Abstract

L'invention concerne un dispositif pour le contrôle d'espaces dangereux. Dans ce dispositif pour le contrôle d'un espace dangereux G situé entre des barrières S1 à S4, il est prévu des émetteurs S* et des récepteurs E de rayonnement formés par les extrémités de sortie ou d'entrée d'un grand nombre de faisceaux LS, LE de guides de lumière raccordés à un émetteur commun S ou à un circuit d'exploitation A, les extrémités d'entrée et de sortie des faisceaux de guides de lumière étant disposées le long de la limite de l'espace dangereux et étant alignées optiquement sur les émetteurs ou récepteurs associés. Application notamment aux passages à niveau de voies ferrees.
