Apparatus and method for precisely locating a railway carriage along a railway track equipped with balises and antenna intended to equip such a device

摘要

The localization detector for a train on a railway track uses beacons (2) to transmit an electromagnetic signal to the vehicle antenna (1) and receive. Each beacon has an emission circuit with a loop. the train antenna has a secondary receiver circuit with a figure of eight loop to allow the precise determination of when the antenna is opposite the beacon. The exterior width of the secondary loop matches that of the beacon loop. Claims include a method and antenna for the detector.
