[0002] Optical cables are communications cable assemblies that utilize one or more optical fibers enclosed in a sheath as the transmission medium and can be used individually or in groups. Routing is the network-wide process that determines the end-to-end path. Existing transmission networks must adhere to the principle of multi-route protection for critical services. Therefore, identifying and eliminating common routing issues within optical cables is one of the most important tasks in transmission network optimization and management.

[0026] The acquisition, storage, use, processing and the like of data in the technical solutions of the present application comply with relevant provisions of national laws and regulations.

[0027] In the related art, the current method for generating same-route identification information mainly uses basic data such as optical paths, optical cables, and pipelines to automatically analyze the network route, and to find and locate the same-route problem in the communication network. In this method, it is necessary to pre-collect sufficient and perfect optical cable basic information, and to perform identification analysis according to a large data set, which results in too low identification efficiency.

[0028] The present application provides a method, device, equipment and storage medium for generating same-route identification information. In the method for generating same-route identification information provided by the present application, a first data image of a first core and a second data image of a second core are acquired, and then the first data image and the second data image are converted into binary sequences based on a hash algorithm, wherein the binary sequences include a first sequence and a second sequence. In this way, the data image of the core can be directly collected without pre-collecting the optical cable basic information, and the binary sequence generated according to the hash algorithm is used to represent the first data image and the second data image, which overcomes the problems of too large data set and too complex processing and calculation. Finally, the Hamming distance between the first sequence and the second sequence is determined according to the first sequence and the second sequence, and the same-route identification information between the first core and the second core is generated according to the Hamming distance. In this way, the same-route identification information finally generated by the present application can be generated by simply analyzing the binary sequence, without identification analysis according to a large data set and without pre-collecting sufficient and perfect optical cable basic information, thereby improving the efficiency of same-route identification.

[0029] The specific embodiments of the method, device, equipment and storage medium for generating same-route identification information provided by the present application will be introduced below. First, the method for generating same-route identification information will be introduced.

[0030] Figure 1A flowchart of a method for generating same-route identification information is provided, the method for generating same-route identification information is applied to a server, and the method can include the following steps S101-S104.

[0031] S101, a first data image of a first fiber core and a second data image of a second fiber core are obtained.

[0032] The first fiber core and the second fiber core are fiber cores to be identified whether a same-route problem occurs. For example, in a case where it is necessary to identify whether a same-route problem occurs between an A fiber core and a B fiber core, the A fiber core can be taken as the first fiber core, and the B fiber core can be taken as the second fiber core.

[0033] The data image is a fiber curve image representing a relationship between return light intensity and fiber length, wherein the abscissa is the fiber length, and the ordinate is the return light intensity. Specifically, the first data image is a fiber curve image representing a relationship between return light intensity and fiber length in the first fiber core, and the second data image is a fiber curve image representing a relationship between return light intensity and fiber length in the second fiber core.

[0034] For example, the server can collect a dot matrix composed of attenuation data of the first fiber core and the second fiber core through an optical time-domain reflectometer (OTDR), and then present and save the dot matrix through the corresponding first data image and second data image. Specifically, the first data image and the second data image can be collected through a board card supporting the OTDR function, or collected through direct testing of the OTDR instrument.

[0035] S102, based on a hash algorithm, the first data image and the second data image are converted into a binary sequence, and the binary sequence includes a first sequence and a second sequence.

[0036] The hash algorithm is an algorithm for mapping a value of any length to a binary value of a shorter fixed length. The binary sequence is a sequence generated after the data image is binarized.

[0037] The first sequence is a binary sequence corresponding to the first data image, and the first sequence includes a plurality of first results. The first result is a result generated by performing gray-scale binarization on each first pixel point in the first data image. The first pixel point is a pixel point in the first data image that needs to be processed by gray-scale binarization.

[0038] The second sequence is a binary sequence corresponding to the second data image, and the second sequence includes a plurality of second results. The second result is a result generated by performing gray-scale binarization on each second pixel point in the second data image. The second pixel point is a pixel point in the second data image that needs to be processed by gray-scale binarization.

[0039] For example, after collecting the first data image and the second data image, the server performs grayscale binarization processing on multiple first pixels in the first data image based on a hash algorithm to generate multiple first results, and generates a first sequence based on the multiple first results. Simultaneously, the server performs grayscale binarization processing on multiple second pixels in the second data image based on a hash algorithm to generate multiple second results, and generates a second sequence based on the multiple second results.

[0040] S103: Determine a Hamming distance between the first sequence and the second sequence according to the first sequence and the second sequence.

[0041] The Hamming distance is the number of differences between the first result in the first sequence and the corresponding second result in the second sequence. For example, let d(x, y) represent the Hamming distance between two sequences x and y. Perform an XOR operation on the characters at corresponding positions in the two sequences and count the number of 1s (i.e., the number of characters at corresponding positions in the two sequences that differ). This number is the Hamming distance.

