In cable applications, the importance of environmental factors cannot be ignored. A proper operating environment can better protect cables and improve their life and reliability.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. 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.

[0047] A cable parameter monitoring method based on oxygen concentration changes provided in an embodiment of the present application can be applied to cable parameter monitoring scenarios. A cable parameter monitoring method based on oxygen concentration changes provided in an 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 embodiments of the present application.

[0048] Figure 1 A flow chart of a cable parameter monitoring method based on oxygen concentration change provided by an embodiment of the present invention, such as Figure 1 As shown, specifically including:

[0049] Step S101: Obtain a first oxygen concentration value reported at a current cable location point, and determine a sample collection period at the cable location point according to the first oxygen concentration value and a preset period determination rule.

[0050] Among them, the cable location point can be a location point on the cable divided according to the set division rule. The cable location point can be equipped with various environmental parameters and cable parameter collection equipment. The first oxygen concentration value is used to characterize the value of the oxygen concentration around the current cable location point. The preset cycle determination rule is used to characterize the method of pre-set sample collection cycle for determining the cable location point. The sample collection cycle can be the interval time for collecting sample data once. In one embodiment, after obtaining the reported first oxygen concentration value of the current cable location point, the preset cycle comparison table is queried according to the first oxygen concentration value to obtain the corresponding collection cycle, and it is determined as the sample collection cycle of the cable location point. Optionally, a method for determining the sample collection cycle can be to determine the preset oxygen concentration interval into which the first oxygen concentration value falls, and determine the preset cycle associated with the preset oxygen concentration interval as the sample collection cycle of the cable location point, wherein the higher or lower the oxygen concentration value, the shorter the corresponding sample collection cycle. Determining the collection cycle of sample data by the size of the oxygen concentration around the cable can improve the rationality of the collection cycle and the efficiency of data monitoring.

[0051] Step S102: collecting first collected data and oxygen concentration data of a plurality of oxygen influencing parameters of the cable position points according to the sample collection cycle and the preset cycle collection quantity, and determining an updated collection cycle based on the plurality of first collected data and the oxygen concentration data.

[0052] Among them, the preset cycle collection number is used to characterize the number of sample collection cycles for executing sample collection that is preset. The oxygen influencing parameter may be a cable parameter affected by oxygen concentration, such as a cable skin breakage parameter, an insulation performance parameter, and other cable parameters. The first collection data may be the numerical data of the oxygen influencing parameter collected. The oxygen concentration data may be the numerical data of the oxygen concentration collected. Exemplarily, the oxygen influencing parameter is an insulation performance parameter and a cable skin breakage parameter, the sample collection cycle is 30 minutes, and the preset cycle collection number is 5. Then, the insulation performance parameter, the cable skin breakage parameter, and the oxygen concentration value are collected every 30 minutes, and the sample collection is performed 5 times. After the sample collection is completed, the first collection data of the insulation performance parameter is 60MΩ, 59MΩ, 57MΩ, 55MΩ, and 53MΩ. The first collection data of the cable skin breakage parameter is 3%, 5%, 8%, 12%, and 15%, and the oxygen concentration data is 24%, 25%, 26%, 28%, and 30%. The updated collection cycle is used to characterize the new collection cycle that replaces the sample collection cycle. In one embodiment, after collecting the first collection data of multiple oxygen influencing parameters and oxygen concentration data, the sample collection period, multiple first collection data and oxygen concentration data are input into the trained period update model to obtain an updated collection period. Optionally, the first collection data includes multiple oxygen influencing parameter values ​​corresponding to the oxygen influencing parameters, and the oxygen concentration data includes multiple oxygen concentration values. A method for determining the updated collection period may be to calculate the corresponding numerical change rate according to the multiple oxygen influencing parameter values ​​of each oxygen influencing parameter, and calculate the oxygen concentration change rate according to the multiple oxygen concentration values ​​in the oxygen concentration data, and determine the updated collection period based on the numerical change rate of each oxygen influencing parameter and the oxygen concentration change rate. By calculating the change rate of each oxygen influencing parameter and the oxygen concentration to determine the updated collection period, the collection period during cable monitoring can be made more reasonable, and the accuracy and efficiency of cable monitoring can be improved.

