Point Operation From Vehicle TRIZ Cases
- Railway Switch Position Reporting Using Onboard Image Verification
Onboard cameras and code reading verify unmonitored railway switch positions, replacing error-prone manual reports with accurate record updates.
- Rail Switch Request Control for Nearest-Train Locking
By verifying the nearest train before switch movement and locking, this case prevents conflicting rail switch requests and unsafe overrides.
- Train-Ground Coordination for Hierarchical Rail Resource Control
Hierarchical section control plus direct train-to-train coordination improves rail resource sharing, timeliness, and passing capacity.
- Decentralized Interlocking Track Device Wireless Route Management
Wireless autonomous interlocking track devices eliminate centralized wiring complexity by managing route reservations directly with guided vehicles.
- Central Controller Emulating On-Board Vehicle Control
A central controller emulates on-board vehicle functions for unequipped railway units using trackside signals.
- Conveyance System Obstacle Detection for Restricted Area Entry
Optical and contact sensors detect entry markers to prevent unauthorized carriage movement into restricted zones.
- Decentralized Railway Switch Control via Wireless Train Communication
A decentralized railway interlocking system uses onboard microcontrollers and wireless transceivers to manage switch positions directly from trains.
- Train Navigation System Using Inertial Sensors
Inertial sensors replace trackside hardware to resolve GPS reliability issues in obstructed environments.
