Novel application of a fibre optic-based train weigh-in-motion system in railway

摘要

A fibre optic-based train weigh-in-motion system using Fibre Bragg grating (FBG) sensors was implemented in a railway system. The purpose of the system is for real-time train vibration and wheel load monitoring. Using an FBG sensor in railway is a novel application. A method for bridging experimentation and practical use is established.
