[0037] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may 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 prevent unnecessary details from obstructing the description of the present invention.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0039] See also Figure 1 , which shows a flow chart of the implementation of the data updating method of the underground cable model provided by an embodiment of the present invention. Figure 1 As shown, a method for updating data of an underground cable model may include:

[0040] S101, obtaining a data value set of a target cable; the data value set includes data values ​​of power consumption data of the target cable at M moments.

[0041] Optionally, the target cable is a cable for which an underground cable model has been constructed. The data value set may include data values ​​of power consumption data of the target cable at M moments. The power consumption data may be voltage, current, or other data that can be updated in the underground cable model of the target cable, which may be specifically determined according to the underground cable model of the target cable.

[0042] S102, calculating the distance between the data value of the power consumption data at each moment and the first preset data value to obtain M first distance values; the first preset data value is determined according to the data value of the power consumption data when the target cable is in a normal state.

[0043] Optionally, the first preset data value may be a representative data value according to the power consumption data of the target cable in a normal state, for example, an average value. The first distance value may be calculated by a clustering method.

[0044] Specifically, for the electricity consumption data at each moment, the distance value between the data value of the electricity consumption data and the first preset data value is calculated and marked as the first distance value. The first distance value indicates the distance relationship between the electricity consumption data and the first preset data value, that is, the first distance value can be used to determine whether the electricity consumption data is normal.

[0045] S103, calculating the distance between the data value of the power consumption data at each moment and the second preset data value to obtain M second distance values; the second preset data value is determined according to the data value of the power consumption data when the target cable is in an abnormal state.

[0046] Optionally, the second preset data value may be a representative data value according to the power consumption data of the target cable in an abnormal state, for example, an average value. The second distance value may be calculated by the same clustering method as that for calculating the first distance value.

[0047] Specifically, for the electricity consumption data at each moment, the distance value between the data value of the electricity consumption data and the second preset data value is calculated and marked as the second distance value. The second distance value represents the distance relationship between the electricity consumption data and the second preset data value, that is, the second distance value can be used to determine whether the electricity consumption data is abnormal.

[0048] S104, judging whether the data value set is valid according to the M first distance values ​​and the M second distance values, and updating the underground cable model of the target cable with the data value set when the data value set is judged to be valid.

[0049] Optionally, the cable generally includes a normal state or an abnormal state, and the power usage data in the normal state and the power usage data in the abnormal state can be used to update the underground cable model to ensure that the model can reflect the status of the cable in real time.

[0050] When the power consumption data is neither the power consumption data under normal conditions nor the power consumption data under abnormal conditions, it indicates that the power consumption data is invalid, that is, the power consumption data cannot reflect the state of the underground cable model and needs to be eliminated to ensure the validity of the underground cable model.

[0051] Optionally, the validity of the data value set can be determined by the first distance value and the second distance value of each power consumption data. For example, if there is invalid power consumption data in the data value set, the data value set can be determined to be invalid, or if the number of invalid power consumption data in the data value set is greater than a certain number, the data value set can be determined to be invalid. The specific setting can be based on actual conditions.

[0052] When the data value set is determined to be valid, the data value set can be used to update the underground cable model. When the data value set is determined to be invalid, the power consumption data of the target cable can be re-collected to perform a determination update.

[0053] The embodiment of the present invention calculates the distance value between the data value of each power consumption data in the data value set and the first preset data value, and the distance value between the data value of each power consumption data and the second preset data value, and determines whether the data value set is valid according to the first distance value and the second distance value. Updating the corresponding underground cable model with a valid data value set can improve the accuracy and reliability of the underground cable model update. At the same time, the invalidity of the data value set can indicate to a certain extent that there is a problem with the acquisition equipment, and the problematic acquisition equipment can be repaired or replaced in time. Therefore, by judging whether the data value set is valid, the reliability of the acquisition equipment can also be improved.

[0054] In some embodiments of the present invention, the above-mentioned S104 of "determining whether the data value set is valid based on M first distance values ​​and M second distance values" may include: calculating the sum of the first distance value and the second distance value at the same time to obtain M distance sums; comparing the M distance sums with the preset distance sum to determine whether the data value set is valid.

[0055] Optionally, the sum of the first distance value and the second distance value at the same moment is calculated to obtain M distance sums. For each moment, the distance sum at that moment can indicate whether the power consumption data at that moment is valid. By judging whether the power consumption data at each moment is valid, it is further judged whether the data value set is valid.

[0056] Optionally, the preset distance sum can be set according to actual conditions, for example, it can be: the sum of the maximum distance value between the data value of normal power consumption data and the first preset data value and the maximum distance value between the data value of abnormal power consumption data and the second preset data value.

[0057] In some embodiments of the present invention, M distance sums are compared with a preset distance sum to determine whether the data value set is valid, including: comparing each distance sum with the preset distance sum, if the distance sum is greater than the preset distance sum, determining that the distance sum is invalid; if the distance sum is not greater than the preset distance sum, determining that the distance sum is valid; if the number of invalid distance sums is greater than the preset number, determining that the data value set is invalid; if the number of invalid distance sums is not greater than the preset number, determining that the data value set is valid.