[0053] Step S103, collecting parameter values ​​of a plurality of the oxygen influencing parameters and a second oxygen concentration value at the cable location point according to the update collection period, and determining a monitoring result of the cable location point based on the parameter values ​​of the plurality of the oxygen influencing parameters and the second oxygen concentration value.

[0054] Among them, the second oxygen concentration value is used to characterize the oxygen concentration value of the cable location point collected during the update collection period. In one embodiment, after the parameter values ​​of multiple oxygen-affecting parameters and the second oxygen concentration value of the cable location point are collected during the update collection period, it is determined whether the parameter value of each oxygen-affecting parameter is within the corresponding preset standard interval. If not, the corresponding oxygen-affecting parameter is determined as an abnormal parameter, and a comparison process is performed based on the second oxygen concentration value and the parameter value of the abnormal parameter, and the monitoring result of the cable location point is determined according to the comparison process result. Optionally, a method for determining the monitoring result of a cable location point may be to compare the parameter values ​​of multiple oxygen-affecting parameters with the corresponding standard comparison values ​​respectively, and when the comparison result meets the abnormal condition associated with the corresponding oxygen-affecting parameter, the corresponding oxygen-affecting parameter is determined as an abnormal parameter, and the monitoring result of the cable location point is determined based on the second oxygen concentration value and the parameter value of the abnormal parameter. By comparing the parameter value of the oxygen-affecting parameter with the normal value to obtain the abnormal parameter, and then determining the monitoring result of the cable location point based on the oxygen concentration and the abnormal parameter, the cable parameters can be reasonably monitored in combination with the oxygen concentration, thereby improving the cable monitoring efficiency.

[0055] From the above, it can be known that the first oxygen concentration value reported at the current cable location point is obtained, the sample collection period of the cable location point is determined according to the first oxygen concentration value of the current cable location point and the preset period determination rule, the first collection data and oxygen concentration data of multiple oxygen influencing parameters of the cable location point are collected according to the sample collection period and the preset period collection quantity, the update collection period is determined based on the multiple first collection data and oxygen concentration data, the parameter values ​​of multiple oxygen influencing parameters and the second oxygen concentration value of the cable location point are collected according to the update collection period, and the monitoring result of the cable location point is determined based on the parameter values ​​of multiple oxygen influencing parameters and the second oxygen concentration value. This solution solves the problem of the lack of a reasonable monitoring mechanism for cables in combination with oxygen concentration in the related art, and can reasonably monitor the cables by collecting and analyzing the oxygen concentration, thereby improving the cable monitoring efficiency.

[0056] Figure 2 A flowchart of another cable parameter monitoring method based on oxygen concentration change provided by an embodiment of the present invention provides an optional specific method for determining the update collection cycle, such as Figure 2 As shown, specifically including:

[0057] Step S201: Obtain a first oxygen concentration value reported at a current cable location point, and determine a sample collection period at the cable location point according to the first oxygen concentration value and a preset period determination rule.

[0058] Step S202: collecting first collected data of a plurality of oxygen influencing parameters and oxygen concentration data of the cable position points according to the sample collection cycle and the preset cycle collection quantity.

[0059] Step S203, respectively calculating the corresponding numerical change rate according to the multiple oxygen influencing parameter values ​​of each of the oxygen influencing parameters, and calculating the oxygen concentration change rate according to the multiple oxygen concentration values ​​in the oxygen concentration data, and determining the update collection period based on the numerical change rate of each of the oxygen influencing parameters and the oxygen concentration change rate.

