Description

Technical Field

[0001] This invention belongs to the field of optical cable data analysis technology, specifically a resource visualization method, device, and system based on pipeline optical cable management. Background Technology

[0002] With the rapid development of optical fiber communication technology, optical cables, as the core carrier of information transmission, are directly affected by their laying method, which affects the stability, reliability and operation and maintenance costs of communication networks. As one of the mainstream laying methods, duct optical cables refer to optical cables that are laid in pre-laid underground ducts. They are widely used in urban backbone networks, metropolitan area networks, access networks and interconnection of industrial parks and data centers, and are a key component supporting digital economy infrastructure such as 5G communication, industrial Internet and smart cities.

[0003] In the existing technology, the maintenance of duct optical cables mostly adopts the regular maintenance mode. However, due to the different laying depths of underground duct optical cables, different duct optical cables will have different sensitivities to vibration. The duct optical cables with shallow laying depth are more sensitive to vibration, while the duct optical cables with deep laying depth are less sensitive to vibration. For duct optical cables with high vibration sensitivity, a more refined maintenance mode is required. Existing methods cannot achieve the visualization and adjustment of duct optical cable maintenance resources based on the strength of vibration sensitivity.

[0004] To this end, the present invention proposes a resource visualization method, device and system based on pipeline optical cable management. Summary of the Invention

[0005] The purpose of this invention is to propose a resource visualization method, device, and system based on pipeline optical cable management, so as to solve the problem mentioned in the background art that it is impossible to visualize and adjust pipeline optical cable maintenance resources based on vibration sensitivity.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] The first aspect is a resource visualization method based on pipeline optical cable management, which includes the following steps:

[0008] Step S1: Calculate the theoretical attenuation of the optical signal inside the optical cable in the duct based on the length and bending radius;

[0009] Step S2: Analyze whether the duct optical cable is a vibration-sensitive optical cable based on the changing trend of the attenuation deviation value and the vibration amplitude.

[0010] Step S3: Divide the analysis period into different maintenance intervals based on different maintenance times, and calculate the reference vibration data of the vibration-sensitive optical cable.

[0011] Step S4: Construct a maintenance judgment interval and calculate the actual vibration data of the vibration-sensitive optical cable within the maintenance judgment interval;

[0012] Step S5: Determine whether vibration-sensitive optical cables need to be maintained in advance based on reference vibration data and actual vibration data.

[0013] Furthermore, the calculation process in step S1 includes the following sub-steps:

[0014] Step S101: Measure the length of the optical cable in the duct and calculate the distance attenuation of the optical signal inside the optical cable.

[0015] Step S102: Collect the bending radius of the optical cable in the duct and calculate the bending attenuation of the optical signal inside the optical cable.

[0016] Step S103: Summing the distance attenuation and bending attenuation yields the theoretical attenuation of the optical signal inside the duct optical cable.

[0017] Furthermore, the analysis process in step S2 includes the following sub-steps:

[0018] Step S21: Take any past time point as the starting node and another past time point as the ending node, and construct the analysis time period with the starting node as the left endpoint and the ending node as the right endpoint.

[0019] Step S22: Obtain the initial power of the optical signal at the input end of the optical cable and the actual power at the receiving end at different time points, and compare the initial power and actual power of the optical signal at different time points;

[0020] If the initial power of the optical signal is less than the actual power at all time points, an early warning will be issued immediately.

[0021] If the initial power of the optical signal is greater than or equal to the actual power at any time point, the actual attenuation of the optical cable in the pipeline at the corresponding time point can be calculated.

[0022] Step S23: Subtract the theoretical attenuation from the actual attenuation and take the absolute value to obtain the attenuation deviation value of the optical signal in the optical cable at different time points. Construct a first coordinate system with the time point as the horizontal axis and the attenuation deviation value as the vertical axis, and plot the attenuation deviation point in the first coordinate system according to the attenuation deviation value corresponding to different time points.

[0023] Step S24: Vibration data of the duct optical cable is collected at fixed time intervals, and a second coordinate system is constructed with time nodes as the horizontal axis and vibration amplitude as the vertical axis. At the same time, the amplitude points are plotted in the second coordinate system according to the vibration amplitude corresponding to different time nodes. The vibration data includes the vibration amplitude and vibration frequency of the duct optical cable.

[0024] Step S25: Connect adjacent attenuation deviation points in the first coordinate system in sequence to obtain the attenuation broken line of the duct optical cable, and connect adjacent amplitude points in the second coordinate system in sequence to obtain the amplitude broken line of the duct optical cable.

