Abstract

Clef électronique pour déverrouiller une serrure électronique Cette clef électronique comporte : - une mémoire (68) comportant : - une table (82) pré-enregistrée de consommation, cette table associant une quantité prédéterminée d'énergie consommée à chaque fonction préprogrammée exécutable par un microprocesseur (66) de la clef, et - une quantité d'énergie restante stockée dans la pile, - le microprocesseur (66) est programmé pour, a chaque exécution d'une des fonctions préprogrammées, : - estimer une nouvelle quantité d'énergie restante en décrémentant la quantité d'énergie restante précédemment enregistrée dans la mémoire d'une valeur qui est construite à partir de la quantité d'énergie consommée qui est associée à cette fonction préprogrammée par la table de consommation, puis - enregistrer dans la mémoire la nouvelle quantité d'énergie restante à la place de la précédente quantité d'énergie restante. Fig. 2Electronic key for unlocking an electronic lock This electronic key comprises: - a memory (68) comprising: - a pre-recorded table (82) of consumption, this table associating a predetermined quantity of energy consumed with each pre-programmed function executable by a microprocessor (66) of the key, and - a quantity of remaining energy stored in the battery, - the microprocessor (66) is programmed to, each time one of the preprogrammed functions is executed, - estimate a new quantity of remaining energy by decrementing the amount of remaining energy previously stored in the memory by a value which is constructed from the amount of energy consumed which is associated with this function pre-programmed by the consumption table, then - storing in the memory the new amount of energy remaining instead of the previous amount of energy remaining.
