Title (EN) DATA SENDING/RECEIVING METHOD AND DATA TRANSMISSION SYSTEM OVER SOUND WAVES
(FR) PROCÉDÉ D'ENVOI/DE RÉCEPTION DE DONNÉES ET SYSTÈME DE TRANSMISSION DE DONNÉES PAR ONDES SONORES
Abstract:
(EN) A sound wave-based data sending method, apparatus, and electronic device, a sound wave-based data receiving method, apparatus, and electronic device, and a sound wave-based data transmission system. The sound wave-based data sending method includes: obtaining to-be-sent data; obtaining a sound wave frequency sequence corresponding to the to-be-sent data according to a preset sound wave frequency mapping table; generating a filtered sound wave signal sequence according to the sound wave frequency sequence and a preset sending duration, the sending duration being sending duration of a sound wave signal corresponding to a single character; and sending a sound wave signal corresponding to the to-be-sent data according to the filtered sound wave signal sequence. The method, apparatus, and electronic device of the present application provide an improved communication distance and identification accuracy.
(FR) L'invention concerne un procédé, un appareil et un dispositif électronique d'envoi de données à base d'ondes sonores, un procédé, un appareil et un dispositif électronique de réception de données à base d'ondes sonores, et un système de transmission de données à base d'ondes sonores. Le procédé d'envoi de données à base d'ondes sonores comprend les étapes suivantes : obtenir des données à envoyer ; obtenir une séquence de fréquences d'onde sonore correspondant aux données à envoyer selon une table de mappage de fréquences d'onde sonore prédéfinie ; produire une séquence de signaux d'onde sonore filtrés selon la séquence de fréquences d'onde sonore et une durée d'envoi prédéfinie, la durée d'envoi étant la durée d'envoi d'un signal d'onde sonore correspondant à un caractère unique ; et envoyer un signal d'onde sonore correspondant aux données à envoyer selon la séquence de signaux d'onde sonore filtrés. Le procédé, l'appareil et le dispositif électronique de la présente invention offrent une distance de communication et une précision d'identification améliorées.
