Method and device for monitoring transverse displacement of track

Abstract

Disclosed are a method and a device for monitoring transverse displacement of a track. The method for monitoring the transverse displacement of the track includes the following steps: collecting and processing image data through a video collection device, and sending the image data to a communication switching device through wire communication; receiving the image data through the communication switching device, and transferring and sending the image data to a host data processing unit through wireless communication; and figuring out the offset of the transverse displacement of the track through the host data processing unit according to data comparison, wherein the host data processing unit controls operation of the whole device. The device for monitoring the transverse displacement of the track comprises the video collection device located in a monitoring spot. The image data are collected by a camera of the video collection device, processed by a micro-control unit of the video collection device, and transferred to the host data processing unit through the communication switching device; and the offset of the transverse displacement of the track is figured out according to the data comparison. According to the method and the device for monitoring the transverse displacement of the track, the image processing technique is used for measuring the transverse displacement of the track, and distance control and data access on data collection monitoring and track displacement processing are achieved. The device is reliable, stable and low in power consumption.

Description

Technical field [0001] The invention relates to a measurement technology of railway track characteristic information, in particular to a method and a device for measuring the lateral displacement of the track through image processing. Background technique [0002] my country’s railway transportation lines are divided into up-line and down-line. All vehicles must travel on a single-lane line. Over time, this driving will affect the condition of the track. In addition, the long-term exposure to environmental temperature changes will cause the rail to expand and contract. Under the influence of vehicles and the environment, railway tracks will inevitably produce lateral displacement, which will inevitably bring dangers to railway operation and personal and property safety. Therefore, the measurement of the lateral displacement of the track has become an indispensable and important link in daily maintenance of the track. [0003] At present, optical technology is mostly used in the mar...

AI Technical Summary

Problems solved by technology

[0003] At present, optical technology is mostly used in the market. For example, the lateral displacement of the rail is measured by emitting a beam of light from a laser. Now the grating line displacement measurement method is commonly used, but the composition of this grating line displacement measurement device is relatively complicated. It requires each fastening All parts should be firm and reliable, and all moving parts should be flexible and stable, without blockage and without looseness. Once a certain part of the system device is loose or blocked, the measurement results will be unreliable, and the device for grating line displacement measurement relatively large power consumption
