Interlocking system

Mipro’s computer-based fail-safe interlocking system is developed to control and manage high-frequency and demanding rail operations. The modular and flexible system architecture enables various traffic and operation modes, future expansions and modifications, as well as easy integration in existing infrastructures.

The system is suitable for controlling main lines, marshalling yards and low-density lines. It meets the highest requirements stipulated for systems related to the railway safety and provides Safety Integrity Level 4 (SIL4) for hardware and software.

FLEXIBLE SYSTEM ARCHITECTURE

Mipro’s interlocking system supports distributed, centralised and mixed system architectures. Thus it provides an appropriate architecture for each environment and helps optimise the need for cabling and device facilities. The modular system structure also enables an efficient use of railway capacity.

ADAPTABLE INTERFACES

Mipro has the knowledge and know-how to integrate various systems and make them function safely together. One of the system’s key features is its easy adaptation to the existing infrastructure.

SAFE AND SECURE COMMUNICATION

Mipro’s interlocking system connects to external systems through open standardised interfaces. The communication based on the Ethernet network guarantees a reliable data transmission without delays.

MODULAR AND MAINTENANCE FREE SYSTEM PLATFORM

Mipro’s interlocking system is suitable for mainlines, low density lines, urban lines, marshalling yards, depots and industrial railways. Its platform is based on COTS components and modern PLC technology. Safety is ensured by the 2oo2 processor architecture and redundancy of critical components such as CPUs, PSUs and network devices.
