When the fault point is located in a densely built-up area, the ground location of the second fiber optic fault point is obtained by combining a GIS map with the cable length of the fiber optic fault point, resulting in a more accurate ground location. Since fiber optic maintenance is difficult in densely built-up areas, even small positional deviations can significantly increase the difficulty of fiber optic maintenance. Therefore, accurately locating the corresponding ground location of the fault point by combining a GIS map with the cable length of the fiber optic fault point can effectively improve the convenience and efficiency of cable maintenance. When the fault point is located in a sparsely built-up area, the maintenance environment is relatively relaxed, and fiber optic maintenance is less difficult. The cable length of the fiber optic fault point is input into a pre-trained historical fault data model to obtain the ground location of the third fiber optic fault point. This improves the location efficiency while ensuring that the positioning accuracy of the fiber optic fault location meets maintenance requirements. Attached Figure Description

[0054] Figure 3 is a schematic diagram of the structure of the electronic device according to an embodiment of the present invention. Embodiments of the present invention

[0055] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] To address the problems existing in the aforementioned related technologies, this embodiment provides a fiber optic fault location method, device, electronic device, and storage medium.

[0057] As shown in Figure 1, an embodiment of the present invention provides a fiber optic fault location method, comprising:

[0058] Step 110: Collect raw fiber attenuation information using a fiber optic interferometer.

[0059] Specifically, a laser is input at the input end of the optical fiber, the reflected light signal is received by an optical fiber interferometer, the recovered light signal is converted into an electrical signal by a photoelectric converter, and the obtained electrical signal is converted into an analog-to-digital signal by an analog-to-digital converter to obtain the attenuation information of the laser at different positions in the optical fiber.

[0060] Step 120: Obtain the cable length at the fiber optic fault point based on the original fiber optic attenuation information, wherein the cable length at the fiber optic fault point is used to represent the cable length from the fiber optic input end to the fiber optic fault point.

[0061] Specifically, a suitable wavelet basis function is selected to perform wavelet decomposition on the original fiber attenuation information to obtain the decomposed original fiber attenuation information, wherein the wavelet basis function is used to represent signal analysis and processing in wavelet transform; a suitable threshold is selected to quantize the decomposed original fiber attenuation information to obtain the quantized original fiber attenuation information; the quantized original fiber attenuation information is denoised to obtain the denoised original fiber attenuation information; singularity analysis is performed on the denoised original fiber attenuation information by performing wavelet decomposition to obtain singular points; the cable length of the fiber fault point is obtained based on the singular points, wherein the singular points are used to indicate the location of the fault.

[0062] Step 130: Obtain the ground location of the first optical fiber fault point based on the standard reference point cable length, the standard reference point ground location, and the optical fiber fault point cable length.

[0063] Specifically, by applying external force to a pre-set standard reference point to bend the cable, the optical fiber inside the cable bends, thereby changing the optical fiber attenuation at the standard reference point. The cable length from the optical fiber input end to the standard reference point is then measured to obtain the standard reference point cable length. Using the standard reference point cable length and the ground position of the standard reference point as references, the cable length of the optical fiber fault point is converted into the ground position of the first optical fiber fault point.

[0064] Step 140: Determine the fault point zone based on the ground location of the first fiber optic fault point, wherein the fault point zone includes densely built areas and sparsely built areas.

[0065] Specifically, the area where the optical fiber fault occurred is located by the ground location of the first optical fiber fault point. The entire area is divided into a densely built area and a sparsely built area. The densely built area is a relatively densely built area, which is more difficult to repair the direct-buried optical fiber fault point.

[0066] Step 151: When the fault point is zoned as the densely built area, the ground location of the second optical fiber fault point is obtained according to the GIS map and the cable length of the optical fiber fault point, wherein the GIS map is used to represent the distribution of optical fiber lines.

[0067] Specifically, by acquiring fiber optic line drawings, generating a GIS map based on the fiber optic line drawings, and drawing a fiber optic line diagram.

[0068] Step 152: When the fault point is zoned as the sparse building area, the cable length of the fiber optic fault point is input into the pre-trained historical fault data model to obtain the ground location of the third fiber optic fault point.

[0069] Specifically, the pre-trained historical fault data model can be trained by a neural network model, which is capable of learning and recognizing complex patterns and relationships and is suitable for various tasks such as classification, regression and generation.

[0070] In this embodiment, the cable length of the fiber optic fault point is obtained based on the fiber optic attenuation information. The ground location of the first fiber optic fault point is determined first using the cable length and ground location of a standard reference point. The ground location of the first fiber optic fault point is then used to determine whether the area where the fault point is located is a densely built-up area. When the fault point is located in a densely built-up area, the ground location of the second fiber optic fault point is obtained by combining a GIS map with the cable length of the fiber optic fault point, resulting in a more accurate ground location. Since fiber optic maintenance is difficult in densely built-up areas, even small positional deviations can significantly increase the difficulty of fiber optic maintenance. Therefore, accurately locating the corresponding ground location of the fault point using a GIS map combined with the cable length of the fiber optic fault point can effectively improve the convenience and efficiency of cable maintenance. When the fault point is located in a sparsely built-up area, the maintenance environment is relatively relaxed, and fiber optic maintenance is less difficult. The cable length of the fiber optic fault point is input into a pre-trained historical fault data model to obtain the ground location of the third fiber optic fault point. This improves the positioning efficiency while ensuring that the positioning accuracy of the fiber optic fault location meets maintenance requirements.

