Embodiment 1

[0216] Embodiment one, such as Figure 11 Position the strut assembly as shown:

[0217] First, find the left edge of the pillar part: traverse the binarized image line by line from left to right, scan the downward fan-shaped area of ​​each pixel in each row, and there are n pieces in the downward fan-shaped area with the pixel For the downward scanning line segment with the point as the origin, count the number L1 of black pixels on the left and the number R1 of white pixels on the right of each downward scanning line segment in the downward fan-shaped area. When the number L1 and the number R1 account for the corresponding downward scanning When the length of the line segment is a certain proportion, it is determined that the downward scanning line segment in the downward fan-shaped area is the left edge of the pillar component.

[0218]Second, find the suspected right edge of the pillar component: After finding the left edge, continue to scan the downward fan-shaped area o...

Abstract

The invention discloses a safety monitoring analysis system for contact net running state. The safety monitoring analysis system for contact net running state comprises a first camera, a second camera, an image rectification unit, a pantograph recognition unit, a contact line recognition unit, a model database, a geometrical parameter calculation unit and a defect recognition unit, wherein the defect recognition unit comprises a pantograph deformation defect recognition unit, a component fall-off defect recognition unit, a pantograph pull-out overrun defect recognition unit, an arcing defect recognition unit, a high temperature interference recognition unit and an accident pantograph falling-down defect recognition unit. The safety monitoring analysis system for contact net running state can detect and recognize defects, comprising contact net defect, pantograph defect and pantograph-net relationship defect, existing in the contact net in real time according to pantograph recognized by the pantograph recognition unit, a contact line recognized by the contact line recognition unit and/or geometrical parameters output by the geometrical parameter calculation unit. The safety monitoring analysis system for contact net running state can carry out online monitoring on the pantograph-net relationship without interfering transportation order of operating vehicles and timely find out abnormal defects existing in the pantograph and contact net.

Description

technical field [0001] The invention relates to the field of catenary, in particular to a safety monitoring and analysis system for the operating state of the catenary. Background technique [0002] In the electrified railway, the catenary is the main power supply equipment of the electrified railway, and the electric locomotive obtains electric energy through the catenary. Pantograph-catenary relationship plays an important role in the normal operation of the entire electrified railway operation system. In order to ensure the reliability of catenary operation and the good current receiving performance between pantograph and catenary, it is very important to detect the relationship between pantograph and catenary and grasp the status of catenary parameters at any time. The catenary carries a huge traction current during operation, and faulty catenary wire clamps and other parts may cause temperature anomalies, catenary geometric parameters exceeding limits, etc., which may ...
