  Abstract

The orbital gauge is used for safe train operation by checking the state of the current orbit and maintaining the optimal condition of the track because the state of the orbit changes due to vibration and lateral pressure of the train. Conventional orbital gauges have confirmed the scales to know the distance between orbits and the distance between orbit and guardrail track, and the leverer has been manually operated using fine adjustment screws. In addition, the working time has been greatly affected by the skill in use of the orbital gauge because it has been possible to make measurement only by carrying the flash to read the scale when the work has been performed in the tunnel. In order to complement this disadvantage, the laser distance sensor is operated to measure the distance and the LCD shows the measured value, and the horizontal gyro sensor is used to express the tilted direction from 0 to ±90 degrees.
