In view of the problems existing in the above-mentioned related technologies, this embodiment provides a method, device, electronic device and storage medium for locating optical fiber faults.

As shown in FIG1 , an optical fiber fault location method provided by an embodiment of the present invention includes:

Step 110: Collect original optical fiber attenuation information through an optical fiber interferometer.

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

Step 120: obtaining a cable length at a fiber fault point according to the original fiber attenuation information, wherein the cable length at the fiber fault point is used to represent a cable length from a fiber input end to a fiber fault point.

Specifically, a suitable wavelet basis function is selected to perform wavelet decomposition on the original optical fiber attenuation information to obtain the decomposed original optical 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 perform quantization processing on the decomposed original optical fiber attenuation information to obtain the quantized original optical fiber attenuation information; noise reduction processing is performed on the quantized original optical fiber attenuation information to obtain the noise-reduced original optical fiber attenuation information; singularity analysis is performed on the noise-reduced original optical fiber attenuation information by performing wavelet decomposition to obtain a singular point; and the cable length of the optical fiber fault point is obtained according to the singular point, wherein the singular point is used to indicate the location where the fault occurs.

Step 130, obtaining the ground position of the first optical fiber fault point according to the standard reference point cable length, the standard reference point ground position and the optical fiber fault point cable length.

Specifically, an external force is applied to a preset standard reference point to bend the cable, which drives the optical fiber in the cable to bend, thereby changing the optical fiber attenuation at the standard reference point, and measuring the cable length from the optical fiber input end to the standard reference point to obtain the standard reference point cable length. With the standard reference point cable length and the ground position of the standard reference point as reference, the cable length of the optical fiber fault point is converted to the ground position of the first optical fiber fault point.

Step 140: determining the fault point partition according to the ground position of the first optical fiber fault point, wherein the fault point partition includes a building-dense area and a building-sparse area.

Specifically, the area where the optical fiber fault occurs is located by locating the ground position of the first optical fiber fault point, and the overall area is divided into a densely built area and a sparsely built area. Among them, the densely built area is an area with relatively dense buildings, and it is difficult to repair the direct buried optical fiber fault point.

Step 151, when the fault point is partitioned into the densely built area, the ground position 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.

Specifically, a fiber optic line drawing is obtained, a GIS map is generated according to the fiber optic line drawing, and a fiber optic line map is drawn.

Step 152: When the fault point is partitioned into the building-sparsely populated area, the cable length of the optical fiber fault point is input into a pre-trained historical fault data model to obtain a ground position of a third optical fiber fault point.

Specifically, the pre-trained historical fault data model can be trained by a neural network model, which can learn and recognize complex patterns and relationships and is suitable for a variety of tasks such as classification, regression and generation.

In this embodiment, the cable length of the optical fiber fault point is obtained according to the optical fiber attenuation information, and the ground position of the first optical fiber fault point is first determined by the cable length of the standard reference point and the ground position of the standard reference point. The ground position of the first optical fiber fault point is used to determine whether the area where the fault point is located is a densely built area. When the fault point is located in a densely built area, the ground position of the second optical fiber fault point is obtained by combining the GIS map with the cable length of the optical fiber fault point, and the ground position of the fault point is more accurate. Since optical fiber maintenance in densely built areas is difficult, even a small position deviation may significantly increase the difficulty of optical fiber maintenance. Therefore, the corresponding ground position of the fault point is accurately located by combining the GIS map with the cable length of the optical fiber fault point, which can effectively improve the convenience and efficiency of cable maintenance. When the fault point is located in a sparsely built area, the maintenance environment is relatively loose and the difficulty of optical fiber maintenance is relatively small. The cable length of the optical fiber fault point is input into the pre-trained historical fault data model to obtain the ground position of the third optical fiber fault point. Under the premise of ensuring that the positioning accuracy of the optical fiber fault position meets the maintenance requirements, the positioning efficiency is improved.

