Title:
PIPELINE STRUCTURE FAULT DIAGNOSIS APPARATUS, AND DIAGNOSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2023/040011
Kind Code:
A1
Abstract:
A pipeline (10) structure fault diagnosis apparatus, and a diagnosis method, which belong to the technical field of natural gas pipeline (10) safety, and aim to fill the gap in the prior art of the lack of apparatuses for implementing pipeline (10) structure multi-fault integrated diagnosis for natural gas pipelines (10). A signal generation apparatus is used for generating an acoustic wave signal when a pipeline (10) is struck; a signal collection apparatus (40) is used for collecting the acoustic wave signal; and a signal storage apparatus (50) is used for storing the acoustic wave signal for a signal processing and analysis apparatus (70) to perform analysis and determine a fault type, a fault degree and a fault position. After the signal generation apparatus generates the acoustic wave signal, the acoustic wave signal is collected by means of the signal collection apparatus (40), and is stored in the signal storage apparatus (50); the signal processing and analysis apparatus (70) extracts the acoustic wave signal from the signal storage apparatus (50), and performs processing and analysis, so as to determine the fault type, fault degree and fault position of the pipeline (10) structure, which is beneficial for performing fault inspection on the pipeline (10) in a timely manner, thereby guaranteeing safe operation of the pipeline (10).
