Title
(EN) HIGHWAY-RAIL GRADE CROSSING HAZARD MITIGATION
(FR) ATTENUATION DU DANGER AUX INTERSECTIONS AUTOROUTE-VOIE FERREE
Abstract
(EN)
A hazard mitigation system (10) to detect an object (22) in a highway-railway grade crossing (12). A structure is provided that includes a fixed foundation (18b) and a surface layer (18a) that is cushionably placed above the foundation, such that the structure is located between tracks (16) at the crossing. At least one sensor (20) is mounted between the surface layer and the foundation. This sensor senses the weight of the object upon the surface layer and provides a sensor signal representative of that weight. A control unit (502) receives the sensor signal, processes it to determine whether the object represents a potential hazard, and, if so generates a warning signal. The sensor can particularly include a pressure gage (20a) or strain gage (20b), or a fiber optic sensor (20c). When a fiber optic sensor is employed, it can particularly include a fiber Bragg grating (100).
(FR)
L'invention concerne un système d'atténuation du danger (10) servant à détecter un objet (22) à une intersection autoroute-voie ferrée (12). Une structure est mise en oeuvre, qui comprend une fondation à demeure (18b) et une couche superficielle (18a) disposée au-dessus de la fondation pour amortir les chocs, si bien que la structure se situe entre des voies (16), au niveau de l'intersection. Au moins un capteur (20) est installé entre la couche superficielle et la fondation. Le capteur détecte le poids de l'objet présent sur la couche superficielle et émet un signal de détection représentant ce poids. Une unité de commande (502) reçoit le signal de détection, le traite et détermine si l'objet représente un danger potentiel et, si c'est le cas, émet un signal d'alarme. Le capteur peut comprend notamment un manomètre (20a), ou une jauge dynamométrique (20b), ou un détecteur à fibre optique (20c). Lorsqu'un détecteur à fibres optiques est utilisé, il peut comprendre en particulier un réseau de Bragg à fibres (100).
