[0002] Remote positioning refers to accurately determining the geographical position information of an optical cable joint box without directly contacting the optical cable joint box through specific technical means. The optical cable joint box is a key component in an optical cable line, which is used to connect two or more optical cables, protect the optical fiber joint from external environmental factors, and ensure the stable connection between optical fibers and reliable transmission of signals.

[0003] Traditional optical cable joint box fault detection mainly relies on manual regular inspection. Maintenance personnel need to check the appearance and running state of the joint box along the optical cable line one by one. This way not only consumes a lot of manpower, material resources and time, but also has a long inspection cycle, making it difficult to discover potential fault hazards in time. Secondly, manual inspection can only obtain the state information of the joint box at a specific time point, and cannot realize real-time monitoring of the running state.

[0075] Referring to Figure 1 FIG. 1 shows a flowchart of a method for identifying faults of optical cable joint boxes based on remote positioning provided in an embodiment of the application. In this embodiment, the method for identifying faults of optical cable joint boxes based on remote positioning includes:

[0076] S1, receiving a fault identification instruction, constructing a fault parameter detection system, and obtaining an optical cable joint box set and a backup optical cable joint box set according to the fault identification instruction.

[0077] It should be explained that the fault identification instruction is an instruction issued by an operator to trigger a series of operation processes for identifying the fault of the optical cable joint box. The optical cable joint box set refers to a set of optical cable joint boxes in use. The standby optical cable joint box set refers to a set of optical cable joint boxes in standby state prepared in advance to cope with the situation of optical cable joint box failure or damage. The standby optical cable joint box in the embodiment of the application matches the joint box in use in terms of specifications, performance, etc., so as to quickly replace the failed joint box when needed, reduce the fault repair time, reduce the impact on communication services, and improve the reliability and stability of the communication network.

[0078] In detail, the construction of the fault parameter detection system includes:

[0079] The historical fault detection period is obtained, the pre-constructed historical optical cable joint box is detected according to the historical fault detection period, and a detection data set is obtained, wherein the detection data set includes historical temperature data, light intensity data, mechanical stress data and chemical data;

[0080] The thermal field parameters are extracted from the historical temperature data, wherein the thermal field parameters include temperature gradient and thermal conductivity;

[0081] The optical field parameters are extracted from the light intensity data, wherein the optical field parameters include light intensity value and absorption coefficient;

[0082] The force field parameters are extracted from the mechanical stress data, wherein the force field parameters include stress tensor and body force;

[0083] The chemical field parameters are extracted from the chemical data, wherein the chemical field parameters include chemical concentration and chemical reaction rate;

[0084] The optical-mechanical-thermal-chemical four-field coupling equation is constructed based on the thermal field parameters, the optical field parameters, the force field parameters and the chemical field parameters, wherein the optical-mechanical-thermal-chemical four-field coupling equation is expressed as:

[0085] wherein, represents a preset Laplace algorithm, represents a preset electric field intensity, represents a preset magnetic permeability, represents a preset dielectric constant, represents the second-order derivative of the electric field with respect to time, represents a preset material density, represents a preset material specific heat capacity, represents the rate of change of temperature with respect to time, represents thermal conductivity, represents temperature gradient, represents absorption coefficient,​ Indicates the light intensity value. Represents the stress tensor. Represents volume force. Indicates chemical concentration. This represents the preset diffusion coefficient. Laplace's expression for concentration, Indicates the rate of a chemical reaction. Represents the vector differential operator. This represents the rate of change of chemical concentration over time.

[0086] A fault parameter detection system is constructed based on the optical-mechanical-thermal-chemical four-field coupling equation.

