Oil pipeline security monitoring system based on fiber Bragg grating sensor

More Information
  • This paper proposes a security monitoring system based on fiber Bragg grating sensors for pipelines in landslide area and presents the method on how to obtain maximum stress if stress values of three points on the pipeline are available. Based upon this method, this system applies FBG sensors developed by ourselves to monitor stress of the pipeline. With the good immunity to electromagnetic interference, corrosion resistance and good stability, such FBG sensors can realize temperature compensation, eliminate impact of temperature on measuring results and measure ambient temperature. This system implements automatic measurement and data storage by optical switch and optical sensing interrogator and transfers data by GPRS. According to field results, this system is capable of realizing real time monitoring and stable in performance.