[0025] Step S26: Perform a joint analysis of the attenuation curve and amplitude curve of the optical cable in the pipeline.

[0026] Furthermore, the analysis process in step S26 includes the following sub-steps:

[0027] Step S261: Obtain the coordinates of different attenuation deviation points and record them as attenuation deviation point coordinates; obtain the coordinates of different amplitude points and record them as amplitude point coordinates; calculate the slopes of the attenuation broken line and the amplitude broken line.

[0028] Step S262: Record the attenuation line or amplitude line with a slope greater than or equal to zero as a positive slope line, and record the attenuation line or amplitude line with a slope less than zero as a negative slope line.

[0029] Step S263: Construct the first sub-time period with the first time node in the analysis time period as the left endpoint and the adjacent time node as the right endpoint; construct the second sub-time period with the second time node as the left endpoint and the third time node as the right endpoint; construct the (i-1)th sub-time period with the (i-1)th time node as the left endpoint and the ith time node as the right endpoint.

[0030] Step S264: If both the decay line and the amplitude line in the first sub-time period are positive slope lines or negative slope lines, then the corresponding time period is recorded as the cooperative change time period.

[0031] If the decay line in the first sub-time period is a positive slope line, but the amplitude line is a negative slope line, then the corresponding time period is recorded as a non-coordinated change time period.

[0032] If the decay line in the first sub-time period is a negative slope line, but the amplitude line is a positive slope line, then the corresponding time period is recorded as a non-coordinated change time period.

[0033] Step S265: Count the number of time periods with coordinated changes and record them as the number of coordinated changes; count the number of time periods with non-coordinated changes and record them as the number of non-coordinated changes; record the optical cables in the pipeline with a number of coordinated changes greater than the number of non-coordinated changes as vibration-sensitive optical cables; and record the optical cables in the pipeline with a number of coordinated changes less than or equal to the number of non-coordinated changes as non-vibration-sensitive optical cables.

[0034] Further, step S3 includes the following sub-steps:

[0035] Step S31: Obtain the historical maintenance time of the vibration-sensitive optical cable within the analysis period, and sort the historical maintenance time in ascending order according to time. Record the historical maintenance time as the first maintenance time, the second maintenance time, ..., the kth maintenance time, where k = 1, 2, ..., j, and k is the number of the maintenance time.

[0036] Step S32: Divide the analysis period into multiple maintenance interval time periods according to different maintenance times, and denot them as the first maintenance interval time period, the second maintenance interval time period, ..., the mth maintenance interval time period, where m = 1, 2, ..., k-1, and m is the number of the maintenance interval time period.

[0037] Step S33: Select the first maintenance interval time period as the analysis object, and obtain the vibration data of the vibration-sensitive optical cable at different time nodes. Subtract the first maintenance time from the second maintenance time to obtain the first interval duration of the first maintenance interval time period.

[0038] Similarly, the interval lengths of the second maintenance interval time period and the mth maintenance interval time period are calculated and recorded as the second interval length and the mth interval length, respectively.

[0039] Step S34: Sum the vibration frequencies at different time points within the first maintenance interval and multiply them by the first interval duration to obtain the historical vibration count of the vibration-sensitive optical cable within the first maintenance interval.

[0040] Similarly, the historical vibration count of the vibration-sensitive optical cable within different maintenance intervals was calculated.

[0041] Step S35: Sum the vibration amplitudes at different time points within the first maintenance interval to obtain the historical vibration amplitude of the vibration-sensitive optical cable within the first maintenance interval.

[0042] Similarly, the historical vibration amplitude of the vibration-sensitive optical cable during different maintenance intervals was calculated.

[0043] Step S36: Iterate through and compare the historical vibration counts of the vibration-sensitive optical cable within different maintenance intervals to obtain the minimum historical vibration count, and record the minimum historical vibration count as the reference vibration count of the vibration-sensitive optical cable.

[0044] Step S37: Iterate through and compare the historical vibration amplitudes of the vibration-sensitive optical cable during different maintenance intervals to obtain the minimum historical vibration amplitude, and record the minimum historical vibration amplitude as the reference vibration amplitude of the vibration-sensitive optical cable.

[0045] Step S38: Record the reference vibration number and reference vibration amplitude as the reference vibration data of the vibration-sensitive optical cable.

