SYSTEM AND METHOD FOR MEASURING THE POSITION OF THE CONTACT WIRE OF AN OVERHEAD POWER LINE RELATIVE TO A RAILWAY TRACK

摘要

The invention relates to a system for measuring the position of the contact wire of an overhead power line, comprising a first measurement means including a vertical rangefinder capable of measuring the height of the contact wire and a second measurement means capable of measuring the offset of the contact wire. The system also comprises at least one first inclinometer that enables the inclination of the mounting of the system positioned on the rails to be measured, and a camera pointing upward and capable of capturing the image of the contact wire, and the second measurement means comprises a second inclinometer secured to the laser rangefinder, which is mounted on a motor-driven lateral-inclination pivot, and which is capable of measuring the angle of the beam thereof relative to the vertical when aimed at the contact wire.

1. A system for measuring the position of a contact wire of a power supply catenary relative to a railway track comprising a first measurement means comprising a vertical range finder capable of measuring a height of the contact wire relative to rails of the railway track, and second measuring means capable of measuring an offset of the contract wire relative to a vertical median plane of said rails and comprising an inclinometer secured to the vertical range finder mounted on a lateral inclination pivot and capable of measuring its beam angle when it points to the contact wire; all of these measuring means are arranged on a support placed on the rails, wherein the system further comprises at least another inclinometer that permits measuring inclinations of the system support relative to the horizontal and a camera pointed upward in the same direction as the axis of the track and capable of capturing the image of the contact wire, and wherein the inclination pivot of the vertical range finder is motor-driven.
