Railway Traffic Control Systems TRIZ Cases
- Train Deviation Propagation Analysis via Multi-Layer Coupling
Multi-layer coupling recognition extracts train activity data to identify deviation propagation conditions.
- Logic Circuit Emulating Safety Relay Contacts
Dual-channel logic circuit mimics safety relay contacts using transistors to manage signal voltages, preventing route blockages during FPGA migration.
- Wayside Unit Testing via Virtual Vehicle Simulation
Software simulation replaces physical vehicles to test wayside units, reducing network downtime and resource consumption during integration checks.
- Train Control System Dynamic Resource Allocation
Dynamic resource allocation transitions routes between exclusive and shared states, resolving conflicts that limit transport capacity.
- Task Schedule Creation for Railroad Vehicle Inspection Constraints
A task schedule creator generates cyclic schedules using restriction conditions on implementation frequency and period length.
- Secure Operator Station Computer Mediator Architecture
A secure operator station computer mediates commands from insecure terminals to interlocking systems via dedicated data connections.
- Rolling Stock Scheduling via Operation Connection Graph
An operation connection graph assigns rolling stock operations to cars using greedy and backtrack search units.
