FIELD: railway transport; signalling system devices, internal traffic control on block sections. SUBSTANCE: device has track generators of track circuits and receivers of track section track circuits and block section limits with track relays at output; track light signal control unit; automatic cab signalling control unit; line circuits with line relays; check and block relays; train automatic advice relay with front contacts of track section and block section limit track relays placed in advice-relay circuit belonging to first half of block section in direction of train movement, resting contact being placed in field circuit of check relay in series with parallel-connected resting contacts of track relay of track circuits of track section and block section limit belonging to second half of block section in direction of train movement; and code closing relay placed in line circuit in series with line relays and provided with field circuit formed by series-connected resting contacts of track relays of track section and block section limit belonging to first half of block section; connected in series with resting contacts indicated above is front contact of block relays, resistor and holding (blocking) circuit formed by series-connected resistor. Placed additionally in field circuit of check relay, in series with resting contact of train advice relay is front contact of line relay. Connected additionally to blocking circuit of code-closing relay, in series with parallel-connected resting contacts of track relays of track circuits of track section and block section limit of second half of block section and resistor is front contact of code-closing relay. EFFECT: enhanced safety, provision of compliance of track and locomotive light signals in case of damage of track circuit. 4 dwg |
