ILOCK is a computer interlocking system used in railway signaling and control. Key features of ILOCK include:
Safety certification: ILOCK has obtained SIL4 safety certification from international third-party authorities and CRCC product certification in China.
Redundant architecture: It uses a "2oo2×2" hardware redundancy structure for high reliability.
Safety mechanisms: ILOCK employs NISAL technology, an independent "fail-safe" CPU check module, and safety validation VPS board to ensure system safety.
Interference protection: It has strong lightning protection and anti-interference capabilities due to its multi-processor design and partitioned filtering.
Diagnostic capabilities: ILOCK can track output or input failures down to the code level with its electronic-guided diagnostic function.
Version management: It supports online version validation for process tracking and version management of system design.
Simulation testing: ILOCK includes an on-site simulation test interface with vital check-out/check-in design for simulation test data.
ILOCK is designed to provide a high level of safety and reliability for railway interlocking systems, crucial for managing train movements and preventing conflicts on rail networks.
