On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0040] Figure 1 It is a flow chart of a method for detecting leakage of hydrogen-blended natural gas based on holographic interferometry proposed in one embodiment of the present disclosure.

[0041] It should be noted that the executor of the hydrogen-doped natural gas leakage detection method based on holographic interferometry in this embodiment is a hydrogen-doped natural gas leakage detection device based on holographic interferometry, which can be implemented by software and / or hardware. The device can be configured in a computer device, and the computer device can include but is not limited to a terminal, a server, etc. For example, the terminal can be a mobile phone, a handheld computer, etc.

[0042] like Figure 1 As shown, the hydrogen-doped natural gas leakage detection method based on holographic interference includes:

[0043] S101: Acquire a first initial light beam and a second initial light beam.

[0044] The initial light beam refers to a light beam that has not passed through the reference area or the detection area, and may be, for example, a laser, which is not limited thereto. The first initial light beam and the second initial light beam refer to two different initial light beams.

[0045] In the embodiment of the present disclosure, when the first initial light beam and the second initial light beam are acquired, reliable initial light beams can be provided for the subsequent acquisition of the first target light beam and the second target light beam.

[0046] S102: Controlling the first initial light beam to pass through a reference area to obtain a first target light beam, wherein there is no hydrogen-doped natural gas in the reference area.

[0047] The reference area may refer to any area where hydrogen-doped natural gas does not exist. For example, the reference area may be an area in a normal air environment.

[0048] In the disclosed embodiment, when the first initial light beam is controlled to pass through the reference area to obtain the first target light beam, the obtained first target light beam can be used as a reference light beam to provide reliable light beam support for the subsequent formation of detection interference fringes.

[0049] S103: Control the second initial light beam to pass through the detection area to obtain a second target light beam.

[0050] The detection area may refer to an area where hydrogen-blended natural gas leakage detection is to be performed. The detection area may refer to an area where hydrogen-blended natural gas leakage may occur, or may refer to an area where gas samples to be detected are pre-configured, without limitation.

[0051] In the disclosed embodiment, when the second initial light beam is controlled to pass through the detection area to obtain the second target light beam, the obtained second target light beam can accurately indicate the situation in which the air in the detection area is affected by the leakage of hydrogen-blended natural gas.

[0052] S104: Based on the first target light beam and the second target light beam, detection interference fringes are formed.

[0053] The detection interference fringes may refer to interference fringes formed based on the first target light beam and the second target light beam, and may be used to indicate the degree to which the detection area is affected by the leakage of hydrogen-blended natural gas.

[0054] In the embodiment of the present disclosure, when detection interference fringes are formed based on the first target light beam and the second target light beam, the obtained detection interference fringes can accurately indicate the difference information between the reference area and the detection area, thereby providing reliable reference information for determining the hydrogen-blended natural gas leakage detection result in the detection area.

[0055] S105: Determine the hydrogen-blended natural gas leakage detection result in the detection area according to the detected interference fringes.

[0056] For example, in the embodiments of the present disclosure, when determining the leakage detection result of the hydrogen-blended natural gas in the detection area based on the detected interference fringes, the detected interference fringes may be input into a pre-trained machine learning model to obtain the corresponding leakage detection result of the hydrogen-blended natural gas in the detection area. Alternatively, any other possible method may be used to determine the leakage detection result of the hydrogen-blended natural gas in the detection area based on the detected interference fringes, and there is no limitation to this.

[0057] In this embodiment, by acquiring a first initial light beam and a second initial light beam, the first initial light beam is controlled to pass through a reference area to obtain a first target light beam, wherein hydrogen-added natural gas does not exist in the reference area, and the second initial light beam is controlled to pass through a detection area to obtain a second target light beam, and detection interference fringes are formed based on the first target light beam and the second target light beam, and a detection result of a hydrogen-added natural gas leakage in the detection area is determined according to the detection interference fringes, thereby, based on the holographic interference technology, detection interference fringes that accurately indicate gas characteristic information in the detection area can be obtained, thereby quickly and accurately obtaining a hydrogen-added natural gas leakage detection result based on the detection interference fringes, and effectively improving the detection effect of hydrogen-added natural gas leakage.

