In addition, "and or or" in the specification and claims represents at least one of the connected objects, and the character "or" generally indicates that the objects associated before and after are in an "or" relationship.

[0041] The cable aging assessment method based on operating conditions and environmental conditions provided in the embodiment of the present application can be applied to cable aging assessment scenarios. For example, in the case of aging assessment of buried cables, the aging assessment of buried cables can be performed using the aging assessment method provided in the embodiment of the present application. The cable aging assessment method based on operating conditions and environmental conditions provided in the embodiment of the present application, the execution subject of each step can be a computer device, which refers to any electronic device with data calculation, processing and storage capabilities, such as mobile phones, PCs (Personal Computers), tablet computers and other terminal devices, and can also be servers and other devices, which are not limited in the embodiment of the present application.

[0042] Figure 1 A flowchart of a cable aging assessment method based on operating conditions and environmental conditions is provided in an embodiment of the present invention, such as Figure 1 As shown, specifically including:

[0043] Step S101: obtaining the current usage time, aging operation impact parameter information, pre-stored standard information and environmental information of the cable to be evaluated.

[0044] Among them, the cable to be evaluated is used to characterize the cable waiting for aging evaluation, the service life is used to characterize the length of time from the installation completion and commissioning of the cable to be evaluated to the current time, the aging operation impact parameter information is used to characterize the collected relevant information of the cable operation parameters affected by the cable aging, the pre-stored standard information is used to characterize the pre-stored information of the aging operation impact parameter of the cable to be evaluated when it has not aged, and the environmental information is used to characterize the data information of the surrounding environment where the cable to be evaluated is installed. An exemplary example can be that the current service life of the cable to be evaluated is 5 years, the aging operation impact parameter information is a voltage value of 200V, a resistance value of 11MΩ / km, and an energy loss value of 4%, the pre-stored standard information is a standard voltage value of 220V, a standard resistance value of 10MΩ / km, a standard energy loss value of 3%, and the environmental information is an ambient temperature of 25°C and an ambient humidity of 20%. Obtaining the current service life of the cable to be evaluated, the aging operation impact parameter information, the pre-stored standard information, and the environmental information can improve the reference dimension and rationality of the cable aging evaluation.

[0045] Step S102: Acquire aging detection information stored corresponding to the environmental information, and determine a first aging evaluation value of the cable to be evaluated according to the usage time and the aging detection information.

[0046] Among them, the aging detection information is used to characterize the detected information of the aging condition of the cable to be evaluated under the environmental information, and the first aging evaluation value is used to characterize the evaluation value of the aging of the cable to be evaluated according to the environmental information. In one embodiment, the aging detection information corresponding to the environmental information of the cable to be evaluated is obtained, and the detection evaluation value corresponding to the use time of the cable to be evaluated in the aging detection information is queried, and the detection evaluation value obtained by the query is determined as the first aging evaluation value of the cable to be evaluated. Optionally, the aging detection information includes a plurality of detection aging degrees corresponding to sample durations. A method for determining the first aging evaluation value may be: when the sample duration is the same as the use duration, the detection aging degree corresponding to the sample duration that is the same as the use duration is determined as the first aging evaluation value of the cable to be evaluated. When the sample duration is not the same as the use duration, the first aging evaluation value of the cable to be evaluated is calculated according to the use duration, the sample duration and the corresponding detection aging degree. Through the stored conventional detection data, the influence of the environmental information on the current aging of the cable can be reasonably evaluated.

[0047] Step S103: determining a second aging evaluation value of the cable to be evaluated based on the aging operation influencing parameter information and the pre-stored standard information.

