System Overview¶
Introduction¶
RailwayMitra is an autonomous track geometry inspection system developed by ERIC Robotics Pvt. Ltd.
It is designed to replace manual and semi-manual track inspection methods with a self-propelled, sensor-fused platform capable of measuring track geometry parameters continuously at inspection speeds.
Target Users¶
| Role | Use Case |
|---|---|
| ERIC Field Operators | Deploying and operating the system on-track |
| ERIC Engineers | Data analysis, calibration, firmware updates |
| Client PWI / SSE (P.Way) | Reviewing inspection reports and Format C data |
| Trial Coordinators | Managing corridor access and scheduling |
Architecture Overview¶
The system comprises three main subsystems:
1. Mechanical Platform¶
The inspection trolley — a rail-mounted, self-propelled platform carrying all sensor and compute hardware. Designed for gauge-adaptive operation across BG (1676 mm) and standard gauge corridors.
2. Sensor Suite¶
- Laser Rail Profilers — Left and right rail head profile measurement (0.105 mm X resolution, 2 um Z repeatability)
- IMU — Inertial measurement for roll, pitch, yaw
- Wheel Encoder — Odometry for distance-based sampling
- GNSS Receiver — Geo-tagging of measurement positions
3. Compute & DAQ¶
- Edge compute unit running the data acquisition pipeline
- IPC via iceoryx (zero-copy, lock-free)
- Per-service MCAP recording with mission-based folder structure
- Real-time dashboard for operator feedback
Measured Parameters¶
| Parameter | Description | Reference Standard |
|---|---|---|
| Gauge | Distance between inner faces of rail heads at 14 mm below rail top | IRPWM Chapter II |
| Cross-level | Relative height difference between left and right rail | EN 13848-1 |
| Alignment | Lateral deviation (versine method) | IRPWM Chapter II |
| Twist | Rate of change of cross-level over base length | EN 13848-1 |
| Unevenness | Vertical profile irregularity | EN 13848-1 |
