Embodiment Construction

[0025] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Embodiments of the present invention provide a method for retrieving rail transit catenary defects, such as figure 1 shown, it includes the following steps:

[0027] S1: Obtain the defect ID in the catenary detection alarm information; the defect ID includes the catenary one rod and one gear ID, serial number and defect level. The catenary detection alarm information comes from the 6C system and so on.

[0028] The catenary one-rod, one-file ID is the existing technology, which consists of four levels, which represent the affiliation and position of the catenary components and equipment:

[0029] The first digit of the first level includes the flexible system (1) and the rigid system (2), and the last two digits include pillars...

Abstract

The invention provides a rail transit overhead line system defect retrieval method. The method comprises the following steps: S1, acquiring a defect ID in overhead line system detection alarm information; s2, according to the defect IDs, obtaining one-rod one-gear IDs of all the contact networks within the range of KP +/-Kn, and forming a one-rod one-gear ID set of the contact networks; wherein Kn is a defect expansion range parameter, and the unit is meter; s3, querying a defect matrix according to the defect ID, and screening out a confirmation defect set with the correlation being 1 and a possible defect set with the correlation being 0.5 from the one-pole one-gear ID set of the contact network; s4, rechecking the catenary equipment corresponding to the confirmed defect set and the possible defect set, and confirming the catenary equipment with an actual fault; and S5, determining an operation and maintenance ID according to the one-pole and one-gear ID of the contact network corresponding to the actual fault contact network equipment. According to the method, design, operation and maintenance and management experience correspond to defect retrieval by utilizing a defect matrix.

Description

technical field [0001] The invention belongs to the technical field of comprehensive maintenance and management of rail transit catenary systems, in particular to a method for retrieving defects of rail transit catenary systems. Background technique [0002] Based on the rapid development and high operation quality of urban rail transit, higher requirements are put forward for the safe operation of railway traction power supply equipment. In order to ensure the operation order of high-speed railways and improve the safety and reliability of power supply, the urban rail transit and high-speed railway power supply safety detection and monitoring system (6C), fault prediction and health management system (PHM), which are being promoted in depth, have contact with the distribution along the line. Coverage of all-round comprehensive monitoring and detection of network equipment, the detection and monitoring objects are abnormal key characteristic values ​​of the catenary system (...
