Pipeline safety early warning system based on distributed optical fiber sensing

Abstract

The invention discloses a pipeline safety early warning system based on distributed optical fiber sensing. The system comprises a management system, a monitoring host, a sensing optical cable and a mobile terminal. The monitoring host is respectively connected with the sensing optical cable and the management system and is used for collecting, analyzing and processing variation and converting thevariation into an electric signal. The management system is further connected with the mobile terminal and is used for receiving the electric signal and sending an early warning signal to the mobile terminal when judging that a safety condition occurs according to the electric signal. According to the invention, a pipeline line safety early warning system is realized by designing a distributed optical fiber sensing technology; early warning can be given out before substantive damage to pipeline facilities is not caused; real-time monitoring can be realized; problems that the traditional inspection efficiency is low and the mode is discontinuous are solved; the management system can give an alarm and accurately locate a third-party event and the system can be notified to rush to the scene for key monitoring or emergency measure taking in a short message mode, a mobile phone APP mode, an intelligent terminal mode and the like. The pipeline safety early warning system has the high marketapplication value.

Description

technical field [0001] The present invention relates, in particular, to a pipeline line safety early warning system based on distributed optical fiber sensing. Background technique [0002] The safety of optical cables and the safety of oil and gas pipelines are important facilities related to the production economy. Any leakage accident will bring huge economic losses, environmental pollution and even threaten personal and property safety. Third-party incidents that threaten the safety of pipelines such as trenching, house building, road repair, natural disasters, oil and gas smuggling, and vandalism along the pipeline occur from time to time. For example, leakage of oil and gas pipelines may cause serious safety accidents such as pipeline explosion, deflagration, and oil pollution; directional drilling near the pipeline may also cause serious damage to oil and gas pipelines or optical cables in operation; Oil and gas pipelines for high-pressure transmission may spray crud...

Problems solved by technology

[0003] Traditional pipeline protection methods are usually based on pipeline operating parameters, such as flow, pressure and other operating parameters, which belong to post-event detection, while the protection measures before the pipeline is damaged mainly rely on manual inspection and public reporting, and manual inspection cannot be realized7 *24-hour continuous inspection, and there are blind spots, and the deviation of leakage alarm is large
