Description

Technical Field

[0001] The present application relates to the technical field of optical cable monitoring, and in particular to an intelligent monitoring method and system for preventing an optical cable from being damaged by external forces. Background Art

[0002] Regarding the monitoring of optical cables damaged by external forces, it is necessary to obtain and analyze the stress change parameters of the optical cables, namely the strain parameters, through optical fiber sensors, and locate the position of the optical cables with abnormal strain parameters through optical fiber sensors, so as to quickly determine the position where the optical cables are damaged by external forces for timely maintenance.

[0003] However, due to the large number and complexity of optical fiber links, and the fact that the positioning function is greatly affected by the ambient temperature, single optical fiber sensing for monitoring is prone to inaccurate positioning of abnormal strain parameters, resulting in high time costs for subsequent maintenance, so improvements are needed. Summary of the invention

[0004] In order to improve the accuracy of locating abnormal positions of strain parameters in optical fiber links and reduce the occurrence of optical cables being damaged by irreversible external forces, the present application provides an intelligent monitoring method and system for preventing optical cables from being damaged by external forces.

[0005] The above-mentioned invention objective of the present application is achieved through the following technical solutions:

[0006] An intelligent monitoring method for preventing an optical cable from being damaged by external forces comprises the steps of:

[0007] When receiving strain abnormality data sent by the optical fiber sensing terminal, the strain abnormality data is sent to the pre-trained fault location model, where the strain abnormality data includes basic location information of the strain parameters given by the optical fiber sensing terminal;

[0008] When the fault location model receives the abnormal strain data, it identifies the optical cable line information corresponding to the abnormal strain data;

[0009] Based on the optical cable line information, determine whether to perform positioning deviation calculation;

[0010] When the positioning deviation calculation needs to be performed, based on the basic positioning information and the optical cable line information, the corresponding deviation calculation rule in the fault location model is retrieved, and the positioning deviation value is output;

[0011] Combine the basic positioning information with the positioning deviation value and output the target positioning information to the operation and maintenance terminal.

[0012] By adopting the above technical solution, since the strain parameters at the location damaged by external force in the optical cable line will be abnormal, that is, the strain abnormality data is collected, and the outdoor optical cable line is affected by the high temperature environment, the positioning of the strain abnormality data is inaccurate. Therefore, the temperature influence factor is taken into account by setting the fault location model, and the environment in which the optical cable line is located is obtained through the optical cable line information to determine whether it is necessary to perform positioning deviation calculation, and further through the preset deviation calculation rules, the position of the optical cable where the strain abnormality data appears is recalculated, thereby greatly eliminating the influence of the ambient temperature on the positioning of the optical cable damaged by external force. The operation and maintenance terminal receives the target positioning information more accurately, and improves the accuracy of positioning the abnormal position of the strain parameter in the optical fiber link, so as to reduce the situation where the optical cable is damaged by irreversible external force.

[0013] Optionally, when the fault location model receives the abnormal strain data, identifying the optical cable line information corresponding to the abnormal strain data includes:

[0014] When the fault location model receives the strain anomaly data, it extracts the corresponding optical cable model identifier from the strain anomaly data;

[0015] Acquire complete line information of the optical cable based on the optical cable model identifier, wherein the complete line information is composed of a plurality of optical cable segment information;

[0016] Based on the basic positioning information, all the optical cable segment information from the optical fiber sensing terminal to the location where the strain abnormality data appears is screened out as the optical cable line information.

[0017] By adopting the above technical solution, different optical cable lines correspond to different strain anomaly data, so it is necessary to obtain the optical cable model to identify the optical cable line. Furthermore, since the optical cable line is long and the environment in which the optical cable is located is relatively complex, in order to make the judgment and calculation of the positioning deviation more accurate, the complete optical cable line is divided into several optical cable segments, namely, the optical cable segmentation information.

