Turnout and track full-profile wear vision measurement instrument and measurement method thereof

Abstract

The invention provides a turnout and track full-profile wear vision measurement instrument and a measurement method thereof. The turnout and track full-profile wear amount can be measured, and the whole-section turnout and steel track wear is analyzed; the measurement instrument comprises a hardware measurement system and measurement data analysis and processing software, the hardware measurementsystem comprises a laser vision measurement and acquisition device, a rotary encoder measurement and positioning device and a data transmission and power supply device, the measurement data analysis and processing software comprises a laser vision measurement and acquisition device calibration module, a laser vision measurement and acquisition device control module, a data acquisition image processing module, a measurement data synthesis module and a measurement data analysis module, and the software can be installed on a PC. The measurement instrument can achieve non-contact and automatic measurement, and the problems of large measurement time consumption and low efficiency of mechanical measurement tools are solved; meanwhile, the measurement instrument has high measurement precision, the measurement efficiency is greatly improved, and the digital management of railway maintenance is facilitated.

Description

technical field [0001] The invention belongs to the field of on-site safety detection and machine vision measurement of railways, in particular to a visual measuring instrument for full-profile wear of a turnout and a track and a method for visually measuring the full-profile wear of a turnout and a track by using the measuring instrument. Background technique [0002] my country's high-speed railway has become a pillar industry that promotes the development of the national economy and technology, and promotes the rapid development of cities. Nowadays, locomotives are running faster and faster, and the allowable wear and deformation of turnouts and rail components exposed to the wild environment are higher, otherwise serious accidents such as train derailment will occur. In order to ensure the safety of train operation, it is necessary to know the running status of rails, turnouts and other railway components in a timely manner and accurately detect their damage, establish a...

Problems solved by technology

Although the principle of traditional contact measurement tools is simple and easy to understand and master, the measurement accuracy and efficiency will be greatly affected due to the inherent errors and reading errors of the measuring tools, as well as the influence of various factors such as the working experience, physical condition, and mental condition of the inspectors. At the same time, the detection data is not convenient for data management and retrospective analysis
