Problems solved by technology

The traditional manual inspection method has a large workload and can only be carried out within a very limited skylight time, which is difficult to meet the needs of efficient maintenance of a large number of high-speed railway catenary
Manual inspection of the 4C system detection method Due to the changeable catenary suspension structure and many types of defects, technicians need to observe many different types of faults in a single image, which makes it difficult to improve work efficiency

Embodiment 1

[0050] This embodiment provides an image processing-based positioning clamp drop-off detection system, including a positioning clamp image acquisition terminal and a positioning clamp image processing terminal, and the positioning clamp image acquisition terminal captures the positioning clamp image and transmits it to the positioning clamp image processing end, and the image processing end of the positioning wire clamp processes the image to judge whether the positioning wire clamp falls off in time.

[0051] Specifically, the image acquisition terminal of the positioning line clamp: collects the image of the positioning line clamp of the catenary, and sends the image of the positioning line clamp to the image processing end of the positioning line clamp. Positioning clamp image processing end: process and analyze the positioning clamp image, judge whether the positioning clamp has fallen off, and send an alarm if it falls off; and after superimposing the positioning clamp pos...

Embodiment 2

[0063] Based on Embodiment 1, this embodiment provides an image processing-based detection method for positioning wire clamp falling off, including the following steps:

[0064] S1, when the locomotive is running, the trigger unit sends an image acquisition trigger command to the image acquisition unit according to the running speed of the locomotive, and at the same time sends a supplementary light trigger command to the supplementary light unit; the image acquisition unit and supplementary light unit start to work;

[0065] It should be noted that the trigger unit sends relevant trigger commands according to the running speed of the locomotive. When the running speed of the locomotive is faster, the trigger command is sent at a shorter time interval, and when the running speed of the locomotive is slower, the trigger command is sent at a longer time interval;

[0066] S2, after the image acquisition unit receives the image acquisition trigger command, it captures the image of...

Abstract

The invention discloses a positioning wire clamp falling detection system and method based on image processing, and the method comprises the steps: enabling a positioning wire clamp image collection end to collect a contact network positioning wire clamp image, and transmitting the positioning wire clamp image to a positioning wire clamp image processing end; the positioning wire clamp image processing end processes and analyzes the positioning wire clamp image, judges whether the positioning wire clamp falls off or not, and gives an alarm if the positioning wire clamp falls off; and after thepositioning wire clamp position information is superposed on the positioning wire clamp image, the positioning wire clamp image is stored. According to the invention, a method based on image processing is adopted; real-time positioning detection can be carried out on the positioning wire clamp, comprehensive analysis is carried out on the working condition of the contact net positioning wire clamp according to the processing result, timely and effective data are provided for overhauling, the state of the positioning wire clamp is known in time, accidents are prevented, driving safety is guaranteed, the processing speed is greatly increased, manpower and material resources are saved, and the accuracy is higher.

Description

technical field [0001] The invention relates to the field of detection of catenary positioning wire clamps, in particular to an image processing-based detection system and method for positioning wire clamps falling off. Background technique [0002] With the continuous development of high-speed and heavy-duty railways, due to the increase in the tension of catenary wires and catenary cables in high-speed railway catenaries, the stress and vibration of catenary components have also greatly increased, and the safety of catenary components is particularly prominent. The catenary is a special form of transmission line erected along the railway line, which provides reliable and continuous electric energy for electric locomotives through the direct contact between the catenary wire and the pantograph. It is an important equipment of electrified railway, which is composed of contact suspension, supporting device, positioning device, pillar and foundation. In order to ensure the sa...
