Abstract

The invention provides an optical fiber deformation monitoring system for oil and gas pipelines. A data control module is used for controlling an optical pulse transmitting module to send pulse signals to a coupler, accumulating received digital signals and then sending the digital signals to a data processing module. The coupler is used for coupling phase change signals generated by an optical fiber due to soil deformation around the oil and gas pipelines and the pulse signals of preset frequency and then sending the coupled signals to an optical signal receiving module. The optical signal receiving module is used for enabling the coupled signals to be sent to an analog-digital conversion module to be converted into digital signals and sent to the data control module. The data processing module is used for sending control demands for controlling cumulative frequency to the data control module and enabling the received accumulated digital signals to be compared with stored data so as to determine whether the oil and gas pipelines are leaked. The optical fiber deformation monitoring system has a long monitoring distance, is low in cost and simple in structure, can be used for detecting small deformation of the pipelines, and is high in accuracy and reliability.

Description

technical field [0001] The invention relates to an oil and gas pipeline optical fiber deformation monitoring system, which belongs to the technical field of oil and gas pipeline monitoring. Background technique [0002] With the progress of society and the continuous development of the economy, the consumption of energy by the whole society is also increasing. The problem of energy supply has become the focus of attention in the world. The problem of energy supply is also related to the stability of the whole society and economic development. Among the existing energy sources, oil and gas account for the majority of energy consumption. [0003] Oil and gas are mainly transported through pipelines. Oil and gas pipelines are characterized by large transport volume, thick pipeline diameter, long transport distance, continuous and stable transport process, and relatively low freight costs. At the same time, the problem of safe transportation of oil and gas pipelines has also be...
