If the number of thermistors is three or more, for example, the temperature difference is calculated by round robin for the combination of two thermistors, and if even one temperature difference is larger than the first temperature, it is determined that an abnormality in the thermistor has been detected. The heating of the capsules may then be stopped.

Abstract

Le présent dispositif de génération d'aérosol a une première partie de chauffage qui chauffe une première source d'aérosol qui est un liquide, une seconde partie de chauffage qui chauffe une seconde source d'aérosol qui est un solide, une pluralité de capteurs de température qui mesurent la température de la seconde partie de chauffage, et une partie de commande qui commande l'alimentation en énergie de la première partie de chauffage et de la seconde partie de chauffage. La partie de commande exécute un premier diagnostic concernant les états de la pluralité de capteurs de température sur la base de différences de température qui sont entre la pluralité de capteurs de température et mesurées lorsque l'apparition d'un événement prédéterminé a été détectée.
