Problems solved by technology

When the expansion of the track slab reaches more than 3mm due to high temperature, and the height or direction deviation of the line exceeds 3mm, it should be rectified in time to avoid hidden dangers of driving safety; Manual measurement and verification of parameters such as the displacement of the track slab, the size and deformation of the joint between the transition plate and the support layer, the relative displacement of the transition plate and the track slab, and the relative displacement of the support layer and the track slab, this method is time-consuming, laborious, and highly subjective. Moreover, most of the recorded data are paper-based and fragmented, which is not conducive to data sorting and subsequent analysis throughout the life cyc...

Embodiment Construction

[0060] The technical solution of the present invention will be explained more clearly and completely through the description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0061] like figure 1 As shown, a multi-dimensional intelligent monitoring system for railway track and track slab status according to the preferred embodiment of the present invention includes: a measurement component 1 , a control component, a communication component 3 , and a power supply component 4 .

[0062] The measurement component 1 includes an infrared temperature measuring device, a laser distance measuring device, an image sensor and a near-infrared supplementary light. Infrared temperature measuring equipment measures the surface temperature of rails and track slabs, which control the angle through a rotating mechanism. The laser ranging equipment measures the distance of the rail and converts it into the change of the eccentric state of the ra...

Abstract

The invention provides a railway track and track plate state multi-dimensional intelligent monitoring method and a system, and the monitoring method comprises the steps: S1, enabling the multi-dimensional intelligent monitoring system to obtain the surface temperature of a track and a track plate, measuring the distance between the track and the track plate, converting the distance into the eccentric distance of the track, and obtaining an observation image; S2, transmiting the surface temperature and the rail eccentric distance to a control module, transmiting an observed image to a processing module, and combining the processing module with a deep learning network and a visual detection technology to calculate rail plate displacement and rail creeping; S3, packaging the surface temperature, the rail eccentric distance, the rail plate displacement and the rail creeping measurement result and transmiting to a management center; and S4, performing temperature and displacement situationanalysis on each monitoring point by the management center, and pushing abnormal displacement alarm of the railway track and the track plate. According to the multi-dimensional intelligent monitoringmethod and the system, comprehensive, long-term and intelligent monitoring of the railway track and track plate states is achieved, and the safety of railway operation is improved.

Description

technical field [0001] The invention relates to a method and system for multi-dimensional intelligent monitoring of railway tracks and track slab states, belonging to the field of safety monitoring of railway tracks and track slabs. Background technique [0002] Under loads such as temperature, train braking, and concrete shrinkage, railway tracks and track slabs bear complex lateral and longitudinal forces. When the expansion of the track slab reaches more than 3mm due to high temperature, and the height or direction deviation of the line exceeds 3mm, it should be rectified in time to avoid hidden dangers of driving safety; Manual measurement and verification of parameters such as the displacement of the track slab, the size and deformation of the joint between the transition plate and the support layer, the relative displacement of the transition plate and the track slab, and the relative displacement of the support layer and the track slab, this method is time-consuming, ...
