Description

TECHNICAL FIELD

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

[0002] For monitoring of damage of optical cables by external force, stress change parameters, i.e. strain parameters, of the optical cables need to be acquired and analyzed by optical fiber sensors, and the positions of the optical cables with abnormal strain parameters are located by the optical fiber sensors, so as to quickly determine the positions of the optical cables damaged by external force for timely maintenance.

[0003] However, due to the large number of optical fiber links and the complex positioning function, the positioning of the positions with abnormal strain parameters is not accurate, which leads to high time cost of maintenance in the later stage, and thus needs to be improved. SUMMARY

[0004] In order to improve the accuracy of positioning of the positions with abnormal strain parameters in the optical fiber link and reduce the damage of the optical cables by irreversible external force, the application provides an intelligent monitoring method and system for preventing optical cables from being damaged by external force.

[0005] The above-mentioned application purpose of the application is achieved by the following technical scheme:

[0006] An intelligent monitoring method for preventing optical cables from being damaged by external force comprises the following steps:

[0007] When receiving strain abnormal data sent by an optical fiber sensing terminal, the strain abnormal data is sent to a pre-trained fault positioning model, and the strain abnormal data includes basic positioning information of strain parameters given by the optical fiber sensing terminal;

[0008] When the fault positioning model receives the strain abnormal data, the optical cable line information corresponding to the strain abnormal data is identified;

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

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

[0011] The basic positioning information and the positioning deviation value are combined, and target positioning information is outputted to an operation and maintenance terminal.

[0012] By adopting the technical scheme, since the strain parameters at the positions damaged by external force in the optical cable line are abnormal, that is, abnormal strain data are collected, and the positioning of the abnormal strain data is inaccurate due to the influence of high-temperature environment on the outdoor optical cable line, the temperature influence factor is considered by setting the fault positioning model, the environment of the optical cable line is obtained through the optical cable line information to determine whether the positioning deviation calculation needs to be performed, and the position of the optical cable with abnormal strain data is recalculated through the preset deviation calculation rule, so that the influence of the environmental temperature on the positioning of the optical cable position damaged by external force is greatly eliminated, the target positioning information received by the operation and maintenance terminal is more accurate, the accuracy of the positioning of the abnormal position of the strain parameters in the optical fiber link is improved, and the situation that the optical cable is irreversibly damaged by external force is reduced.

[0013] Optionally, when the fault positioning model receives the abnormal strain data, the optical cable line information corresponding to the abnormal strain data is identified, including:

[0014] When the fault positioning model receives the abnormal strain data, the optical cable model identifier corresponding to the abnormal strain data is extracted from the abnormal strain data.

[0015] The complete line information of the optical cable is obtained based on the optical cable model identifier, and the complete line information is composed of a plurality of optical cable segment information.

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

[0017] By adopting the technical scheme, the abnormal strain data corresponding to different optical cable lines are different, so the optical cable model needs to be obtained to identify the optical cable line, and further, since the optical cable line is long and the environment of the optical cable is complex, in order to make the judgment and calculation of the positioning deviation calculation more accurate, the complete optical cable line is divided into a plurality of optical cable segments, that is, optical cable segment information.

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

[0019] The current optical cable temperature data of each piece of screened optical cable segment information is obtained.

[0020] The fault positioning model calls the temperature threshold value of the corresponding optical cable line information, and compares the temperature threshold value with the temperature data, and judges whether to perform the positioning deviation calculation based on the comparison result of all optical cable segment information.

[0021] By adopting the technical scheme, for the judgment of whether to perform the positioning deviation calculation, the temperature of each section of the distinguished optical cable line needs to be obtained and compared with the temperature threshold to obtain a plurality of comparison results, so that the stability of the positioning deviation calculation is improved, and rich input data is provided for the subsequent deviation calculation rule, so that the calculation of the positioning deviation value is more accurate.

[0022] Optionally, the judgment of whether to perform the positioning deviation calculation based on the comparison results of all the optical cable section information comprises:

[0023] When any one of the comparison results is met, the positioning deviation calculation is performed.