[0018] Optionally, judging whether to perform positioning deviation calculation based on the optical cable line information includes:

[0019] Obtain the current optical cable temperature data of each optical cable segment information that is screened;

[0020] The fault location model retrieves the temperature threshold of the corresponding optical cable line information and compares it with the temperature data. Based on the comparison results of all optical cable segment information, it determines whether to perform the positioning deviation calculation.

[0021] By adopting the above technical solution, in order to determine whether to perform the positioning deviation calculation, it is necessary to obtain the temperature of each section of the optical cable line that has been distinguished, and compare it with the temperature threshold to obtain multiple groups of comparison results. This can improve the stability of the positioning deviation calculation and provide rich input data for subsequent deviation calculation rules, making the calculation of the positioning deviation value more accurate.

[0022] Optionally, judging whether to perform positioning deviation calculation based on the comparison result of all optical cable segment information includes:

[0023] Positioning deviation calculation is performed when any of the following comparison results are met:

[0024] When the temperature data of any one or more optical cable segment information is greater than the temperature threshold, and the temperature difference is greater than or equal to the preset extreme difference value;

[0025] and / or,

[0026] When the temperature data is greater than the temperature threshold, the quantity of the optical cable segmentation information is greater than or equal to a preset quantity value.

[0027] By adopting the above technical scheme, when there is a section of optical cable line in the optical cable segmentation information whose temperature data is greater than the temperature threshold and the temperature difference is greater than the extreme value, it proves that the temperature of the section of optical cable line is too high and reaches the default value, which seriously affects the optical cable position positioning where abnormal strain data appears. In this case, even if there is a section of optical cable segment information whose temperature data is greater than the temperature threshold, the positioning deviation value should be calculated. In another case, the number of optical cable segment information whose temperature data is greater than the temperature threshold is greater than the preset number value, which proves that most of the optical cable segments are in a relatively high temperature state, and therefore has a greater overall impact on the optical cable position positioning of the abnormal strain data, so it is also necessary to calculate the positioning deviation value.

[0028] Optionally, when the positioning deviation calculation needs to be performed, based on the basic positioning information and the optical cable line information, the corresponding deviation calculation rule in the fault location model is retrieved, and the positioning deviation value is output; including:

[0029] When it is necessary to perform positioning deviation calculation, all optical cable segment information whose temperature data is greater than the temperature threshold is obtained in the optical cable line information;

[0030] The fault location model retrieves a deviation calculation rule that matches the optical cable line information;

[0031] The temperature difference corresponding to each section of the optical cable segment information is input into the deviation calculation rule to calculate the positioning deviation value.

[0032] By adopting the above technical solution, the deviation calculation rule needs to be matched according to the optical cable line information, that is, it needs to be matched according to the optical cable model identification. The deviation calculation rule needs to calculate the optical cable segment information whose temperature data of each segment is greater than the temperature threshold. During the calculation, multiple temperature difference values ​​are combined with the corresponding optical cable segments, and the analysis of the temperature impact on the optical cable line information is more comprehensive and detailed, which helps to improve the accuracy of the positioning deviation value calculation.

[0033] Optionally, the step of inputting the temperature difference corresponding to each optical cable segment information into a deviation calculation rule to calculate the positioning deviation value includes:

[0034] Arrange the received temperature difference values ​​in sequence from the optical fiber sensing terminal to the location where the strain abnormality data appears, and obtain the distribution data of the temperature difference values;

[0035] The fault location model identifies a distribution pattern similar to the distribution data from a preset database, and obtains a deviation value matching the distribution pattern;

[0036] Then, based on the distribution pattern and distribution data, the deviation value is adjusted differentially and the final positioning deviation value is output.

[0037] By adopting the above technical solution, since the basic positioning information refers to the distance from the location where the optical cable has abnormal stress changes to the optical fiber sensing terminal, this distance is greatly affected by the ambient temperature of the optical cable along the line. The temperature difference is arranged in order from the optical fiber sensing terminal to the location where the strain abnormality data appears. The distribution of the temperature difference along the optical cable can be known. The fault location model further identifies the distribution data of the temperature difference from the preset database, and can find the temperature difference distribution form that is most similar to the current distribution data from the temperature difference distribution form of previous simulation experiments, and obtain the deviation value matching the distribution form. However, there will also be some deviations in the distribution trend. Therefore, the deviation value of the most similar distribution form is adjusted through differentiated adjustment, and finally the positioning deviation value corresponding to the current temperature difference distribution data is obtained.

