Qu'est-ce que le semi-duplex ?

Duplex intégral désigner une méthode de transmission dans laquelle les deux parties communicantes peuvent effectuer des opérations d'envoi et de réception en même temps lorsque l'envoi et la réception de données sont séparées et transmises par deux lignes de transmission différentes. En mode duplex intégral, chaque extrémité du système de communication est équipée d'un émetteur et d'un récepteur, de sorte que les données peuvent être contrôlées pour être transmises dans les deux sens en même temps. Le mode duplex intégral ne nécessite pas de changement de direction, il n'y a donc pas de retard causé par les opérations de commutation, ce qui est très avantageux pour les applications interactives qui ne peuvent pas avoir de retards (comme les systèmes de surveillance et de contrôle à distance). Par exemple, parmi les produits de communication, les talkies-walkies sont un exemple typique de semi-duplex ; les téléphones sont une application duplex intégrale.


Bien que le duplex intégral soit pratique, puisqu'il envoie et reçoit la voix en même temps, il entraînera inévitablement un gros problème : l'écho. Comme les deux côtés de l'interphone bidirectionnel parlent en même temps, la voix de l'autre partie est transmise au microphone via le haut-parleur, ce qui provoque une diaphonie d'écho, qui affecte les appels normaux. Par conséquent, si vous souhaitez réaliser la fonction d'interphone vocal en duplex intégral, vous devez d'abord résoudre le problème de l'élimination de l'écho.
