AI Technical Summary
After a period of use, the accuracy of the sensor measurement system of the tamping machine decreases due to wear and tear of the measuring trolley or damage to parts. On-site calibration is difficult, time-consuming and labor-intensive, and it is difficult to achieve high-precision calibration on non-standard tracks.
A rapid calibration method on the tamping machine line is adopted. By installing auxiliary calibration devices on near-straight road sections, static horizontal, vertical, and directional calibration is performed. Combined with liquid level contour measurement, the sensor system can be calibrated quickly.
It improves the accuracy and efficiency of sensor calibration, simplifies the operation process, realizes automatic verification of sensor parameters and data sharing, and shortens the calibration time.
