Embodiment 1

[0062] as attached figure 1 As shown, a specific embodiment of the fast track change operation sleeper bolt position detection system based on the method of the present invention includes:

[0063] An image acquisition module 1, configured to acquire image data of sleeper bolts 40;

[0064] The image processing module 2 processes the image data of the sleeper bolts 40 acquired by the image acquisition module 1. When the sleeper bolts 40 are calculated relative to the initial calibration state (the laser beam emitted by the line light source 11 under the initial centering state of the rail changing car 10 The center of the line roughly coincides with the center of the sleeper bolt 40 located on the outside of the rail 50, so that the laser line can be irradiated on the sleeper bolt 40 located on the outside of the rail 50. This state is called the initial calibration state) When lateral deviation occurs, a control is issued. Working offset data of clamp 30 moving direction and...

Embodiment 2

[0080] A specific embodiment of a method for detecting the position of sleeper bolts in rapid rail change operation, comprising the following steps:

[0081] S10) acquiring the image data of the sleeper bolts 40;

[0082] S20) Process the acquired image data of the sleeper bolts 40, and when it is calculated that the sleeper bolts 40 have laterally shifted relative to the initial calibration state, then send out operation offset data for controlling the movement direction and displacement of the clamp 30;

[0083]S30) Control the movement of the clamp 30 according to the operation offset data sent by the image processing module 2, so as to maintain the relative positional relationship between the clamp 30 and the sleeper bolt 40.

[0084] Step S20) further includes the following process:

[0085] S21) Carry out parameter calibration of the camera 13, and laser plane calibration issued by the line light source 11;

[0086] S22) Setting the threshold information involved in ju...

Abstract

The invention discloses a sleeper bolt position detection method for fast rail replacement. The sleeper bolt position detection method for fast rail changing comprises steps of S10 obtaining image data of sleeper bolts, S20, performing processing on obtained image data of the sleeper bolts, emitting operation offset data of a moving direction and a displacement of a controlled clamp when a transverse offset of the sleeper bolt relative to an initial calibrated state is calculated, and S30, controlling a clamp to move according to operation displacement data emitted by an image processing module in order to maintain a relative position relation between the clamp and the sleeper bolt. The sleeper bolt position detection method for fast rail changing solve problems that the current sleeper bolt detection mode does not realize automation, the efficiency is low, safety hazards are big, misjudgment and misoperation happen, sleeper bolts can be damaged and a rail replacement process is interrupted.

Description

technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to an image-recognition-based sleeper bolt position detection method applied to rail engineering vehicles, especially fast track-changing vehicles. Background technique [0002] In developed countries, mechanized operations are mostly used for railway track changing operations. However, the current methods of track changing operations in my country mainly use simple machines or refitted vehicles, which have poor construction safety, complicated construction organization, and low efficiency of track changing operations. In China, the annual track-changing operation volume of the whole road reaches tens of thousands of kilometers, and the construction task is very heavy. In order to improve the efficiency and meet the requirements of the track changing task, a special machine for replacing the seamless line - the fast track changing operation vehicle was born as nee...
