Abstract

L'invention concerne un procédé de commande d'unité intérieure de climatiseur et un dispositif de commande, le procédé de commande consistant à : extraire d'un son acquis par l'unité intérieure de climatiseur un signal vocal cible envoyé par un utilisateur cible ; extraire des informations de caractéristiques du signal vocal cible et reconnaître un état pharyngé de l'utilisateur cible selon les informations de caractéristiques ; lorsqu'il est déterminé que l'état pharyngé indique une gêne de l'utilisateur cible, acquérir une stratégie auxiliaire de traitement et de guérison préconfigurée pour le climatiseur ; et commander le fonctionnement de l'unité intérieure de climatiseur selon la stratégie auxiliaire correspondante de traitement et de guérison. La solution technique proposée par la présente divulgation ne reconnaît pas seulement l'état pharyngé de l'utilisateur cible au moyen de l'unité intérieure de climatiseur, mais commande également le fonctionnement de l'unité intérieure de climatiseur selon la stratégie auxiliaire correspondante de traitement et de guérison pour atténuer autant que possible la gêne de l'utilisateur cible lorsqu'il est déterminé que l'état pharyngé indique une gêne de l'utilisateur cible. L'expérience de l'utilisateur et le niveau d'intelligence du climatiseur intelligent sont améliorés.