[0024] When the temperature data of any one or more of the optical cable section information is greater than the temperature threshold, and the temperature difference is greater than or equal to a preset range value.

[0025] And / or,

[0026] When the number of the optical cable section information whose temperature data is greater than the temperature threshold is greater than or equal to a preset number value.

[0027] By adopting the technical scheme, when the temperature data of one section of the optical cable line in the optical cable section information is greater than the temperature threshold and the temperature difference is greater than the range value, it is proved that the temperature of the section of the optical cable line is too large and the optical cable position positioning of the strain abnormal data that appears when the default serious influence occurs. Therefore, even if there is one section of the optical cable section information whose temperature data is greater than the temperature threshold, the positioning deviation value calculation should be performed. Another case is that the number of the optical cable section 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 sections are in a relatively high temperature state, so the overall optical cable position positioning of the strain abnormal data is greatly affected. Therefore, the positioning deviation value calculation also needs to be performed.

[0028] Optionally, when the positioning deviation calculation needs to be performed, the corresponding deviation calculation rule in the fault positioning model is called based on the basic positioning information and the optical cable line information, and the positioning deviation value is outputted. Comprises:

[0029] When the positioning deviation calculation needs to be performed, all the optical cable section information whose temperature data is greater than the temperature threshold is obtained in the optical cable line information.

[0030] The fault positioning model calls the deviation calculation rule matched with the optical cable line information.

[0031] The temperature difference corresponding to each section of the optical cable section information is inputted into the deviation calculation rule, and the positioning deviation value is calculated.

[0032] By adopting the technical scheme, the deviation calculation rule needs to be matched with the optical cable line information, that is, matched according to the optical cable model identifier, and the deviation calculation rule needs to be calculated for each optical cable segment information with the temperature data greater than the temperature threshold. During the calculation, the multiple temperature differences cooperate with the corresponding optical cable segments, the analysis of the temperature influence on the optical cable line information is more comprehensive and meticulous, which helps to improve the accuracy of the positioning deviation value calculation.

[0033] Optionally, the temperature difference value corresponding to each optical cable segment information is input into the deviation calculation rule, and a positioning deviation value is calculated, including:

[0034] The received temperature difference value is arranged in sequence according to the order from the optical fiber sensing terminal to the position where the strain abnormal data appears, to obtain distribution data of the temperature difference value.

[0035] The fault positioning model identifies a distribution form similar to the distribution data from the preset database, and obtains a deviation value matched with the distribution form.

[0036] Based on the distribution form and the distribution data, the deviation value is differentially adjusted, and a final positioning deviation value is output.

[0037] By adopting the technical scheme, since the basic positioning information refers to the distance from the position where the optical cable has stress change abnormality to the optical fiber sensing terminal, the distance is greatly affected by the environmental temperature along the optical cable, and the temperature difference value is arranged according to the order from the optical fiber sensing terminal to the position where the strain abnormal data appears, the temperature difference value distribution along the optical cable can be obtained. The fault positioning model identifies the distribution data of the temperature difference value from the preset database, finds one most similar to the current distribution data from the temperature difference value distribution form of the past simulation experiment, and obtains a deviation value matched with the distribution form. However, there are also some deviations in the similar distribution trend, so the deviation value of the most similar distribution form is adjusted by differential adjustment, and finally the positioning deviation value corresponding to the current temperature difference distribution data is obtained.

[0038] Optionally, the basic positioning information and the positioning deviation value are combined, and target positioning information is output to the operation and maintenance terminal, including:

[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 position where the strain abnormal data is located and the position where the optical fiber sensing terminal is located. The adjustment of the positive positioning deviation value and the negative positioning deviation value represents that the displacement directions along the optical cable line are opposite, and are converted into longitude and latitude data to obtain the target positioning information.

[0040] By adopting the technical scheme, 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 position where the strain abnormal data occurs, and then the distance is converted into latitude and longitude data to output target positioning information, so that the position of the optical cable where the strain abnormal data occurs is adjusted, and the operation and maintenance terminal can also find the corresponding stress fault point.

