Abstract

Système de commande multi-sécurité électrique numérique empêchant l'apparition d'accidents électriques qui conduisent à, par exemple, l'apparition d'incendie dans un dispositif d'alimentation électrique qui est électriquement connecté par l'intermédiaire, par exemple, d'une unité électrique, telle qu'un tableau de commande, un tableau de distribution, un panneau d'éclairage, une carte d'alimentation, une carte de commande, et une boîte de jonction, dans laquelle un trajet électrique côté alimentation électrique provenant du côté alimentation électrique et un trajet électrique côté charge conduisant à une charge sont disposés dans le boîtier. Le système de commande multi-sécurité électrique numérique empêche en outre l'apparition d'accidents tels que des dommages sur divers dispositifs ou unités d'alimentation/électriques auxquels le trajet électrique côté charge est connecté. Le système de commande multi-sécurité électrique numérique est pourvu d'un moyen de commande de commutation d'alimentation électrique qui, lorsqu'un signal d'arrêt d'alimentation électrique est délivré à n'importe lequel de premiers dispositifs d'alimentation, délivre un signal de démarrage d'alimentation électrique à l'un quelconque des premiers dispositifs d'alimentation de façon à fournir de l'énergie, à la place du premier dispositif d'alimentation recevant l'entrée du signal d'arrêt d'alimentation électrique, à une charge recevant l'alimentation électrique provenant du premier dispositif d'alimentation recevant l'entrée du signal d'arrêt d'alimentation électrique.
