Abstract

Cette invention se rapporte à un procédé et à un système de transmission de données à utiliser par exemple dans une mine. Les données entre une station de surveillance (10 à 12) et une machine de travail (19) sont transmises en mode numérique par un protocole de transmission de données déterministe, au moyen duquel une ou plusieurs machines de travail (19) peuvent être commandées à distance essentiellement en temps réel, et dans lequel le délai de transmission des données est compris dans des limites prédéterminées.
