[0003] Traditional track laying uses a combination of manpower and machinery to lay steel rails on the track section by section. This construction method requires a lot of manpower and material resources, and is easily affected by the weather environment. The control of the construction period is not ideal.
However, if a fully mechanical operation is adopted, it is necessary to control the corresponding device to accurately grab the rail and put the rail into the track groove accurately according to the construction plan, and how to control the corresponding device to automatically and intelligently transport the rail from the rail transport device Put it into the track groove, it is not very perfect in the prior art

Embodiment 1
[0056] In order to realize the mechanical intelligent rail laying and ensure the standardization of rail laying, the present invention proposes an automatic control method for rail laying, which includes a rail pushing device, a guide frame, a guide groove, a manipulator and a main control unit, and The rail pushing device, the guide frame and the guide groove are equipped with laser scanners, and the main control unit includes steps for laying the rails:
[0057] S1: Obtain rail image feature information according to the preset rail image;
[0058] S2: Obtain the first scanning data of the rail of the laserscanner at the rail pushing device, and extract the clamping feature points in combination with the rail image feature information;
[0059] S3: Control the rail pushing device to grab the rail according to the gripping feature point;
[0060] S4: Obtain the second scanning data of the rail of the laserscanner at the pedestal, and extract the first end feature point of t...

Abstract
The invention discloses an automatic controlsystem and method for rail laying, which relates to the field of rail transit, and is mainly divided into a rail grabbing stage, a rail pushing stage, and a rail entering groove stage, and is obtained by using camera calibration technology in the three stages Rail feature point information, so as to locate the coordinates of the rail, and judge the position according to the coordinates, so as to accurately control the rail pushing device to push the rail, and control the manipulator to grab the rail into the groove. The invention adopts the camera calibration to locate the rail, and the coordinates of the camera itself can be used as the base point without being affected by the rail itself and the surrounding environment. Accurate coordinate information can be obtained quickly and efficiently, and the operation efficiency of rail laying is greatly improved.
Description
technical field [0001] The invention relates to the field of rail transportation, in particular to an automatic control method and system for rail laying. Background technique [0002] In recent years, the construction of my country's intercity rail transit and inter-provincial rail transit has entered a stage of rapid development. In order to ensure the long-lasting, stable and high ride comfort of rail projects, the construction standards of rails are getting higher and higher, the construction technology requirements are updated quickly, and construction management Getting stricter. [0003] Traditional track laying uses a combination of manpower and machinery to lay steel rails on the track section by section. This construction method requires a lot of manpower and material resources, and is easily affected by the weather environment. The control of the construction period is not ideal. . However, if a fully mechanical operation is adopted, it is necessary to control th...
