Abstract

An assembly with rail contacts actuated by vehicles to produce presence and/or direction criteria, running, with voltages that differ in magnitude as well as in phase, which are induced in receiver coils by means of magnetic fields generated by AC powered transmitter coils, located in the vicinity of the rails, as a function of the passage of the wheel through the magnetic fields, these voltages being processed by electronic evaluation means that give rise to presence criteria in relation to the passage of vehicles at a certain point in the track circuit, characterized in that in the magnetic field produced by a transmitting coil (eg, S, S1, Fig. 2, 4, 5) powered by alternating current, only one receiving coil (E, E1) is arranged) in such a way that in the condition in which there is no influence of the rail contact, substantially no voltage is induced in the receiving coil and because in re In response to the action of a vehicle passing through the area of action of the rail contact, a voltage is induced in the receiving coil, its phase position depending on the momentary position of the parts of the vehicle that influence the magnetic field in relation with the receiving coil.
