Intelligent control method for ballastless track steel rail laying process
The invention discloses an intelligent control method for a ballastless track steel rail laying process, and particularly relates to the field of track laying. A visual sensor and a position sensor are arranged at each steel rail connecting piece, real-time position coordinates of the steel rail are acquired by utilizing the visual image; a manipulator is controlled to grab the steel rail according to the real-time position coordinates of the steel rail; the moving track of the steel rail is calibrated through the guide frame and the bracket according to the real-time visual information, and when the steel rail is guided out from the transition device, the center line of the ballast bed can be accurately aligned; meanwhile, the movement of the manipulator is controlled by utilizing the steel rail real-time coordinates obtained by the visual images so that when the steel rail is grabbed and fixed by the manipulator, the grabbed position coordinates can be kept consistent with the calibrated position coordinates, and the laying accuracy of the steel rail is not influenced by the position deviation of the construction operation vehicle.
本发明公开了一种无砟轨道钢轨铺设过程的智能控制方法，具体涉及轨道铺设领域。本发明通过设置于各钢轨交接件处的视觉传感器和位置传感器，利用视觉图像获取钢轨的实时位置坐标，并根据钢轨实时位置坐标控制机械手抓取钢轨，并根据实时视觉信息通过导框和托架对钢轨的运行轨迹进行校准，使得钢轨从过渡装置导出时能够精确的对齐道床中心线，同时利用视觉图像获取的钢轨实时坐标，控制机械手的移动，使钢轨在被机械手抓取固定时，能够保持抓取后位置坐标与校准后位置坐标的一致，保证钢轨铺设的精确度不受施工作业车的位置偏差影响。