[0060] Among them, the first acquisition data includes a plurality of oxygen influence parameter values ​​corresponding to the oxygen influence parameter, and the oxygen concentration data includes a plurality of oxygen concentration values. The value change rate is used to characterize the change rate of the value of the oxygen influence parameter in the first acquisition data. The oxygen concentration change rate is used to characterize the change rate of the oxygen concentration value in the oxygen concentration data. In one embodiment, after calculating the value change rate of each oxygen influence parameter and the oxygen concentration change rate, the difference between the value change rate of each oxygen influence parameter and the oxygen concentration change rate and the corresponding preset standard value is calculated respectively, and the corresponding preset period adjustment value comparison table is queried according to each difference to obtain the corresponding period adjustment value, the period adjustment value includes positive value and negative value, and the sample acquisition period is adjusted based on each period adjustment value to obtain the updated acquisition period. Optionally, a method for determining the updated acquisition period may be to obtain the preset weights of each oxygen influence parameter and oxygen concentration, multiply each period adjustment value by the corresponding preset weight respectively and superimpose to obtain the final period adjustment value, and superimpose the sample acquisition period and the final period adjustment value to obtain the updated acquisition period. An exemplary example may be that the oxygen influencing parameters are the cable skin breakage parameters and the insulation performance parameters. The cable skin breakage parameter value change rate is calculated to be 9% / h according to the multiple cable skin breakage parameter values ​​in the first collected data corresponding to the cable skin breakage parameter. The insulation performance parameter value change rate is calculated to be 8MΩ / h according to the multiple insulation performance parameter values ​​in the first collected data corresponding to the insulation performance parameter. The oxygen concentration change rate is calculated to be 11% / h according to the multiple oxygen concentration values ​​in the oxygen concentration data. The preset standard values ​​corresponding to the cable skin breakage parameter, the insulation performance parameter and the oxygen concentration are 3% / h, 4MΩ / h and 5% / h, respectively, and the differences from the corresponding preset standard values ​​are 6% / h, 4MΩ / h and 6% / h, respectively. The preset period adjustment value comparison table corresponding to the cable skin breakage parameter is shown in the following table:

[0061]

[0062]

[0063] The above comparison table describes the comparison relationship between the difference between the change rate of the cable skin breakage parameter value and the preset standard value and the period adjustment value, which is specifically described as follows: when the difference is (0, 3% / h], the period adjustment value corresponding to the cable skin breakage parameter is -10min; when the difference is (3% / h, 6% / h], the period adjustment value corresponding to the cable skin breakage parameter is -20min; when the difference is (6% / h, 9% / h], the period adjustment value corresponding to the cable skin breakage parameter is -30min; when the difference is (-3% / h, 0], the period adjustment value corresponding to the cable skin breakage parameter is +15min.

[0064] According to the difference of 6% / h, the period adjustment value corresponding to the cable skin breakage parameter is -20min. In the same way, the period adjustment values ​​corresponding to the insulation performance parameter and oxygen concentration are -10min and -15min respectively. The sample collection period is 30min. The preset weights corresponding to the cable skin breakage parameter, insulation performance parameter and oxygen concentration are 0.3, 0.5 and 0.2 respectively. The calculated update collection period is 16min (30-((-20)*0.3+(-10)*0.5+(-15)*0.2)).

[0065] In another embodiment, after calculating the numerical change rate of each oxygen influencing parameter and the change rate of oxygen concentration, the numerical change rate of each oxygen influencing parameter and the change rate of oxygen concentration are input into a preset period adjustment value calculation formula to obtain a period adjustment value, and the sample collection period is adjusted according to the period adjustment value to obtain an updated collection period, wherein the preset period adjustment value can be (oxygen influencing parameter change rate 1*conversion coefficient a+oxygen influencing parameter change rate 2*conversion coefficient b+oxygen concentration change rate 2*conversion coefficient)*preset period value.

[0066] Step S204: collecting parameter values ​​of a plurality of the oxygen influencing parameters and a second oxygen concentration value at the cable location point according to the update collection period, and determining a monitoring result of the cable location point based on the parameter values ​​of the plurality of the oxygen influencing parameters and the second oxygen concentration value.

[0067] As can be seen from the above, the corresponding numerical change rates are calculated according to the multiple oxygen influence parameter values ​​of each oxygen influence parameter, and the oxygen concentration change rate is calculated according to the multiple oxygen concentration values ​​in the oxygen concentration data, and the updated collection period is determined based on the numerical change rate of each oxygen influence parameter and the oxygen concentration change rate. This solution can make the collection period during cable monitoring more reasonable and improve the accuracy and efficiency of cable monitoring by calculating the change rate of each oxygen influence parameter and the oxygen concentration to determine the updated collection period.

