Embodiment Construction

[0027] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0028] figure 1 A flow chart showing a rail flaw detection method according to an embodiment of the present disclosure, such as figure 1 As shown, the flaw detection method includes the following steps:

[0029] In step S11, a trigger signal for flaw detection on the track is received;

[0030] In step S12, control the camera installed on the automatic inspection vehicle to take pictures of the track based on the trigger signal; and

[0031] In step S13, flaw detection is carried out on the rail using images captured by the camera.

[0032] In the present disclosure, flaw detection refers to detecting whether components on the track are damaged, lost, def...

Abstract

The invention relates to a rail flaw detection method, device and system and an automatic inspection vehicle which can rapidly and accurately detect flaws of rails. The rail flaw detection method comprises the steps of receiving a trigger signal for flaw detection of a rail; controlling a camera mounted on the automatic inspection vehicle to photograph the rail based on the trigger signal; and carrying out flaw detection on the rail by utilizing an image shot by the camera.

Description

technical field [0001] The present disclosure relates to the technical field of rail transit, and in particular, to a rail flaw detection method, device, system, and automatic inspection vehicle. Background technique [0002] At present, when inspecting the track, the vibration signal of the train is first obtained, and then the impact is qualitatively identified according to the vibration signal to determine whether there is an obstacle on the track. The above scheme can only identify obstacles on the track, but cannot perform accurate track flaw detection. Contents of the invention [0003] The purpose of the present disclosure is to provide a rail flaw detection method, device, system and automatic inspection vehicle, which can quickly and accurately detect flaws on rails. [0004] According to the first embodiment of the present disclosure, there is provided a rail flaw detection method, comprising: receiving a trigger signal for flaw detection of the rail; based on t...
