Method and device for fully automatically and accurately monitoring changes of geometric parameters of track

Abstract

The invention discloses a method for fully automatically and accurately monitoring changes of geometric parameters of a track. The method comprises the following steps: arranging each of pairs of track monitoring points (10) on the track (1) with a certain spacing distance; transmitting the data of geometric parameter changes of the track, collected from the monitoring points, to an indoor control machine through a horizontal displacement sensor (4) and a vertical displacement sensor (5); displaying the parameter changes of the track in the form of a real-time deformation curve diagram on a screen through data acquisition and processing software, and automatically storing the collected data in a database. Compared with the conventional track detection method, the method disclosed by the invention achieves the purpose of unmanned and full-automatic monitoring of railroad track parameters, prevents workers from performing measurement on the track frequently to reduce the potential personal safety hazard and eliminate the occurrence of safety accidents, has the advantages of all-weather operation, full-automatic operation, high intelligent level and high precision, improves the railroad construction environment and line monitoring level, reduces the labor intensity, increases the work efficiency, and achieves the effect of remotely monitoring the changes of geometric parameters of railroad tracks.

Description

technical field [0001] The invention belongs to the technical field of track measurement, and mainly relates to a method and a device for fully automatic and precise monitoring of changes in track geometric parameters. Background technique [0002] The track is the infrastructure of railway running, which directly bears the pressure, shock and vibration from the rolling stock and transmits it to the sleepers. Due to the interaction between the train and the track, it will inevitably cause constant changes in the track geometry. This change is the track geometry irregularity, which in turn will affect the comfort and safety of the train's fast running. Therefore, it is necessary to monitor changes in track geometric parameters at any time, and the geometric parameters to measure track smoothness mainly include: gauge, track direction, height, superelevation, twist, etc. At present, for the monitoring of geometric parameters of track smoothness, ordinary ballasted tracks are ...

Problems solved by technology

[0003] However, when the overhead reinforcement construction of the railway line is required, the traditional manual inspection includes mechanical, electronic circuit inspection instruments and other detection methods, which can only record and analyze the line condition during the inspection. If it is necessary to meet the train inspection requirements, A large number of human resources are required, and the addition of human factors will inevitably cause uncertainty in the inspection results and increase the unsafety of online operations; while for high-speed rail, intelligent total stations and track inspection trolleys are used to measure and calculate , although the purpose of monitoring can be achieved, it is time-consuming, labor-intensive, and requires high working hours, so it cannot achieve all-weather, fully automatic detection
