摘要： A track displacement detecting and measuring system in which track displacement data are obtained as usual for a unit chord length of the track according to the conventional three-point measuring method by sensors mounted on three predetermined parts of a track inspection car, and such measured data are processed by an arithmetic or processing device of relatively simple structure to detect the amount of track displacement occurring over a track distance which is two or four times the unit chord length. In the system, an improved gyro device free from the adverse effect of rolling of the car is employed so as to permit precise detection of vertical track displacement irrespective of the track distance. The system includes reflecting members of stainless steel disposed at a predetermined angle with respect to the track, a laser pulse projector, a reflected pulse receiver and a signal processing circuit so that errors of distance marks used for the recording of measured data can be corrected stably and with high precision.
