Abstract

La présente invention concerne un dispositif de surveillance 3 qui comprend une unité d'entrée 31 et une unité de stockage 34. Des signaux de détection provenant d'un capteur S, qui détecte l'état d'alimentation électrique d'un câble d'alimentation électrique C qui fournit de l'énergie à un outil T, sont entrés dans l'unité d'entrée 31. Les signaux de détection entrés dans l'unité d'entrée 31 sont stockés par ordre chronologique dans l'unité de stockage 34 en tant qu'indicateur de l'état de travail d'un travailleur utilisant l'outil T.
