Abstract

L'invention concerne un système de surveillance d’état à capteur comprenant une alimentation électrique ; un capteur de surveillance d’état ; un processeur ; un temporisateur de mise sous tension à alimentation constante ; et une horloge de surveillance. Le temporisateur de mise sous tension à alimentation constante est réglé sur une première durée prédéterminée. Le temporisateur de mise sous tension à alimentation constante est configuré pour activer le processeur en connectant le processeur à l’alimentation électrique si le temporisateur de mise sous tension parvient à la fin de sa durée. Lors de son activation, le processeur est configuré pour réinitialiser le temporisateur de mise sous tension à la première durée prédéterminée. Lors de son activation, le processeur est configuré pour commander au moins le capteur de surveillance d’état. Le capteur de surveillance d’état peut recueillir des données de surveillance d’état. Lors de son activation, le processeur est configuré pour régler l’horloge de surveillance sur une seconde durée prédéterminée. L’horloge de surveillance est alimentée par le biais de l’alimentation électrique. L’horloge de surveillance force le processeur et l’horloge de surveillance à entrer en mode d’inactivité en déconnectant le processeur et l’horloge de surveillance de l’alimentation électrique si l’horloge de surveillance parvient à la fin de sa durée.
