MICROPROCESSOR-BASED AUTOMATIC INTERLOCKING SYSTEM Russian patent published in 2010 - IPC B61L27/04 

FIELD: transport.

SUBSTANCE: invention relates to automatic hardware to control train traffic intervals. Proposed system comprises railway traffic dispatching station, computer-aided work stations with independent PCs to control system operation, units to control floor signal transducers, local transmission systems, I/O units, protection units, two channels to process signals from axle count units with path control transducers and floor signal transducers, circuit to generate automatic locomotive signaling signals, unit of stationary devices of electric centralisation, circuit to control availability of signaling readings at input traffic light, circuit to control availability of clear signal to access main running line, circuit to control availability of clear signal to access side running line, circuit to control availability staff at station supervisor control board, relay to control openness of the first remote section and first protection section behind the first remote line at traffic light, relay to control openness of second remote section and first protection section behind the second remote traffic light, remote monitoring unit, main and standby station computing units, first and second differential units. First group of outputs of the main and standby station computing units makes the group of outputs to points of connection to code transmission rail circuit via automatic locomotive signaling circuit. Second group of outputs of the main and standby station computing devices makes the groups of actuating outputs to connect the traffic light lamps cut-in circuits.

EFFECT: higher fail-safety at stations and station limits.
