METHOD AND SYSTEM FOR DETERMINING LOCATION OF HIGH-SPEED TRAIN IN NAVIGATION BLIND ZONE BASED ON METEOROLOGICAL PARAMETERS Russian patent published in 2023 - IPC B61L25/02 G06V30/19 

FIELD: railway transport.

SUBSTANCE: facilities for determining the location of trains in tunnels using meteorological parameters. The system contains sensors installed at the entrance to the tunnel to obtain meteorological parameters in the tunnel, a meteorological map generator, a control panel, a communication channel with the on-board security system of the locomotive. In this case, the sensors are made in the form of a radio meteorological complex, including a meteorological radar station, a microwave radiometer, a radial Doppler velocity detector at different antenna elevation angles, a radial wind velocity spectrum width detector, the sensors are connected to computer equipment via a pantograph - contact network communication line.

EFFECT: ability to determine the location of the train.
