Railway insulation joint detection method and device

Abstract

The embodiment of the invention provides a railway insulation joint detection method and device, and the method comprises the steps: determining an image segmentation path corresponding to a target insulation joint through position information, and generating a current segmentation image set according to the image segmentation path of the target insulation joint and a current image of the target insulation joint; determining a first difference condition between each segmented image in the current segmented image set and each segmented image corresponding to a historical segmented image set closest to the current acquisition time point; and determining the current deformation condition of the target insulation joint according to the first difference condition and / or the second difference condition and / or the third difference condition. The deformation condition of the insulation joint is detected through the monitoring device installed on the train, so that the manual labor intensity of detection of the insulation joint is small, the inspection period is short, once equipment in a section is damaged, the damage can be easily found in time, interference of personnel to driving is reduced, and the probability of occurrence of personal casualty accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for detecting railway insulation joints. Background technique [0002] The insulating section in the non-insulated track circuit system is used to realize the electrical isolation between adjacent track circuits, to ensure the effective transmission of signals in this section, and to achieve the balance of power frequency traction return, which is very critical in the non-insulated track circuit system component. At present, the non-insulated track circuits used in my country's large railway lines are generally tuned non-insulated track circuits. [0003] The inspection method of railway insulation joints mainly adopts the manual inspection method. The inspectors not only have to walk dozens of kilometers at night, but also inspect the signal equipment. The inspection cycle is half a year and one month. [0004] However, the manual inspection method...

Problems solved by technology

[0004] However, the manual inspection method is labor-intensive and the inspection cycle is long. Once the equipment in the section is damaged, it is not easy to find it in time, and it will increase the interference of people on the road and increase the probability of personal injury and death accidents.
