Rolling Stock and Engine Management Information System ( REMIS) by using Fibre Bragg Grating (FBG) Technology

Background:

Terminals/Goods yards/Sidings are very important for train running. Trains originate from terminals/goods yards/sidings and also terminate. At present, these terminals/goods yards/sidings are not equipped to provide irst – hand visual information regarding engines and rolling stock entry and exit in each line/entire terminal/ yard/siding.

Introduction

REMIS is being designed and developed to provide Management Information System of Rolling stock and Engine:

  • Entry and Exit of Engine and also Rolling Stock on Real Time
  • Stock of Engine and Rolling Stock in each line
  • Stock of Engine and Rolling Stock in terminal/good yard/siding
  • Loaded/Partially Loaded/Empty
  • Weight of the wagon

REMIS can also monitor uneven loading of wagons and also condition of wheel i.e lat wheel.

FBG Concept:
The FBG operates like an optical ilter i.e. it relects certain wavelength of light while it transmits others. Fibre Bragg Gratings convert mechanical strain variation into an optical wavelength shift.
Strain caused on the FBG sensor would make wavelength to get shifted to detect/sense parameters.

FBG fabrication:
FBG is fabricated by exposing photosensitive ibre core to pulsed UV laser through optical phase mask.