[0038] Optionally, combining the basic positioning information with the positioning deviation value and outputting the target positioning information to the operation and maintenance terminal includes:

[0039] The positioning deviation value includes a positive positioning deviation value and a negative positioning deviation value, and the positioning deviation value is used to adjust the relative distance between the location of the strain anomaly data and the location of the optical fiber sensing terminal, wherein the adjustment of the positive positioning deviation value and the negative positioning deviation value represents the opposite displacement direction along the optical cable line, and is converted into longitude and latitude data to obtain target positioning information.

[0040] By adopting the above technical solution, the positive positioning deviation value and the negative positioning deviation value are used to adjust the distance from the optical fiber sensing terminal to the location where the strain abnormality data appears, and then converted into longitude and latitude data to output the target positioning information, which is convenient for adjusting the position of the optical cable where the strain abnormality data appears, and also convenient for the operation and maintenance terminal to find the corresponding stress fault point.

[0041] The second object of the invention is achieved by the following technical solutions:

[0042] An intelligent monitoring system for preventing an optical cable from being damaged by external forces, comprising:

[0043] A data receiving and sending module is used to send the strain abnormality data to a pre-trained fault location model when receiving the strain abnormality data sent by the optical fiber sensing terminal, wherein the strain abnormality data includes basic location information of the strain parameters given by the optical fiber sensing terminal;

[0044] A line identification module, used for identifying the optical cable line information corresponding to the strain abnormality data when the fault location model receives the strain abnormality data;

[0045] A judgment module, used to judge whether to perform positioning deviation calculation based on the optical cable line information;

[0046] The deviation calculation module is used to retrieve the corresponding deviation calculation rules in the fault location model based on the basic positioning information and the optical cable line information when the positioning deviation calculation needs to be performed, and output the positioning deviation value;

[0047] The output module is used to combine the basic positioning information with the positioning deviation value and output the target positioning information to the operation and maintenance terminal.

[0048] The third objective of the present application is achieved through the following technical solutions:

[0049] A computer device comprises a memory, a processor and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the above-mentioned intelligent monitoring method for preventing an optical cable from being damaged by external forces are implemented.

[0050] The fourth objective of the present application is achieved through the following technical solutions:

[0051] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned intelligent monitoring method for preventing an optical cable from being damaged by external forces are implemented.

[0052] In summary, the present application includes at least one of the following beneficial technical effects:

[0053] 1. The temperature influence factor is taken into account by setting up the fault location model, and the environment of the optical cable line is obtained through the optical cable line information to determine whether it needs to perform positioning deviation calculation. The preset deviation calculation rules are further used to recalculate the position of the optical cable with abnormal strain data, thereby greatly eliminating the influence of ambient temperature on the location of the optical cable damaged by external forces. The operation and maintenance terminal receives more accurate target positioning information, and improves the accuracy of locating the abnormal position of strain parameters in the optical fiber link, so as to reduce the situation where the optical cable is damaged by irreversible external forces;

[0054] 2. Different optical cable lines correspond to different strain anomaly data, so it is necessary to obtain the optical cable model to identify the optical cable line. Furthermore, since the distance of the optical cable line is long and the environment in which the optical cable is located is also more complex, in order to make the judgment and calculation of the positioning deviation more accurate, the complete optical cable line is divided into several optical cable segments, that is, the optical cable segmentation information;

[0055] 3. When the temperature data of a section of optical cable line in the optical cable segment information is greater than the temperature threshold and the temperature difference is greater than the extreme value, it proves that the temperature of the section of optical cable line is too high and reaches the default value that seriously affects the optical cable position positioning with abnormal strain data. Even if there is a section of optical cable segment information with temperature data greater than the temperature threshold, the positioning deviation value calculation should be performed;

[0056] 4. The fault location model identifies the distribution data of the temperature difference from the preset database, and can find the one that is most similar to the current distribution data from the temperature difference distribution forms of previous simulation experiments, and obtain the deviation value that matches the distribution form. However, there will also be some deviations in the distribution trend. Therefore, the deviation value of the most similar distribution form is adjusted through differentiated adjustment, and finally the positioning deviation value corresponding to the current temperature difference distribution data is obtained.

