Abstract
1. Способ измерения износа проводов контактной сети электрифицированных железных дорог, заключающийся в подсвечивании проводов лазерным веерным излучателем, приеме телевизионной камерой отраженного сигнала и фиксировании его в виде линии пересечения плоскости веерного луча с поверхностью провода, передаче полученного изображения в компьютерный блок обработки сигнала и вычислении степени износа контактного провода, отличающийся тем, что подсвечивание контактного провода осуществляют двумя лазерными веерными излучателями, диаграммы направленности которых сведены в параллельные плоскости, расположенными симметрично по обе стороны оптической оси приемной телевизионной камеры, фиксируют телевизионной камерой линии пересечения поверхности провода и плоскостей веерных лучей, и по форме линий пересечения посредством компьютера вычисляют степень износа контактного провода, для получения изображения используют диффузную составляющую отраженного сигнала, причем осветительное и приемное телевизионное оборудование располагают на отдельном измерительном полозе токоприемника на минимально допустимом фиксированном расстоянии от контактного провода. ! 2. Способ измерения по п.1, отличающийся тем, что при одновременном измерении износа проводов в количестве больше одного (2÷4), каждый провод подсвечивают двумя лазерными веерными излучателями, диаграммы направленности которых сведены в параллельные плоскости и которые располагают симметрично по обе стороны оптической оси приемной телевизионной камеры. ! 3. Способ измерения по п.1 или 2, отличающийся тем, что диффузную составляющую отраженного лазерного 1. A method of measuring the wear of wires of a contact network of an electrified railway, which consists in highlighting the wires with a laser fan, receiving a reflected signal by a television camera and fixing it in the form of a line of intersection of the plane of the fan beam with the surface of the wire, transferring the received image to a computer signal processing unit and calculating the degree contact wire wear, characterized in that the contact wire is illuminated by two laser fan emitters, diagrams The directions of which are reduced in parallel planes symmetrically located on both sides of the optical axis of the receiving television camera, the television camera fixes the lines of intersection of the wire surface and the planes of fan beams, and the degree of wear of the contact wire is calculated by computer using the shape of the intersection lines, using the diffuse component to obtain the image a reflected signal, and the lighting and receiving television equipment have a current on a separate measuring run receiver at the minimum permissible fixed distance from the contact wire. ! 2. The measurement method according to claim 1, characterized in that while measuring the wear of the wires in an amount of more than one (2 ÷ 4), each wire is illuminated by two laser fan emitters, the radiation patterns of which are arranged in parallel planes and which are placed symmetrically on both sides optical axis of the receiving television camera. ! 3. The measurement method according to claim 1 or 2, characterized in that the diffuse component of the reflected laser
