DEVICE FOR RECEIVING SIGNAL FROM TRACK CIRCUIT Russian patent published in 2016 - IPC B61L23/16 

FIELD: transport.

SUBSTANCE: invention relates to railway automation and telemechanics. Device includes receiving unit of amplitude-modulated signal, input of which is connected to inputs of signal nonlinear processing and spectral processing unit of signal, nonlinear processing unit output and spectral processing unit output are connected to first and second inputs of OR element, output of which is connected to amplifier input with track relay connected to its output. Additionally, unit for generating adjustment control signals connected with adjustment channel analysis unit, input/output of which is intended for connection through communication unit to external non-volatile memory. At that, amplitude-modulated signal reception unit, nonlinear processing unit, spectral processing and amplifier are made controlled, and their control inputs are connected to first, second, third and fourth control outputs of adjustment control signals generation unit.

EFFECT: achieved is possibility of obtaining false information on state of rail circuit.
