Gas transmission pipeline leakage detection system based on acoustic method

Abstract

The invention discloses a gas transmission pipeline leakage detection system based on an acoustic method. The gas transmission pipeline leakage detection system comprises a user terminal, a cloud server and a plurality of detection sections, wherein the detection sections are arranged along a gas transmission pipeline; two low-frequency acoustic wave sensors, two temperature sensors, two density sensors, two pressure sensors and two digital network transmission instruments are arranged in each detection section. The gas transmission pipeline leakage detection system is high in real-time performance, high in sensitivity, high in adaptability, short in response time and high in positioning accuracy, and is capable of achieving all-day, real-time and different-area detection, positioning leakage positions and determining diameter size and shape of leakage holes.

Description

technical field [0001] The invention relates to a gas transmission pipeline leakage detection system, in particular to a gas transmission pipeline leakage detection system and detection method based on an acoustic wave method. Background technique [0002] Pipeline transportation has many advantages such as low cost, large transportation volume, stable transportation, high degree of automation, and continuous transportation in harsh environments. It is especially suitable for long-distance transportation of flammable and explosive fluids such as oil and gas. [0003] In recent years, the demand for energy in countries around the world has greatly increased, the construction of gas pipelines has entered a stage of rapid development, and the level of automation has increased rapidly. Among them, the total mileage of gas pipeline construction in my country has exceeded 80,000 kilometers. Pipeline leakage accidents often occur due to changes in environmental conditions (such as l...

Problems solved by technology

[0007] (3) The effect is better for liquid pipelines with properties close to incompressible fluids, and the leak detection and positioning effects for gas pipelines are relatively poor, or even basically unfeasible

[0008] Moreover, the existing gas pipeline leakage detection system generally adopts the mode of fixed detection station, which is inconvenient to use

It takes a long time from the detection of the leak to the taking of measures, and the best time to deal with the leak cannot be effectively grasped
