[0040] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments with reference to the accompanying drawings.

[0042] See Figure 1 , which shows the implementation flowchart of a method for modeling an underground cable provided by an embodiment of the present invention. As Figure 1 shown, a method for modeling an underground cable may include:

[0043] S101, obtain a cable data set of a target cable; the cable data set includes parameter values of at least one cable parameter.

[0044] Optionally, during the process of three-dimensional modeling of the target cable, multiple cable parameters are required. The cable parameters may include at least one of design parameters, environmental parameters, operating parameters, or fault parameters. For example, the at least one cable parameter may include specification parameters, fault parameters, and environmental parameters.

[0045] Specifically, the design parameters can be obtained from the design drawings of the target cable and may include design information such as the specification model and location orientation of the target cable. The environmental parameters can be obtained by collecting the environmental information around the target cable and may include environmental information such as the environmental temperature and environmental humidity of the target cable. The operating parameters can be obtained from the upstream and downstream power distribution equipment or the central server of the target cable and may include power consumption parameters such as the operating voltage and operating load of the target cable. The fault parameters can be obtained from the log information of the target cable and may include fault information such as the number of faults, fault location, and fault time of the target cable.

[0046] Exemplarily, the cable data set may include parameter values such as the specification model, location orientation, environmental temperature, number of faults, and fault location of the target cable.

[0047] S102, for each cable parameter, calculate the similarity value between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter.

[0048] Optionally, for each cable parameter, the preset parameter value corresponding to the cable parameter is a representative parameter value of the target cable in a normal state. The preset parameter value corresponding to the cable parameter can be obtained from the historical data of the target cable. For example, if the cable parameter includes the ambient temperature, the preset parameter value is the maximum value or the minimum value or the average value of the historical ambient temperature in the normal state.

[0049] Specifically, for the design parameters, the conventional parameters of the target cable can be used as the preset parameter values of the design parameters. For the environmental parameters, the average value of the historical environmental parameters of the target cable can be calculated as the preset parameter value of the environmental parameters. For the working parameters, the average value of the historical working parameters of the target cable can be calculated, or the maximum value in the historical working parameters can be selected as the preset parameter value of the working parameters. For the fault parameters, the sum of the historical fault parameters of the target cable can be calculated, and the sum value of the historical fault parameters after summation can be used as the preset parameter value of the fault parameters. Specific selection can be made according to the actual situation.

[0050] Exemplarily, if the cable parameter is the ambient temperature, the average value of the historical ambient temperature can be calculated and used as the preset parameter value corresponding to the ambient temperature.

[0051] Optionally, for each cable parameter, the cosine similarity between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter can be calculated as the similarity value. Among them, the value range of the similarity value is [-1, 1]. -1 indicates that the parameter value of the cable parameter is exactly opposite to the direction of the preset parameter value corresponding to the cable parameter, with the greatest difference, and 1 indicates that the parameter value of the cable parameter is exactly the same as the direction of the preset parameter value corresponding to the cable parameter, with the greatest similarity. Or, for each cable parameter, the difference or ratio between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter can be calculated, and the difference or ratio can be used as the similarity value. Or, for each cable parameter, with the preset parameter value corresponding to the cable parameter as the clustering center, the distance between the cable parameter and the clustering center can be calculated as the similarity value. Specific selection can be made according to the actual situation.

[0052] S103. Determine the remaining life of the target cable according to the obtained similarity values of each cable parameter, and construct a three-dimensional model of the target cable based on the remaining life and the cable data set.

[0053] Optionally, the sum of the obtained similarity values of each cable parameter, or the sum of the absolute values of the obtained similarity values of each cable parameter, can be used as the scoring grade of the target cable, and then the remaining life of the target cable can be determined by looking up a table.

[0054] Specifically, the rating level of the target cable can be compared with a preset rating level - life table to determine the remaining life of the target cable by looking up the table. Among them, the preset rating level - life table includes the corresponding relationships between various preset rating levels and the remaining life of the target cable. Each remaining life in this rating level - life table is simulated and confirmed for the target cable in a simulated environment. For example, by simulating the specification model, ambient temperature, number of faults, and fault location of the target cable, etc., the corresponding remaining life of the target cable is obtained.

[0055] Optionally, when the rating level of the target cable is inconsistent with the rating levels in the preset rating level - life table, the rating level in the rating level - life table that is closest to the target cable is selected as the standard. When there are two rating levels in the rating level - life table with the same distance from the rating level of the target cable, the rating level corresponding to the less remaining life in the table is selected as the rating level of the target cable to ensure the maximum remaining life margin of the target cable, which is convenient for timely maintenance or replacement of the target cable. Specifically, it can be selected according to the actual situation.

