Before describing the line inspection method provided by the embodiment of the present application in detail, the implementation environment and application field Jing Jinhang of the embodiment of the present application will be described.
First, an application scenario of the embodiment of the present application is described.
The line inspection method of the embodiment of the application is applied to the scene of inspecting the state of the line connected with the network element equipment. In the related art, when checking the state of a line connected to a network element device, a management device (such as a server) is required to acquire alarm information from the network element device, and determine the line connected to the network element device in a signal transmission network according to the alarm information. Then, the management device checks the state of the line to which the network element device is connected.
In summary, in the current technical solution, the management device can only check the status of the line connected to the network element device in the signal transmission network when the network element device in the signal transmission network is already affected. Therefore, how to predict the state of the line connected to the network element device is a technical problem to be solved.
In order to solve the above problems, an embodiment of the present application provides a method for inspecting a line, where an inspection device obtains a historical light attenuation value of a line to be inspected, and determines a light attenuation threshold according to the historical light attenuation value. And then, the checking device determines whether a light attenuation value larger than the light attenuation threshold exists in a section of historical light attenuation value of the line to be checked, which is adjacent to the current moment, according to the light attenuation threshold. If so, the inspection device determines that the line to be inspected has a degradation trend, and if not, the inspection device determines that the line to be inspected does not have a degradation trend. That is, the inspection apparatus may predict whether or not the line to be inspected has a degradation tendency in a future period based on the historical light attenuation value of the line to be inspected. In this way, a prediction of the state of the line can be achieved.

After that, the server 101 may receive the optical power value from the network element device 102 and the optical power value from the network element device 103, calculate a difference between the two optical power values, and determine an optical attenuation value of the optical fiber line between the network element device 102 and the network element device 103. After that, the server 101 may predict the state of the optical fiber line between the network element device 102 and the network element device 103 according to the optical attenuation value of the optical fiber line between the network element device 102 and the network element device 103.
The server (e.g., server 101) may be a physical server or a cloud server.

S204, the server generates first prediction information.
The first prediction information is used for indicating that the first line has a degradation trend in a third preset period, and the third preset period is later than the first preset period.
In one possible design, the first prediction information may include an identification of the first line, a third preset period of time, and a first identification indicating that there is a degradation trend.
Illustratively, the first predictive information includes 20Y3v94, 2022, 12, 27, 11 am, 57 minutes and 101. Wherein 20Y3v94 is an identification of the first line, 101 is used to indicate that there is a degradation trend.
The technical scheme provided by the embodiment at least has the advantages that the server can acquire first information and second information, the first information comprises at least one first light attenuation value, the first light attenuation value is a light attenuation value of a first circuit in a first preset period, the second information comprises at least one second light attenuation value, the second light attenuation value is a light attenuation value of the first circuit in a second preset period, and the second preset period is earlier than the first preset period. The server may then process the at least one second light decay value to generate a first threshold, the first threshold being an average between the at least one second light decay value. The server may then determine whether there is a light decay value of the at least one first light decay value that is greater than a first threshold. If the server determines that the light attenuation value larger than the first threshold exists in the at least one first light attenuation value, the server generates first prediction information, wherein the first prediction information is used for indicating that the first line has a degradation trend in a third preset period, and the third preset period is later than the first preset period. That is, the server may predict whether the first line has a degradation tendency in a future period based on the historical light degradation value of the first line. In this way, a prediction of the state of the line can be achieved.
In some embodiments, if the server determines that there is no light attenuation value greater than the first threshold value in the at least one first light attenuation value, the server generates third prediction information, where the third prediction information is used to indicate that the first line has no degradation tendency within a third preset period.
In some embodiments, the server may process the at least one first light decay value to generate a fifth light decay value, the fifth light decay value being an average between the at least one first light decay value. And then, the server can determine a sixth light attenuation value in the first information according to the second preset threshold, wherein the sixth light attenuation value is at least one light attenuation value smaller than the second preset threshold in the first light attenuation value. And then, the server modifies the sixth light attenuation value in the first information into a fifth light attenuation value to generate fourth information, wherein the light attenuation values in the fourth information are all larger than or equal to a second preset threshold value. Then, the server determines whether there is a light decay value greater than the first threshold in the fourth information.
In the embodiment of the application, if the server determines that the fourth information has the light attenuation value greater than the first threshold value, the server generates the first prediction information.
Optionally, if the server determines that the fourth information does not have a light attenuation value greater than the first threshold, the server generates third prediction information.
