A Development of Real-time Monitoring System in the Gauge Change Facilities using Fiber Optic Sensor Technology

초록

A gauge-changeable system can be a better solution for the fast and safe railway transportation between two countries with different gauges than transshipment or bogie-changing at the border of each country. Especially in Korea, it is very essential for connecting the trans-Korean railway with the transcontinental railway effectively. So far, conventional type sensors like gap sensors or strain gauges are used for the monitoring system during gauge change processes. They are also based on electric type sensors. In this paper, a novel and simple real-time monitoring system in the gauge change facilities is developed and verified using fiber optic sensor technology, which is immune to electromagnetic interference (EMI) caused by high-voltage electric power feeding system.