[0056] Optionally, after determining the remaining life of the target cable, bind this remaining life to the location of the target cable, and input the design parameters, environmental parameters, working parameters, fault parameters, and the location of the target cable into 3D modeling software to construct a 3D model of the target cable, and the remaining life of the target cable can be displayed in this 3D model of the target cable.

[0057] Optionally, after constructing the 3D model of the target cable, monitor the working parameters of the target cable. If the working parameters change, recalculate the remaining life of the target cable and update the 3D model of the target cable to ensure the real - time nature of the 3D model of the target cable. Or, at every preset time interval, recalculate the remaining life of the target cable and update the 3D model of the target cable.

[0058] Specifically, the working parameters of the target cable include the number of faults. If the target cable fails, recalculate the remaining life of the target cable and update the 3D model of the target cable.

[0059] After constructing the 3D model of the target cable, monitor the remaining life of the target cable through this model. If the remaining life of the target cable is lower than the preset life, an alarm signal is sent to remind the staff to timely know the status of the target cable.

[0060] In some embodiments of the present invention, to ensure the reliability of the remaining life calculation, after "obtaining the cable data set of the target cable" in S101, the method may further include: respectively judging the status of each cable parameter; the status of the cable parameter includes a normal state, an abnormal state, or an invalid state.

[0061] Correspondingly, for each cable parameter, calculate the similarity value between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter, including: for each cable parameter in the normal state, calculate the similarity value between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter.

[0062] Optionally, to ensure the reliability of the target cable life calculation, it is necessary to screen the cable data set of the target cable. The screening can be performed by judging the status of each cable parameter. Calculate the remaining life of the target cable using all cable parameters in the normal state.

[0063] Specifically, for each cable parameter in the normal state, calculate the cosine similarity between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter as the similarity value of the cable parameter. Alternatively, calculate the difference between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter as the similarity value of the cable parameter. The specific selection can be made according to the actual situation.

[0064] Optionally, each cable parameter corresponds to a preset range. For each cable parameter: if the parameter value of the cable parameter is within the preset range corresponding to the cable parameter, it is determined that the cable parameter is in the normal state; if the parameter value of the cable parameter is higher than the preset range corresponding to the cable parameter, it is determined that the cable parameter is in the invalid state; if the parameter value of the cable parameter is lower than the preset range corresponding to the cable parameter, it is determined that the cable parameter is in the abnormal state.

[0065] Optionally, for each cable parameter, the preset range corresponding to the cable parameter is the normal range of the cable parameter. If the parameter value of the cable parameter is lower than the preset range, abnormal acquisition may occur, resulting in inaccurate acquisition of the parameter value of the cable parameter. The cable parameters in the abnormal state can be recollected. If the parameter value of the cable parameter is higher than the preset range, it is possible that the target cable does not have this cable parameter, that is, this cable parameter is invalid, and the parameter values of the cable parameters in the invalid state can be excluded. By recollecting or excluding, the cable data set can be further screened, which can improve the reliability of the calculation.

[0066] Each distribution area can correspond to a three-dimensional cable model. To ensure the consistency of the three-dimensional cable models established in different distribution areas and facilitate data exchange, in some embodiments of the present invention, after obtaining the cable data set of the target cable, the method further includes: using a preset standard mapping table to convert the cable data set into a standardized cable data set.

[0067] Correspondingly, for each cable parameter, calculate the similarity value between the parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter, including: for each cable parameter, calculate the similarity value between the standardized parameter value of the cable parameter and the preset parameter value corresponding to the cable parameter. Construct a three-dimensional model of the target cable according to the remaining life and the cable data set, including: construct a three-dimensional model of the target cable according to the remaining life and the standardized cable data set.

[0068] Optionally, the preset standard mapping table is a preset standard conversion table for each cable parameter, so as to unify the units or the valid data bits of the unified cable parameters in different regions, that is, to standardize the cable data. For example, the cable parameter may include the cable working years, and there may be different forms such as "XX years XX months XX days", "XX.XX.XX", "XX years", etc. The preset standard mapping table converts the above three forms into the form of "XXXXXX", removing Chinese characters and decimal points, and using "0" to replace the non-existent bits.

[0069] Exemplarily, the preset standard mapping table can convert "January 1, 22 years" into "220101", convert "22.1.2" into "220102", and convert "22 years" into "220000". The same applies to other cable parameters. Each cable parameter can be converted into the standard form corresponding to the cable parameter through the preset standard mapping table.

[0070] In the embodiment of the present invention, by adding the remaining life of the cable to the three-dimensional model corresponding to the cable, timely maintenance can be carried out, and the reliability of the underground cable work can be improved. At the same time, standardizing the cable parameters and then standardizing the three-dimensional cable model can improve the modeling efficiency.

[0071] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
