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
The present invention relates to optics, art of electronics, particularly relate to a kind of urban pavement underground pipelines construction sniffer based on electromagnetic induction technology.
Background technology
In Process of Urban Development, there are a lot of important inflammable gas pipelines to be imbedded under the road surface in city, if have oversize vehicle process or the earth's crust to move on road surface, all by the edge stress generation significant change that causes pipeline to bear, such variation meeting forms distortion power to pipeline, thereby cause pipeline distortion, even leak.At present, the monitoring of pipeline edge stress is also lacked to relevant art means, also cannot realize monitoring in real time to the stressing conditions of pipeline, also left larger potential safety hazard.
Summary of the invention
In order to make up the disappearance of this technology, the invention provides and a kind ofly there is Real-Time Monitoring pipeline stressing conditions the underground pipeline safety monitoring assembly based on stress induction technology that can give the alarm in time based on bragg fiber sensor, data processor and alarm installation composition in the time that pipeline stress approaches dangerous values.
The technical solution adopted in the present invention is: comprise bragg fiber sensing module, data processing module and alarm module.The data input pin of the data output end connection data processing module of bragg fiber sensing module, the data output end of data processing module connects the data input pin of alarm module.
Further, bragg fiber sensing module, by the sensor network of organizing Bragg optical-fiber grating sensor more and forming, is dispersed throughout whole underground piping system, by long-range stress induction, to monitor the stressing conditions of each pipeline, thereby stressing conditions is sent to data processor in time.
Further, data processing module is set corresponding threshold value according to the residing varying environment of pipeline, and the stress situation that Fibre Optical Sensor is transported is analyzed, if stress exceedes or approaches threshold value, send signal to alarm module, to report to the police in time, the generation of the incidents that averts a calamity.
The present invention has advantages of:
1. remote monitoring stress situation; 2. broad covered area, realizes overall monitor 3. monitor procedure full-automations to pipeline, and threshold value can be set flexibly, rapid reaction.
Accompanying drawing explanation
Fig. 1 is block diagram of the present invention; Fig. 2 is configuration schematic diagram of the present invention.
Embodiment
As shown in Figure 1, bragg fiber sensing module forms by organizing Bragg optical-fiber grating sensor more, is dispersed throughout whole underground pipeline system, by long-range stress induction, to monitor the stressing conditions of each pipeline, thereby stressing conditions is sent to data processor in time.Data processing module is set corresponding threshold value according to the residing varying environment of pipeline, and the stress situation that Fibre Optical Sensor is transported is analyzed, if stress exceedes or approaches threshold value, sends signal to alarm module, to report to the police in time.
Described bragg fiber sensing module refers to a kind of at novel sensor, grating is periodically distributing in the inner space phase forming of fibre core of this sensor, to play the effect of catoptron and wave filter, reflect thereby select the wavelength that meets Bragg condition, to improve propagation efficiency.Mainly be arranged near pipeline, to detect the stressing conditions of each pipeline.
Described data processing module refers to a kind of microprocessor with data analysis, arrangement, before application prerequisite, write stress threshold calculation procedure, according to the suffered stress situation of the each pipeline receiving, to judge that the suffered stress of this pipeline is whether in safe range, if exceed safety value, send information to alarm module in time, report to the police.
Described alarm module and data processing module join, and in the time receiving information, send voice alarm to City Buried Pipeline control center.
As shown in Figure 2, bragg fiber inductor 2 is distributed near pipeline 1, the suffered stress situation of pipeline is monitored, after image data, be delivered to fast data processor 3, data processor is according to the stress situation sending, compare according to environmental selection respective threshold under it, judge whether its stress exceeds safe range, if stress reaches threshold value, send prompting to alarm device 4, alarm device 4 gives the alarm in time, shows to have pipeline stress to depart from normal value, should keep in repair early.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