[0087] It should be explained that the historical fault detection period refers to the time period selected for past fault detection of optical cable splice boxes. Historical optical cable splice boxes refer to those that have been installed and put into use in the past. The purpose of selecting historical optical cable splice boxes in this embodiment of the invention is that these boxes have undergone a certain period of operation, accumulating various operational data and fault information. Detecting these historical splice boxes allows for the acquisition of data on their performance under different operating conditions, including temperature changes, optical signal transmission, mechanical stress resistance, and chemical changes. This helps to summarize the patterns and characteristics of potential faults in the optical cable splice boxes, thereby providing data support and model verification for new fault detection systems. Historical temperature data refers to the temperature data obtained by detecting historical optical cable splice boxes during the historical fault detection period.

[0088] Importantly, mechanical stress data refers to data related to various mechanical forces experienced by the fiber optic splice closure during use. For example, mechanical forces include compression and torsion. Chemical data refers to data on chemical substances inside and around the fiber optic splice closure. Thermal field parameters are parameters composed of temperature gradient, thermal conductivity, material specific heat capacity, and material density. Temperature gradient refers to the change in temperature per unit distance. In a fiber optic splice closure, the temperature gradient can reflect the direction and intensity of heat transfer. For example, if there is a local heat source inside the fiber optic splice closure, it will cause the surrounding temperature to rise, forming a temperature gradient. An abnormal temperature gradient may indicate poor heat dissipation or a localized fault inside the splice closure. Thermal conductivity is a coefficient that measures the material's ability to conduct heat. Materials with higher thermal conductivity can dissipate heat more quickly, thereby reducing the temperature inside the fiber optic splice closure. Material specific heat capacity refers to the amount of heat absorbed by a unit mass of material to increase its temperature by a unit. Material density is the ratio of the material's mass to its volume. The specific heat capacity and material density of the materials described in this embodiment of the invention are obtained from the material specifications of the fiber optic splice closure.

[0089] It should be explained that the dielectric constant and the magnetic permeability are obtained from the material manual of the optical cable joint box. The stress tensor refers to a physical quantity reflecting the mechanical stress state of the material inside the optical cable joint box. The body force refers to the force acting on each volume element of the optical cable joint box. For example, the body force is: gravity, inertial force, etc. The body force will affect the material inside the optical cable joint box, which may cause deformation or damage of the material. The diffusion coefficient refers to the coefficient of the diffusion ability of the chemical substance in the material inside the optical cable joint box. The larger the diffusion coefficient, the faster the diffusion speed of the chemical substance. The absorption coefficient refers to the coefficient of the absorption characteristics of the light by the material inside the optical cable joint box. If the absorption coefficient is too large, it will cause too much loss of the optical signal during transmission, affecting the communication performance of the optical cable.

[0090] S2, sequentially extract one optical cable joint box from the optical cable joint box set, and perform the following operations on the extracted optical cable joint box: obtain a set of fault monitoring time periods, obtain a set of area difference values and a set of gas data based on the fault parameter detection system, the optical cable joint box and the set of fault monitoring time periods, wherein the fault monitoring time period corresponds to the area difference value and the gas data one by one.

[0091] It should be explained that the set of fault monitoring time periods refers to a set of monitoring time periods set by humans.

[0092] In detail, the set of area difference values and the set of gas data based on the fault parameter detection system, the optical cable joint box and the set of fault monitoring time periods are obtained, including:

[0093] Sequentially extract one fault monitoring time period from the set of fault monitoring time periods, and perform the following operations on the extracted fault monitoring time period:

[0094] The optical cable joint box is monitored by using the fault parameter detection system and the fault monitoring time period to obtain temperature data and chemical concentration data, wherein the chemical concentration data includes a plurality of chemical concentration values;

[0095] If there is a chemical concentration value greater than the preset chemical concentration threshold value in the chemical concentration data, the chemical concentration value greater than the preset chemical concentration threshold value is recorded as an abnormal concentration value, and the abnormal concentration values are summarized to obtain a plurality of abnormal concentration values, and the number of abnormal concentration values of the plurality of abnormal concentration values is confirmed.

