The invention provides a vehicle-mounted wheel set measuring sensor which is installed on the inner side of a wheel and comprises a camera, a laser and a controller. The controller comprises a laser control module, an acquisition module, a tread defect detection module, a tread information storage module and a communication module; the camera collects a laser strip image; the tread defect detection module obtains point cloud information, points with coordinate values exceeding a normal coordinate interval are searched in a tread area of the laser strip and marked as defect points, and coordinates of the defect points are transmitted to the tread information storage module; the tread information storage module counts the number of defect points and gives out a prompt when the defect points are abnormal; the system further comprises a rim size measurement module connected with the acquisition module and the rim information storage module. The rim dimension measurement module obtains point cloud information and calculates the geometric dimension of the rim by using the point cloud information; the rim state is monitored; according to the scheme, the sensor can dynamically monitor wheel set tread and rim conditions in real time in a vehicle-mounted mode, wheel set abnormity can be found in time, and safety is high.

    本发明提供一种车载轮对测量传感器,传感器安装在车轮内侧,包括相机、激光器和控制器;控制器包括激光器控制模块、采集模块、踏面缺陷检测模块、踏面信息存储模块和通讯模块;相机采集激光条图像;踏面缺陷检测模块获取点云信息,在激光条的踏面区域中查找坐标值超出正常坐标区间的点标记为缺陷点,并将缺陷点坐标传输到踏面信息存储模块中;踏面信息存储模块统计缺陷点的数量,在异常时,发出提示;还包括和采集模块、轮缘信息存储模块连接的轮缘尺寸测量模块;轮缘尺寸测量模块获取点云信息、利用点云信息计算轮缘几何尺寸;监控轮缘状态;本发明方案传感器采用车载的方式可动态实时监控轮对踏面、轮缘情况,及时发现轮对异常,安全性高。
