Vehicle Route Interaction Devices TRIZ Cases
- Rail Contact Resonant Inverter for Self-Tuned Axle Counter Frequency
A self-oscillating resonant inverter uses current-transformer feedback to avoid manual tuning and costly precision inductors in axle counters.
- Rail Track Resonance Detection for Reliable Vehicle Presence Sensing
Continuous resonance tracking and transimpedance analysis improve rail vehicle detection despite interference and vehicle variability.
- Rail Contact Element Using Optical Fiber Drop-Off Detection
An optical fiber and spring-based rail contact element detects mounting state through reflected or absorbed light, reducing complexity and fiber damage risk.
- Rail Track Circuit State Detection Using Adaptive Current Thresholds
Adaptive current monitoring helps track circuits distinguish occupied sections from broken rails despite resistance changes from weather and rail conditions.
- Vibration Alert Unit With Light and Sound for Object Movement
Threshold-triggered vibration sensing drives flashing LEDs and audible alerts to warn of unintended cargo or railcar movement in noisy settings.
- Axle Counting Masking via Virtual Track Section Fault Checks
Prior activation and time-limited masking use a virtual track section to separate transient counting-point faults from persistent failures.
- Axle Counter Train Classification Using Axle Spacing Patterns
Axle spacing patterns from axle counters classify passenger and freight trains without extra sensors, supporting safer mixed-traffic control.
- Axle Counter Signal Evaluation Using Single-Stage Deep Learning
Single-stage deep learning detects and classifies axle counter time-series signals in one step to cut false counts from interference and speed variation.
- Rail Signal Reflectometry for Cable-Free Track Condition Monitoring
Electrical signals sent through rails use time-domain reflectometry to detect train position, speed, rail breaks, and ballast issues without exposed cabling.
