METHOD OF INFORMATION EXCHANGE BETWEEN ELECTRIC CENTRALIZATION STATIONS AND LINE POINTS Russian patent published in 2018 - IPC B61L23/16 

FIELD: traffic control systems.

SUBSTANCE: invention relates to railway automation and telemechanics. In the method, the time interval allocated for the exchange of information is generated by consisting of three pulses, first of which is sent from the central station to ensure the switching on / off of the line point (LP), the second is for the transmission from the LP of the information on the track section state, third is for reading from the central station of the combination mark on the number of free track sections, as well as the code combination about the reception track number on the LP. At that, both code combinations are transmitted during time intervals, another time interval is used to change the direction of travel, wherein the direction change is carried out after the transmission of the three signals in the adjacent code cycles, the first as the request signal, the second as the acknowledgment signal, third as the end of direction change signal, the next time interval is provided for the cycles synchronization signal, which is transmitted by the station set to receive the train.

EFFECT: enabling increase in the trains traffic control reliability.
