摘要:

针对轨道交通轮对几何尺寸检测需求不断增加、检测工具自动化水平低、检测精度低的现状,设计一种基于一维激光位移传感器的手持式轮对尺寸测量仪。该设备以STM32F407芯片作为微控制器,通过控制直线步进电机,配合激光位移传感器实现对轮对廓形二维点云数据的采集,采用基于中值误差与连续度调整权值的平滑算法对点云数据预处理,采用基于轮对轮廓特征的廓形匹配实现轮对尺寸参数的计算。该仪器对车轮轮廓进行全面记录和质量评估,试验证明,该设备在保持较高测量精度的情况下,同时具有高效测量、长时间工作等特点。

Abstract: Due to the increasing demand for geometric dimension measurement of rail transit wheel-set, low automation level of detection tools and low detection accuracy, a handheld instrument for wheel-set measurement based on one-dimensional laser displacement sensor was designed. The STM32F407 chip is used as the micro controller, while the points cloud data of wheel-set profile was obtained by laser displacement sensor and linear stepping motor. The instrument preprocesses the points cloud data using smoothing algorithm based on the median error and continuity adjustment weights and calculate the wheel-set dimension parameters using profile matching based on the feature in the profile data. The instrument records the whole wheel profile and evaluates its quality. The experiment proves that the instrument has high measurement accuracy while has the characteristics of high measurement efficiency and long working time.
