Underground pipeline safety monitoring device based on stress induction technology

Abstract

An underground pipeline safety monitoring device based on the stress induction technology comprises a Bragg fiber sensing module, a data processing module and an alarm prompting module. The data output end of the Bragg fiber sensing module is connected with the data input end of the data processing module, and the data output end of the data processing module is connected with the data input end of the alarm prompting module. According to the underground pipeline safety monitoring device, Bragg fibers and gratings are applied, the stress condition of a pipeline is judged through remote stress induction, the stress condition of the pipeline is monitored in real time, and therefore when the stress exceeds the limiting value, the device can give an alarm in time, and the disastrous accidents are avoided.

Description

Technical field [0001] The invention relates to the technical fields of optics and electronics, and in particular to a detection device for pipeline construction under urban roads based on electromagnetic induction technology. Background technique [0002] In the process of urban construction, many important combustible gas pipelines are buried under the urban road surface. If large vehicles pass by on the road surface or the earth’s crust moves, it will cause significant changes in the surrounding stress on the pipelines. Such changes will affect The pipeline forms a twisting force, which causes the pipeline to deform and even leak. At present, the monitoring of the surrounding stress of the pipeline still lacks corresponding technical means, and it is not possible to realize real-time monitoring of the stress of the pipeline, which also leaves a greater safety hazard. Summary of the invention [0003] In order to make up for the lack of this technology, the present invention pr...

[0002] In the process of urban construction, many important combustible gas pipelines are buried under the urban road surface. If there are large vehicles passing by on the road surface or the earth’s crust moves, it will cause obvious changes in the surrounding stress of the pipelines. The pipeline forms a twisting force, which causes the pipeline to deform and even leak

At present, there is still a lack of corresponding technical means for monitoring the stress around the pipeline, and it is impossible to realize real-time monitoring of the stress of the pipeline, which also leaves a large safety hazard
