【摘要】 本文提出了一种基于最小二乘拟合的轮对轮缘在线检测系统。该系统由双传感器加TMS320F2812数字信号处理器完成数据采集,由测量模型导出计算模型,应用最小二乘拟合建立采集数据到轮缘厚度的映射函数,二次应用最小二乘拟合结合先验条件对被测点准确定位后得到检测结果。经实际应用验证,该系统简洁实用可靠,测量精度可达±0.1mm。更多还原

【Abstract】 This paper proposes an online detection system of flange based on Least Square Collocation (LSC). Data collection module of the system is composed of double sensors and TMS320F2812 DSP. The calculation mode is educed from measure mode. LSC is firstly applied to build function between sampling data and flange thickness. With some known measure rules,LSC is applied again to obtain the exact position of expected point and detection results. Demonstrated by application,the system is reliable and practical,and measure precision can be reached.更多还原
