METHOD OF CLOSING RAILWAY CROSSINGS Russian patent published in 2017 - IPC B61L29/00 B61L29/18 

FIELD: electricity.

SUBSTANCE: parameters, obtained in the method of the analog track circuit comprising reading voltage U and current I at the feed end of the rail line; the reference parameters of the delay time of closing the move are determined, based on the processing of the primary parameters; store in memory of mentioned reference parameters; determine the change in the parameters of the selected control area, which is carried out for the selection of characteristic features, describing the state of the rail line; determine the position, direction and speed of the rolling stock. Then the secondary parameters containing data is formed on the calculated actual speed and direction of the rolling stock on the control section of the rail line; the comparison of the secondary parameters with reference parameters for the selected area are carried out. And on the basis of comparison, the value of the coordinates of the closure of the move, and on the basis of the received coordinates of the activation automatic means crossing signaling is carried out.

EFFECT: improving of the accuracy of determining the time of the train approaching the crossing.
