The Problem — Unsafe Track Work Environments

Track maintenance, doubling, and electrification often occur while trains are active. Manual communication via walkie-talkies is slow, unreliable, and leads to tragic accidents and delays.

  • ❌ Manual, people-dependent alert chains
  • ❌ Delayed or missed warnings
  • ❌ Multi-track ambiguity
  • ❌ Harsh terrain and weather constraints

The Solution — Rugged IoT-Based Radar + LiDAR System

A portable IoT-powered radar + LiDAR system that detects trains and instantly alerts work crews via smart hooters and LED indicators — even 10 km away.

Immediate Alerts

Worker safety ensured through smart hooters & LEDs.

Millisecond Detection

Edge-processed alerts with no network dependency.

Reliable Power

Built-in rechargeable battery for remote operation.

All Terrain Operation

Performs in tunnels, forests, cuttings, and bridges.

How It Works

Train Detection (Edge)

Radar + LiDAR detect incoming/outgoing trains across tracks. Weatherproof & battery-powered.

Alerting (Field)

Smart hooter emits directional tones and LED flashes for quick crew response.

Visibility & Control (Cloud/On-Prem)

Dashboard shows alerts, telemetry, and device status with role-based access.

Frequently Asked Questions

Does it work without network?

Yes — local detection and hooter alerts continue even offline. Data syncs automatically when network restores.

Can it handle multiple tracks?

Yes — it distinguishes between directions and multiple tracks using dual radar mapping.

Can we host the system on-premises?

Absolutely. Both cloud and on-premises deployments are supported with full RBAC and white labeling.
