Abstract

La présente invention concerne un système de gestion de sécurité comprenant un capteur pour vérifier la fixation d'un crochet de sécurité pour un travail en hauteur, ce système comprenant : une première unité dans laquelle un capteur détermine, lorsqu'un ouvrier accède à un chantier en hauteur, si le crochet de sécurité est fixé à une corde ou à un câble de sécurité, de façon à avertir l'ouvrier ou à transmettre, par l'intermédiaire d'une communication à courte distance ou longue distance, des informations concernant l'emplacement actuel de l'ouvrier et des informations indiquant si le crochet de sécurité est fixé ; une deuxième unité disposée au niveau du chantier en hauteur de façon à communiquer avec la première unité ; et une troisième unité pouvant établir une communication à courte distance ou longue distance avec la première unité et la deuxième unité. La présente invention permet d'identifier automatiquement, en temps réel, par l'intermédiaire du capteur, si l'ouvrier se trouvant sur le chantier en hauteur a fixé le crochet de sécurité d'une ceinture de sécurité à la corde ou au câble de sécurité antichute, de manière à fournir un avertissement si le crochet de sécurité n'est pas fixé et, simultanément, transmettre à un chef, par l'intermédiaire d'une communication sans fil, une information indiquant si le crochet de sécurité n'est pas fixé et effectuer un contrôle correspondant.
