The Indian Railways has initiated process to launch the Terrain Imaging for Diesel Drivers- Infrared Enhanced Optical and Radar Assisted (Tri-NETRA) system to avoid train accidents.
The system will be installed on locomotives for enhancing the vision of Locomotive Pilots in inclement weather.
About Tri-NETRA system
The device uses infrared and radar technology to collect signals up to a distance of 2-3 km and displays the information (composite video image) on a screen fitted inside the locomotive.
The Tri-Netra will alert the drivers of any physical obstruction on railway tracks ahead and thus give ample time for the driver to apply the brakes to prevent train accidents.
It will be very useful during fog, heavy rain and nights, when drivers have to constantly look outside the locomotive to judge the condition.
Three components of the system: It is made of high sensitivity infra-red video camera, high-resolution optical video camera and a radar-based terrain mapping system.
These three components shall act as three eyes (Tri-Netra) of the Locomotive Pilot.
Background
The concept of TRI-NETRA was developed by Development Cell under the guidance of Member Mechanical, Railway Board.
Specifications and design of critical components of the system will be approved by the Research Designs & Standards Organisation, the railways research arm.
TRI-NETRA system is based on technology employed by fighter aircrafts to see through clouds and operate in pitch darkness.
It is also based technology used by naval ships in mapping the ocean floor and navigating in the night.
