Problems solved by technology

This method of manual fixed-point measurement generally has shortcomings such as discontinuous measurement values ​​and low measurement efficiency.
Therefore, in the face of today's increasingly high safety requirements for electrified railways, the traditional manual fixed-point detection technology has large detection errors, discontinuous detection waveforms, and low efficiency. Imported components, the overall cost of the system is expensive; therefore, there is an urgent need for a fast, continuous, energy-saving, and cost-effective catenary geometric parameter detection system

Abstract

The invention discloses a portable overhead line geometric parameters detection method and a portable overhead line geometric parameters detection system based on a binocular linear array CCD camera. The method includes the steps of: 1, disposing two imaging devices on two tracks, disposing a line light source at the center between the two imaging devices; 2, transmitting linear illuminating light towards the overhead line, wherein generated reflected light respectively enter the two imaging devices for imaging; 3, calculating the geometric parameters of the overhead line. The system is used for implementing the above method. The portable overhead line geometric parameters detection system has the advantages of being simple in structure, convenient to operate and carry and capable of working all the time.

Description

technical field [0001] The invention mainly relates to a railway catenary detection system, in particular to a portable catenary geometric parameter detection method and system based on a binocular linear array CCD camera. Background technique [0002] At present, when testing railway catenary, the measurement of conventional geometric parameters such as catenary height, pull-out value, and side limit is mostly carried out by manual fixed-point measurement. This method of manual fixed-point measurement generally has shortcomings such as discontinuous measurement values ​​and low measurement efficiency. Therefore, in the face of today's increasingly high safety requirements for electrified railways, the traditional manual fixed-point detection technology has large detection errors, discontinuous detection waveforms, and low efficiency. Imported components, the overall cost of the system is expensive; therefore, there is an urgent need for a fast, continuous, energy-saving, a...