Optionally, obtaining the ground position of the second optical fiber fault point according to the GIS map and the cable length of the optical fiber fault point includes:

The ground position of the second optical fiber fault point is obtained according to the cable length of the identification point and the cable length of the optical fiber fault point.

Specifically, GIS map is a technical tool for collecting, storing, analyzing and displaying geographic data and geographic information. The GIS map contains information on the length of optical fiber cables, and the relevant position in the GIS map is located by the cable length of the optical fiber fault point. The target identification position is located by screening the nearest identification point near the position. The identification point here represents the ground position directly above the optical fiber, which is pre-set through the optical fiber line drawing. By applying vibration to the target identification position, the vibration fiber attenuation information is obtained, and the identification point cable length from the input end to the identification point is obtained. According to the identification point cable length and the optical fiber fault point cable length, the ground position of the second optical fiber fault point is obtained.

In this optional embodiment, by combining with the GIS map, the ground location of the fault point can be identified more quickly, and the result obtained is more accurate, avoiding the deviation caused by the difference in cable length and ground location.

Optionally, obtaining the ground position of the second optical fiber fault point according to the cable length of the identification point and the cable length of the optical fiber fault point includes:

Obtaining a difference in the length of the cable at the identification point according to the length of the cable at the identification point and the length of the cable at the optical fiber fault point;

When the cable length difference of the identification point is less than or equal to a preset threshold, the target identification position is used as the ground position of the second optical fiber fault point;

When the cable length difference of the identification point is greater than the preset threshold, a cable offset value is obtained according to the cable length difference of the identification point;

The target identification position is corrected by the cable offset value to obtain the ground position of the second optical fiber fault point.

Specifically, by comparing the difference between the cable length of the identification point and the cable length of the optical fiber fault point with a preset threshold, it is determined whether the identification point is a fiber fault point. If the difference between the two is too large, the cable offset value is obtained by multiplying the cable length difference of the identification point by the correlation coefficient, and the target identification position is corrected by using the cable offset value to obtain the ground position of the second optical fiber fault point.

In this optional embodiment, considering that the position of the marking point may be a certain distance from the fault position, or the position of the optical fiber cable may deviate from the drawing due to the increase in the fiber optic cable burial time, the target marking position is corrected by calculating the cable offset value to obtain the ground position of the second optical fiber fault point.

Optionally, the determining the fault point partition according to the ground position of the first optical fiber fault point includes:

Acquire geographic information around the optical fiber laying location, wherein the geographic information includes a geographic location and a geographic image;

splitting the geographic image into a plurality of sub-regions according to the geographic location;

Performing image recognition on all the sub-districts to obtain building density;

When the building density is greater than a preset building density threshold, the sub-district is used as the building density area;

When the building density is less than or equal to the preset building density threshold, the sub-area is used as the building sparse area.

Specifically, the geographic image is evenly divided into a plurality of sub-areas according to a preset size, and the sub-areas may be square areas. The image is preprocessed, such as denoising, contrast enhancement, etc., to improve recognition accuracy, and the features of each building are extracted, and the building density is obtained through the building features.

In this optional embodiment, geographic information of the optical fiber laying surroundings is collected and image feature extraction technology is used to obtain the building density index in the image. Different optical fiber fault location acquisition methods are used to classify the regions according to the index, which is more in line with the actual situation.

Obtaining the standard reference point cable length and the standard reference point ground position;

Obtaining a standard reference point cable length ratio according to the standard reference point cable length and the optical fiber fault point cable length;

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

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

The cable length of the standard reference point and the ground position of the standard reference point are obtained through the bent optical fiber attenuation information.

Specifically, an external force is applied to the standard reference point to bend the cable to obtain the bent optical fiber attenuation information. When the standard reference point is bent, the obtained bent optical fiber attenuation information will form an observable abnormal attenuation at the bending point, and the length of the optical fiber cable from the input end to the standard reference point can be obtained through the abnormal attenuation.

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