Abstract

La présente divulgation concerne un serveur, un dispositif intelligent et un procédé de commande de dispositif intelligent. Un serveur peut acquérir des informations de dispositif régional, les informations de dispositif régional comprenant plusieurs premières régions et des informations de dispositif pour des dispositifs intelligents dans les premières régions. Le serveur acquiert des dispositifs de commande principaux dans les premières régions selon les informations de dispositif, et signale les dispositifs de commande principaux. Chaque dispositif de commande principal envoie au serveur une demande de réponse à une instruction après la détection d'une instruction vocale d'un utilisateur, et le serveur peut acquérir un dispositif de commande principal cible et une première région cible correspondant au dispositif de commande principal cible. Sur la base de la première région cible et du dispositif de commande principal cible, le serveur détermine un dispositif intelligent à commander et envoie une instruction de réponse au dispositif intelligent à commander. Le dispositif intelligent à commander peut exécuter l'instruction de réponse de façon à obtenir des exigences d'utilisateur. Par conséquent, le procédé évite de demander à un utilisateur le dispositif qui est en marche, ce qui permet d'améliorer la convivialité d'utilisation pour l'utilisateur.
