Embodiment Construction

[0075] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, so they are only examples, and should not be used to limit the protection scope of the present invention.

[0076] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the usual meanings understood by those skilled in the art to which the present invention belongs.

[0077] First, let’s introduce the definition of the orbital geometric state parameters involved in this implementation:

[0078] Gauge refers to the minimum distance between the active sides of two strands of rail at 16 mm below the top surface of the rail. Since the contact between the wheel rim and the side of the rail is 10-16mm below the top surface of the rail, and the gaug...

Abstract

The invention relates to a real-time monitoring method and system of high-speed railway track geometry. The system includes a plurality of prisms, and each prism is arranged on the waist of the trackaccording to a certain interval; a data acquisition unit which is arranged outside the driving area, and the data acquisition unit is used for launching electromagnetic wave by scanning to the prismsarranged on the waist of the track, then the electromagnetic wave reflected by the prisms is received to obtain the real-time spatial coordinates of each prism; a data processing unit which is connected with the data output end of the data acquisition unit, and the data processing unit is used for obtaining the real-time spatial coordinates obtained from the data acquisition unit, then current geometric state parameters of the track are obtained by the specific algorithm in this paper according to the real-time spatial coordinates and the initial space coordinate of the prisms. The real-time automatic monitoring system for the track geometry based on an automatic total station is established through arranging the appropriative prisms on the track to ensure the operation safety of the high-speed railway.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to a method and system for real-time monitoring of the geometric state of a high-speed railway track. Background technique [0002] During the operation of the high-speed railway, due to the influence of unfavorable natural conditions, the pressure of the train load, the regional settlement of the foundation and roadbed, and the construction of railway-related projects, the track geometry changes caused by the deformation of the high-speed railway subgrade, such deformation will make the track exist. Various potential safety hazards, and the detection of the geometric state of the track can detect this deformation in time, and then a series of track maintenance can eliminate these potential safety hazards. At present, manual measurement is mainly used to monitor the geometric state of existing railway tracks. For high-speed railways, due to the characteristics of fast drivi...
