Abstract

The detection of the rail straightness is crucial to the maintenance of the track. This paper designed a rail straightness detector based on laser displacement sensor. Based on the theoretical analysis of the detection error of the detector, the error analysis platform of the detector is built based on the working face of the precision marble measuring block. The mobilized medium moving average filtering algorithm and the linear fitting calibration method are treated with the random error and systemic error of the detector data collection system; The vibration error was tested and analyzed, and the laws of various errors were obtained. The minimum daily method was used to fit the system variable error, which provided error compensation measures for the detector.
