Electric train line positional deviation measurement system

Abstract

To provide an electric train line positional deviation measurement system which can accurately measure positional deviation amount of an electric train line even when inclination is generated in a measurement movable body during traveling.SOLUTION: An electric train line positional deviation measurement system 1 includes: a difference distance detection section which is provided in a measurement movable body 10 and detects a difference distance between a distance along a prescribed direction up to each electric train line 104a to 104c and a preset reference distance corresponding to a design position; an inclination angle detection section which detects an inclination angle in a prescribed inclination direction by defining a prescribed travel position of the measurement movable body 10 as a reference; and an electric train line positional deviation amount calculation section which calculates positional deviation amount in the prescribed direction from the design position of each electric train line 104a to 104c on the basis of the difference distance detected by the difference distance detection section. The electric train line positional deviation amount calculation section executes inclination correction processing for correcting the difference distance on the basis of the inclination angle detected by the inclination angle detection sections 33a, 33b when calculating the positional deviation amount in the prescribe direction.SELECTED DRAWING: Figure 4
