Embodiment 1

[0028] This embodiment provides a track plate based on distributed optical fiber monitoring;

[0029] Such as Figure 1-Figure 3 As shown, in the track plate based on distributed optical fiber monitoring in this embodiment, several distributed optical fibers 2 are buried inside the track plate 1 , and optical fiber connectors 3 are provided at both ends of each distributed optical fiber 2 .

[0030] The present invention embeds several distributed optical fibers inside the track slab, and each distributed optical fiber is provided with an optical fiber connector at both ends, and is connected with a measuring device to form a measurement loop during use, which can measure the internal stress, strain, temperature and cracks of the track slab, etc. data, and by using the transmission efficiency of optical fiber, various parameters during the operation of the track slab can be collected in real time. After big data analysis, it can provide real-time monitoring of the use status o...

Embodiment 2

[0038] Such as Figure 4 As shown, a track structure includes laying several track slabs 1 described in Embodiment 1 along the line, and the distributed optical fibers 2 in adjacent track slabs 1 are correspondingly connected in series by connecting optical fibers 5, and the connecting optical fibers 5 and The optical fiber connectors 3 at the ends of the distributed optical fibers 2 are connected.

[0039] In the present invention, by correspondingly connecting the distributed optical fibers in adjacent track plates through connecting optical fibers, a closed-loop track plate distributed optical fiber monitoring circuit laid along the line can be formed, so as to monitor the internal stress, strain, temperature and temperature of the track plate in real time. Cracks and other data collection, the track structure can greatly improve the operation data collection ability of the ballastless track structure, and provide great help for the realization of railway track system infor...

Description

technical field [0001] The invention relates to the field of track engineering, in particular to a track plate based on distributed optical fiber monitoring. Background technique [0002] Track engineering is an engineering structure that provides direct support and guidance for trains. Its stability and smoothness directly affect the safety and comfort of trains. Therefore, the monitoring of track engineering structures is very meaningful and valuable. The track engineering structure is generally divided into two categories: ballasted track and ballastless track. The ballasted track is generally composed of steel rails, fastening systems for buckling and fixing the rails, sleepers for supporting and fixing the fasteners, and ballast bed structures for supporting and wrapping the sleepers from top to bottom. The ballastless track is generally composed of steel rails, fastener systems, sleepers, reinforced concrete track bed slabs and bases and other substructures from top t...
