Distributed Acoustic Sensing
Turns standard optical fibre into a continuous acoustic sensor for intrusion, third-party interference, and asset health.
Specification
DAS interrogates existing fibre and classifies vibration signatures along the entire route. Walking, digging, vehicle movement, rail-break acoustics, and pipeline TPI are detected in real time without installing a field sensor every few metres.
Capabilities
- Continuous sensing along the fibre, no discrete sensors
- Event classification for walk / dig / vehicle / rail
- Pipeline intrusion and perimeter modes
- Integration with RFMS and SCADA
- Low false-alarm tuning for Indian operating conditions
Applications
- Trackside security
- Pipeline ROW
- Perimeter defence
- Metro tunnels