[0058] Figure 2 It is a flow chart of a hydrogen-blended natural gas leakage detection method based on holographic interferometry proposed in another embodiment of the present disclosure.

[0059] like Figure 2 As shown, the hydrogen-doped natural gas leakage detection method based on holographic interference includes:

[0060] S201: Acquire an initial laser beam.

[0061] The initial laser beam may refer to an unprocessed beam provided by a laser.

[0062] It can be understood that in the embodiment of the present disclosure, when the initial laser beam is obtained as the initial beam, at least the following advantages are included:

[0063] (1) High monochromaticity: Laser has an extremely narrow spectral width and can produce highly monochromatic light.

[0064] (2) High directivity: Lasers have extremely high directivity and can focus energy in a very small area, making the optical signal more stable and accurate.

[0065] (3) Coherence: Lasers have extremely high coherence and can produce optical phenomena such as interference and diffraction.

[0066] (4) High brightness: Lasers have high-intensity beams and can provide sufficient light intensity for high-sensitivity optical measurements.

[0067] (5) Easy to control: The output of the laser can be controlled by adjusting the parameters of the laser, such as light intensity, frequency, polarization, etc. This makes the laser more convenient to use in experiments.

[0068] S202: Perform beam expansion and collimation processing on the initial laser beam to obtain a target laser beam.

[0069] In the disclosed embodiment, when the initial laser beam is expanded, the spot area of ​​the beam can be increased, making the light power distribution more uniform. When the initial laser beam is collimated, the beam can be made more parallel and more directional.

[0070] S203: performing beam separation processing on the target laser beam to obtain a first initial beam and a second initial beam.

[0071] For example, in the embodiment of the present disclosure, the target laser beam may be subjected to beam separation processing based on a beam splitter to obtain a first initial beam and a second initial beam.

[0072] Optionally, in some embodiments, the first initial light beam and the second initial light beam are perpendicular to each other, thereby effectively avoiding mutual interference between light beams in different directions, thereby greatly improving the reliability of the detection process.

[0073] That is to say, in the embodiments of the present disclosure, an initial laser beam can be obtained, and the initial laser beam can be expanded and collimated to obtain a target laser beam, and the target laser beam can be separated to obtain a first initial beam and a second initial beam. Thus, the consistency of the optical properties of the first initial beam and the second initial beam can be ensured, thereby effectively improving the reliability and practicality of the first initial beam and the second initial beam during the detection process.

[0074] S204: Controlling the first initial light beam to pass through a reference area to obtain a first target light beam, wherein no hydrogen-doped natural gas exists in the reference area.

[0075] S205: Control the second initial light beam to pass through the detection area to obtain a second target light beam.

[0076] S206: Based on the first target light beam and the second target light beam, detection interference fringes are formed.

[0077] The description of S204-S206 can be specifically referred to the above embodiment, which will not be repeated here.

[0078] S207: Acquire reference interference fringes, wherein the hydrogen-blended natural gas leakage detection result corresponding to the reference interference fringes is that there is no hydrogen-blended natural gas leakage.

[0079] For example, in the embodiment of the present disclosure, when obtaining reference interference fringes, a communication link between the execution entity of the embodiment of the present disclosure and a big data server may be established in advance, and then the reference interference fringes may be obtained from the big data server. Alternatively, any other possible method may be used to obtain the reference interference fringes, without limitation.

[0080] Optionally, in some embodiments, when obtaining reference interference fringes, the second initial light beam can be controlled to pass through a reference area to obtain a third target light beam, and reference interference fringes are formed based on the first target light beam and the third target light beam. This can effectively improve the adaptability of the obtained reference interference fringes in personalized application scenarios.