[0046] Further, step S4 includes the following sub-steps:

[0047] Step S41: Select the kth maintenance time of the vibration-sensitive optical cable as the left endpoint and the current time node as the right endpoint to construct a maintenance judgment interval. Subtract the kth maintenance time from the time corresponding to the current time node to obtain the maintenance judgment duration of the maintenance judgment interval.

[0048] Step S42: Obtain the vibration frequency and vibration amplitude of the vibration-sensitive optical cable at different time points within the maintenance judgment interval, and multiply the sum of the vibration frequencies at different time points by the maintenance judgment duration to obtain the actual number of vibrations of the vibration-sensitive optical cable within the maintenance judgment interval.

[0049] Step S43: Sum the vibration amplitudes at different time points to obtain the actual vibration amplitude of the vibration-sensitive optical cable within the maintenance judgment interval;

[0050] Step S44: Record the actual number of vibrations and the actual vibration amplitude as the actual vibration data of the vibration-sensitive optical cable.

[0051] Furthermore, the judgment process in step S5 includes the following sub-steps:

[0052] Step S51: Obtain the interval duration corresponding to different maintenance interval time periods, and sum the first interval duration, the second interval duration, ..., the mth interval duration to obtain the average maintenance interval duration of the vibration-sensitive optical cable.

[0053] Step S52: Obtain the maintenance interval duration of the vibration-sensitive optical cable and compare the maintenance interval duration with the average repair interval duration;

[0054] If the maintenance interval of the vibration-sensitive optical cable is less than or equal to the average maintenance interval, no operation will be performed.

[0055] If the maintenance interval of the vibration-sensitive optical cable is longer than the average maintenance interval, proceed to step S53.

[0056] Step S53: Compare the actual number of vibrations of the vibration-sensitive optical cable within the maintenance judgment interval with the reference number of vibrations, and compare the actual vibration amplitude with the reference vibration amplitude.

[0057] If the actual number of vibrations of the vibration-sensitive optical cable is greater than or equal to the reference number of vibrations, or the actual vibration amplitude is greater than or equal to the reference vibration amplitude, the vibration-sensitive optical cable shall be maintained immediately.

[0058] If the actual number of vibrations of the vibration-sensitive optical cable is less than the reference number of vibrations, and the actual vibration amplitude is less than the reference vibration amplitude, then the vibration-sensitive optical cable will be continuously monitored.

[0059] Secondly, a resource visualization device based on pipeline optical cable management includes a database, an attenuation prediction module, an optical cable analysis module, a data analysis module, a data acquisition module, a vibration analysis module, and a maintenance judgment module.

[0060] The attenuation prediction module is used to analyze the attenuation of the optical signal in the duct optical cable, obtain the theoretical attenuation of the optical signal in the duct optical cable and send it to the optical cable analysis module; the optical cable analysis module is used to analyze the trend of attenuation deviation value and vibration amplitude to determine whether the duct optical cable is a vibration-sensitive optical cable, and send the maintenance time of the vibration-sensitive optical cable to the data analysis module.

[0061] The data analysis module is used to acquire different maintenance times in the database and divide the analysis time period into different maintenance interval time periods, calculate the reference vibration data of the vibration-sensitive optical cable and send it to the maintenance judgment module; the data acquisition module is used to acquire the real-time vibration data of the vibration-sensitive optical cable and send it to the vibration analysis module; the vibration analysis module is used to construct the maintenance judgment interval, calculate the actual vibration data of the vibration-sensitive optical cable within the maintenance judgment interval and send it to the maintenance judgment module; the maintenance judgment module is used to determine whether the vibration-sensitive optical cable needs to be maintained in advance based on the reference vibration data and the actual vibration data.

[0074] Figure 5 This is a schematic diagram of the resource visualization system in this invention. Detailed Implementation

[0075] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] Example 1: Please refer to Figures 1-3 As shown, the technical solution provided by this invention is: a resource visualization method based on duct optical cable management. This method first calculates the theoretical and actual attenuation of the optical signal within the duct optical cable. Then, based on the attenuation deviation and vibration amplitude, it determines whether the duct optical cable is a vibration-sensitive cable. Next, it calculates the reference vibration data and actual vibration data of the vibration-sensitive cable. Finally, it determines whether the vibration-sensitive cable needs advance maintenance, thereby achieving visualized maintenance of the duct optical cable. The specific method is as follows:

[0077] Step S1: Calculate the theoretical attenuation of the optical signal inside the optical cable in the duct based on the length and bending radius;

[0078] In this embodiment, the calculation process in step S1 includes the following sub-steps:

[0079] Step S101: Measure the length L of the optical cable in the duct, and calculate the distance attenuation JSJ of the optical signal in the duct using the formula JSJ=L×LSJ, where LSJ is the unit distance attenuation of the optical signal in the duct.