[0042] For example, after obtaining the first sequence and the second sequence, the server compares the first result and the second result at corresponding positions in the two sequences in sequence to determine the number of differences between the first result and the second result. This number is the Hamming distance.

[0043] As an example, a first sequence A = {1, 0, 0, 1, 1} and a second sequence B = {1, 0, 1, 1, 1}. The first result and the second result at corresponding positions in sequences A and B are compared sequentially, and the number of differences between the first result and the second result is determined to be 1, thereby determining that the Hamming distance is 1.

[0044] S104 : When the Hamming distance is zero, information is generated that the first fiber core and the second fiber core have the same route throughout.

[0045] After determining the Hamming distance, the server determines whether the optical path corresponding to the first fiber core and the optical path corresponding to the second fiber core share the same route throughout their entirety based on the Hamming distance. If the Hamming distance is zero, it is determined that the first fiber core and the second fiber core share the same route throughout their entirety, and information indicating that the first fiber core and the second fiber core share the same route throughout their entirety is generated. If the Hamming distance is not zero, it is determined that the first fiber core and the second fiber core do not share the same route throughout their entirety, and information indicating that the first fiber core and the second fiber core do not share the same route throughout their entirety is generated.

[0046] Through this embodiment, the first data image of the first fiber core and the second data image of the second fiber core are obtained, and then based on the hash algorithm, the first data image and the second data image are converted into a binary sequence, wherein the binary sequence includes a first sequence and a second sequence. In this way, the data image of the fiber core can be directly collected without the need to collect basic information of the optical cable in advance. At the same time, the binary sequence generated according to the hash algorithm is used to represent the first data image and the second data image, thereby overcoming the problems of too large a data set and more complex processing calculations. Finally, based on the first sequence and the second sequence, the Hamming distance between the first sequence and the second sequence is determined, and the same-route identification information between the first fiber core and the second fiber core is generated based on the Hamming distance. In this way, the same-route identification information finally generated by the embodiment of the present application can be generated only by simply analyzing the binary sequence, without the need to perform identification analysis based on a large data set, and without the need to collect sufficiently complete basic information of the optical cable in advance, thereby improving the efficiency of same-route identification.

[0047] In one embodiment, the first sequence includes a first receiving sequence and a first sending sequence, and the second sequence includes a second receiving sequence and a second sending sequence. The above method for generating the same-route identification information may further include:

[0048] When the Hamming distance is not zero, determining a first change time of the first fiber core according to the first receiving sequence and the first transmitting sequence, where the first change time is a test time corresponding to a most recent change in the first result of the first receiving sequence and the first transmitting sequence;

[0049] Determining a second change time of the second fiber core according to the second receiving sequence and the second sending sequence, where the second change time is a test time corresponding to a most recent change in the second results of the second receiving sequence and the second sending sequence;

[0050] In a case where the first change time and the second change time are the same, generating a first change value set for the first fiber core and a second change value set for the second fiber core based on the first result and the second result, the first change value set including at least one first change value, the first change value being used to characterize a degree of change in the intensity of returned light in a region where a first pixel point in the first data image corresponding to the first change time is located, and the second change value set including at least one second change value, the second change value being used to characterize a degree of change in the intensity of returned light in a region where a second pixel point in the second data image corresponding to the second change time is located;

[0051] Generate a change difference value set based on the first change value set and the second change value set, wherein the change difference value set includes at least one change difference value, and the change difference value is the difference between any first change value in the first change value set and any second change value in the second change value set;

[0052] In a case where at least one of the change difference values in the change difference value set is less than a preset threshold value, information that the first core and the second core exist local same routing is generated.

[0053] The first receiving sequence is a binary sequence corresponding to a data image acquired by the first core along the receiving direction, and the first sending sequence is a binary sequence corresponding to a data image acquired by the first core along the sending direction.

[0054] The second receiving sequence is a binary sequence corresponding to a data image acquired by the second core along the receiving direction, and the second sending sequence is a binary sequence corresponding to a data image acquired by the second core along the sending direction.

[0055] The first change time is a test time corresponding to a case where the last returned light intensity values of the first receiving sequence and the first sending sequence are different, the second change time is a test time corresponding to a case where the last returned light intensity values of the second receiving sequence and the second sending sequence are different, and the returned light intensity value is a corresponding longitudinal coordinate value in the data image.