In one possible implementation, when the server processes the at least one first light attenuation value, the server may arrange the at least one first light attenuation value in order from the top to the bottom to generate the target sequence. Then, the server may delete the first light attenuation values of the first preset number and the second light attenuation values of the second preset number in the first preset number in the target sequence, and generate at least one sixth light attenuation value. The server may then process the at least one sixth light decay value to generate a fifth light decay value, the fifth light decay value being an average between the at least one sixth light decay value.
Illustratively, the at least one first light attenuation value comprises 12 db/km, 23 db/km, 19 db/km and 20 db/km, and the server generates the target sequence of 12 db/km, 19 db/km, 20 db/km, 23 db/km after arranging the at least one first light attenuation value in order from the top. If the first preset number is 1 and the second preset number is 1, the at least one sixth light attenuation value generated by the server comprises 19 dB/km and 20 dB/km, and the generated fifth light attenuation value is 19 dB/km.
In one possible implementation manner, after the server determines the seventh light attenuation value in the first information, the server may sort the light attenuation values in the first information according to a first preset time corresponding to each light attenuation value in the first information, so as to generate fifth information. Then, the server may determine a third set according to the first preset time and the second preset number threshold corresponding to the seventh light attenuation value in the fifth information, where the third set includes consecutive seventh light attenuation values in the fifth information, and the number of the seventh light attenuation values in the third set is greater than the second preset number threshold. And then, the server modifies the seventh light attenuation value in the third set in the fifth information into a fifth light attenuation value to generate fourth information, wherein the light attenuation values in the fourth information are all larger than or equal to a second preset threshold value.
The first information includes, by way of example, 10 db/km, 33 db/km, 31 db/km, 7 db/km, 9 db/km, and 6 db/km, with a fifth light attenuation value of 16 db/km. The first preset time corresponding to 10 dB/kilometers is 8 am, the first preset time corresponding to 33 dB/kilometers is 9 am, the first preset time corresponding to 31 dB/kilometers is 10 am, the first preset time corresponding to 7 dB/kilometers is 11 am, the first preset time corresponding to 9 dB/kilometers is 1 pm, and the first preset time corresponding to 6 dB/kilometers is 12 am. The server arranges the light attenuation values in the first information to generate fifth information, wherein the fifth information is 10 db/km, 33 db/km, 31 db/km, 7 db/km, 6 db/km, 9 db/km. If the second preset threshold is 11 db/km and the second preset number threshold is 2, the server determines that the third set includes 7 db/km, 6 db/km, 9 db/km and generates fourth information of 10 db/km, 33 db/km, 31 db/km, 16 db/km.
It can be understood that the server can modify the abnormal light attenuation value in the first information by modifying the sixth light attenuation value in the first information into the fifth light attenuation value, so that the influence of the abnormal light attenuation value in the first information on the prediction result is avoided, and the accuracy of the prediction result is improved.
In some embodiments, as shown in FIG. 3, the inspection method of the line may further include, prior to S201, S301-S303
S301, the server acquires at least one piece of third information.
The third information may include at least one third light attenuation value, where the third light attenuation value is a light attenuation value of the second line within the first preset period, one third information corresponds to one second line, and one first preset time corresponds to one third light attenuation value.
S302, for each piece of third information in the at least one piece of third information, the server performs variable point detection on at least one piece of third light attenuation value in the third information, and determines the number of fourth light attenuation values in the at least one piece of third light attenuation value.
The fourth light attenuation value is a light attenuation value corresponding to the mutation point in the at least one third light attenuation value.
Illustratively, as shown in fig. 4, the correspondence between time of day and the light decay value is shown. Wherein, the light attenuation value corresponding to 8:30 and the light attenuation value corresponding to 9:10 are mutation points.
In one possible implementation manner, the server may perform variable point detection on at least one third light attenuation value in the third information through the loss function, and determine a mutation point in the at least one third light attenuation value.
It should be noted that, the loss function in the embodiment of the present application may be a loss function based on a rate of change of the loss function.
In one possible design, the server may determine a predicted light attenuation value corresponding to each first preset time in the first preset period based on the loss function, and calculate a difference between a third light attenuation value corresponding to each first preset time and the predicted light attenuation value, to generate at least one first difference value, where one first preset time corresponds to one first difference value. Then, the server may determine a second difference value of the target period based on each first difference value in the at least one first difference value, and determine a third difference value corresponding to each moment in the target period by a sliding window moving method, where the target period is a sum of the first difference values corresponding to the first preset moments in the target period and the second difference value of any one of the target periods in the first preset period.