[0048] Among them, the second aging evaluation value is used to characterize the evaluation value of the aging of the cable to be evaluated based on the aging operation influencing parameter information. In one embodiment, the aging operation influencing parameter information is compared with the pre-stored standard information, and the second aging evaluation value of the cable to be evaluated is determined according to the comparison result. Optionally, the aging operation influencing parameter information includes multiple aging operation influencing parameters and corresponding aging operation influencing parameter values, the pre-stored standard information includes multiple standard values ​​corresponding to the aging operation influencing parameters, and the aging operation influencing parameters are used to characterize the cable operation parameters affected by cable aging. A method for determining the second aging evaluation value may be: calculating the difference between each aging operation influencing parameter value and the corresponding standard value of the aging operation influencing parameter, and calculating the second aging evaluation value of the cable to be evaluated based on the difference corresponding to each aging operation influencing parameter, so as to reasonably evaluate the cable aging condition through various operation parameter data of the cable.

[0049] Step S104: obtaining a first preset weight of the first aging assessment value and a second preset weight of the second aging information, and calculating the final aging assessment value of the cable to be evaluated according to the first preset weight, the second preset weight, the first aging assessment value, and the second aging assessment value.

[0050] Among them, the first preset weight is used to characterize the importance of the first aging assessment value, the second preset weight is used to characterize the importance of the second aging assessment value, and the final aging assessment value is used to characterize the current aging condition of the cable to be evaluated. In one embodiment, after determining the first aging assessment value and the second aging assessment value, the first preset weight of the first aging assessment value and the second preset weight of the second aging information are obtained, and the first preset weight and the second preset weight are respectively multiplied with the corresponding first aging assessment value and the second aging assessment value and superimposed to obtain the final aging assessment value of the cable to be evaluated. An exemplary example can be that the first aging assessment value is 30%, the second aging assessment value is 45%, the first preset weight is 0.3, and the second preset weight is 0.7, then the final aging assessment value of the cable to be evaluated is calculated to be 40.5% (30%*0.3+45%*0.7). In another embodiment, the first preset weight and the second preset weight are respectively multiplied with the corresponding first aging assessment value and the second aging assessment value to obtain the first weight assessment value and the second weight assessment value, and the first weight assessment value and the second weight assessment value are substituted into the preset calculation formula to obtain the final aging assessment value. The actual aging condition of the cable can be determined by evaluating the aging of the cable through environmental information and operating parameter information, which can make reasonable aging evaluation of cables that are difficult to detect manually or take images, thereby improving the adaptability of cable aging evaluation.

[0051] From the above, it can be known that the current usage time, aging operation influencing parameter information, pre-stored standard information and environmental information of the cable to be evaluated are obtained, the aging detection information stored corresponding to the environmental information is obtained, the first aging evaluation value of the cable to be evaluated is determined according to the usage time and aging detection information, the second aging evaluation value of the cable to be evaluated is determined based on the aging operation influencing parameter information and the pre-stored standard information, the first preset weight of the first aging evaluation value and the second preset weight of the second aging information are obtained, and the final aging evaluation value of the cable to be evaluated is calculated according to the first preset weight and the second preset weight and the first aging evaluation value and the second aging evaluation value. This scheme evaluates the aging of the cable through operating conditions and environmental conditions, solves the problem that the existing cable aging evaluation technology is limited in applicable scenarios and is not suitable for large-scale automated cable aging evaluation, and can perform reasonable aging evaluation on cables that are not easy to manually detect or take images, thereby improving the adaptability range of cable aging evaluation.

[0052] Figure 2 A flowchart of another cable aging assessment method based on operating conditions and environmental conditions provided by an embodiment of the present invention provides an optional specific process for determining a first aging assessment value, such as Figure 2 As shown, specifically including:

[0053] Step S201: obtaining the current service life, aging operation influencing parameter information, pre-stored standard information and environmental information of the cable to be evaluated.

[0054] Step S202, obtaining aging detection information stored corresponding to the environmental information, and in the case where the sample duration is the same as the usage duration, determining the detected aging degree corresponding to the sample duration that is the same as the usage duration as the first aging evaluation value of the cable to be evaluated.

