Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0049] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a track deformation measuring method and device based on a fiber bragg grating, and the track deformation measuring method based on the fiber bragg grating comprises the following steps: collecting first liquid level information of a communicating vessel structure in an initial state; collecting second liquid level information of the communicating vessel structure in the sedimentation state; analyzing and comparng the first liquid level information and the second liquid level information, and obtianing the non-uniform settlement value of the track; and controlling the fiber bragg grating sensing device to collect temperature information of the communicating vessel structure, and correcting the non-uniform settlement value of the track according to the temperature information. The track deformation measuring method and device based on the fiber bragg grating aims to solve the problem of poor measurement precision of non-uniform settlement of the track in the prior art.

Description

technical field [0001] The invention relates to the technical field of rail deformation measurement, in particular to a method for measuring rail deformation based on an optical fiber grating and a device for measuring rail deformation based on an optical fiber grating. Background technique [0002] Urban rail transit is a vehicle transportation system that uses rail structures for load-bearing and guidance. According to the requirements of the overall planning of urban transportation, fully enclosed or partially enclosed special rail lines are set up to transport a considerable amount of passenger traffic in the form of trains or bicycles. , urban rail transit is an important symbol of urban progress. However, after the track structure is completed and put into use, as the rail traffic continues to function, the track will have a certain amount of uneven settlement. At this time, it is necessary to accurately measure the uneven settlement of the track for subsequent process...