It should be noted that, for the process of determining the third difference value corresponding to each time in the target period by the server through the method of moving the sliding window, reference may be made to the description of determining the difference value by moving the sliding window in the conventional technology, which is not repeated herein.
In one possible design, the third difference value corresponding to each time in the target period may be represented by equation two, equation three, equation four, and equation five.
D v＝c1(yt)-c2(yt)-c3(yt) equation five.
Wherein c 1(yt) is used for indicating the second difference value of the period (u, w), y ' t is used for indicating the third light attenuation value corresponding to the first preset time t, β 1 is used for indicating the variance coefficient of the period (u, w), ε 1 is used for indicating the regression coefficient of the period (u, w), y ' t-t*β1+ε1 is used for indicating the first difference value corresponding to the first preset time in the period (u, w), c 2(yt) is used for indicating the second difference value of the period (u, v), time v is any one of the first preset times in the period (u, w), β 2 is used for indicating the variance coefficient of the period (u, v), ε 2 is used for indicating the regression coefficient of the period (u, v), y ' t-t*β2+ε2 is used for indicating the first difference value corresponding to the first preset time t in the period (u, v), ε 3(yt is used for indicating the second difference value corresponding to the first preset time in the period (u, w), β 3 is used for indicating the variance coefficient of the period (v, 3) in the period (u, w), and ε 2 is used for indicating the variance coefficient of the first preset time t in the period (u, v) corresponding to the first difference value in the period (u, w).
In one possible design, the server may use a time when the corresponding third difference value in the target period is smaller than the preset difference threshold as the mutation point. And then, the server can take the third light attenuation value corresponding to the abrupt point as a fourth light attenuation value.
In one possible implementation manner, the server may determine the number of fourth light attenuation values in at least one third light attenuation value in each third information, so as to obtain the number of fourth light attenuation values corresponding to each third information.
S303, the server determines a first line from at least one second line according to the number of fourth light attenuation values corresponding to each piece of third information.
The first circuit is a second circuit corresponding to third information with the number of the fourth light attenuation values being larger than a first preset number threshold.
It can be understood that the server may determine the number of abrupt change points in the historical light attenuation value of each line, and screen out lines with the number of abrupt change points greater than the first preset number threshold according to the number of abrupt change points in the historical light attenuation value of each line. Therefore, the number of lines checked by the server can be reduced, and the efficiency of checking the lines by the server is improved.
In some embodiments, when the server acquires the first information, the server may use the third information corresponding to the first line as the first information.
In some embodiments, after the server obtains the first information, the server may divide at least one first light attenuation value according to a first preset time corresponding to each fourth light attenuation value, and generate at least one first set, where the first set may include first light attenuation values between two first preset times corresponding to two adjacent fourth light attenuation values.
Illustratively, the at least one first light decay value comprises a light decay value A, a light decay value B, a light decay value C, a light decay value D, a light decay value E, and a light decay value F. The first preset time corresponding to the light attenuation value A is 8 am, the first preset time corresponding to the light attenuation value B is 9 am, the first preset time corresponding to the light attenuation value C is 10 am, the first preset time corresponding to the light attenuation value D is 11 am, the first preset time corresponding to the light attenuation value E is 12 am, and the first preset time corresponding to the light attenuation value F is 1 pm. If the light attenuation value B, the light attenuation value D and the light attenuation value F are all fourth light attenuation values, the server generates a first set A and a first set B, wherein the first set A comprises a light attenuation value C, and the first set B comprises a light attenuation value E.
In a possible implementation manner, the server may further divide at least one first light attenuation value according to a first preset time corresponding to each fourth light attenuation value, an initial time of the first preset time period, and an end time of the first preset time period, so as to generate at least one first set, where the first set may further include a first light attenuation value between the initial time of the first preset time period and a first preset time corresponding to an adjacent fourth light attenuation value, and a first light attenuation value between the end time of the first preset time period and a first preset time corresponding to an adjacent fourth light attenuation value.
Illustratively, the at least one first light decay value comprises a light decay value A, a light decay value B, a light decay value C, a light decay value D, a light decay value E, and a light decay value F. The first preset time corresponding to the light attenuation value A is 8 am, the first preset time corresponding to the light attenuation value B is 9 am, the first preset time corresponding to the light attenuation value C is 10 am, the first preset time corresponding to the light attenuation value D is 11 am, the first preset time corresponding to the light attenuation value E is 12 am, and the first preset time corresponding to the light attenuation value F is 1 pm. If the light attenuation value B, the light attenuation value D and the light attenuation value F are all fourth light attenuation values, the server generates a first set A, a first set B, a first set C and a first set D, wherein the first set A comprises the light attenuation value A, the first set B comprises the light attenuation value B and the light attenuation value C, the first set C comprises the light attenuation value D and the light attenuation value E, and the first set D comprises the light attenuation value F.
