Embodiment Construction

[0045] The principles and features of the present invention will be described below with reference to the accompanying drawings. The embodiments are only used to explain the present invention, but not to limit the scope of the present invention.

[0046] like figure 1 As shown, a method for identifying natural gas pipe body leakage based on voiceprint identification provided by an embodiment of the present invention includes:

[0047] S1, input the collected voiceprint information of the natural gas pipe body;

[0048] S2, performing real-time detection on the voiceprint information of the natural gas pipe body through the optimized DFCNN model;

[0049] S3, when the detection result is that the identification matches the voiceprint marked with the category of leaked natural gas, and the matching degree is higher than the preset value, it is determined that there is natural gas leakage, the current time is recorded, and an alarm is sent. The preset value may be that the matc...

Abstract

The invention discloses a natural gas pipe body leakage recognition method and system based on voiceprint recognition, and relates to the field of natural gas leakage recognition. The method comprises the steps that collected voiceprint information of a natural gas pipe body is input, real-time detection is conducted on the voiceprint information of the natural gas pipe body through an optimized DFCNN model, when the detection result is that voiceprint marked with leaked natural gas categories is recognized and matched, and the matching degree is higher than a preset value, it is judged that natural gas leakage exists, the current moment is recorded, and the natural gas leakage is detected. The intelligent recognition of the voiceprint of the natural gas leakage of the pipe body is realized, the artificial intelligence can be helped to recognize the voiceprint condition of the natural gas leakage of the pipe body, the safety risk of pipeline breakage is reduced, and the pipeline safety management and control capability is improved.

Description

technical field [0001] The invention relates to the field of natural gas leakage identification, in particular to a method and system for natural gas leakage identification based on voiceprint identification. Background technique [0002] With the economic development, the construction and construction carried out for the needs of the economic development of various regions will increase, which will inevitably interact with the increasing pipeline network. In recent years, natural gas pipeline ruptures and gas leakage accidents have occurred frequently due to pipeline quality or environmental changes. It brings a lot of pressure to the safe management and operation of pipelines. [0003] In order to strengthen pipeline quality management, in recent years, smart balls have been tested. There are sound collectors in the balls. After collecting the sound of the natural gas leakage point in the pipeline, the engineer analyzes it. Alarm, find the relevant leak point and repair ...
