Abstract

L'invention concerne un procédé de détection et de commande d'alimentation électrique sans fil, ainsi qu'un système correspondant. Le procédé de détection et de commande d'alimentation électrique sans fil comprend les étapes suivantes. Un dispositif électronique (40) reçoit une alimentation électrique sans fil d'un dispositif extérieur (20) d'émission d'énergie électrique sans fil et effectue une conversion de paramètres électriques sur l'alimentation électrique reçue sans fil pour obtenir une tension d'entrée continue qui est la tension de la source d'alimentation. Une valeur d'amplitude de la tension d'entrée continue est détectée. La tension d'entrée continue ainsi détectée est comparée à une plage de tension de référence et un résultat de comparaison est produit. Si le résultat de la comparaison indique que la tension d'entrée continue ainsi détectée dépasse la plage de tension de référence, un message d'informations est affiché sur un module d'affichage (17) jusqu'à ce que la tension d'entrée continue détectée soit dans la plage de tension de référence. La tension de la source d'alimentation du dispositif électronique peut être maintenue dans une plage de fonctionnement normal par détection de la valeur d'amplitude de la tension d'entrée continue, affichage d'un message d'informations en fonction d'un résultat de détection et réalisation de la régulation correspondante. L'invention favorise un fonctionnement normal du dispositif électronique.
