Abstract

The invention discloses a non-contact pantograph-catenary contact force detection method based on an image processing technology, and compared with a traditional detection method, the method is simple in equipment installation, has the characteristics of real-time performance and non-contact performance, can avoid the transformation of a pantograph head during detection, and guarantees the original dynamic performance of the pantograph head. Meanwhile, more automation and intelligence are achieved, the detection flexibility is high, and the accuracy is high; moreover, the system is small in driving interference, and is suitable for long-distance and long-time continuous tracking detection under severe environment conditions. Through multiple groups of ground dynamic experiments, the effectiveness and accuracy of the method are verified, the detection precision after the inertia force and the damping force are corrected can greatly meet the detection precision of the pantograph-catenary contact force, the research on the pantograph-catenary contact force detection method in the non-contact measurement field at present is further enriched, and the detection accuracy of the pantograph-catenary contact force detection method is improved. And meanwhile, accurate contact force data can be provided for evaluation of pantograph-catenary current collection quality and real-time fault monitoring.

Description

technical field [0001] The present invention relates to, in particular to a non-contact pantograph-catenary contact force detection method based on image processing technology. Background technique [0002] With the vigorous development of my country's rail transit field, there are more and more rail transit trains in daily operation, so the status detection of the pantograph-catenary system of rail trains is becoming more and more important. The catenary and pantograph are important components in the electrified railway power supply system, and the dynamic contact between the pantograph and catenary is the key condition to ensure the good current flow of the electric locomotive. a key. Its basic work is to perform real-time, efficient and accurate detection of the pantograph-catenary system. As a direct reflection of the current quality of the pantograph-catenary system, the dynamic contact force between the catenary and the pantograph is the most important thing in the d...
