FIELD: signaling means.
SUBSTANCE: technical solution relates to automatic locomotive signaling means for determination of signals of ahead traffic lights, conditions of switches and track devices, indication of distance between trains. Device comprises analogue magnetic field sensor, amplifier, analogue filter, ADC, digital filtration unit, ring buffer, digital signal analyzer and control device. At that, sensor, amplifier, analogue filter, ADC, digital filtration unit, circular buffer, digital signal analyzer and control device are connected to each other in series through signal inputs / outputs, first output of control device is connected to control input of digital filtration unit, and second output of control device is connected to control input of digital signal analyzer.
EFFECT: high noise-immunity against the background of additive interference and reliability of automatic locomotive signaling in a wide range of signal amplitudes independent of interference phases.
