FIELD: transport.
SUBSTANCE: invention relates to railway transport, particularly, to ACS and telemetry systems, mainly, to electric interlocking systems. Proposed system incorporates station-duty officer computerised workstation, electrician computerised workstation, hardware for data exchange between microprocessor-based interlocking system and other external info systems, two-channel device for data processing and control signal generation integrated into local computer network. Besides, proposed system comprises on-floor device control microprocessor unit connected to aforesaid two-channel device via two identical serial ports. Second on-floor device control microprocessor unit is connected via two extra serial interfaces to every said two-channel device. Outputs of said first and second on-floor device control microprocessor units are connected in OT circuit or vie extra relay circuit and via relay coupling circuit to the same on-floor devices.
EFFECT: higher reliability.