[0056] For example, the server compares the first receiving sequence and the first sending sequence in a case where the Hamming distance is not zero, determines a test time corresponding to a case where the first result of the first receiving sequence and the first sending sequence changes for the last time. As an example, the first sequence A includes the first receiving sequence A1 and the first sending sequence A2. A1={1, 0, 0, 1, 1}, A2={1, 0, 1, 1, 1}, and it is determined that the time corresponding to the case where the first receiving sequence A1 and the first sending sequence A2 change for the last time is the third first result by comparison.

[0057] Meanwhile, the second receiving sequence and the second sending sequence are compared, and a test time corresponding to a case where the second result of the second receiving sequence and the second sending sequence changes for the last time is determined. As an example, the second sequence B includes the second receiving sequence B1 and the second sending sequence B2. B1={1, 0, 0, 1, 1}, B2={1, 0, 1, 1, 1}, and it is determined that the time corresponding to the case where the second receiving sequence B1 and the second sending sequence B2 change for the last time is the third second result by comparison.

[0058] In a case where the first change time and the second change time are the same, a plurality of first change values are generated according to a plurality of changed first results corresponding to the first change time, each first change value is collected into a first change value set, a plurality of second change values are generated according to a plurality of changed second results corresponding to the second change time, and each second change value is collected into a second change value set.

[0059] When the first change value set and the second change value set are determined, the difference between any first change value in the first change value set and any second change value in the second change value set is calculated to obtain multiple change differences, and the individual change differences are grouped into a change difference set.

[0060] Each change difference value in the change difference value set is compared with a preset threshold to determine whether the optical path corresponding to the first fiber core and the optical path corresponding to the second fiber core have a local co-routing. If at least one change difference value in the change difference value set is less than the preset threshold, it is determined that the first fiber core and the second fiber core have a local co-routing, and information that the first fiber core and the second fiber core have a local co-routing is generated.

[0061] As an example, a first change time corresponds to two changed first results, and two first change values, P1 and P2, are determined based on the two first results. P1 and P2 are grouped into a first change value set P. A second change time corresponds to two changed second results, and two second change values, Q1 and Q2, are determined based on the two second results. Q1 and Q2 are grouped into a second change value set Q. The difference between each first change value in the first change value set P and each second change value in the second change value set Q is then calculated to obtain four change difference values ​​K1, K2, K3, and K4. The four change differences are compared with a preset threshold. If at least one change difference is less than the preset threshold, it is determined that the first fiber core and the second fiber core have a local co-routing, and information that the first fiber core and the second fiber core have a local co-routing is generated.

[0062] Through this embodiment, after determining that there is no full co-routing between the first fiber core and the second fiber core, by determining the first change value set and the second change value set when the first change time and the second change time are the same, it is possible to further determine whether there is a local co-routing between the first fiber core and the second fiber core.

[0063] In one embodiment, the first data image includes a first received data image and a first sent data image, the second data image includes a second received data image and a second sent data image, the first result includes a first received result and a first sent result, and the second result includes a second received result and a second sent result;

[0064] In a case where the first change time and the second change time are the same, generating a first change value set for the first fiber core and a second change value set for the second fiber core based on the first result and the second result, including:

[0065] Obtain each first area corresponding to the first change time and each second area corresponding to the second change time, where the first area is the area where the first pixel point corresponding to the first reception result or the first transmission result of the first change time is located, and the second area is the area where the second pixel point corresponding to the second reception result or the second transmission result of the second change time is located;

[0066] Obtaining a first reception value of a first reception data image corresponding to a first reception result and a first transmission value of a first transmission data image corresponding to a first transmission result in each first area, and a second reception value of a second reception data image corresponding to a second reception result and a second transmission value of a second transmission data image corresponding to a second transmission result in each second area, wherein the first reception value, the first transmission value, the second reception value, and the second transmission value are all numerical values ​​of return light intensities in corresponding data images;

[0067] A first set of change values ​​for the first core is generated based on the difference between the first reception value and the first transmission value in each first region, and a second set of change values ​​for the second core is generated based on the difference between the second reception value and the second transmission value in each second region.

[0068] The first received data image is associated with the first received sequence, the first sent data image is associated with the first sent sequence, the first received result is the first result in the first received sequence, and the first sent result is the first result in the first sent sequence.

[0069] The second received data image is associated with the second receive sequence, the second sent data image is associated with the second send sequence, the second receive result is the second result in the second receive sequence, and the second send result is the second result in the second send sequence.

[0070] For example, if the first change time and the second change time are the same, the server obtains the first received result or the first sent result that has changed corresponding to the first change time, and determines the first region based on the first received result or the first sent result. As an example, if two first received results have changed corresponding to the first change time, namely V1 and V2, the first regions W1 and W2 are determined based on the horizontal coordinates of the first received data image corresponding to V1 and V2, respectively.

