Description

Technical Field

[0001] The present invention relates to the technical field of pipeline leakage detection, and in particular to an anti-interference method and system based on audio pipeline leakage monitoring. Background Art

[0002] Underground pipelines are pipes laid underground to transport liquids, gases or loose solids. They are the lifeline of the city and ensure the daily life of urban residents. Leakage of underground pipelines will directly affect the normal operation of living areas or industrial areas. Therefore, leak detection of underground pipelines is an important task to ensure the safety and efficiency of pipeline systems such as water supply and gas supply. With the development of urbanization, underground pipeline networks have become more and more complex, so leak detection technology has become increasingly important.

[0003] The more common underground pipeline measurements include acoustic detection, gas detection, pressure detection, tracer detection and electromagnetic induction.

[0004] Acoustic detection is one of the most commonly used methods, especially for metal pipes. The leak point usually produces sound or vibration of a specific frequency, which can be heard by ground monitoring equipment (such as leak detection rods, electronic leak detection instruments), thereby determining the approximate location of the leak.

[0005] Gas detection is mainly used for gas pipelines. Specialized gas detectors can be used to detect the concentration of natural gas or other gases in the air. If the gas concentration in a certain area is abnormally high, it may indicate a leak there.

[0006] The pressure test method is generally to close the pipeline system, increase pressure at one end of the pipeline, and then observe the pressure changes inside the pipeline. If the pressure drops too quickly, it means there may be a leak.

[0007] The tracer detection method involves injecting harmless chemicals into the pipeline as tracers, and then using special instruments on the surface to track the substances to locate the leak point.

[0008] The electromagnetic induction method is mainly applicable to pipes made of non-metallic materials. It determines whether there is damage or cracks by emitting electromagnetic waves of a specific frequency and receiving the reflected information.

[0009] Among the above methods for detecting pipelines, acoustic detection is the most common. At present, the leakage monitoring of underground pipelines is mainly completed by regular manual inspections. However, due to interference from external environmental noise during the detection process, the detection efficiency is low and the leakage point cannot be quickly determined.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0046] See also Figure 1 To achieve the above purpose, in a first embodiment of the present invention, an anti-interference method based on audio pipeline leakage monitoring includes:

[0047] Step S10, obtaining a leakage sound wave library and a noise sound wave library;

[0048] Step S20, acquiring each real-time sound wave data, denoising each real-time sound wave data according to each noise sound wave library, and determining each denoised sound wave data;

[0051] Step S50, performing field detection on each predicted leaking pipe section by means of a calibration device to determine the real-time leakage point.

[0052] The noise in the real-time sound wave data is removed through the noise sound wave library, and the predicted leaking pipeline where the leak may occur is determined through comparison. Finally, the predicted leaking pipeline is calibrated and tested through the calibration device to determine the exact location of the real-time leakage point, thereby minimizing the interference of external environmental noise. The accuracy of the test results is ensured through multiple tests, which effectively improves the detection efficiency.

[0053] Specifically, after step S40, the following steps are included:

[0054] Step S41, determining whether the number of preset leaking pipelines is greater than one;

[0055] Step S42, when the number of predicted leaking pipelines is equal to one, executing step S50;

[0056] Step S43, when the number of predicted leaking pipes is greater than one, obtaining the position data of the calibration device, and determining the predicted leaking pipe section closest to the position data as the starting point according to the position data and each predicted leaking pipe section;

[0057] Step S44, determining the detection order according to the starting point and each predicted leaking pipeline;

[0058] Step S50 includes:

[0059] Step S51, the calibration device performs field detection on each predicted leaking pipe section in turn according to the detection sequence to determine the real-time leakage point.

[0060] According to the number and distance of predicted leaking pipelines, the detection sequence is set to ensure that the detection tasks are completed in an orderly and rapid manner.

[0061] In the second embodiment of the present invention, based on the first embodiment, step S20 includes:

[0062] Step S21, acquiring each real-time sound wave data, denoising each real-time sound wave data according to the noise sound wave library, and determining each initial sound wave data;

[0063] Step S22, determining whether there are invalid sound waves in each initial sound wave data;

[0064] Step S23, when there are no invalid sound waves in each of the initial sound wave data, determining each of the initial sound wave data as each of the noise-removed sound wave data;

[0065] Step S24, when any of the initial sound wave data contains invalid sound waves, determining the type of the invalid sound waves;

[0066] Step S25, when the type of the invalid sound wave is a noise sound wave, the invalid sound wave of the type of the noise sound wave is recorded into the noise sound wave library, and the steps of obtaining each real-time sound wave data and determining each initial sound wave data according to each real-time sound wave data and the noise sound wave library are executed;

[0067] Step S26, when the type of the invalid sound wave is a leakage sound wave, the invalid sound wave of the leakage sound wave type is recorded into the leakage sound wave library, and the steps of obtaining each real-time sound wave data and determining each initial sound wave data according to each real-time sound wave data and the noise sound wave library are executed.

[0068] According to the invalid sound waves in the real-time sound wave data, the noise sound wave library and the leakage sound wave library are used to minimize external interference.

[0069] In the third embodiment of the present invention, based on the second embodiment, step S40 includes:

[0070] Step S45, determining the detection position point corresponding to each piece of leaked real-time sound wave data according to each piece of leaked real-time sound wave data;

[0071] Step S46, obtaining the laying data of the underground pipeline, and determining at least two adjacent detection position points to form a detection group according to the laying data and each detection position point;

[0072] Step S47, determining the predicted leaking pipe section according to each detection group.

[0073] At least two audio sensors are set on a single pipeline for real-time acoustic wave detection, so the real-time acoustic wave data of the leak point is detected by at least two adjacent audio sensors (i.e., detection position points). Therefore, by detecting the pipelines where multiple adjacent audio sensors are located, the detection accuracy is effectively improved.

[0074] Specifically, after step S46, the following steps are included:

[0075] Step S47, judging whether there is a separate detection position point according to the laying data and each detection position point;

[0076] Step S48, when there is no single detection position point among the detection position points, execute step S47;

[0077] Step S49, if there is a separate detection position point among the detection position points, determine the interval distance between each separate detection position point and each detection group;

[0078] Step S410: When the interval distances between each individual detection position point and each detection group are greater than or equal to a preset distance, execute step S47.

[0079] Step S411, when the interval distance between any single detection position point and any detection group is less than a preset distance, the single detection position point is confirmed as a single inspection point;

[0080] Step S412: Determine the predicted leaking pipe section according to each individual inspection point and each detection group.

[0081] If the distance between individual pipelines is too close, or the sound wave intensity at the leakage location is high, it will interfere with the detection of the audio sensor. In order to ensure the accuracy of the detection, it is also necessary to judge based on the predicted distance of the interval.
