A vehicle limit detection method and system

Abstract

The embodiment of the invention provides train gauge detection method and system. The method comprises the steps of detecting the displacement of each detection point of a train and an inclination angle of the train when the train is placed under a simulated actual road condition; calculating the coordinate value of each detecting point in the same coordinate system by treating the displacement and the inclination angle as the parameters. With the adoption of the method and system, the dynamic gauge of the train can be detected in a test line, thus the computer based simulation experiment is saved, and the obtained data are real and reliable.

Description

Technical field [0001] The present invention relates to the field of vehicle detection, in particular to a vehicle limit detection method and system. Background technique [0002] In my country's vast geographical environment, railway transportation is the most important way for people to travel. When railway vehicles are operating, the most important thing is to be safe and reliable, and to deliver passengers safely to their destinations. In order to ensure the safe operation of railway vehicles, the limits of the vehicles must be inspected before operation or during maintenance. [0003] Locomotives and rolling stock must have a safe space for operation. Therefore, the railway stipulates outline dimensions that are not allowed to be exceeded for rolling stock and buildings and equipment close to the line, that is, the limit. It can be said that the limit is a reasonable space. The limit of rolling stock is the maximum limit of the cross section of rolling stock. Specifically,...

Problems solved by technology

[0004] The current railway vehicle limit detection on the test bench can only test the static geometric profile of the vehicle, that is, the static limit, and cannot measure the dynamic limit

This makes it impossible to conduct simulation tests on the test bench whether the state of the vehicle passing the curve satisfies the dynamic limit of the vehicle. It can only be calculated through simulation instead of the real vehicle test.
