Abstract

L'invention concerne un procédé et un appareil de commande de fonctionnement de dispositif et concerne un appareil de traitement de vêtements. Le procédé consiste : à acquérir, au moyen d'un dispositif de commande d'un dispositif, un signal de détection d'anomalie collecté par un capteur de prévention de pincement de main ; à interroger un état de fonctionnement d'un organe de transmission dans le dispositif ; et à identifier, en fonction de l'état de fonctionnement de l'organe de transmission, que le signal de détection d'anomalie est une fausse alarme et à commander l'organe de transmission de sorte qu'il maintienne l'état de fonctionnement. En combinant le signal de détection d'anomalie détecté par le capteur avec l'état de fonctionnement de l'organe de transmission pour identifier si une anomalie est une fausse alarme, le cas d'une fausse alarme d'anomalie peut être filtré avec précision, de sorte à rendre la fiabilité relativement élevée. Le problème technique de l'état de la technique, d'une précision relativement faible résultant de la réalisation d'une détection et d'une identification d'anomalie uniquement au moyen d'un capteur, est résolu.
