Abstract

Rail straightness measurement is critical in rail production, in which the detecting speed, accuracy and stability directly affect the overall rail production. In this paper, using modern technology such as laser sensors, data acquisition, and computing technology, an innovative rail straightness measurement method was designed and implemented based on parallel computing. In the design, 14 laser displacement sensors and 2 rotary encoders were used to measure respectively 7 level displacements, 7 vertical displacements, and rail transmission displacement in real-time. After those signals conversed to digital and transferred to server computer, CPUs and GPUs will: 1) synchronous matching, 2) inner block analyzing, 3) block analyzing, 4) frame analyzing, 5) straightness analyzing. The disturbing factors, such as iron oxides, side sliding, low frequency vibrations, and high frequency vibrations were and eliminated. Finally, get the rail straightness information and output, save, transfer, or used to guide production. Experiments and practical application show that, the method not only is feasible, but also it detection speed can up to 3m/s, and accuracy up to 0.05mm.