[0061] The following is combined with Figure 1-4This application is described in further detail.

[0062] In the following embodiments, Figure 1 As shown, the present application discloses an intelligent monitoring method for preventing an optical cable from being damaged by external forces, which specifically includes the following steps:

[0063] S10: When receiving strain abnormality data sent by the optical fiber sensing terminal, sending the strain abnormality data to a pre-trained fault location model, the strain abnormality data includes basic location information of strain parameters given by the optical fiber sensing terminal;

[0064] In this embodiment, the fiber optic sensing terminal is a fiber optic sensor. The strain anomaly data includes the strain parameters that change when the optical cable is damaged by external force and the distance data obtained by measuring the round-trip time of the pulse light through the fiber optic sensor, and the basic positioning information is obtained by positioning conversion based on the distance data. The basic positioning information currently obtained does not take into account the situation where the optical cable is affected by the ambient temperature.

[0065] The fault location model is a model trained by a neural network and used to determine whether the position of the optical cable with abnormal strain data needs to be adjusted and to perform positioning adjustment.

[0066] S20: When the fault location model receives the abnormal strain data, it identifies the optical cable line information corresponding to the abnormal strain data;

[0067] In this embodiment, the optical cable line information includes an identifier for identifying a specific optical cable line. Optical cables of different materials and specifications will have inconsistent judgment parameters for the fault location model.

[0068] Specifically, refer to Figure 2 , step S20 comprises the steps of:

[0069] S21: When the fault location model receives the strain abnormality data, it extracts the corresponding optical cable model identifier from the strain abnormality data;

[0070] S22: acquiring complete line information of the optical cable based on the optical cable model identifier, wherein the complete line information is composed of a plurality of optical cable segment information;

[0071] S23: Based on the basic positioning information, all optical cable segment information from the optical fiber sensing terminal to the location where the strain abnormality data appears is screened out as the optical cable line information.

[0072] In this embodiment, the optical cable model identification is used to identify the optical cable line of specific material and specification, the complete line information is the complete optical cable line, and the multiple optical cable segment information represents that the complete optical cable line is customized to be divided into multiple optical cable segments, which are usually distinguished according to length or environmental terrain.

[0073] Among them, all the optical cable segment information from the optical fiber sensing terminal to the location where the abnormal strain data appears is screened out, including the complete optical cable segment information where the abnormal strain data appears is screened out.

[0074] S30: Based on the optical cable line information, determine whether to perform positioning deviation calculation;

[0075] In this embodiment, the optical cable line information refers to all optical cable segment information from the optical fiber sensing terminal to the location where the strain abnormality data appears. The positioning deviation calculation is used to adjust the distance between the location where the strain abnormality data is located and the location where the optical fiber sensing terminal is located.

[0076] Specifically, step S30 includes the following steps:

[0077] The step of determining whether to perform positioning deviation calculation based on the optical cable line information includes:

[0078] S31: obtaining the current optical cable temperature data of each selected optical cable segment information;

[0079] S32: The fault location model retrieves the temperature threshold of the corresponding optical cable line information, compares it with the temperature data, and determines whether to perform the location deviation calculation based on the comparison result of all the optical cable segment information.

[0080] In this embodiment, by installing a temperature sensor on the surface of each section of optical cable and a small processor connected to the signal network, the temperature data corresponding to each optical cable segment information can be obtained. In other embodiments, for long-distance optical cable lines, the temperature of the geographical location of the optical cable segment can be obtained for judgment.

