Underground pipeline identification and monitoring system and use method

Abstract

The invention discloses an underground pipeline identification and monitoring system and a use method. The system comprises a pipeline instrument and a geological radar, a strain sensing optical fiber, a temperature compensation optical fiber, an optical fiber data acquisition and transmission system, an optical fiber data processing and analysis system, a monitoring result display system and a pipeline CCTV (Closed Circuit Television Inspection) detection system. A pipeline is identified through the pipeline instrument and the geological radar; real-time optical fiber acquisition and transmission are carried out through distributed sensing optical fibers outside the pipeline and the optical fiber data acquisition and transmission system, and stress, temperature and deformation of the pipeline are obtained through the optical fiber data processing system; and the pipeline CCTV detection system is used for carrying out pipeline rust layer, scaling, corrosion, perforating, crack detection and camera shooting. The underground pipeline identification and monitoring system is rapid and accurate in positioning, long in monitoring distance, comprehensive in collected data and high in sensitivity and accuracy, and rapid and accurate identification and monitoring of the underground pipeline are achieved.

Description

technical field [0001] The invention relates to the technical field of underground pipeline network monitoring, in particular to an identification and monitoring system for underground pipelines and a use method. Background technique [0002] Urban underground pipelines are an important part of urban infrastructure. Underground pipelines are the "vessels" and "nerves" of cities, as well as the lifelines of cities. With the rapid development of urban construction, my country has increased the development and utilization of underground space in recent years, and more and more underground pipelines have been laid in cities. Due to the incompleteness of archives, the situation of the underground pipeline is unclear. In addition, the concealment of the underground pipeline makes it impossible to determine the actual location and burial depth of the pipeline. During the construction process, the damage to the underground pipeline occurs from time to time. Retrofits bring hidden dan...

Problems solved by technology

With the rapid development of urban construction, my country has increased the development and utilization of underground space in recent years, and more and more underground pipelines have been laid in cities. Due to the incompleteness of archives, the situation of the underground pipeline is unclear. In addition, the concealment of the underground pipeline makes it impossible to determine the actual location and burial depth of the pipeline. During the construction process, the damage to the underground pipeline occurs from time to time. Retrofit brings danger

If the pipeline is not monitored, repaired and cleaned up in time, accidents may occur and unnecessary losses will be caused

There has been a long history of research and application of pipeline identification and monitoring methods, but due to the complexity of pipeline identification and monitoring due to different materials, pipeline transport media, and environments, there is currently no general method that can fully meet the requirements Various pipeline identification and monitoring requirements