[0096] If the number of abnormal concentration values is greater than the preset number of standard abnormal values, the optical cable joint box corresponding to the chemical concentration data is monitored for toxic gas to obtain gas data;

[0097] Draw a temperature curve based on the temperature data, wherein the horizontal axis of the temperature curve is time and the vertical axis of the temperature curve is temperature value;

[0098] The historical temperature curve is obtained according to a preset historical failure monitoring time period, the temperature area is obtained based on the temperature curve, and the historical temperature area is obtained based on the historical temperature curve, wherein the historical failure monitoring time period has the same length as that of the failure monitoring time period;

[0099] The historical temperature area and the temperature area are subjected to a subtraction operation to obtain an area difference value, and the area difference value and the gas data are summarized to obtain an area difference value set and a gas data set corresponding to the failure monitoring time period set.

[0100] It should be explained that the failure monitoring time period refers to a time period in the failure monitoring time period set. The abnormal concentration value refers to a chemical concentration value greater than a preset chemical concentration threshold value in the monitored chemical concentration data. The chemical concentration threshold value refers to a preset threshold value. The abnormal concentration value quantity refers to the number of abnormal concentration values obtained in one failure monitoring time period. The standard abnormal value quantity is a preset quantity for judging whether the chemical concentration data is abnormal. The toxic gas monitoring on the optical cable joint box corresponding to the chemical concentration data refers to the toxic gas monitoring on the optical cable joint box corresponding to the chemical concentration data by using a gas sensor. The temperature curve drawn based on the temperature data refers to the temperature data being imported into drawing software, and the temperature curve being drawn by using the drawing software. For example, the drawing software includes Origin, GraphPad Prism, etc. The drawing of the temperature curve by using the drawing software is prior art, which will not be described herein.

[0101] It can be understood that the historical fault monitoring time period refers to a past time period with the same length as the current fault monitoring time period. For example, the current fault monitoring time period is 10:00-11:00 on March 10, 2025, and the historical fault monitoring time period is 10:00-11:00 on February 10, 2025. The historical temperature curve refers to a temperature curve drawn based on temperature data obtained in the historical fault monitoring time period. The drawing method of the historical temperature curve is the same as the method of drawing the temperature curve based on the current temperature data, that is, taking time as the horizontal axis and temperature value as the vertical axis, marking the temperature value of each time point in the historical fault monitoring time period in the coordinate system and connecting them into a curve. Through the historical temperature curve, the temperature change of the cable joint box in the same past time period can be understood. The area difference value is the difference between the historical temperature area and the temperature area. The area difference value reflects the difference between the temperature change in the current fault monitoring time period and the historical period. The greater the area difference value, the more different the current temperature change is from the historical situation, indicating that the cable joint box is abnormal. The area difference value set refers to a set formed by collecting the area difference values corresponding to each fault monitoring time period. The gas data refers to a set formed by collecting the gas data obtained by monitoring the toxic gas of the cable joint box when the number of abnormal concentration values in each fault monitoring time period is greater than the number of standard abnormal values.

[0102] In detail, the temperature area is obtained based on the temperature curve, comprising:

[0103] A fitting model is selected according to the temperature curve, an initial temperature function is fitted according to the fitting model and the temperature curve, the initial temperature function is parameterized by using a pre-constructed least square method, function parameters are obtained, and a fitting temperature function is confirmed according to the function parameters and the initial temperature function;

[0104] A fitting goodness index of the fitting temperature function is calculated, and the fitting goodness index is compared with a preset standard goodness index;

[0105] If the fitting goodness index is greater than the preset standard goodness index, the step of selecting the fitting model according to the temperature curve is returned to until the fitting goodness index is less than or equal to the preset standard goodness index;

[0106] If the fitting goodness index is less than or equal to the preset standard goodness index, the fitting temperature function corresponding to the fitting goodness index is taken as the temperature function;

[0107] An initial time and an end time are obtained according to the temperature curve, and an integral operation is performed on the temperature function according to the initial time and the end time to obtain the temperature area, wherein the integral operation is represented as:

[0108] ;

[0109] wherein, represents a temperature area, represents an initial time, represents an end time, represents a temperature function.