[0055] The aging detection information includes the detection aging degrees corresponding to multiple sample durations, the sample duration may be the time length set when performing the detection, the detection aging degree may be the aging degree of the cable with the same specification as the cable to be evaluated detected under the environmental information of the cable to be evaluated, and a method for determining the first aging evaluation value may be: when there is a sample duration that is the same as the usage duration of the cable to be evaluated, the detection aging degree corresponding to the sample duration that is the same as the usage duration is determined as the first aging evaluation value of the cable to be evaluated. An exemplary example may be that the sample durations include 1 year, 2 years, 3 years, 4 years, and 5 years, and the corresponding detection aging degrees are 2%, 4%, 6%, 12%, and 15%, and the usage duration of the cable to be evaluated is 4 years.

[0056] Step S203: When there is no case where the sample duration is the same as the usage duration, a first aging evaluation value of the cable to be evaluated is calculated according to the usage duration, the sample duration and the corresponding detection aging degree.

[0057] Wherein, in the case that there is no sample duration that is the same as the usage duration of the cable to be evaluated, optionally, a method for determining the first aging evaluation value may be: determining the aging degree per unit time of the cable to be evaluated under the environmental information based on the sample duration and the corresponding detected aging degree, and multiplying the usage duration of the cable to be evaluated by the aging degree per unit time to obtain the first aging evaluation value of the cable to be evaluated. Optionally, a method for determining the aging degree per unit time may be: dividing each detected aging degree by the corresponding sample duration to obtain multiple unit aging degrees to be adjusted, calculating the average value of the unit aging degrees to be adjusted and determining it as the aging degree per unit time of the cable to be evaluated under the environmental information. An exemplary example may be that the service life of the cable to be evaluated is 10 years, and the sample durations include 1 year, 2 years, 3 years, 4 years, and 5 years, and the corresponding detection aging degrees are 2%, 4%, 6%, 12%, and 15%. The unit aging degrees to be adjusted corresponding to each sample duration are calculated to be 2%, 2%, 2%, 3%, and 3% respectively. The average value of the unit aging degree to be adjusted is calculated, that is, the aging degree of the cable to be evaluated per unit time under the environmental information is 2.4%. The service life of the cable to be evaluated is multiplied by the aging degree per unit time to obtain a first aging evaluation value of the cable to be evaluated of 24%. In another embodiment, the aging detection information includes a unit aging degree per preset unit time, and the service life of the cable to be evaluated is converted according to the preset unit time, and the converted service life is multiplied by the unit aging degree to obtain the first aging evaluation value of the cable to be evaluated.

[0058] Step S204: determining a second aging evaluation value of the cable to be evaluated based on the aging operation influencing parameter information and the pre-stored standard information.

[0059] Step S205: Obtain a first preset weight of the first aging assessment value and a second preset weight of the second aging information, and calculate the final aging assessment value of the cable to be evaluated according to the first preset weight, the second preset weight, the first aging assessment value, and the second aging assessment value.

[0060] From the above, it can be seen that when there is a sample duration that is the same as the usage duration of the cable to be evaluated, the detection aging degree corresponding to the sample duration that is the same as the usage duration is determined as the first aging evaluation value of the cable to be evaluated. When there is no sample duration that is the same as the usage duration of the cable to be evaluated, the first aging evaluation value of the cable to be evaluated is calculated based on the usage duration, the sample duration and the corresponding detection aging degree. This solution can reasonably evaluate the impact of environmental information on the current aging of the cable through conventional detection data.

[0061] Figure 3 A flowchart of another cable aging evaluation method based on operating conditions and environmental conditions provided by an embodiment of the present invention provides an optional specific process for determining a second aging evaluation value, such as Figure 3 As shown, specifically including:

[0062] Step S301: obtaining the current service life, aging operation impact parameter information, pre-stored standard information and environmental information of the cable to be evaluated.

[0063] Step S302: Acquire aging detection information stored corresponding to the environmental information, and determine a first aging evaluation value of the cable to be evaluated according to the usage time and the aging detection information.

[0064] Step S303: Calculate the difference between each aging operation influencing parameter value and the corresponding standard value of the aging operation influencing parameter, and calculate the second aging assessment value of the cable to be assessed based on the difference corresponding to each aging operation influencing parameter.

