Municipal pipeline vulnerability prediction and early warning method and system

Abstract

The invention discloses a municipal pipeline vulnerability prediction and early warning method which comprises the steps of arranging a vibration sensor on a municipal pipeline, constructing a vibration data collection network, obtaining vibration data at a time interval T0, filtering the vibration data, forming a vibration data set, performing offset correction on the vibration data set, and judging the position of the leakage point according to the vibration data set, and giving an alarm according to the position of the leakage point. The defects of traditional municipal pipeline vulnerability early warning based on pressure and flow are avoided, for example, the defects that an existing pipeline needs to be subjected to invasive transformation, the false alarm rate is large and the response is slow are overcome, and accurate vulnerability prediction of the municipal pipeline is achieved.

Description

technical field

[0001] The invention relates to the technical field of municipal infrastructure pipeline monitoring, in particular to a municipal pipeline loophole prediction and early warning method and system. Background technique

[0002] In the background discussion below, reference is made to certain structures and / or methods. However, the following references should not be construed as an admission that these structures and / or methods constitute prior art. Applicant expressly reserves the right to demonstrate that such structures and / or methods do not constitute prior art.

[0003] With the development of municipal infrastructure, all kinds of municipal pipelines are intricate and complicated. The pipeline leakage caused by pipeline occupation, corrosion and aging threatens the safe and normal operation of the municipal pipeline system. It can effectively monitor the municipal pipeline in real time and locate the leakage location. Disasters can be avoided. However, ...
