Abstract

The invention provides an overhead line system hard spot detection method and system; the system comprises a laser, an industrial area-array camera and a pantograph slide plate, the laser and the industrial area-array camera are arranged on the side surface of the pantograph slide plate; and the method comprises the following steps: fixedly emitting laser to the pantograph slide plate through thelaser; determining position information of a laser point on the side surface of the pantograph slide plate; acquiring a monitoring image monitored by the pantograph slide plate through the industrialarea-array camera when the laser emits laser to the fixed point of the pantograph slide plate; determining a displacement distance set of the laser points according to the monitoring image; comparingthe displacement distances in the displacement distance set with a preset distance threshold, and determining corresponding laser points when the displacement distances are not smaller than the presetdistance; and determining an overhead line system hard point according to the laser point, and determining the specific position of the overhead line system hard point according to the overhead linesystem hard point. Accurate detection of the hard points of the overhead line system can be realized.

Description

technical field [0001] The invention relates to the field of railway catenary detection, in particular to a method and system for detecting hard points of a catenary. Background technique [0002] At present, manual inspection is mainly used for the detection of the slide plate structure, by visually observing the defects on the surface of the carbon slider structure, or by using a contact measurement method, installing a pressure sensor and an acceleration sensor on the pantograph head, by measuring the The pressure and acceleration of the bow head are used to calculate the hard point. [0003] The disadvantages of the above two methods are: [0004] 1. Manual inspection is laborious and time-consuming. The detection process needs to occupy the road, and the detection time is limited by the running time. [0005] 2. Contact measurement needs to modify the pantograph head, and install pressure sensors and acceleration sensors, etc., which may bring hidden dangers and risks...
