Abstract

L'invention concerne une structure d'émission infrarouge (11), une télécommande infrarouge, et un procédé de télécommande infrarouge. La structure d'émission infrarouge (11) comprend : de multiples émetteurs infrarouges (111), placés à de multiples positions d'une télécommande infrarouge et configurés pour émettre de manière cyclique un code infrarouge selon une séquence prédéterminée ; un système de commande (112), situé à l'intérieur de la télécommande infrarouge, connecté aux multiples émetteurs infrarouges (111), et configuré pour commander les multiples émetteurs infrarouges (111) pour qu'ils émettent de manière cyclique le code infrarouge ; et un module de rétroaction (113), connecté au système commande (112), et configuré pour acquérir des informations de rétroaction de commande auprès d'un appareil commandé de la télécommande infrarouge et envoyer les informations de rétroaction de commande au système de commande (112), de sorte que le système de commande (112) commande les multiples émetteurs infrarouges (111) pour qu'ils arrêtent l'émission cyclique du code infrarouge en fonction des informations de rétroaction de commande. La solution technique ci-dessus permet d'obtenir une commande de fonctionnement multidirectionnelle d'une télécommande infrarouge, réduit la puissance instantanée d'émission de code de la télécommande infrarouge, réduit la consommation d'énergie, évite des réponses répétées d'un équipement électrique lors de la réception répétée d'informations de commande, et augmente l'utilité de la télécommande infrarouge.