[0081] S208: Determine difference information between the detected interference fringes and the reference interference fringes.

[0082] The difference information can be used to describe the difference between the detected interference fringes and the reference interference fringes.

[0083] That is, in the embodiment of the present disclosure, after obtaining the detection interference fringes and the reference interference fringes, the difference information between the detection interference fringes and the reference interference fringes can be determined, thereby providing a reliable basis for generating hydrogen-blended natural gas leakage detection results.

[0084] S209: Generate hydrogen-blended natural gas leakage detection results based on the difference information.

[0085] For example, when generating a hydrogen-blended natural gas leakage detection result based on difference information in the embodiment of the present disclosure, a corresponding difference value may be determined based on the difference information, and then whether a hydrogen-blended natural gas leakage occurs may be determined based on the difference value, and the leakage speed of the hydrogen-blended natural gas may also be determined.

[0086] That is to say, in the embodiment of the present disclosure, after obtaining the detection interference fringes, reference interference fringes can be obtained, wherein the hydrogen-added natural gas leakage detection result corresponding to the reference interference fringes is that there is no hydrogen-added natural gas leakage, and the difference information between the detection interference fringes and the reference interference fringes is determined. Based on the difference information, the hydrogen-added natural gas leakage detection result is generated, thereby effectively improving the detection performance based on the difference information between the detection interference fringes and the reference interference fringes.

[0087] In this embodiment, by obtaining an initial laser beam, the initial laser beam is expanded and collimated to obtain a target laser beam, and the target laser beam is separated to obtain a first initial beam and a second initial beam, thereby ensuring the consistency of the optical properties of the first initial beam and the second initial beam, thereby effectively improving the reliability and practicality of the first initial beam and the second initial beam in the detection process. The first initial beam and the second initial beam are perpendicular to each other, thereby effectively avoiding mutual interference between light beams in different directions, thereby greatly improving the reliability of the detection process. By obtaining reference interference fringes, wherein the hydrogen-doped natural gas leakage detection result corresponding to the reference interference fringes is no hydrogen-doped natural gas leakage, determining the difference information between the detection interference fringes and the reference interference fringes, and generating the hydrogen-doped natural gas leakage detection result based on the difference information, thereby effectively improving the difference information between the detection interference fringes and the reference interference fringes. By controlling the second initial beam to pass through the reference area to obtain a third target beam, reference interference fringes are formed based on the first target beam and the third target beam, thereby effectively improving the adaptability of the obtained reference interference fringes in personalized application scenarios.

[0088] Figure 3 It is a structural schematic diagram of a hydrogen-blended natural gas leakage detection device based on holographic interferometry proposed in an embodiment of the present disclosure.

[0090] An acquisition module 301 is used to acquire a first initial light beam and a second initial light beam;

[0094] The determination module 305 is used to determine the hydrogen-blended natural gas leakage detection result in the detection area according to the detected interference fringes.

[0095] It should be noted that the aforementioned explanation of the hydrogen-blended natural gas leakage detection method based on holographic interferometry is also applicable to the hydrogen-blended natural gas leakage detection device based on holographic interferometry of this embodiment, and will not be repeated here.

[0096] In this embodiment, by acquiring a first initial light beam and a second initial light beam, the first initial light beam is controlled to pass through a reference area to obtain a first target light beam, wherein hydrogen-added natural gas does not exist in the reference area, and the second initial light beam is controlled to pass through a detection area to obtain a second target light beam, and detection interference fringes are formed based on the first target light beam and the second target light beam, and a detection result of a hydrogen-added natural gas leakage in the detection area is determined according to the detection interference fringes, thereby, based on the holographic interference technology, detection interference fringes that accurately indicate gas characteristic information in the detection area can be obtained, thereby quickly and accurately obtaining a hydrogen-added natural gas leakage detection result based on the detection interference fringes, and effectively improving the detection effect of hydrogen-added natural gas leakage.
