si l'ordre de commande comprend des informations d'augmentation de la quantité de chemins de transmission de données entre le réseau de microphones sans fil et l'hôte, la transmission, par le réseau de microphones sans fil, sur un chemin de transmission de données qui est disponible après l'augmentation, de données à l'hôte selon les informations d'augmentation de la quantité de chemins de transmission de données.
une unité d'acquisition de paramètres (10), configurée pour acquérir des informations de paramètre de canaux de communication sans fil entre un réseau de microphones sans fil et l'hôte ;
une première unité de traitement (11), configurée pour: si les informations de paramètre acquises par l'unité d'acquisition de paramètres (10) satisfont une première condition préréglée, déterminer des informations de réduction de la fréquence d'échantillonnage du réseau de microphones sans fil, et si la fréquence d'échantillonnage réduite selon les informations de réduction est inférieure ou égale à une fréquence minimale préréglée, déterminer des informations de diminution d'une quantité de chemins de transmission de données entre le réseau de microphones sans fil et l'hôte ; et
une unité d'envoi d'ordre (12), configurée pour : si la première unité de traitement (11) détermine les informations de réduction de la fréquence d'échantillonnage, envoyer un ordre de commande au réseau de microphones sans fil, l'ordre de commande comprenant les informations de réduction de la fréquence d'échantillonnage; et si la première unité de traitement (11) détermine les informations de diminution de la quantité de chemins de transmission de données, envoyer un ordre de commande au réseau de microphones sans fil, l'ordre de commande comprenant les informations de réduction de la fréquence d'échantillonnage, et comprenant en outre les informations de diminution de la quantité de chemins de transmission de données.
une deuxième unité de traitement (13), configurée pour : si les informations de paramètre acquises par l'unité d'acquisition de paramètres (10) satisfont une deuxième condition préréglée, déterminer des informations d'augmentation de la fréquence d'échantillonnage du réseau de microphones sans fil ; dans lequel
l'unité d'envoi d'ordre (12) est en outre configurée pour : si la deuxième unité de traitement (13) détermine les informations d'augmentation de la fréquence d'échantillonnage, envoyer un ordre de commande au réseau de microphones sans fil, l'ordre de commande comprenant les informations d'augmentation de la fréquence d'échantillonnage.
une unité de réception d'ordre (30), configurée pour recevoir un ordre de commande envoyé par l'hôte selon des informations de paramètre de canaux de communication sans fil entre le réseau de microphones sans fil et l'hôte après que l'hôte a acquis les informations de paramètre ;
une unité d'échantillonnage (31), configurée pour : si les informations de paramètre satisfont une première condition préréglée, et l'ordre de commande reçu par l'unité de réception d'ordre (30) comprend des informations de réduction de la fréquence d'échantillonnage du réseau de microphones sans fil, échantillonner, par le réseau de microphones sans fil, des données collectées à la fréquence d'échantillonnage réduite selon les informations de réduction ; et
une unité de transmission de données (32), configurée pour : si la fréquence d'échantillonnage réduite est inférieure ou égale à une fréquence minimale préréglée, et l'ordre de commande reçu par l'unité de réception d'ordre (30) comprend en outre des informations de diminution d'une quantité de chemins de transmission de données entre le réseau de microphones sans fil et l'hôte, transmettre, par le réseau de microphones sans fil, sur un chemin de transmission de données qui est disponible après la diminution, des données à l'hôte selon les informations de diminution.
