Abstract

L'invention concerne un système de surveillance pour un transport sur rails de marchandises ou de passagers dans au moins un wagon. Le ou les wagons selon l'invention peuvent par exemple être des wagons de chemin de fer ou de tramway employés dans le réseau ferroviaire public. Le système de surveillance comporte en premier lieu un palier de générateur intégré à au moins un palier de roue du wagon. Le palier de générateur sert ainsi au logement d'une roue du wagon d'une part, et à la production d'énergie électrique d'autre part, de manière à former une unité d'alimentation en énergie. Dans le palier de générateur, les composants nécessaires à la production d'une tension électrique sont intégrés au palier. Un de ces composants est formé par un dispositif conducteur pour l'induction d'une tension électrique à produire. Le système de surveillance comporte par ailleurs une électronique de détection reliée électriquement au dispositif conducteur pour déterminer des grandeurs de mesure agissant sur le dispositif conducteur. Par conséquent, le palier de générateur constitue un détecteur.
