Abstract

The invention provides a method of adopting a laser measurement technique to measure the longitudinal displacement of railway tracks, which mainly relates to the measurement of railway maintenance departments for the longitudinal displacement of tracks. The method is characterized by utilizing a corresponding control strategy to measure the displacement of the railway tracks after a control system detects and receives a light source emitted by a laser emitter through a laser detector. The method overcomes the characteristics that the prior measurement equipment is great in centering and collimation difficulty, troublesome to adjust and susceptible to human and environmental factors, and the like, adopts laser collimation properties, utilizes the laser detector, capacitive-gate ruler positioning and other measurement modes, automatically acquires data signals through the embedded control strategy and calculation methods of a micro-processing controller, works out the longitudinal offset displacement of the tracks, and is an relatively ideal laser measurement instrument for the longitudinal displacement of the railway tracks at present. The method has the advantages of simple operation, convenient detection, visual clear display, high measurement precision and the like.

Description

technical field [0001] The invention relates to the measurement of the longitudinal displacement of the rail by the railway engineering department, and mainly adopts the laser measurement technology to realize the method for measuring the longitudinal displacement of the railway rail. Background technique [0002] With the continuous improvement of the national economy, in order to meet the needs of the transportation market and improve the competitiveness of railway transportation in the transportation market, railway transportation is constantly developing in the direction of high speed and heavy load. However, my country's railway lines are developed under the condition of mixed loads of passengers and goods. Due to the inherent characteristics of seamless lines, their daily maintenance is quite different from that of ordinary lines. The railway engineering department must accurately handle various basic technical parameters in order to ensure the safety of the line. [...