[0080] In this embodiment, the attenuation per unit distance can be obtained from the production specifications and technical data of the duct optical cable;

[0081] Step S102: Collect the bending radius BJ of the optical cable in the duct, and calculate the bending attenuation WSJ of the optical signal in the optical cable using the formula WSJ=RSJ×L / (BJ×BJ), where RSJ is the bending attenuation coefficient of the optical signal in the optical cable.

[0082] It should be explained that during the installation of duct optical cables, the installation environment will cause the duct optical cables to bend. The bending radius can be obtained by the installers during the installation or maintenance period of the duct optical cables. The bending attenuation coefficient can be obtained from the production specifications and technical data of the duct optical cables.

[0083] Step S103: Summing the distance attenuation and bending attenuation yields the theoretical attenuation of the optical signal within the duct optical cable. In this embodiment, the unit of unit distance attenuation is dB / m, the unit of length is m, therefore the unit of distance attenuation is dB. The unit of bending attenuation coefficient is dB×m, the unit of bending radius is m, therefore the unit of bending attenuation is also dB.

[0084] Step S2: Analyze whether the duct optical cable is a vibration-sensitive optical cable based on the changing trend of the attenuation deviation value and the vibration amplitude.

[0085] In this embodiment, the analysis process in step S2 includes the following sub-steps:

[0086] Step S21: Take any past time point as the starting node and another past time point as the ending node, and construct the analysis time period with the starting node as the left endpoint and the ending node as the right endpoint.

[0087] It should be noted that when selecting a time node, the starting node must be located before the ending node;

[0088] Step S22: Obtain the initial power PCS of the optical signal at the corresponding input end of the optical cable at different time points. i With the actual power PSJ at the receiving end i And compare the initial power of the optical signal with the actual power at different time points;

[0089] If the initial power of the optical signal is less than the actual power at all time points, an early warning will be issued immediately.

[0090] If at any time point the initial power of the optical signal is greater than or equal to the actual power, then by formula SJ i =10×lg(PCS i / PSJ i The actual attenuation SJ of the optical cable in the pipeline at the corresponding time node was calculated. i , where i = 1, 2, ..., n, i is the time node number, and lg is the logarithm to the base 10;

[0091] In this embodiment, the optical cable in the pipeline has an input end and a receiving end. The input end is used to transmit optical signals, and the receiving end is used to receive optical signals. Different time nodes are time nodes within the analysis period.

[0092] Step S23: Subtract the theoretical attenuation from the actual attenuation and take the absolute value to obtain the attenuation deviation value of the optical signal in the optical cable at different time points. Construct a first coordinate system with the time point as the horizontal axis and the attenuation deviation value as the vertical axis, and plot the attenuation deviation point in the first coordinate system according to the attenuation deviation value corresponding to different time points.

[0093] Step S24: Vibration data of the duct optical cable is collected at fixed time intervals, and a second coordinate system is constructed with time nodes as the horizontal axis and vibration amplitude as the vertical axis. At the same time, the amplitude points are plotted in the second coordinate system according to the vibration amplitude corresponding to different time nodes. The vibration data includes the vibration amplitude and vibration frequency of the duct optical cable.

[0094] In the specific implementation process, vibration sensors can be installed inside the optical cable in the pipeline to collect vibration data of the optical cable. It should be explained that the horizontal axis of the attenuation point represents time, and the vertical axis represents the attenuation deviation value at the corresponding time node. The horizontal axis of the amplitude point represents time, and the vertical axis represents the vibration amplitude at the corresponding time node.

[0095] Step S25: Connect adjacent attenuation deviation points in the first coordinate system in sequence to obtain the attenuation broken line of the duct optical cable, and connect adjacent amplitude points in the second coordinate system in sequence to obtain the amplitude broken line of the duct optical cable.

[0096] It should be noted that the horizontal axis in the first coordinate system and the second coordinate system is the same, both representing time, and the coordinate intervals of the horizontal axis are also the same;

[0097] Step S26: Perform a joint analysis of the attenuation and amplitude broken lines of the optical cable in the pipeline;

[0098] In this embodiment, the analysis process in step S26 includes the following sub-steps:

[0099] Step S261: Obtain the coordinates of different attenuation deviation points and record them as attenuation deviation point coordinates (T). i Si ), obtain the coordinates of different amplitude points and record them as amplitude point coordinates (T) i Z i ), through the formula XL1=(S i -S i-1 ) / (T i -T i-1 The slope XL1 of the attenuation piecewise linear curve is calculated using the formula XL2 = (Z i -Z i-1 ) / (T i -T i-1 The slope XL2 of the amplitude broken line was calculated.

