Abstract

The invention discloses an arrangement structure and an arrangement method of an optical fiber sensor on a gas pipeline. The arrangement structure comprises a plurality of wiring supports and opticalfiber sensors; the wiring supports are arranged at preset positions of the gas pipeline; and the optical fiber sensors are installed on the wiring supports in a one-to-one correspondence mode, and theoptical fiber sensors are laid on the gas pipeline in the radial direction or the axial direction so that vibration information collection points of multiple dimensions can be formed on the gas pipeline. The crosstalk caused by irrelevant factors such as temperature is avoided, anti-interference capability of a system is improved, and the safety monitoring accuracy of the gas pipeline is improved. And meanwhile, more data support is provided for system safety early warning, and the false alarm rate of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of gas pipeline safety protection, in particular to an arrangement structure and method of an optical fiber sensor on a gas pipeline. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] As an important infrastructure for industrial production and urban civilian use, gas pipelines play an important role in urban development and people's daily life. As the carrying equipment for flammable and explosive dangerous gases such as natural gas, liquefied petroleum gas, and coal gas, once a leak occurs, it will cause huge social dangers, and it will also cause huge economic losses to the gas company. Therefore, the safe operation of urban gas pipelines is of great significance to social economy, production and life, and people's well-being. [0004] There are many reasons for gas pipeline leakage, such as pipeli...