[0110] It should be explained that the selecting a fitting model according to the temperature curve refers to judging the curve characteristics of the temperature curve by using a computer system, so as to select a fitting model. For example, the fitting model is a linear model, a quadratic model, an exponential model, a logarithmic model, etc. The step of fitting the initial temperature function according to the fitting model and the temperature curve is prior art, and will not be described here. The function parameter refers to an unknown parameter that needs to be determined in the fitting model. The least square method refers to a commonly used parameter evaluation method, which is to minimize the sum of squares of errors between actual values and predicted values of the fitting function. The confirming the fitting temperature function according to the function parameter and the initial temperature function refers to substituting the obtained function parameter into the initial temperature function to obtain the fitting temperature function. The fitting goodness index of the fitting temperature function refers to an index for measuring the fitting degree of the fitting temperature function to the temperature curve. For example, the fitting goodness index is a determination coefficient, a mean square error, a root mean square error, etc. The initial temperature function refers to a function that is fitted according to the fitting model and the temperature curve without determining the function parameter.

[0111] It can be understood that the standard goodness index is a pre-set index for judging whether the fitting goodness index of the fitting temperature function is less than or equal to the standard goodness index.

[0113] In detail, the performing an optimization operation on the optical cable joint box and the set of spare optical cable joint boxes based on the set of area difference values, to obtain an optimal set of optical cable joint boxes and a replacement optical cable joint box, comprises:

[0114] judging whether there is an area difference value greater than a pre-set area difference threshold value in the set of area difference values;

[0115] If it is confirmed that there is an area difference value greater than the pre-set area difference threshold value in the set of area difference values, a temperature abnormal area is identified according to the temperature data of the temperature curve corresponding to the area difference value greater than the pre-set area difference threshold value, and a thermal expansion coefficient of the temperature abnormal area is calculated;

[0116] A thermal expansion amount is obtained according to the thermal expansion coefficient, a maximum stress value of the temperature abnormal area is obtained according to the thermal expansion amount, and the maximum stress value is compared with a pre-set material yield strength;

[0117] If the maximum stress value is greater than the preset material yield strength, the target geographic coordinates of the optical cable joint box corresponding to the maximum stress value are obtained, a standby optical cable joint box is extracted from the standby optical cable joint box set according to the target geographic coordinates, the reserved standby optical cable joint boxes are summarized to obtain an updated optical cable joint box set;

[0118] The optical cable joint box is replaced by the extracted standby optical cable joint box to obtain a replacement optical cable joint box, and the updated optical cable joint box set is optimized according to the maximum stress value to obtain an optimal optical cable joint box set;

[0119] If the maximum stress value is less than or equal to the preset material yield strength, the optical cable joint box corresponding to the maximum stress value is recorded as the replacement optical cable joint box, and the updated optical cable joint box set is recorded as the optimal optical cable joint box set.

