This method comprises steps consisting in a) continuously feeding the electrical circuit (3A, 3B) with electrical current with the transmission device (9A, 9B) and monitoring the presence of a rolling stock (T) on the corresponding track section (1 A, 1 B) by measuring, using the reception device (11 A, 11 B), the current circulating in the electrical circuit (3A, 3B); b) if the reception device (11 A, 11 B) detects that a rolling stock (T) is present on the track section (1 A, 1 B), applying to the electrical circuit (3A, 3B) a nominal electrical power (PN) at least until the rolling stock (T) exits the section (1 A, 1 B); c) if the reception device (11 A, 11 B) detects that no rolling stock (T) is present on the track section (1A, 1 B), applying to the electrical circuit (3A, 3B) a power-saving power value (P0) which is inferior to the nominal power (PN).

    • The invention relates to a wheel sensor, in particular for a track clear detection unit, comprising two sensor channels (A, B) that work inductively and have a separate transmitter and receiver that are separated by a railway (1). The aim of the invention is to compensate interference voltages simply and effectively. To achieve this, a processing unit is provided to evaluate the level of received signals (8, 9) of the sensor channel (A or B) that is affected by the passing of a wheel and the other non-affected sensor channel (B or A). The processing unit has means for linking the received signals, (in particular by subtraction) (8, 9) of the non-affected and affected sensor channel (A, B).

    • Die Umgebung des Geleisekörpers (3) ist erheblichen elektromagnetischen Störbeeinflussungen durch z.B. Traktionsrückströme, Wirbelstrombremsen oder Magnetschienenbremsen ausgesetzt. Dadurch wird die Funktionstüchtigkeit von Geleisestromkreisen und von an einer Schiene (3) angebrachten magnetischen Raddetektoren (5, 9a, 9b; 9c, 9d) stark beeinträchtigen. Um diese Störbeeinflussungen in sicherheitsrelevanter Hinsicht unwirksam zu machen, wird vorgeschlagen, die vorgenannten Einrichtungen mit einem spektral breitbandigen Signal zu beaufschlagen. Besonders vorteilhaft sind dabei das Direct Sequence Spread Spectrum-Verfahren (DSSS) und das Frequency Sweep Keying-Verfahren (FSK). Durch eine Codierung können bestehende Gleisstromkreise oder Raddetektoren ohne zusätzliche Installation am Geleise (3) echt zweikanalig (5a, 5b; 5c, 5d; 6a, 6b; 6c, 6d) betrieben werden und dadurch hohe Sicherheitsanforderungen erfüllt werden.
