Method and system for monitoring vibration and deformation of pipeline

Abstract

The invention discloses a pipeline vibration deformation monitoring method and system, wherein the method includes: based on the vibration sensor arranged along the pipeline, collecting the vibration signal of the underground environment of the current pipeline in real time and writing it into a GPRS module for data encapsulation; The final data is sent to the cloud server based on the communication base station; judge whether the vibration amplitude in the packaged data is greater than the preset vibration amplitude; if it is greater, start the Brillouin scattered light collection equipment within the monitoring range of the vibration sensor and set it on the pipeline The Brillouin scattered light signal of the optical fiber is written into the GPRS module for data packaging; the packaged data is sent to the cloud server; the Brillouin scattered light signal obtained according to the packaged data is imported into the stimulated Brillouin model for analysis, and the analysis results are obtained ; and generate a monitoring and early warning command to give an early warning to the management client. In the embodiment of the present invention, the real-time monitoring of the deformation of the pipeline can be realized through the vibrator and the Brillouin scattered light collection device.

Description

technical field [0001] The invention relates to the technical field of monitoring underground pipelines, in particular to a method and system for monitoring vibration and deformation of pipelines. Background technique [0002] With the process of urbanization and the development of deep-buried pipeline technology, almost all pipelines in cities are buried deep underground. For the monitoring and management of underground pipelines, most of them now use manual inspection or information monitoring; however, using The manual inspection method requires a lot of manpower and material resources, and it cannot quickly and accurately discover or predict possible pipeline safety hazards; however, the use of information-based monitoring requires all information-based collection equipment to start monitoring in real time. It will greatly accelerate the aging of monitoring equipment and increase monitoring costs; and the information monitoring method is a network-wide monitoring method,...