[0041] The second application purpose is achieved by the following technical scheme:

[0042] An intelligent monitoring system for preventing optical cables from being damaged by external forces includes:

[0043] A data receiving module is configured to send strain abnormal data to a pre-trained fault positioning model when the strain abnormal data is received from an optical fiber sensing terminal, and the strain abnormal data includes basic positioning information of strain parameters provided by the optical fiber sensing terminal.

[0044] A line identification module is configured to identify optical cable line information corresponding to the strain abnormal data when the fault positioning model receives the strain abnormal data.

[0050] The fourth application purpose is achieved by the following technical scheme:

[0051] A computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement the steps of the above-described intelligent monitoring method for preventing optical cables from being damaged by external forces.

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

[0053] 1. By setting the fault positioning model to consider the factors of temperature influence, 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, and further through the preset deviation calculation rule, the optical cable position with abnormal strain data is recalculated, thereby greatly eliminating the influence of environmental temperature on the positioning of optical cable position damaged by external force, the target positioning information received by the operation and maintenance terminal is more accurate, the accuracy of positioning the abnormal position of strain parameters in the optical fiber link is improved, and the situation that the optical cable is irreversibly damaged by external force is reduced;

[0054] 2. Different optical cable lines correspond to different strain abnormal data, so the optical cable model needs to be obtained to identify the optical cable line, and further, since the optical cable line is long and the environment of the optical cable is complex, in order to make the judgment and calculation of positioning deviation calculation more accurate, the complete optical cable line is divided into several optical cable sections, i.e. optical cable section information;

[0055] 3. When the temperature data of a section of optical cable line in the optical cable section information is greater than the temperature threshold value and the temperature difference value is greater than the extreme value, it is proved that the temperature of the section of optical cable line is too large and reaches the default serious influence of the optical cable position with abnormal strain data, so even if there is a section of optical cable section information with temperature data greater than the temperature threshold value, positioning deviation value calculation should be performed;

[0056] 4. The fault positioning model identifies the distribution data of the temperature difference value from the preset database, can find one most similar to the current distribution data from the temperature difference value distribution form of the past simulation experiment, obtains the deviation value matched with the distribution form, but there will also be some deviation in the distribution trend, so the deviation value of the most similar distribution form is adjusted through differential adjustment, and finally the positioning deviation value corresponding to the current temperature difference distribution data is obtained.

[0061] The following will be described in combination with the accompanying Figures 1-4The application is further described in detail.

[0062] In the embodiments, as shown in Figure 1 The application discloses an intelligent monitoring method for preventing optical cables from being damaged by external forces, and specifically comprises the following steps:

[0063] S10: When receiving strain abnormal data sent by the optical fiber sensing terminal, the strain abnormal data is sent to a pre-trained fault positioning model, and the strain abnormal data comprises basic positioning information of strain parameters given by the optical fiber sensing terminal;

[0064] In the embodiment, the optical fiber sensing terminal is an optical fiber sensor, the strain abnormal data comprises strain parameters changed when the optical cable is damaged by external forces, distance data obtained by measuring the round-trip time of pulse light through the optical fiber sensor, and basic positioning information obtained by positioning conversion according to the distance data, and the currently obtained basic positioning information does not consider the influence of environmental temperature on the optical cable.

[0065] The fault positioning model is a model for judging whether the position of the optical cable with the strain abnormal data needs to be adjusted and positioned by training a neural network.

[0066] S20: When the fault positioning model receives the strain abnormal data, the optical cable line information corresponding to the strain abnormal data is identified;

[0067] In the embodiment, the optical cable line information comprises an identifier for identifying a specific optical cable line, and the judgment parameters of the fault positioning model for optical cables of different materials and specifications are inconsistent.

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

[0069] S21: When the fault positioning model receives the strain abnormal data, the optical cable model identifier corresponding to the strain abnormal data is extracted from the strain abnormal data;

[0070] S22: Complete line information of the optical cable is obtained based on the optical cable model identifier, and 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 position where the strain abnormal data occurs is screened out as the optical cable line information.

