METHOD FOR TRANSMITTING INFORMATION ABOUT THE STATE OF RAIL CIRCUITS TO HIGH-SPEED TRAINS Russian patent published in 2022 - IPC B61L23/16 

FIELD: rail traffic management.

SUBSTANCE: invention relates to methods for transmitting information about the state of wayside circuits to high-speed trains using overhead lines. In the method, information is transmitted to high-speed trains overhead lines; along the route of the high-speed train with an interval of 45-55 km, linear control field stations are installed with traction substations, the overhead lines from which are suspended to the middle of the section between the linear control field station, with the participation of these overheads, information is transmitted to the high-speed train, to each high-speed train located in the approach control zone to the linear control field station or the departure control zone from the linear control field station, information about the condition of rail chains is transmitted to this and the next control zone; the LP and LC lines are laid from the middle of the section between the linear control field station to the linear control field station itself, i.e. in the approach and departure control zones, the same information is transmitted to all high-speed trains located in the same zone, and the train computer selects from it only the necessary information for this high-speed train; information is transmitted from the linear control field station to the high-speed train using a two-wire communication line, one wire of which is the contact lead between the high-speed train and the traction substation, and the other is the rails between the high-speed train and the suction feeder; the suction feeder circuit includes one winding of a stationary transformer, the second winding of which is connected by a two-wire line to a stationary filter, the first output of the stationary filter is connected by a two-wire line to the input of the receiver of the odd path, the output of which is with the first input of the computer, the second output of the stationary filter is connected by a two-wire line to the input of the receiver of the even path, the output of which is with the second train computer input; on the high-speed train, the first winding of the traction substation train transformer is included in the circuit between the pantograph and the traction engines, the second winding of which is connected through the train filter to the input of the train receiver, the output of which is connected to the train computer.

EFFECT: reliability of transmission is improved and the possibility of regulating the movement of high-speed trains in shallow tunnels is achieved.
