Abstract

Il s'agit essentiellement de détecter la coupure de certains consommateurs électriques 2 montés en série avec une source de courant continu 4 et avec un interrupteur 3. Une résistance 1 de valeur très supérieure à celle du consommateur est montée en parallèle sur l'interrupteur et des moyens sont prévus pour exploiter la tension V1 recueillie aux bornes de cette résistance 1 lorsque l'interrupteur est ouvert, de brèves incursions en cette position ouverte étant prévues aux mêmes fins lorsque l'interrupteur est fermé, lesdites incursions étant déterminées par de brèves impulsions d'horloge propres actionner l'interrupteur alors constitué par un transistor. Application préférée : détection des ruptures de filaments des feux de position, feux de freinage ou phares équipant les véhicules, même en dehors des périodes d'utilisation de ces accessoires.This essentially involves detecting the cut-off of certain electrical consumers 2 connected in series with a direct current source 4 and with a switch 3. A resistor 1 of much greater value than that of the consumer is mounted in parallel on the switch and means are provided to exploit the voltage V1 collected at the terminals of this resistor 1 when the switch is open, brief incursions in this open position being provided for the same purposes when the switch is closed, said incursions being determined by brief pulses own clock actuate the switch then formed by a transistor. Preferred application: detection of filament breaks in position lights, brake lights or headlights fitted to vehicles, even when these accessories are not used.