[0072] In the embodiment, the optical cable model identifier is used to identify the specific material and specification of the optical cable line, the complete line information is the complete optical cable line, and the plurality of optical cable segment information represents that the complete optical cable line is divided into a plurality of optical cable segments by self-definition, which is usually divided according to length or environmental topography.

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

[0074] S30: judging whether to perform the positioning deviation calculation based on the cable line information;

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

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

[0077] The judging whether to perform the positioning deviation calculation based on the cable line information includes:

[0078] S31: acquiring the current cable temperature data of each piece of the screened cable segment information;

[0079] S32: the fault positioning model calls the temperature threshold value corresponding to the cable line information, and compares the temperature data, and judges whether to perform the positioning deviation calculation based on the comparison results of all the cable segment information.

[0080] In the embodiment, the temperature data corresponding to each piece of the cable segment information can be acquired by installing temperature sensors on the surface of each piece of the cable and small processors connected by signals. In other embodiments, for long-distance cable lines, the temperature of the geographical position of the cable segment can be acquired to make the judgment.

[0081] The temperature threshold value is set by multiple simulation experiments, and the temperature data greater than the temperature threshold value represents that the temperature data at this time will affect the accuracy of the basic positioning information.

[0082] The comparison results of all the cable segment information are used to judge whether to perform the positioning deviation calculation, wherein the positioning deviation calculation is performed when any one of the following comparison results is met:

[0083] When the temperature data of any one or more pieces of the cable segment information is greater than the temperature threshold value, and the temperature difference is greater than or equal to a preset difference value, the difference value is set by multiple simulation experiments.

[0084] and / or,

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

[0086] When the number of cable segment information whose temperature data is greater than the temperature threshold value is less than the preset number value, and the temperature difference value between the temperature data and the temperature threshold value is less than the range value, it is judged that the positioning deviation calculation is not needed to be performed.

[0087] S40: When the positioning deviation calculation is needed to be performed, the corresponding deviation calculation rule in the fault positioning model is called based on the basic positioning information and the cable line information, and the positioning deviation value is outputted.

[0088] In the embodiment, the fault positioning model needs to obtain the model identification of the cable from the cable line information, to know the material and specification of the cable line to judge the influence range of the environmental temperature on the positioning of the cable line, so as to call the corresponding deviation calculation rule. The deviation calculation rule is used to filter out the approximate distribution state from the database according to the distribution of the temperature difference value of each cable segment information, so as to output the positioning deviation value according to the deviation adjustment recommendation scheme stored by the simulation experiment.

[0089] Specifically, referring to Figure 3 , the step S40 includes the steps of:

[0090] S41: When the positioning deviation calculation is needed to be performed, all cable segment information whose temperature data is greater than the temperature threshold value is obtained in the cable line information.

[0091] S42: The fault positioning model calls the deviation calculation rule matched with the cable line information.

[0092] S43: The temperature difference value corresponding to each cable segment information is inputted into the deviation calculation rule, and the positioning deviation value is calculated.

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

[0094] After the deviation calculation rule receives the temperature difference value corresponding to the several cable segment information, the received temperature difference value is arranged in order according to the order from the optical fiber sensing terminal to the position where the strain abnormal data appears, to obtain the distribution data of the temperature difference value.

[0095] The fault positioning model identifies the distribution form approximate to the distribution data from the preset database, and obtains the deviation value matched with the distribution form. The preset database stores various temperature difference value distribution forms obtained by the simulation experiment in the past. The distribution form approximate to the distribution data needs to consider the order of the temperature difference value and the change of the previous and subsequent values.

[0096] Further based on the distribution pattern and the distribution data, the bias value is adjusted differently and the final positioning bias value is outputted. The adjustment is based on the temperature difference between adjacent points and the amplitude of the change in the temperature difference. For example, the temperature difference changes little in the distribution data and is greater than the temperature difference in the pre-stored distribution pattern, and the bias value is adjusted to be larger. The obtained positioning bias value is larger than the bias value of the pre-stored distribution pattern.

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

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

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

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