Embodiment Construction
[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0035] see figure 1 , the intelligent identification method of track obstacles provided by the present invention will now be described. Track obstacle intelligent identification methods, including:
[0036] Distributed optical fibers are laid along the length of the track, and multiple detectors are installed at intervals along the length of the track.
[0037] When the obstacle falls on the track and the change value of the distributed optical fiber state exceeds the preset standard, the distributed optical fiber feeds back the position information, and rais...

The invention provides an intelligent track obstacle identification method, which belongs to the technical field of obstacle identification, and comprises the following steps: laying distributed optical fibers along the length direction of a track, and installing a plurality of detectors at intervals along the length direction of the track. When the obstacle falls on the track and the change value of the state of the distributed optical fiber exceeds a preset standard, the distributed optical fiber feeds back the position information, and the detector close to the position information is lifted; and determining the distance with the obstacle and the size parameter of the obstacle through the detector. And deducing the mass of the obstacle according to the change value and the size parameter, and performing corresponding elimination work according to the mass to reset the detector. According to the rail obstacle intelligent identification method provided by the invention, the obstacle can be sensed in time through the distributed optical fibers, the distance between the rail and the obstacle, the size parameters and the quality can be determined through the detector, visual and accurate data are provided for obstacle clearing work, and normal operation of a train is ensured.
Description
technical field [0001] The invention belongs to the technical field of obstacle identification, and more particularly, relates to an intelligent identification method for track obstacles. Background technique [0002] Rail cars usually use the on-board video monitoring system to record the information while driving, and the driver can check it afterwards through the stored video data after the driving is completed. In order to improve efficiency and safety, reduce energy consumption, reduce operation and maintenance costs, and improve labor intensity, automatic driving of rail cars has become an inherent requirement for the development of railway technology in my country. [0003] The types of rail transit obstacles include not only pedestrians and livestock illegally on the road, but also rocks and trees caused by natural disasters. Therefore, research on the detection of obstacles in front of trains is of great significance to ensure safe railway transportation. Traditiona...
