MULTILINE TRACK CIRCUIT RECEIVER Russian patent published in 2014 - IPC B61L23/16 

FIELD: transport.

SUBSTANCE: invention relates to railway ACS, remote control and communication systems. Multiline track circuit receiver comprises two channels for processing code signals from track circuit, code signal control unit connected to track circuit state clamp-on unit and code signal control unit. Output of track circuit state clamp-on unit makes the output of multiline track circuit receiver. Starting signal unit is connected to control signal control unit. Additionally, this receiver comprises train approach and moving off with its first input connected to of track circuit state clamp-on unit and second input connected with track circuit receiver of previous track circuit. Said track circuit receiver of previous track circuit is separated from receiver of this track circuit by one track circuit. Train control unit third input doubles as the input of train motion direction change at spans while output is connected to starting signal output.

EFFECT: higher noise immunity.
