METHOD OF AUTOMATIC CROSSING SIGNALING SYSTEM MANAGEMENT Russian patent published in 2017 - IPC B61L29/22 

FIELD: electricity.

SUBSTANCE: AC signal is continuously applied to the rail-track line feed end and the amplitude of the voltage and current is continuously measured at the same end with different values of the coordinate of the train shunt location from the relay to the feed end of the rail-track line and a plurality of measured values of voltage, current and corresponding coordinates of the train location is formed, with the help of which a system of equations is compiled. Coefficients of the train coordinate equation are determined, the current coordinate of the train location in the approach segment is determined measuring the current value of voltage and current, the train speed in the segment is determined, and the actual coordinate of the crossing shuttering is determined taking into account possible acceleration of the train. Moreover, at the moment of the train enter into the approach segment, the current coordinate of the train location, determined by the equation, is compared with the length of the approach segment, the coefficients of the train coordinate equation are corrected in case of inequalities of those values, and the train speed and the actual coordinate of the crossing shuttering are determines in case of the value equality.

EFFECT: increased traffic safety.