[0065] Among them, the aging operation influencing parameter information includes multiple aging operation influencing parameters and corresponding aging operation influencing parameter values, the pre-stored standard information includes multiple standard values ​​corresponding to the aging operation influencing parameters, and a method for determining the second aging evaluation value may be: calculating the difference between each aging operation influencing parameter value and the corresponding standard value of the aging operation influencing parameter, and calculating the second aging evaluation value of the cable to be evaluated based on the difference corresponding to each aging operation influencing parameter. Optionally, according to the difference, the preset deduction life mapping table of the corresponding aging operation influencing parameter is queried to obtain the corresponding deduction life, the service life of the cable to be evaluated is obtained, and the second aging evaluation value of the cable to be evaluated is calculated based on the deduction life and the service life. Optionally, a calculation method may be: superimposing the deduction life corresponding to each aging operation influencing parameter to obtain the total deduction life, calculating the ratio of the total deduction life to the service life and determining it as the second aging evaluation value of the cable to be evaluated. An exemplary example may be that the aging operation influencing parameter information includes a voltage parameter and a voltage parameter value of 180v, a resistance parameter and a resistance parameter value of 15MΩ / km, an energy loss parameter and an energy loss parameter value of 5%, a voltage parameter standard value of 220v, a resistance parameter standard value of 10MΩ / km, an energy loss parameter standard value of 3%, a difference between the voltage parameter value and the voltage parameter standard value of 40v, a difference between the resistance parameter value and the resistance parameter standard value of 5MΩ / km, a difference between the energy loss parameter value and the energy loss parameter standard value of 2%, and a preset deduction life mapping table corresponding to the voltage parameter, as shown in the following table:

[0066] Voltage difference Deduct life (0，20] 2 years (20，40] 4 years (40，60] 8 years (60，80] 10 years

[0067] The above mapping table represents the relationship between the difference corresponding to the voltage parameter and the deducted life, which is specifically described as follows: when the difference corresponding to the voltage falls within (0, 20], the deducted life is 2 years; when the difference corresponding to the voltage falls within (20, 40], the deducted life is 4 years; when the difference corresponding to the voltage falls within (40, 60], the deducted life is 8 years; when the difference corresponding to the voltage falls within (60, 80], the deducted life is 10 years.

[0068] The difference corresponding to the current voltage parameter value is 40v, then the preset deduction life mapping table is queried to obtain a deduction life of 4 years. In the same way, the preset deduction life mapping tables corresponding to the resistance parameter and the energy loss parameter are queried to obtain deduction lives of 4 years and 2 years respectively, then the total deduction life is 10 years, the service life of the cable to be evaluated is 25 years, and the ratio of the total deduction life to the service life is calculated to be 40%, that is, the second aging evaluation value of the cable to be evaluated is 40%. In another embodiment, the difference between each aging operation influencing parameter value and the standard value of the corresponding aging operation influencing parameter is calculated, and the preset variation interval of the corresponding aging operation influencing parameter that the difference falls into is determined, and the preset aging evaluation value corresponding to the preset variation interval is determined as the aging evaluation value to be calculated of the aging operation influencing parameter, and the aging evaluation value to be calculated is multiplied by the preset parameter weight of the corresponding aging operation influencing parameter and superimposed to obtain the second aging evaluation value of the cable to be evaluated.

[0069] Step S304: obtain a first preset weight of the first aging assessment value and a second preset weight of the second aging information, and calculate the final aging assessment value of the cable to be evaluated according to the first preset weight, the second preset weight, the first aging assessment value, and the second aging assessment value.

[0070] As can be seen from the above, after determining the first aging evaluation value, the difference between each aging operation influencing parameter value and the corresponding standard value of the aging operation influencing parameter is calculated, and the second aging evaluation value of the cable to be evaluated is calculated based on the difference corresponding to each aging operation influencing parameter. This solution can reasonably evaluate the aging of the cable through the comparison results of various operation parameter data of the cable with the corresponding standard data.

Figure 4 As shown, the system specifically includes:
