Railway locomotive and vehicle operating attitude measurement system

Abstract

A railway locomotive and vehicle operating attitude measurement system comprises a group of high-speed video cameras which are installed on at least three non-colinear points of a tested vehicle body, arranged oppositely to a running track of the tested vehicle body and used for shooting a track image sequence when a train runs, and an imagine acquisition and processing module used for receiving the track image sequence and analyzing the track image sequence obtained by the high-speed video camera on each point so as to obtain offset of each point relative to the track and determine a spatial attitude and the offset of the tested vehicle relative to two tracks. The railway locomotive and vehicle operating attitude measurement system takes rail surface and track center line as a benchmark, and is non-contact and based on machine vision, can conduct real-time measurement to the dynamic offset of the locative and vehicle to obtain the dynamic offset of an optional position on the vehicle body relative to track surface coordinates, conduct online measurement to the vehicle dynamic displacement in real time, conduct early warning and alarm to overrunning, and simultaneously ensure the measurement accuracy.

Description

technical field [0001] The invention belongs to the offset test and measurement technology caused by various vibration forms of locomotives and vehicles when the train is running, and specifically relates to a measurement of the running attitude of railway locomotives and vehicles that can detect the dynamic envelope of locomotives and carry out over-limit warning or alarm system. Background technique [0002] Under the premise of ensuring the safety of railway operation, to rationally use the limited space to transport over-limited goods, it is necessary to formulate operating conditions for over-limited trains that meet the current actual situation, including the operating conditions for over-limited trains passing through buildings or equipment and the relationship between over-limited trains and trains on adjacent lines. Operating conditions at rendezvous. And it depends on the distance between the overrunning train and the building limit and the distance between the ov...

AI Technical Summary

Problems solved by technology

At present, various railway freight car loading overrun detection devices or lateral offset detection devices developed at home and abroad can only detect the overrun situation of rolling stock (loaded goods) statically or when passing a fixed point, and cannot be carried out in real time according to the movement of the rolling stock. Monitor its running posture
