Title (EN) RAILWAY WHEEL SENSOR EMPLOYING HALL EFFECT DEVICES
(FR) CAPTEUR DE ROUES FERROVIAIRES
Abstract: front page image
(EN)A sensor for detecting the presence of wheels of a rail vehicle is disclosed. The sensor comprises first and second Hall Effect devices, a magnet for supplying a magnetic field to the first and second Hall Effect devices, means for mounting the first and second Hall Effect devices and the magnet adjacent to the rail, whereby a railway vehicle wheel changes the magnetic field in the Hall Effect devices to produce wheel indication signals, and a processing circuit for receiving the wheel indication signals from the first and second Hall Effect devices and for producing an output signal in response to the wheel indication signals. A method of detecting the presence of a wheel is also provided.
(FR)La présente invention concerne un capteur destiné à détecter la présence de roues d'un véhicule ferroviaire. Ce capteur comprend un premier et un second dispositif à effet Hall, un aimant permettant de fournir un champ magnétique au premier et au second dispositif à effet Hall, un organe permettant de monter le premier et le second dispositif à effet Hall et l'aimant à côté du rail, une roue de véhicule ferroviaire modifiant le champ magnétique dans les dispositifs à effets Hall de façon à produire des signaux indicateurs de roue et, un circuit de traitement destiné à recevoir ces signaux indicateurs de roue en provenance du premier et du second dispositif à effet Hall afin de produire un signal de sortie en réponse à ces signaux indicateurs de roue. Cette invention concerne aussi un procédé de détection de présence de roue.
