Distributed Acoustic Sensing
Distributed Acoustic Sensing (DAS) is a cutting-edge technology that uses optical fiber to sense and identify multiple parameters over extended distances remotely.
The technology leverages the Rayleigh backscatter theory to detect vibrations and sounds along the fiber
Industry Leading Technology
Fiber optic-based Distributed Acoustic Sensing (DAS) leverages existing fiber optic cables to detect and analyze acoustic signals along their length using Rayleigh scattering.
By sending continuous laser pulses and analyzing the reflected signals, DAS systems can monitor vibrations and sound waves in real-time.

Elephant Intrusion Detection System
Vibrations along railway tracks are being captured, using advanced signal processing to identify the distinctive seismic signatures of elephants. This real-time detection enables immediate alerts with precise geo location to train operators, preventing collisions and enhancing safety.
Applications
Track Condition Monitoring
Tracks are continuously monitored and adeptly identify structural anomalies such as fractures, broken rails, and irregularities in alignment. Subtle variations in acoustic and vibrational signatures are analyzed, allowing these defects to be detected in real time.
Flat Wheel Detection
Defective flat wheels generate unique vibrational patterns during movement, which are meticulously analyzed, allowing these defects to be identified before any operational issue.
Track Detection Unit
DAS technology is capable to work as Track Detection Units by continuously monitoring vibrations along railway tracks to detect and identify trains entering and exiting stations. Precise train locations are determined without the need for physical detection equipment on the tracks.
Train Location Identification
Train locations are identified and mapped using Geographic Information Systems (GIS) combined with precise distance measurements and real-time speed tracking. This enables accurate monitoring of train movements
Pipeline Monitoring
Fiber optic cables are installed alongside pipelines to detect vibrations and disturbances affecting the pipeline's integrity. It capture movements from leaks, unauthorized digging, tapping, or environmental factors.
Perimeter Intrusion
Detection of subtle disturbances along security boundaries that indicate unauthorized activities like trespassing or digging. Advanced signal processing techniques analyze these vibrational patterns to prevent breaches.
Construction/Digging Near Track
Irregular activities near railway tracks, such as construction or digging, are identified by capturing unusual signatures using advanced signal processing techniques. Allowing immediate alerts to be sent to prevent accidents and enhance safety around the rail infrastructure.
Level Crossing Gate Approaching
Train movements are captured and meticulously mapped using Geographic Information Systems (GIS) to identify trains approaching level crossings (LC Gates). Alerts are dispatched via LTE or wired communication networks to specific LC Gate operators, enabling prompt safety measures to prevent accidents.
