Dynamic Test of High-Speed Transponder System for Rail Transport

초록

The position and velocity information for high-speed trains (HST) is necessary for low maintenance cost, enhanced operational safety and efficiency. Recent HST navigation systems use multi-sensors, such as tachometer, accelerometer, gyroscope, GPS, and transponder in order to obtain accurate position information in harsh railway environments. In order to detect the exact position of a HST, it is necessary to receive telegrams transmitted by transponder tags installed along the track. In this study, we investigated the performance of a high-speed transponder system developed as a HST navigation system.
