    • PURPOSE:To simplify the structure and the jobs of a data collecting device and also to improve the reliability of the device by using directly the curve position and the shape signal measured by a gyroscope mounted on a truck for the purpose of control after correction of a waveform. CONSTITUTION:A data measuring part (sensor) 1 uses a 1m pulse signal a1, for example, of a pulse type velocity generator and a detection signal a2 of the ground element of an automatic train stop ATS device as the reference of distance. Then a truck frame rolling angular velocity signal a3 and a truck frame yawing angle signal a4 are measured by a gyroscope. A track shape data collecting device 2 eliminates the high frequency components of both signals a3 and a4 through a proper LPF to correct them into the proper waveforms as the control signals b1-b4 and c1-c4 used for control of the tilt and vibration of the truck body. Furthermore, the device 2 functions to secure the matching of timing among those signals b1-b4, c1-c4, a1 and a2.
