提出了一种基于激光基准的轨道平顺度检测仪,其可以对轨道的高低不平顺度、轨向不平顺度和曲率进行检测。轨道检测仪以激光为基准,利用水平仪和远程聚焦系统使激光垂直入射到光电靶面上,通过数据采集单元采集数据并将数据传送给数据处理单元,得到轨道的不平顺参数,并在人机交互界面上显示。实验结果表明,该轨道检测仪可靠性高,测量精度高,检测距离可达200 m,测量精度为1 mm。

A railway track smoothness detector based on laser reference is proposed, which can detect height irregularity, alignment irregularity and curvature. The detector uses laser as reference and uses gradienter and remote focusing system to make laser irradiate the photoelectric target vertically. The data is collected through the data acquisition unit and is transmitted to the data processing unit. The track irregularity parameters are obtained and displayed on the human-computer interface. The experimental results show that the proposed detector has high reliability and high accuracy. The detection distance can reach 200 m and the measurement accuracy is 1 mm.
