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

Embodiment Construction

[0020] The method of the present invention for monitoring the lateral displacement of the rail is to adopt image processing technology, realize the remote control and data access of the image data of the rail displacement through the on-site acquisition and processing, through the serial port conversion device, and obtain the reliable lateral displacement offset of the rail.

[0021] In order to implement the method for monitoring the lateral displacement of the track of the present invention, the device used includes a video capture device, a communication switching device and an upper data processing unit. See figure 1 , There is at least one track mark 5 on the waist of the tested railway rail 4, which is laid along the track line according to the selected distance. The laying spacing of the track marking 5 is determined according to the local track conditions. If the track section with frequent problems is laid, the laying interval is slightly smaller, and if the track section...

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...