[0100] Step S262: Record the attenuation line or amplitude line with a slope greater than or equal to zero as a positive slope line, and record the attenuation line or amplitude line with a slope less than zero as a negative slope line.

[0101] Step S263: Construct the first sub-time period with the first time node in the analysis time period as the left endpoint and the adjacent time node as the right endpoint; similarly, construct the second sub-time period with the second time node as the left endpoint and the third time node as the right endpoint, and construct the (i-1)th sub-time period with the (i-1)th time node as the left endpoint and the ith time node as the right endpoint.

[0102] For step S264, please refer to [link / reference]. Figure 2 As shown, if both the decay line and the amplitude line in the first sub-time period are positive slope lines or negative slope lines, then the corresponding time period is recorded as the cooperative change time period.

[0103] If the decay line in the first sub-time period is a positive slope line, but the amplitude line is a negative slope line, then the corresponding time period is recorded as a non-coordinated change time period.

[0104] If the decay line in the first sub-time period is a negative slope line, but the amplitude line is a positive slope line, then the corresponding time period is recorded as a non-coordinated change time period.

[0105] Step S265: Count the number of time periods with coordinated changes and record them as the number of coordinated changes; count the number of time periods with non-coordinated changes and record them as the number of non-coordinated changes; record the optical cables in the pipeline with a number of coordinated changes greater than the number of non-coordinated changes as vibration-sensitive optical cables; and record the optical cables in the pipeline with a number of coordinated changes less than or equal to the number of non-coordinated changes as non-vibration-sensitive optical cables.

[0106] In this embodiment, when the amplitude and attenuation deviation values ​​increase or decrease simultaneously, the corresponding pipeline optical cable is defined as a vibration-sensitive optical cable. In this scheme, only vibration-sensitive optical cables are analyzed.

[0107] Step S3: Divide the analysis period into different maintenance intervals based on different maintenance times, and calculate the reference vibration data of the vibration-sensitive optical cable.

[0108] In this embodiment, step S3 includes the following sub-steps:

[0109] Step S31, please refer to Figure 3 As shown, the historical maintenance times of vibration-sensitive optical cables within the analysis period are obtained, and the historical maintenance times are sorted in ascending order according to time. The historical maintenance times are recorded as the first maintenance time, the second maintenance time, ..., the kth maintenance time, where k = 1, 2, ..., j, and k is the number of the maintenance time.

[0110] Step S32: Divide the analysis period into multiple maintenance interval time periods according to different maintenance times, and denot them as the first maintenance interval time period, the second maintenance interval time period, ..., the mth maintenance interval time period, where m = 1, 2, ..., k-1, and m is the number of the maintenance interval time period.

[0111] It should be explained that there are a total of k maintenance times, therefore there are k-1 maintenance interval time periods, so the upper limit of m is k-1;

[0112] Step S33: Select the first maintenance interval time period as the analysis object, and obtain the vibration data of the vibration-sensitive optical cable at different time nodes. Subtract the first maintenance time from the second maintenance time to obtain the first interval duration of the first maintenance interval time period.

[0113] Similarly, the interval lengths of the second maintenance interval time period and the mth maintenance interval time period are calculated and recorded as the second interval length and the mth interval length, respectively.

[0114] Step S34: Sum the vibration frequencies at different time points within the first maintenance interval and multiply them by the first interval duration to obtain the historical vibration count of the vibration-sensitive optical cable within the first maintenance interval.

[0115] Similarly, the historical vibration count of the vibration-sensitive optical cable within different maintenance intervals was calculated.

[0116] Step S35: Sum the vibration amplitudes at different time points within the first maintenance interval to obtain the historical vibration amplitude of the vibration-sensitive optical cable within the first maintenance interval.

[0117] Similarly, the historical vibration amplitude of the vibration-sensitive optical cable during different maintenance intervals was calculated.

[0118] Step S36: Iterate through and compare the historical vibration counts of the vibration-sensitive optical cable within different maintenance intervals to obtain the minimum historical vibration count, and record the minimum historical vibration count as the reference vibration count of the vibration-sensitive optical cable.

