<P>PROBLEM TO BE SOLVED: To reduce man-caused operations during measurements on a vehicle traveling on a rail track in making inspection value data output time-sequentially from a sensor installed in the vehicle traveling on the rail track correspond to rail track position data. <P>SOLUTION: In synchronization with the inspection value data or as the inspection value data, angular velocity data of at least one axis and acceleration data of at least one axis are successively acquired by an angular velocity sensor and an acceleration sensor installed in the vehicle and are stored time-sequentially. The data whose stored angular velocity data is within a prescribed range from a fixed value and the acceleration data within a prescribed range from the fixed value is determined as the data of being at a vehicle stop position. With respect to the inspection value data between two vehicle stop positions, the traveling distance from one vehicle stop position is acquired and, from the acquired traveling distance, the rail track position data is acquired by referring to a table in which the position of a station is made to correspond to the rail track position data, and the rail track position data is made to correspond to the inspection value data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
