Abstract

Ce système de traitement de vêtements comprend : un premier dispositif de traitement de vêtements comprenant un premier tambour, une première unité de commande pour commander le fonctionnement du premier tambour, et un port de diagnostic pouvant être connecté à un terminal de diagnostic ; et un second dispositif de traitement de vêtements comprenant un second tambour et une seconde unité de commande pour commander le fonctionnement du second tambour. La première unité de commande : comprend une première extrémité de transmission et une première extrémité de réception ; reçoit un premier signal de demande de diagnostic en provenance du port de diagnostic par l'intermédiaire de la première extrémité de réception ; identifie une cible de diagnostic sur la base du premier signal de demande de diagnostic ; effectue une opération de diagnostic correspondant au premier signal de demande de diagnostic en réponse à l'identification de la cible de diagnostic en tant que premier dispositif de traitement de vêtements, et puis transmet un premier signal de résultat de diagnostic au port de diagnostic par l'intermédiaire de la première extrémité de transmission ; et délivre un second signal de demande de diagnostic à la seconde unité de commande par l'intermédiaire de la première extrémité de transmission en réponse à l'identification de la cible de diagnostic en tant que second dispositif de traitement de vêtements.
