DEVICE FOR CHECKING AUTOMATIC LOCOMOTIVE ALARM WITH INDUCTIVE CHANNEL FOR TRANSMITTING INFORMATION Russian patent published in 2020 - IPC B61L3/08 

FIELD: physics; transnational transportation.

SUBSTANCE: invention relates to a device for checking automatic locomotive signalling with an inductive data transmission channel. Device comprises rails and sleepers, forming a rail-cross-box, a transformer throttle, a multichannel signal and interference generator, adjustable resistances, first and second receiving coils, a movable platform and a movable platform drive, as well as a first connection unit, a measurement and analysis unit, a display unit and a memory unit. First wheel pair is connected by its inputs to first and second rails and inductively coupled to first and second receiving coils, and the first connection unit is connected by its inputs to outputs of connected in series and opposite the first and second receiving coils, and by outputs it is connected to measurement and analysis unit, which outputs are connected to corresponding inputs of indication unit and memory unit.

EFFECT: higher level of noise immunity of automatic locomotive alarm.