[0081] The temperature threshold is custom set after multiple simulation experiments. If the temperature data is greater than the temperature threshold, it means that the current temperature data will affect the accuracy of the basic positioning information.

[0082] Based on the comparison results of all the optical cable segment information, it is judged whether to perform the positioning deviation calculation. Among them, the positioning deviation calculation is performed when any of the following and the comparison results are met:

[0083] When the temperature data of any or more optical cable segment information is greater than the temperature threshold, and the temperature difference is greater than or equal to the preset extreme value, the extreme value is customized based on multiple simulation experiments;

[0084] and / or,

[0085] When the temperature data is greater than the temperature threshold, the number of optical cable segment information is greater than or equal to a preset number value, and the number of segment information is custom set by multiple simulation experiments, and is usually set to 2 segments.

[0086] When the number of optical cable segment information whose temperature data is greater than the temperature threshold is less than a preset number value, and the temperature difference between the temperature data and the temperature threshold is less than the extreme value, it is determined that there is no need to perform positioning deviation calculation.

[0087] S40: When it is necessary to perform positioning deviation calculation, based on the basic positioning information and the optical cable line information, the corresponding deviation calculation rule in the fault positioning model is retrieved, and the positioning deviation value is output;

[0088] In this embodiment, the fault location model needs to obtain the model identification of the optical cable from the optical cable line information, and learn the material and specifications of the optical cable line to determine the impact of the ambient temperature on the positioning of the optical cable line, so as to retrieve the corresponding deviation calculation rules. The deviation calculation rules are used to filter out the approximate distribution state from the database according to the distribution of the temperature difference of each optical cable segment information, so as to output the positioning deviation value according to the deviation adjustment recommendation plan stored in the simulation experiment.

[0089] Specifically, refer to Figure 3 , step S40 comprises the steps of:

[0090] S41: when it is necessary to perform positioning deviation calculation, obtain all optical cable segment information whose temperature data is greater than a temperature threshold in the optical cable line information;

[0091] S42: The fault location model retrieves a deviation calculation rule that matches the optical cable line information;

[0092] S43: Input the temperature difference corresponding to each section of the optical cable segment information into the deviation calculation rule to calculate the positioning deviation value.

[0093] In this embodiment, the optical cable segment information whose temperature data is less than or equal to the temperature threshold is not subjected to deviation calculation.

[0094] After receiving the temperature difference values ​​corresponding to the segment information of several optical cables, the deviation calculation rule arranges the received temperature difference values ​​in sequence from the optical fiber sensing terminal to the location where the strain abnormality data appears, and obtains the distribution data of the temperature difference values;

[0095] The fault location model identifies a distribution form similar to the distribution data from a preset database and obtains a deviation value matching the distribution form; the preset database stores various temperature difference distribution forms obtained through multiple simulation experiments in the past. For a distribution form similar to the distribution data, the order of the temperature difference and the change of the previous and next values ​​must be considered.

[0096] Based on the distribution form and distribution data, the deviation value is adjusted differentially and the final positioning deviation value is output. The differential adjustment is based on the size of the temperature difference between adjacent ones and the magnitude of the change in the temperature difference before and after. For example, if the temperature difference before and after in the distribution data does not change much and is larger than the temperature difference in the pre-stored distribution form, the deviation value is increased. The obtained positioning deviation value is larger than the deviation value of the pre-stored distribution form.

[0097] S50: Combine the basic positioning information with the positioning deviation value, and output the target positioning information to the operation and maintenance terminal.

[0098] In this embodiment, the positioning deviation value includes a positive positioning deviation value and a negative positioning deviation value, and the positioning deviation value is used to adjust the relative distance between the location of the strain anomaly data and the location of the optical fiber sensing terminal, wherein the adjustment of the positive positioning deviation value and the negative positioning deviation value represents the opposite direction of the displacement along the optical cable line, and is converted into longitude and latitude data to obtain target positioning information.

[0099] The operation and maintenance terminal refers to a PC or mobile terminal used by optical cable operation and maintenance personnel.

[0100] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
