Title
(EN) RAILROAD TRAFFIC WARNING SYSTEM APPARATUS AND METHOD THEREFOR
(FR) SYSTEME D'ALARME DE TRAFIC FERROVIAIRE ET PROCEDE CORRESPONDANT
Abstract
(EN)
A railroad traffic warning system for alerting a motorist or a maintenance-of-way crew of an approaching train. The system has magnetometer sensor probes (50) along the right-of-way adjacent to a railroad track. These sensor probes (50) provide a signal to a controller unit (32) when the presence of a train is sensed. The system may be powered by a battery, which may be recharged by a solar panel array (40).
(FR)
Cette invention concerne un système d'alarme de trafic ferroviaire permettant d'avertir un automobiliste ou un agent de maintenance des voies de l'approche d'un train. Ledit système comporte des sondes (50) de détection magnétométriques disposées le long de l'emprise du chemin de fer jouxtant une voie de chemin de fer. Ces sondes (50) de détection délivrent un signal à une unité de commande (32) dès que la présence d'un train est détectée. Ledit système peut être alimenté par une batterie qui peut être rechargée au moyen d'un panneau solaire (40).
