FIELD: electricity.
SUBSTANCE: device comprises opposed locomotive receiver coils and locomotive decoders of the automatic cab signalling, two summators based on analogue operating amplifiers with non-inverting input of the first summator connected to the locomotive coils and with inverting input of the first summator through a phase shifter is connected to a programmable low-frequency filter, while output of this summator is connected to non-inverting input of the second summator. The inverting input of the second summator is connected through the second phase shifter to a programmable rejection filter. The automatic control device impacts the programmable rejection filter and programmable low-frequency filter acting as a useful signal frequency detector. Output of the second summator is connected to the receivers of the automatic cab signalling.
EFFECT: increased safety and clearance of train traffic.