[0071] Optionally, obtaining the ground location of the second fiber optic fault point based on the GIS map and the cable length of the fiber optic fault point includes:

[0072] Obtain the GIS map, wherein the GIS map includes multiple marker points for indicating the ground location directly above the fiber optic line;

[0073] The ground location of the GIS fault point is obtained based on the GIS map and the length of the fiber optic fault point cable.

[0074] The target marker location is obtained by filtering the marker points based on the ground location of the GIS fault point;

[0075] Vibration attenuation information of the optical fiber is obtained by applying vibration at the target identification location;

[0076] The length of the cable at the marked point is obtained based on the vibration fiber attenuation information.

[0077] The ground location of the second optical fiber fault point is obtained based on the cable length of the marker point and the cable length of the optical fiber fault point.

[0078] Specifically, a GIS map is a technological tool used to collect, store, analyze, and display geographic data and information. The GIS map contains fiber optic cable length information, and the location of the relevant position on the GIS map is determined by the cable length of the fiber optic fault point. The target marker position is located by filtering for the nearest marker point. Here, the marker point represents the ground position directly above the fiber optic cable, pre-set using fiber optic route diagrams. Vibration is applied to the target marker position to obtain the fiber optic attenuation information, and the cable length from the input end to the marker point is obtained. Based on the marker point cable length and the fiber optic fault point cable length, the ground position of the second fiber optic fault point is determined.

[0079] In this optional embodiment, combining a GIS map can more quickly identify the ground location of the fault point, and the results obtained are more accurate, avoiding deviations caused by differences in cable length and ground location.

[0080] Optionally, obtaining the ground location of the second optical fiber fault point based on the length of the marker cable and the length of the optical fiber fault point cable includes:

[0081] The difference in cable length at the marker point is obtained based on the cable length at the marker point and the cable length at the fiber optic fault point.

[0082] When the difference in cable length between the marked points is less than or equal to a preset threshold, the target marked location is taken as the ground location of the second optical fiber fault point.

[0083] When the difference in cable length between the marker points is greater than the preset threshold, the cable offset value is obtained based on the difference in cable length between the marker points.

[0084] The ground location of the second optical fiber fault point is obtained by correcting the target identifier position using the cable offset value.

[0085] Specifically, by comparing the difference between the cable length of the marker point and the cable length of the fiber optic fault point with a preset threshold, it is determined whether the marker point is a fiber optic fault point. If the difference is too large, the cable offset value is obtained by multiplying the difference in cable length of the marker point by a correlation coefficient. The target marker position is then corrected using the cable offset value to obtain the ground position of the second fiber optic fault point.

[0086] In this optional embodiment, considering that the location of the marker point may be some distance from the fault location, or that the location of the fiber optic cable may deviate from the drawing due to the extended installation time, the ground location of the second fiber optic fault point is obtained by calculating the cable offset value to correct the target marker position.

[0087] Optionally, determining the fault zone based on the ground location of the first fiber optic fault point includes:

[0088] Obtain geographic information of the area surrounding the fiber optic cable laying location, wherein the geographic information includes geographic location and geographic imagery;

[0089] The geographic image is divided into multiple sub-regions based on the geographic location;

[0090] The building density is obtained by performing image recognition on all the sub-regions respectively;

[0091] When the building density is greater than a preset building density threshold, the sub-zone is designated as the building-dense area.

[0092] When the building density is less than or equal to the preset building density threshold, the sub-zone is designated as the building sparse zone.

[0093] Specifically, the geographic image is evenly divided into multiple sub-regions according to a preset size, and each sub-region can be a square area. The image is preprocessed, such as denoising and contrast enhancement, to improve recognition accuracy, and features of each building are extracted to obtain the building density.

[0094] In this optional embodiment, by collecting geographical information about the area surrounding the fiber optic cable laying and using image feature extraction technology, an index of building density in the image is obtained. Based on this index, different fiber optic fault location methods are applied to different levels of the area, which is more in line with actual conditions.

[0095] Optionally, obtaining the ground location of the first fiber optic fault point based on the standard reference point cable length, the standard reference point ground location, and the fiber optic fault point cable length includes:

[0096] Obtain the cable length of the standard reference point and the ground position of the standard reference point;

[0097] The ratio of the standard reference point cable length is obtained based on the standard reference point cable length and the fiber optic fault point cable length.

[0098] The ground location of the first optical fiber fault point is obtained by using the ratio of the cable length of the standard reference point and the ground location of the standard reference point.

[0099] Optionally, obtaining the cable length of the standard reference point and the ground position of the standard reference point includes:

[0100] Applying external force to bend the cable at a standard reference point yields information on the attenuation of the bent optical fiber. The standard reference point is used to represent one of a plurality of reference points spaced at preset distances along the fiber optic laying position.

[0101] The cable length of the standard reference point and the ground location of the standard reference point are obtained through the attenuation information of the bent optical fiber.

[0102] Specifically, external force is applied to the standard reference point to bend the cable to obtain the bending fiber attenuation information. When the standard reference point bends, the obtained bending fiber attenuation information will form an observable abnormal attenuation at the bending point. The length of the fiber optic cable from the input end to the standard reference point can be obtained through the abnormal attenuation.

[0103] Optionally, the method for constructing the pre-trained historical fault data model includes:

[0104] Obtain a historical fault dataset, wherein the historical fault dataset includes the ground location of the historical fault point and the cable length of the historical fault point;

[0105] An initial training model is obtained by training a neural network model using the ground location of the historical fault point and the cable length of the historical fault point.

[0106] If the model accuracy of the initial training model does not meet the model accuracy requirement, the historical fault dataset is re-acquired and trained until the model accuracy requirement is met, thus obtaining the pre-trained historical fault data model.
