Orbital transfer locomotive gauge real-time measurement system and method

Abstract

The invention provides an orbital transfer locomotive gauge real-time measurement system and method, and the method comprises the steps: carrying out the system calibration of the whole measurement system before measurement, and adjusting the movement stroke of each servo telescopic guide rail; projecting the line structured light to the surface of the locomotive body to be measured, and \ synchronously recording the advancing distance of the locomotive body to be measured by the long-distance ranging sensor; uploading a picture shot by the camera to the upper computer for image processing and data processing; integrating measurement data of all the sensors to obtain high-precision three-dimensional data of the outer contour of the locomotive body to be measured, and comparing the high-precision three-dimensional data with the gauge size to obtain a difference value, so that whether the locomotive body to be measured exceeds the gauge is judged. According to the method, leaf plate collision possibly caused by the fact that the rolling stock exceeds the gauge is avoided, the accuracy of rolling stock gauge measurement is improved, the measurement universality is relatively good, and the automation degree of the measurement system is relatively high.

Description

technical field [0001] The invention belongs to the technical field of vehicle margins, and in particular relates to a real-time measurement system and method for rail-changing locomotive margins. Background technique [0002] The locomotive gauge refers to the contour dimension line that the rolling stock is not allowed to exceed under any circumstances in order to ensure that the rolling stock does not collide with equipment or buildings near the line when the rolling stock is running normally on the railway line. my country's GB 146.1-1983 "Standard Gauge Railway Rolling Stock Gauge" defines the rolling stock gauge as a limit cross-sectional profile perpendicular to the line centerline. Limit measurement is very important for the safe operation of locomotives. Therefore, it is necessary to use limit measuring devices to measure the outer contour of rolling stock during the production process of rolling stock to meet the standard limit requirements. [0003] The widely us...

AI Technical Summary

Problems solved by technology

However, this device is only suitable for the limit detection of different vehicle models on fixed tracks, and has poor applicability in the scene of changing tracks.

This technology uses a push-type gantry for measurement, and the rack and pinion at the bottom of the gantry and the mechanical structure will accumulate errors over time

In addition, when the train is stationary, the gantry is pushed to measure the limit. This measurement scene is somewhat different from the actual use scene of the train during the dynamic running process, and the accuracy of the obtained limit contour is poor.