[0058] Optionally, each distance sum is compared with a preset distance sum, and the power consumption data whose distance sum is greater than the preset distance sum is invalid data, which is neither normal power consumption data nor abnormal power consumption data, and cannot be used to update the underground cable model of the target cable. When invalid power consumption data is determined, the collection equipment for collecting power consumption data can be tested to determine whether there is a problem with the collection equipment, so as to facilitate timely maintenance or replacement to ensure the stability of the collection equipment.

[0059] The power consumption data whose distance sum is not greater than the preset distance sum is valid data. The power consumption data belongs to normal power consumption data or abnormal power consumption data, which truly reflects the status of the target cable and can be used to update the underground cable model of the target cable.

[0060] In some embodiments of the present invention, after comparing each distance sum with a preset distance sum, the method further comprises: if it is determined that the distance sum is invalid, issuing a first alarm signal.

[0061] Optionally, after determining that the distance and the data are invalid, a first alarm signal is issued to indicate that the distance and the corresponding power consumption data are invalid, and the power consumption data can be recorded to build an invalid power consumption database. Whether the power consumption data is invalid can also be determined through the invalid power consumption database.

[0062] In some embodiments of the present invention, the above-mentioned S102 of "calculating the distance value between the data value of the electricity consumption data at each moment and the first preset data value to obtain M first distance values" may include: using a clustering method, with the first preset data value as the cluster center, calculating the distance value between the data value of the electricity consumption data at each moment and the first preset data value to obtain M first distance values.

[0063] The above S103 "calculate the distance value between the data value of the electricity consumption data at each moment and the second preset data value to obtain M second distance values" may include: using a clustering method, taking the second preset data value as the cluster center, calculating the distance value between the data value of the electricity consumption data at each moment and the second preset data value to obtain M second distance values.

[0064] Optionally, a clustering method may be used to calculate the first distance value or the second distance value of the power consumption data at each moment with the first preset data value or the second preset data value as the cluster center, for example, a system clustering method or a k-means clustering method may be used.

[0065] In some embodiments of the present invention, after determining whether the data value set is valid according to the M first distance values ​​and the M second distance values, the method further comprises: issuing a second alarm signal when the data value set is determined to be invalid.

[0066] Optionally, when it is determined that the data value set is invalid, a second alarm signal may be issued to record the data value set to indicate that the data value set is invalid.

[0067] The embodiment of the present invention judges the data value set of the target cable and updates the underground cable model according to the valid data value set, thereby improving the reliability of the underground cable model data update, ensuring the authenticity of the underground cable data obtained through the model, improving the stability of the underground cable operation, and ensuring the stable operation of the power grid.

[0068] It should be understood that the order of execution of the steps in the above embodiment does not necessarily 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 embodiment of the present invention.

[0071] like Figure 2 As shown, the data updating device 20 for the underground cable model may include: an acquisition module 201 , a first calculation module 202 , a second calculation module 203 and a judgment module 204 .

[0072] The acquisition module 201 is used to acquire the data value set of the target cable; the data value set includes the data values ​​of the power consumption data of the target cable at M moments. The first calculation module 202 is used to calculate the distance value between the data value of the power consumption data at each moment and the first preset data value, and obtain M first distance values; the first preset data value is determined based on the data value of the power consumption data when the target cable is in a normal state. The second calculation module 203 is used to calculate the distance value between the data value of the power consumption data at each moment and the second preset data value, and obtain M second distance values; the second preset data value is determined based on the data value of the power consumption data when the target cable is in an abnormal state. The judgment module 204 is used to judge whether the data value set is valid based on the M first distance values ​​and the M second distance values, and when the data value set is judged to be valid, the underground cable model of the target cable is updated with the data value set.

[0073] In some embodiments of the present invention, the determination module 204 may include: a calculation unit and a determination unit.

[0074] The calculation unit is used to calculate the sum of the first distance value and the second distance value at the same time to obtain M distance sums. The judgment unit is used to compare the M distance sums with the preset distance sum to judge whether the data value set is valid.

[0075] In some embodiments of the present invention, the first judgment unit is also used to compare each distance sum with a preset distance sum. If the distance sum is greater than the preset distance sum, the distance sum is determined to be invalid; if the distance sum is not greater than the preset distance sum, the distance sum is determined to be valid; if the number of invalid distance sums is greater than the preset number, the data value set is determined to be invalid; if the number of invalid distance sums is not greater than the preset number, the data value set is determined to be valid.

[0078] In some embodiments of the present invention, the second calculation module 203 can also be used to use the clustering method, with the second preset data value as the cluster center, to calculate the distance value between the data value of the power consumption data at each moment and the second preset data value, and obtain M second distance values.
