs de données présentant une identification de dispositif unique sont codés au moyen de la technique de codage par décalage de fréquence avant d'être envoyés à l'émetteur-récepteur de fréquence pour être modulés en signaux FM. La station de commande comporte un processeur central qui convertit les données numériques provenant de l'émetteur-récepteur en impulsions carrées de fréquence correspondante avant de les transmettre à l'émetteur-récepteur RF des serveurs. Le système de la présente invention transmet et reçoit les blocs de données entre une station de commande et plusieurs serveurs de façon sûre en utilisant la même fréquence radio sans affecter la fiabilité du système.
