Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0031] like figure 1 As shown, the catenary tracking method in the pantograph-catenary system of this embodiment includes the following steps: S1. Obtain the video frame image of the pantograph-catenary system; S2. Determine the position information of the pantograph through image recognition; S3. Identify the pantograph in the image Calculate and determine the parameters of the catenary; S4. Calculate and determine the contact line according to the parameters of the catenary and the position information of the pantograph. In this embodiment, if the obtained video frame image is a color image, processing the color image into a grayscale image is also included.

[0032] In this embodiment, step S2 specifically includes: performing matching through a preset panto...

Abstract

The invention discloses a catenary tracking method and system in a pantograph catenary system. The catenary tracking method comprises the following steps: S1, acquiring a video frame image of the pantograph catenary system; S2, determining position information of the pantograph through image recognition; S3, identifying all suspension lines in the image, and calculating and determining parametersof the suspension lines; And S4, calculating and determining the contact line according to the parameters of the suspension line and the position information of the pantograph. The method has the advantages that the contact line can be identified from multiple suspension lines and tracked, line changing identification and processing of the contact line can be carried out at the anchor section joint, the accuracy is high, and the stability is good.

Description

technical field [0001] The invention relates to the technical field of train catenary monitoring, in particular to a catenary tracking method and system in a pantograph-catenary system. Background technique [0002] Electrified railway is the trend of railway development now. Electrified locomotives mainly use catenary pantographs to obtain electricity through contact. The geometric parameters (conduction height, pull-out value) of the catenary are important factors for the stable power supply of electrified railways. At present, it is a main solution of non-contact measurement to photograph catenary pantograph through infrared image processing, so as to calculate its conductance pull-out value. In infrared image processing, the matching method is generally used to match the position of the pantograph. However, the position of the contact line needs to be selected from multiple suspension lines. At the joint of the anchor section, the judgment of changing the line is also ...
