Abstract

Le système de l'invention connecte une pluralité de dispositifs électroniques/électriques installés dans divers espaces d'une zone domestique, au moyen d'un réseau sans fil, afin d'établir un réseau domestique, reconnaît l'instruction de commande du dispositif électronique/électrique par reconnaissance vocale, et commande le fonctionnement du dispositif électronique/électrique correspondant par communication de données sans fil. Un dispositif de commande d'un système de réseau domestique, dans un système de réseau domestique, conçu pour connecter un ou plusieurs dispositifs électroniques/électriques qui sont installés dans des espaces respectifs dans une zone domestique au moyen d'un réseau, comprend : un ou plusieurs moyens de reconnaissance vocale, installés dans la zone domestique, offrant une fonction de reconnaissance vocale et une fonction de télécommande, reconnaissant une instruction vocale d'un utilisateur, mettant en correspondance les ID de dispositifs électroniques/électriques cibles de commande désignés, et produisant en sortie des données de commande par communication RF; et un répéteur, connecté au dispositif électronique/électrique par un procédé prédéterminé, recevant les données de commande transmises par le moyen de reconnaissance vocale par communication RF, rétablissant les données de commande pour analyser les ID, déterminant s'il s'agit d'une instruction de performance demandant que répéteur d'effectuer une opération du dispositif électronique/électrique connecté, et transmettant un résultat de performance d'une opération de commande au moyen de reconnaissance vocale, par communication RF. Un réseau domestique est généré par connexion du moyen de reconnaissance vocale et du répéteur, et par connexion du répéteur par un canal de données radio.
