Abstract | A battery operated device such as a road stud comprises a micro-controller, a battery, and a light source. The micro-controller is configured to operate the battery to provide a train of power pulses to the light source, and each power pulse has a characteristic pulse period and a characteristic duty cycle comprising an on-cycle and an off-cycle. The micro-controller is turned on during the on-cycle and turned into a power saving or sleep mode during the off cycle. Setting the micro-controller into the power saving or sleep mode during the off cycle of the power pulse means substantial battery power saved to extend the operation time per charging of the battery.
L'invention concerne un dispositif fonctionnant sur batterie, tel qu'un plot routier comportant un microcontrôleur, une batterie et une source lumineuse; le microcontrôleur étant configuré pour exploiter la batterie afin d'envoyer un train d'impulsions de puissance à la source lumineuse, et chaque impulsion de puissance présentant une période d'impulsion caractéristique et un cycle de service caractéristique comportant un cycle de marche et un cycle d'arrêt. Le microcontrôleur est en marche pendant le cycle de marche et placé en mode d'économie d'énergie ou de sommeil pendant le cycle d'arrêt. Le fait de placer le MCU en mode de sommeil pendant le cycle d'arrêt de l'impulsion de puissance se traduit par une économie substantielle d'énergie de la batterie en vue de prolonger la durée de fonctionnement pour chaque charge de la batterie. |
