Abstract

Procédé de surveillance de la vitesse dans un système automatisé (4) pour un dispositif d'extraction (2), en particulier une installation d'extraction par puits, selon lequel des éléments de détection situés le long du parcours en vue de la détermination de la position sont superflus. Selon la présente invention, une valeur effective de parcours (Xa) et une valeur effective de vitesse (va) sont déterminées à l'aide d'au moins un compteur d'impulsions (18, 20, 22). Une valeur limite de vitesse (v2) est extraite à l'aide de la valeur effective de parcours (Xa) à partir d'une table de données enregistrée dans le système automatisé (4) et représentant une courbe de valeurs limites étagée (46) et la valeur effective de la vitesse (va) est comparée à la valeur limite de vitesse extraite (v2).