Alternatively, the server may display at least one first set of at least one first light decay value in the form of an image.
Illustratively, in connection with the correspondence between the moments and the light decay values shown in fig. 4, a correspondence between the light decay values and the first set is shown in fig. 5. The set A, the set B and the set C are all first sets, the set A comprises a light attenuation value corresponding to 8:00, a light attenuation value corresponding to 8:10 and a light attenuation value corresponding to 8:20, the set B comprises a light attenuation value corresponding to 8:30, a light attenuation value corresponding to 8:40, a light attenuation value corresponding to 8:50 and a light attenuation value corresponding to 9:00, and the set C comprises a light attenuation value corresponding to 9:10, a light attenuation value corresponding to 9:20, a light attenuation value corresponding to 9:30, a light attenuation value corresponding to 9:40 and a light attenuation value corresponding to 9:50.
In an embodiment of the present application, in S203, the server may determine whether the second set exists in the at least one first set. Wherein the second set is a first set having a first light decay value greater than a first threshold.
It can be understood that the server may divide the historical light attenuation values of the line according to the abrupt points in the historical light attenuation values of the line, and check the divided light attenuation values. Therefore, the number of the light attenuation values checked by the server can be reduced, and the efficiency of checking the light attenuation values by the server is improved.
In some embodiments, if the server determines that there is a second set in the at least one first set, the server performs S204.
In some embodiments, after the server generates the at least one first set, the server may determine at least one fourth set from the at least one first set, the fourth set being a set of the at least one first set that includes a first preset time instant later than a fourth preset time instant. The server may then determine whether the second set is present in the at least one fourth set. If the server determines that the second set exists in the at least one fourth set, the server performs S204.
In one possible implementation manner, if the number of fourth sets in the at least one first set is smaller than the third preset number, the server may add a fifth set to the at least one fourth set to generate a sixth set of the third preset number, where the sixth set of the third preset number includes the fourth set and the fifth set. The server may then determine whether the second set is present in the third predetermined number of sixth sets. If the server determines that the second set exists in the third preset number of sixth sets, the server executes S204.
It can be understood that after the server divides the historical light attenuation values of the line, the server can screen the divided light attenuation values and check the divided and screened light attenuation values. Therefore, the number of the light attenuation values checked by the server can be reduced, and the efficiency of checking the light attenuation values by the server is improved.
In some embodiments, after S202, the server may process the first threshold value and the first preset threshold value to generate the second threshold value. The second threshold is the sum of the first threshold and a first preset threshold, and the second threshold is larger than the first threshold. The server may then determine whether there is a light decay value of the at least one first light decay value that is greater than a first threshold and less than a second threshold.
It is understood that the server may generate the second threshold according to the first threshold and the first preset threshold. The server may then determine whether there is a light decay value of the at least one first light decay value that is greater than a first threshold and less than a second threshold. Therefore, valuable references can be provided for the server to predict the state of the line, the reference quantity of the server to the state prediction of the line is increased, and the accuracy of the prediction result is improved.
In some embodiments, if the server determines that there is a light decay value greater than the first threshold and less than the second threshold in the at least one first light decay value, the server performs S204.
In other embodiments, the server generates the second predictive information if the server determines that there is a light decay value greater than a second threshold in the at least one first light decay value. The second prediction information is used for indicating that the first line has a degradation trend within a third preset period and has potential safety hazards.
In some embodiments, the number of first lines may be a plurality. The server may obtain first information and second information corresponding to each of the plurality of first lines. And then, the server can determine whether the light attenuation value which is larger than a first threshold value and smaller than a second threshold value exists in at least one first light attenuation value corresponding to each first line, classify the first lines and determine a first line, a second line and a third line. The first type of lines are first lines with first light attenuation values larger than a first threshold value and smaller than a second threshold value, the second type of lines are first lines with first light attenuation values larger than the second threshold value, and the third type of lines are first lines with first light attenuation values smaller than the first threshold value. Then, the server may generate first prediction information for the first type of line, second prediction information for the second type of line, and third prediction information for the third type of line.
It should be noted that, in the process of classifying the plurality of first lines by the server, the server may classify the plurality of first lines by using the multi-classifier with the extreme gradient lifting (eXtreme Gradient Boosting, XGBoost).
