Railway Traffic Control Systems TRIZ Cases
- Multi-Channel Train Radio Relays for Reliable EOT-HOT Communication
Multi-channel radio relays maintain EOT-HOT communication across long trains.
- Railroad Car Group Separation Detection via Track-Side Relay
Front and rear cars relay position and speed status through track-side facilities for separation checks without equipping middle cars.
- Railcar ETA Prediction Using Engineered Features for Multi-Carrier Trips
A trained ML model combines trip data and rail-station coordinates to predict railcar ETAs and trigger fleet readiness alerts.
- Railway Car Combination Separation Detection via Trackside Communication
Front and rear car status checks use trackside communication devices for reliable separation detection without equipping middle wagons.
- Rail Vehicle Abnormality Detection via Body Vibration Analysis
Vehicle-body vibration and operation data identify abnormal vibration causes without extensive axle and bogie sensors.
- Root Pump Pressure Loading for High-Speed Train Fatigue Tests
A movable root pump and valve network controls alternating pressure waveforms without large chambers or permanent train-body modification.
- Carborne Controller for CBTC Work Train Positive Train Stops
The controller localizes work trains, receives CBTC and physical signal aspects, and enforces positive stops without full onboard CBTC.
- Mobile Radio Antenna Separation for Rail Vehicle Interference Control
Dedicated transmit antennas and a shared receive antenna limit feedback for reliable rail vehicle radio communication.
- Configurable Rail Process Data Transmission Without Relicensing
A configurable controller and diagnosis server adapt rail process data transmission without software relicensing or reinstallation.
- Railroad Switch Point Machine Diagnosis Using Component-Mapped Event Signals
Compare sensor time series and simulation-mapped event points to identify faults in individual railroad switch components.
- Virtual Approach Signals for Real-Time Railway Block Upgrades
Virtual signals update railway blocks in real time, reducing avoidable speed restrictions.
- Virtual Approach Signal Upgrades for Real-Time CTC Track Blocks
Real-time virtual approach signals update PTC terminals, helping trains accelerate while protecting switches, broken rails, and hazards.
- Railroad Signaling Equipment Status Monitoring for Predictive Alerts
Remote telemetry and adaptive analytics detect atypical maintenance conditions and predict railroad crossing signaling failures.
