Railway locomotive running attitude measuring method

Abstract

The invention relates to a railway locomotive running attitude measuring method comprising the following steps: a high-speed camera is fixedly arranged on at least three non-colinear points of the railway locomotive under measurement by taking surfaces of rails as the measuring datum; along with the running of the railway locomotive under measurement, the high-speed camera shoots the running imagesequence of an counterpart camera arranged on the top surface of the rails; the running image sequence of the counterpart camera is processed and analyzed, and the offset of each point relative to the rails is obtained; the special attitude and the offset of the railway locomotive under measurement relative to the two rails are determined according to the offset of three measuring points, and accordingly the dynamic offset of any point which is fixedly connected with the railway locomotive under measurement is obtained; the dynamic envelop curve of the railway locomotive under measurement isobtained according to the dynamic offset of the key point on the profile of the railway locomotive under measurement; the dynamic envelop curve is compared with the building profile, and the ultralimit early warning and alarming is carried out if a monitoring point is close to or exceeds the building clearance. The invention ensures the railway locomotive running attitude measuring precision whenthe dynamic displacement of the railway locomotive is measured on line in real time.

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 method. 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
