Discover Technology How It Works

The Imperative for Safety

Industrial productivity meets safety assurance.

Safety Hazards

Prevent catastrophic fires and accidents caused by idler failures and accumulated dust friction.

Equipment Failure

Early detection of bearing failures, belt tearing, and misalignment ensures seamless operations.

Economic Impact

Minimize huge economic losses and downtime through intelligent, predictive early warnings.

Core Technology

Distributed Optical Fiber
Acoustic Sensing

We utilize the optical fiber itself as both the transmission medium and the sensor. Through advanced Phase-Sensitive OTDR and Rayleigh scattering, we transform 5km of fiber into 2,500 distinct sensors.

  • Precision: Measurement pulse spacing of just 2 meters.
  • Passive: No electricity required along the belt line.
  • Resilience: Immune to EMI and corrosion.

Intelligent Signal Processing Engine

Fiber optic signals in conveyor environments are non-stationary but possess long-term stability. We adapt advanced speech processing methods (like Fbank and MFCC) to extract precise feature sets.

Technical Implementation

The fiber optic signal is segmented into frames, windowed, and subjected to STFT, Mel filtering, 1st/2nd order differencing, and DCT (Discrete Cosine Transform).

Visualizing Asset Health

Our platform transforms raw data into a simple "Health Index" for every idler on your line. Maintenance becomes predictive, not reactive.

Mobile Connectivity

Receive real-time alerts and diagnostic audio directly on your device.

Deep Learning

Targeted fault training identifies seized idlers, cracks, and bracket issues automatically.