[0071] Furthermore, the server obtains the changed second reception result or second transmission result corresponding to the second change time, and determines the second region based on the second reception result or second transmission result. As an example, if two second reception results corresponding to the second change time have changed, namely V3 and V4, the second regions W3 and W4 are determined based on the horizontal coordinates of the first received data image corresponding to V3 and V4, respectively.

[0072] Obtain the corresponding vertical coordinate values ​​of each pixel point in the first area W1 and W2 in the corresponding first received data image and the corresponding vertical coordinate values ​​in the first sent data image, as well as the corresponding vertical coordinate values ​​of each pixel point in the second area W3 and W4 in the corresponding second received data image and the corresponding vertical coordinate values ​​in the second sent data image.

[0073] The difference between the vertical coordinate values ​​corresponding to each pixel point in the first area W1 and W2 in the corresponding first received data image and the vertical coordinate values ​​corresponding to the first transmitted data image is calculated to generate a first change value set of the first fiber core; the difference between the vertical coordinate values ​​corresponding to each pixel point in the second area W3 and W4 in the corresponding second received data image and the vertical coordinate values ​​corresponding to the second transmitted data image is calculated to generate a second change value set of the second fiber core.

[0074] Through this embodiment, by determining each first area corresponding to the first change time and each second area corresponding to the second change time, a first change value set of the first fiber core and a second change value set of the second fiber core are further generated, which helps to subsequently determine whether there is a local common route between the first fiber core and the second fiber core based on the first change value set and the second change value set.

[0075] In one embodiment, a first set of changed values ​​for the first core is generated based on the difference between the first received value and the first transmitted value in each first region, and a second set of changed values ​​for the second core is generated based on the difference between the second received value and the second transmitted value in each second region, satisfying the following formula 1:

[0076]

[0077] Where z is the first change value or the second change value, x is the starting position of the first area or the second area, y is the ending position of the first area or the second area, and z new is the first received value or the second received value, z old is the first sending value or the second sending value, and n is the number of first pixels in the first area or the number of second pixels in the second area.

[0078] Through this embodiment, the first change value set of the first fiber core and the second change value set of the second fiber core are determined according to Formula 1, which helps to subsequently determine whether there is a local co-routing between the first fiber core and the second fiber core based on the first change value set and the second change value set.

[0079] In one embodiment, the above S102 specifically includes:

[0080] setting the first data image and the second data image into a target format;

[0081] Acquire a first grayscale of a first pixel in a first data image in a target format, and a second grayscale of a second pixel in a second data image in a target format;

[0082] Comparing a first grayscale of a first pixel with a first average grayscale, and generating a first sequence based on the comparison result;

[0083] The second grayscale of the second pixel is compared with the second average grayscale, and a second sequence is generated based on the comparison result.

[0084] The first pixel is each pixel in the first data image, and the second pixel is each pixel in the second data image. The first grayscale is the grayscale of the first pixel, and the second grayscale is the grayscale of the second pixel. The first average grayscale is the average grayscale in the first data image, and the second average grayscale is the average grayscale in the second data image.

[0085] For example, the server first preprocesses the first data image and the second data image by determining the target size of the image, filtering out high-frequency information, reducing the image to a size of 32*32, and retaining 1024 pixels, thereby setting the first data image and the second data image to the target format.

[0086] Then, the first grayscale corresponding to each of the 1024 pixels in the first data image and the second grayscale corresponding to each of the 1024 pixels in the second data image are obtained. Each first grayscale is then compared with the average grayscale of the first data image. If the first grayscale is greater than the average grayscale of the first data image, the value is 1; otherwise, the value is 0. Each second grayscale is compared with the average grayscale of the second data image. If the second grayscale is greater than the average grayscale of the second data image, the value is 1; otherwise, the value is 0.

[0087] The results generated after comparing 1024 pixel points in the first data image are spliced ​​together to generate a first sequence; the results generated after comparing 1024 pixel points in the second data image are spliced ​​together to generate a second sequence.

[0088] Through this embodiment, the first sequence and the second sequence are generated according to the first data image and the second data image, which helps to directly identify whether they are the same route according to the first sequence and the second sequence, thereby reducing the amount of calculation and improving the recognition speed.

[0089] In one embodiment, after S101, the following steps may also be included:

[0090] Determining image names of the first data image and the second data image according to the names of the transmission optical paths of the first fiber core and the second fiber core, wherein the image names are associated with the names of the transmission optical paths;

[0091] The test time, the return light intensity value, the optical fiber length value, and the event point position corresponding to the first data image and the second data image are acquired respectively, and the event point includes a fusion loss point and a joint loss point;

[0092] The first data set is generated according to the first data image and the corresponding test time, return light intensity value, optical fiber length value, and event point position, and the second data set is generated according to the second data image and the corresponding test time, return light intensity value, optical fiber length value, and event point position;