[0120] It should be explained that the area difference threshold is a preset value for distinguishing the normal temperature of the optical cable joint box and the temperature with problems. The temperature abnormal area refers to the area of the temperature data of the temperature curve corresponding to the area difference value greater than the preset area difference threshold. The material yield strength refers to the strength that the material of the optical cable joint box can withstand when it begins to produce obvious plastic deformation. The target geographic coordinates of the optical cable joint box corresponding to the maximum stress value are obtained by equipping a positioning device when each optical cable joint box is installed, and the geographic coordinates of the optical cable joint box corresponding to the maximum stress value are obtained according to the positioning device. For example, the positioning device is a GPS. The updated optical cable joint box set refers to the set of remaining standby optical cable joint boxes after selecting the standby optical cable joint box from the standby optical cable joint box set when it is confirmed that the maximum stress value of a certain optical cable joint box is greater than the preset material yield strength. The replacement optical cable joint box refers to the optical cable joint box used to replace the optical cable joint box whose maximum stress value exceeds the material yield strength by using the standby optical cable joint box extracted from the standby optical cable joint box set. The optimal optical cable joint box set is obtained by optimizing the updated optical cable joint box set according to the maximum stress value, which refers to selecting a material with higher strength and better thermal performance to manufacture the standby optical cable joint box according to the size of the maximum stress value, analyzing the cause of the maximum stress, and improving the structure of the updated optical cable joint box set, thereby obtaining the optimal optical cable joint box set. For example, if the stress concentration is caused by thermal expansion, the internal structure of the joint box can be optimized, heat dissipation channels can be increased, or a stretchable structure design can be adopted to reduce the stress caused by thermal expansion.

[0121] In detail, the calculation of the thermal expansion coefficient of the temperature abnormal area includes:

[0122] The thermal expansion coefficient of the temperature abnormal area is calculated by using a pre-constructed thermal expansion coefficient formula, wherein the thermal expansion coefficient formula is as follows:

[0123] ;

[0124] wherein, represents a thermal expansion coefficient, represents a preset material length, represents a change amount of the temperature abnormal area.

[0125] It should be explained that the thermal expansion coefficient refers to the length change rate of the material of the cable joint box per unit length when the temperature is increased (or decreased) by one unit temperature. The material length refers to the length corresponding to the temperature abnormal area on the cable joint box.

[0126] In detail, the method according to the thermal expansion coefficient to obtain the thermal expansion amount, according to the thermal expansion amount to obtain the maximum stress value of the temperature abnormal area, comprises:

[0127] obtaining the temperature change amount of the temperature abnormal area, and calculating the thermal expansion amount according to the thermal expansion coefficient and the temperature change amount, wherein the calculation formula of the thermal expansion amount is as follows:

[0130] determining the material elastic modulus of the cable joint box, and calculating the stress value corresponding to each temperature value in the temperature abnormal area according to the material elastic modulus, the thermal expansion coefficient and the temperature change amount, wherein the calculation formula of the stress value is as follows:

[0131] ;

[0132] wherein, represents a stress value, represents a material elastic modulus;

[0133] summarizing the stress values to obtain a stress value set, and extracting the maximum stress value from the stress value set.

[0134] It should be explained that the temperature change amount refers to the temperature change value of the temperature curve corresponding to the temperature anomaly area in a certain time period. The thermal expansion amount refers to the length change amount of the material of the cable joint box due to temperature change. The material modulus of elasticity of the cable joint box is determined by consulting the material manual of the cable joint box. The material modulus of elasticity refers to the difficulty of elastic deformation of the material under stress. The greater the material modulus of elasticity, the more difficult the material is to elastically deform. The stress value set refers to a set of stress values corresponding to each temperature value in the temperature anomaly area. The maximum stress value extracted from the stress value set refers to sequentially extracting a stress value from the stress value set, and comparing the extracted stress value with the adjacent next stress value, thereby obtaining the maximum stress value. For example, the stress value set is {12.5, 15.3, 9.8, 12.5}, the first stress value 12.5 is extracted from the stress value set, and 12.5 is compared with {15.3, 9.8, 12.5}, two 12.5 are obtained, and the first stress value in the stress value set is taken as the maximum stress value.

[0135] S4, sequentially extract gas data from the gas data set, and perform the following operation on the extracted gas data: if it is confirmed that there is data in the gas data that is not located in the preset gas interval, obtain the geographic coordinates of the cable joint box corresponding to the gas data, and extract a spare cable joint box from the spare cable joint box set.