[0119] Step S37: Iterate through and compare the historical vibration amplitudes of the vibration-sensitive optical cable during different maintenance intervals to obtain the minimum historical vibration amplitude, and record the minimum historical vibration amplitude as the reference vibration amplitude of the vibration-sensitive optical cable.

[0120] Step S38: Record the reference vibration number and reference vibration amplitude as the reference vibration data of the vibration-sensitive optical cable.

[0121] Step S4: Construct a maintenance judgment interval and calculate the actual vibration data of the vibration-sensitive optical cable within the maintenance judgment interval;

[0122] In this embodiment, step S4 includes the following sub-steps:

[0123] Step S41: Select the kth maintenance time of the vibration-sensitive optical cable as the left endpoint and the current time node as the right endpoint to construct a maintenance judgment interval. Subtract the kth maintenance time from the time corresponding to the current time node to obtain the maintenance judgment duration of the maintenance judgment interval.

[0124] It should be explained that the k-th maintenance time is selected here as the left endpoint of the maintenance judgment interval, with the maintenance time closest to the current time being used as the reference time. The maintenance judgment duration represents the duration between the current time node and the nearest maintenance time.

[0125] Step S42: Obtain the vibration frequency and vibration amplitude of the vibration-sensitive optical cable at different time points within the maintenance judgment interval, and multiply the sum of the vibration frequencies at different time points by the maintenance judgment duration to obtain the actual number of vibrations of the vibration-sensitive optical cable within the maintenance judgment interval.

[0126] Step S43: Sum the vibration amplitudes at different time points to obtain the actual vibration amplitude of the vibration-sensitive optical cable within the maintenance judgment interval;

[0127] Step S44: Record the actual number of vibrations and the actual vibration amplitude as the actual vibration data of the vibration-sensitive optical cable.

[0128] Step S5: Determine whether vibration-sensitive optical cables need to be maintained in advance based on reference vibration data and actual vibration data;

[0129] In this embodiment, the judgment process in step S5 includes the following sub-steps:

[0130] Step S51: Obtain the interval duration corresponding to different maintenance interval time periods, and sum the first interval duration, the second interval duration, ..., the mth interval duration to obtain the average maintenance interval duration of the vibration-sensitive optical cable.

[0131] Step S52: Obtain the maintenance interval duration of the vibration-sensitive optical cable and compare the maintenance interval duration with the average repair interval duration;

[0132] If the maintenance interval of the vibration-sensitive optical cable is less than or equal to the average maintenance interval, no operation will be performed.

[0133] If the maintenance interval of the vibration-sensitive optical cable is longer than the average maintenance interval, proceed to step S53.

[0134] It should be explained that when the maintenance interval of the vibration-sensitive optical cable is less than or equal to the average maintenance interval, it means that the abnormality of the vibration-sensitive optical cable occurred after maintenance, rather than due to a long period of non-maintenance. When the maintenance interval of the vibration-sensitive optical cable is longer than the average maintenance interval, it means that the abnormality of the vibration-sensitive optical cable is caused by a long period of non-maintenance.

[0135] Step S53: Compare the actual number of vibrations of the vibration-sensitive optical cable within the maintenance judgment interval with the reference number of vibrations, and compare the actual vibration amplitude with the reference vibration amplitude.

[0136] If the actual number of vibrations of the vibration-sensitive optical cable is greater than or equal to the reference number of vibrations, or the actual vibration amplitude is greater than or equal to the reference vibration amplitude, the vibration-sensitive optical cable shall be maintained immediately.

[0137] In practice, when the actual number of vibrations of a vibration-sensitive optical cable is greater than or equal to the reference number of vibrations, or the actual vibration amplitude is greater than or equal to the reference vibration amplitude, the optical cable number of the corresponding vibration-sensitive optical cable is obtained and the corresponding vibration-sensitive optical cable is marked as an optical cable to be maintained. At the same time, the optical cable number of the corresponding optical cable to be maintained is sent to the visualization screen of the operation and maintenance center. The operation and maintenance center can view the optical cable location and length of different optical cables to be maintained on the visualization screen according to the optical cable number, and assign operation and maintenance personnel to maintain the optical cables to be maintained according to the optical cable location, and provide real-time feedback on the maintenance progress of the operation and maintenance personnel to the visualization screen of the operation and maintenance center.

[0138] If the actual number of vibrations of the vibration-sensitive optical cable is less than the reference number of vibrations, and the actual vibration amplitude is less than the reference vibration amplitude, then the vibration-sensitive optical cable will be continuously monitored.
