Abstract: An apparatus for detecting a position of a train, the apparatus includes a reader. The reader electrically irradiates beams along a plurality of directions toward a tag, combines signals received from the tag and obtains a beam direction information toward the tag, and then detects the position of the train using the beam direction information and a tag information of the tag.

Abstract: In a method for detecting rail fracture, vibration data generated according to train operation is inputted, and the vibration data is collected using a distributed acoustic sensing (DAS) system. The inputted vibration data is imaged into the relationship between time and frequency. The imaged image is learned. Rail fracture of train is decided from the imaged vibration data, based on the learning.
