Problems solved by technology

[0007] The purpose of the present invention is to provide a dynamic tracking system for rigid overhead contact wires based on motion modules to solve the problem that the important characteristic information of the busbar will be lost when the pull-out value of the contact wire changes greatly. Occlusion, the problem that the contour image of the contact line cannot be obtained accurately

Embodiment

[0030] As introduced in the background technology, the existing line array camera is difficult to solve the problem of eccentric wear, and the possibility of eccentric wear in the main line is very large, and the vibration of the vehicle body will cause the coordinate system to change. If it is not strictly calibrated, the calculation accuracy will be very low. Difficult to guarantee. The disadvantage of the structured light scheme is that due to the "zigzag" change of the wire, the wire will move to the edge of the camera's field of view, which will cause the image to lose important feature information. After the comparison of the schemes, we are inclined to the structured light scheme, but the problem of occlusion of the field of view needs to be solved. The main reason for the occlusion of the field of view is that the wire and the busbar have a certain height difference, so when the contact line moves out of a certain range, the problem of occlusion of the field of view wi...

Abstract

The invention provides a motion module-based rigid overhead contact line dynamically tracking system. The motion module-based rigid overhead contact line dynamically tracking system comprises a structural light module, a motion module and a controller, wherein the motion module comprises a slider, and the structural light module is arranged on the slider; when the structural light module collectsa next frame of data, the controller predicts the position of the slider of a next moment through information of a last moment and controls the slider to move to further move the structural light module to a corresponding position. The motion module-based rigid overhead contact line dynamically tracking system enhances resolving ability and meanwhile ensures collection of important data points during movement, thereby reducing costs as well as complexity.

Description

technical field [0001] The invention relates to the field of wear detection of contact wires, in particular to a dynamic tracking system for rigid overhead contact wires based on a motion module. Background technique [0002] The line inside the subway tunnel adopts an overhead rigid catenary, and its structure is as follows: figure 1 As shown, it is mainly composed of insulating support device, tunnel roof, busbar and contact wire. While the train is running, the current is taken through the sliding contact between the pantograph slide plate and the contact wire. To make the pantograph receive current well and ensure the smooth operation of the locomotive, it is necessary to maintain a certain pressure on the pantograph-catenary to ensure reliable contact between the pantograph slide plate and the contact wire. It will inevitably bring a certain amount of wear, and the real meaning of wear measurement lies in the measurement of abnormal wear. Because abnormal wear will a...
