Problems solved by technology

[0002] In rail transportation, due to the operation of vehicles, natural disasters, track vibration and wear, and changes in subgrade settlement, changes in the relative distance between tracks, changes in plane height, changes in track fastening facilities, and cracks and deformations inside the track will occur. These changing factors will bring harm to the safety of rail transportation. At present, manual on-site testing is used to understand the state of the track, or testing is carried out through test vehicles during operation. This will cause poor real-time monitoring and sudden changes in track parameters. Defects that cannot be discovered and alarmed in time, and the workload and cost of testing are large

Embodiment Construction

[0010] The embodiments of the present invention are described below by taking the drawings as an example.

[0011] figure 1 Shows the composition diagram of the track online monitoring system of an embodiment of the present invention, including the composition diagram of the track online monitoring system at a track test point, in which:

[0012] (1) and (2) are displacement sensors, and ordinary displacement sensors can be used; (3) and (4) are vibration sensors, and the working vibration spectrum can be used to effectively adapt to the track vibration spectrum; the displacement sensor and vibration sensor are set in (5) and (6) are laser distance detectors, which can be used to measure the tiny variables of the track. The laser distance detectors are set on both sides of the track. The height is based on the laser beam scanning to the outer edge of the track, and a combination of multiple laser distance detectors is used to scan and measure the distance to the outer edge of the ...

Abstract

The invention discloses a track on-line monitoring method and a track on-line monitoring system which are realized by a communication system, a computer system, a displacement sensor, a vibration sensor, a laser distance probe, a microprocessor and a communication module. The change of relative space of the tracks, the change of plane height, the change of a track fastening facility and cracking and deformation of the interiors of the tracks are monitored on line, thereby the invention has the characteristics of good real-time performance in monitoring, in-time discovery and alarming of abrupt track parameter change, low measurement workload and low cost.

Description

Technical field [0001] The invention is a track online monitoring method and a track online testing system, and belongs to the technical field of track transportation. Background technique [0002] In rail transportation, due to the operation of vehicles, natural disasters, track vibration and wear, and changes in the settlement of roadbeds, changes in the relative distance of the track, changes in plane height, changes in track fastening facilities, and cracks and deformations inside the track will occur. These change factors can bring harm to the safety of rail transportation. At present, manual field testing is used to understand the status of the track, or the test vehicle is tested in operation. This will cause poor real-time monitoring and prevent sudden track parameter changes. Failure to detect and report to the police in time, test workload and high cost defects. Summary of the invention [0003] In view of the above reasons, the purpose of the present invention is to pr...