[0136] It should be explained that the gas data set refers to a set composed of all gas data. The gas interval refers to a preset interval for ensuring that the gas data is within a normal range. The purpose of the gas interval is to quickly identify whether the gas environment is abnormal by judging whether the gas data is located in the preset gas interval. If it is found that the gas data is not in the preset gas interval, timely measures can be taken to ensure the stability of the optical cable communication. The method for obtaining the geographic coordinates of the cable joint box corresponding to the gas data is the same as the method for obtaining the geographic coordinates of the cable joint box corresponding to the maximum stress value, and will not be described here.

[0137] S5, replace the replaced cable joint box according to the geographic coordinates and the spare cable joint box, to obtain a replacement cable joint box, wherein the replacement cable joint box includes one or more.

[0138] In detail, the replacement of the replaced cable joint box according to the geographic coordinates and the spare cable joint box to obtain a replacement cable joint box includes:

[0139] Obtain the vehicle coordinates of the maintenance vehicle, generate a plurality of maintenance paths according to the geographic coordinates and the vehicle coordinates, and obtain a required maintenance time group of the plurality of maintenance paths, wherein the maintenance path and the required maintenance time correspond one by one;

[0140] If it is confirmed that there is a required maintenance time greater than the preset maintenance time threshold in the required maintenance time group, the maintenance path corresponding to the required maintenance time greater than the preset maintenance time threshold is removed, and the remaining maintenance paths are summarized to obtain a plurality of updated maintenance paths;

[0141] For each of the plurality of updated maintenance paths, the following operations are performed:

[0142] The completion maintenance time, path length, replacement cost and environmental impact of the updated maintenance path are obtained, and the total reward value of the updated maintenance path is calculated according to the completion maintenance time, path length, replacement cost and environmental impact;

[0143] The total reward values are summarized to obtain a total reward value group, the maximum total reward value is extracted from the total reward value group, and the optical cable joint box is replaced according to the updated maintenance path corresponding to the maximum total reward value to obtain a replaced optical cable joint box.

[0144] It should be explained that the step of obtaining the vehicle coordinates of the maintenance vehicle is to obtain and record the coordinate information of the vehicle in real time according to the GPS device on the maintenance vehicle, and then the coordinate information can be sent to the system of the management center through the information transmission module on the maintenance vehicle to obtain the vehicle coordinates. The generation of a plurality of maintenance paths according to the geographic coordinates and the vehicle coordinates means that the geographic coordinates and the vehicle coordinates are introduced into a map navigation algorithm to generate a plurality of maintenance paths. The map navigation algorithm in the embodiment of the application refers to a calculation method for planning an optimal path from a starting point to an ending point on a map, which is prior art and will not be described here. The replacement cost refers to the cost including the labor cost, the material cost and the vehicle use cost. The environmental impact refers to the impact of the carbon dioxide emission generated by the maintenance vehicle during driving according to the type of the maintenance vehicle and the path length. The total reward value group refers to a set of total reward values corresponding to each updated maintenance path. The maximum total reward value refers to the total reward value with the largest value extracted from the total reward value group. By selecting the path corresponding to the maximum total reward value to replace the optical cable joint box, the maintenance efficiency can be ensured while the cost is reduced and the impact on the environment is reduced as much as possible. The replaced optical cable joint box refers to the optical cable joint box obtained by arranging the maintenance vehicle and the maintenance personnel to go to the location of the optical cable joint box according to the updated maintenance path corresponding to the maximum total reward value, and using the spare optical cable joint box to replace the optical cable joint box with problems.

[0145] In detail, the calculation of the total reward value of the updated maintenance path according to the completion maintenance time, path length, replacement cost and environmental impact includes:

[0146] The total reward value of the updated maintenance path is calculated according to the completion maintenance time, path length, replacement cost and environmental impact, and the calculation formula of the total reward value is as follows:

[0147] ;

[0148] wherein, represents the total reward value, represents a preset path coefficient, represents the path length, represents a preset time coefficient, represents the completion maintenance time, represents a preset resource utilization rate, represents a preset resource coefficient, represents a preset cost coefficient, represents the replacement cost, represents a preset environmental coefficient, represents the environmental impact, represents a natural exponential function.

