Abstract

L'invention concerne un système de surveillance des incendies de forêt assurant une alimentation électrique via une production électrique hybride, ainsi qu'un procédé de surveillance des incendies de forêt. Un dispositif de relais du système de surveillance des incendies de forêt comprend : un nœud collecteur servant à recueillir des informations de détection nécessaires pour la surveillance des incendies de forêt à partir d'une pluralité de nœuds capteurs sans fil ; un dispositif émetteur-récepteur servant à envoyer les informations de détection recueillies au niveau du nœud collecteur à un centre de commande ; et une unité d'alimentation électrique servant à produire de l'électricité en combinant différentes quantités d'électricité produites et à fournir l'électricité produite au nœud collecteur et au dispositif émetteur-récepteur. En conséquence, du fait de la production électrique hybride, il devient possible d'alimenter en électricité le système de surveillance des incendies de forêt en utilisant un autre générateur lorsqu'un générateur tombe en panne, de sorte qu'une alimentation électrique stable du système de surveillance des incendies de forêt peut être réalisée et qu'un accroissement des coûts des lignes de transport d'électricité et de la détérioration du paysage peut être empêché.
