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] Embodiments of the present invention will be described below by taking the accompanying drawings as an example.

[0011] figure 1 It shows the composition diagram of the track online monitoring system in one embodiment of the present invention, including the composition diagram of the track online monitoring system at a track test point, wherein:

[0012] (1), (2) are displacement sensors, and ordinary displacement sensors can be used; (3), (4) are vibration sensors, and its working vibration spectrum can effectively adapt to the track vibration spectrum; the displacement sensor and vibration sensor are set at The side of the track is in contact with the track; (5) and (6) are laser distance detectors, and the test accuracy can meet the measurement of the tiny variables of the track. The laser distance detectors are set on both sides of the track, and the distance and The height is subject to the outer edge of the track that can be scanned by laser rays, and a combinat...

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 relates to an online track monitoring method, which 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 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. Contents of the invention [0003] In view of the above reasons, the object of the present in...
