Intelligent detection method for singular point characteristics of fluid conveying pipeline

Abstract

The invention discloses an intelligent detection method for singular point features of a flow conveying pipeline, and the method comprises the following steps: firstly, forming a background parameter set; secondly, installing a vibration wave parameter test micro-nano device to each node position of the to-be-tested fluid conveying pipeline, and collecting pipeline global information transmitted between any two nodes on the to-be-tested fluid conveying pipeline through the vibration wave parameter test micro-nano device; and setting a pipeline singular point fracture threshold value. According to the method, the physical characteristic that water hammer vibration waves are transmitted along a pipeline line at the moment in the running process of a fluid conveying pipeline is utilized, vibration wave transmission parameters are tested at adjacent detection nodes, and on-chip integration is achieved through a vibration wave sensor and machine learning algorithm firmware; the flow conveying pipeline material change singular point, the pipe circumference contact boundary change and the like are obtained from the vibration wave transmission parameter set based on the modes of deep learning, data fusion and the like, and pre-judgment and fixed-point maintenance are actively achieved before the flow conveying pipeline singular point fracture threshold value is achieved. And constructing a novel intelligent detection method of the fluid conveying pipeline and optimizing fluid loss control.

Description

technical field [0001] The invention relates to the technical field of flow pipeline detection, in particular to an intelligent detection method for singular point characteristics of a flow pipeline. Background technique [0002] At present, industrial pipeline transportation began in the 19th century, starting with the first crude oil pipeline built in Pennsylvania, USA in 1865. At the same time, the water supply and diversion project also involves many pipelines. It can be traced back to 2500 BC, when the Sumerians built aqueducts and tunnels in southern Mesopotamia. Pipeline transportation has gradually developed into one of the five major modes of human material transportation. The general transportation objects are fluids, mainly including water, crude oil, natural gas, etc., and a small amount of solid particles are also transported by wind. The characteristics of pipeline transportation mainly include the huge transportation volume, the transportation time is not bou...
