Patent

CA 2692300

The invention relates to a method of managing an electrical power supply outage on board an aircraft, comprising the following operations: - detection of an electrical power supply outage, - measurement of a duration of the power supply outage by measuring a discharge time of a capacitor (41) and comparing this measured duration with a threshold duration, - saving a long outage indication when the duration of the outage is greater than a threshold duration. The invention also relates to a system implementing this method and comprising: - a circuit (2) for detecting an electrical power supply outage, - a circuit (4) for measuring a duration of the power supply outage, and - a circuit (3) for managing indications able to manage emissions of signals according to the measured duration of the power supply outage.

L'invention concerne un procédé de gestion d'une coupure d'alimentation électrique à bord d'un aéronef, comportant les opérations suivantes : - détection d'une coupure d'alimentation électrique, - mesure d'une durée de la coupure d'alimentation par mesure d'un temps de décharge d'un condensateur (41) et comparaison de cette durée mesurée avec une durée seuil, - sauvegarde d'une information de coupure longue lorsque la durée de la coupure est supérieure à une durée seuil L'invention concerne également un système mettant en oeuvre ce procédé et comportant : - un circuit de détection (2) d'une coupure d'alimentation électrique, - un circuit de mesure (4) d'une durée de la coupure d'alimentation, et - un circuit de gestion (3) d'informations apte à gérer des émissions de signaux en fonction de la durée mesurée de la coupure d'alimentation.