[0149] It should be explained that the total reward value is a quantitative index for comprehensively evaluating the advantages and disadvantages of the updated maintenance path, which is obtained by combining the completion maintenance time, path length, resource utilization rate, replacement cost and environmental impact factors. The path coefficient is a coefficient that is preset to reflect the influence degree of the path length on the total reward value. The greater the path coefficient, the greater the influence of the path length on the total reward value. The time coefficient is a coefficient that is preset to reflect the urgency of the completion maintenance time. The greater the time coefficient, the more urgent the completion maintenance time. The resource utilization rate refers to the utilization efficiency of various resources (such as maintenance tools, spare optical cable joint boxes, manpower, etc.) in the maintenance process. The higher the resource utilization rate means that resources can be more effectively utilized in the maintenance process, reducing waste. The resource coefficient is a coefficient that is preset to reflect the influence degree of the resource utilization rate on the total reward value. The greater the resource coefficient, the greater the influence of the resource utilization rate on the total reward value. The cost coefficient is a coefficient that is preset to reflect the influence degree of the replacement cost on the total reward value. The greater the cost coefficient, the greater the influence of the replacement cost on the total reward value.

The optimal optical cable joint box set group obtained through optimization can better adapt to complex environmental conditions and working pressure, and it reduces the possibility of damage to the optical cable joint box caused by environmental factors (such as thermal expansion caused by temperature change), making the entire communication network more reliable and ensuring the normal communication needs of users. At the same time, the optimal optical cable joint box set is strictly screened and optimized, and its performance and quality are more guaranteed. Using the optimal optical cable joint box can prolong the service life and reduce the replacement frequency, thereby reducing the long-term operation and maintenance cost, reducing the probability of failure, and improving the overall stability of the optical cable network.

The present application extracts a single optical cable joint box in turn to perform operations, which can carefully check each joint box to avoid missing fault hazards and improve the accuracy of fault identification. The fault monitoring time period set is obtained, and the area difference set and the gas data set are obtained in combination with the fault parameter detection system to monitor the state of the optical cable joint box from multiple dimensions. Based on the area difference set, the optical cable joint box and the backup optical cable joint box set are subjected to optimization operations to obtain an optimal optical cable joint box set and a replacement optical cable joint box. Gas data is extracted from the gas data set in turn, and the following operations are performed on the extracted gas data: The present application can screen out optical cable joint boxes with relatively good physical state and small deformation as optimal optical cable joint boxes by analyzing the area difference set. These optical cable joint boxes may be more reliable in terms of performance and reliability, which helps to improve the stability of the entire optical cable network. If it is confirmed that there is data in the gas data that does not belong to the preset gas interval, the geographic coordinates of the replacement optical cable joint box corresponding to the gas data are obtained, a backup optical cable joint box is extracted from the backup optical cable joint box set, the replacement optical cable joint box is replaced according to the geographic coordinates and the backup optical cable joint box, and a replacement optical cable joint box is obtained, wherein the replacement optical cable joint box includes one or more. The present application obtains the geographic coordinates of the fault optical cable joint box, which enables maintenance personnel to quickly find the fault location, reduces the time and workload of fault troubleshooting, and improves the efficiency of fault repair. The backup joint box is extracted from the backup optical cable joint box set for replacement, which can restore the normal operation of the optical cable network in a timely manner after discovering the fault, reduce the communication interruption time caused by the fault, and ensure normal use by users. The optimal optical cable joint box set and the replacement optical cable joint box are respectively aggregated to obtain the optimal optical cable joint box set group and the replacement optical cable joint box set corresponding to the optical cable joint box set. The present application aggregates the optimal optical cable joint box and the replacement optical cable joint box respectively to form corresponding sets, which facilitates unified management and analysis of these data.