[0068] Figure 3A flowchart of another cable parameter monitoring method based on oxygen concentration change provided by an embodiment of the present invention provides an optional specific method for determining the monitoring result, such as Figure 3 As shown, specifically including:

[0069] Step S301: Obtain a first oxygen concentration value reported at a current cable location point, and determine a sample collection period at the cable location point according to the first oxygen concentration value and a preset period determination rule.

[0070] Step S302: collecting first collected data and oxygen concentration data of a plurality of oxygen influencing parameters of the cable position points according to the sample collection cycle and the preset cycle collection quantity, and determining an updated collection cycle based on the plurality of first collected data and the oxygen concentration data.

[0071] Step S303: collecting parameter values ​​of a plurality of oxygen influencing parameters and a second oxygen concentration value at the cable location point according to the update collection cycle.

[0072] Step S304: compare the parameter values ​​of the plurality of oxygen influencing parameters with the corresponding standard comparison values ​​respectively; when the comparison result satisfies the abnormal condition associated with the corresponding oxygen influencing parameter, determine the corresponding oxygen influencing parameter as an abnormal parameter; and determine the monitoring result of the cable location point based on the second oxygen concentration value and the parameter value of the abnormal parameter.

[0073] Among them, the standard comparison value can be a standard specification value of the oxygen influencing parameter, or it can be a standard value set according to actual conditions. Abnormal conditions are used to characterize the pre-set conditions for judging whether the oxygen influencing parameters are abnormal. Abnormal parameters are used to characterize abnormal oxygen influencing parameters. Optionally, a method for determining a monitoring result can be to determine a preset oxygen concentration interval associated with the parameter value of the abnormal parameter, and determine whether the second oxygen concentration value is within the preset oxygen concentration interval. The preset oxygen concentration interval corresponds to an associated attribute, and the associated attribute includes a high oxygen concentration attribute and a low oxygen concentration attribute. If the second oxygen concentration value is within the preset oxygen concentration interval, the associated attribute corresponding to the preset oxygen concentration interval and the abnormal parameter are substituted into the first preset template to generate a monitoring result. If the second oxygen concentration value is not within the preset oxygen concentration interval, the content of the second preset template is determined as the monitoring result, wherein the content of the second preset template can be that there is no abnormality in oxygen concentration, and the cable parameter abnormality is not related to oxygen concentration. An exemplary example may be that the cable skin breakage parameter value is 40%, the insulation performance parameter value is 43 megohms, the standard comparison value of the cable skin breakage parameter is 30%, the standard comparison value of the insulation performance parameter is 40 megohms, the cable skin breakage parameter value is greater than the corresponding standard comparison value, the insulation performance parameter value is greater than the corresponding standard comparison value, the abnormal condition associated with the cable skin breakage parameter is that the cable skin breakage parameter value is greater than the corresponding standard comparison value, the abnormal condition associated with the insulation performance parameter is that the insulation performance parameter value is less than the corresponding standard comparison value, that is, the comparison result of the cable skin breakage parameter value meets the corresponding abnormal condition, and the cable skin breakage parameter is an abnormal parameter. , the cable skin breakage parameter value is 40%, and the associated preset oxygen concentration intervals are [15%, 18%) and (23%, 25%). The associated attribute of [15%, 18%) is the low oxygen concentration attribute, and the associated attribute of (23%, 25%) is the high oxygen concentration attribute. The second oxygen concentration value is 16%, which is within the interval [15%, 18%). The first preset template is *** abnormality caused by xxx. The associated attribute of the preset oxygen concentration interval that the second oxygen concentration value falls into is filled in "xxx", and the abnormal parameter is filled in "***", that is, the monitoring result is that the cable skin breakage parameter is abnormal due to high oxygen concentration.

[0074] In another embodiment, after determining the abnormal parameter, it is determined whether the second oxygen concentration value is greater than the first preset value or less than the second preset value. If the second oxygen concentration value is greater than the first preset value or less than the second preset value, it is determined that there is an abnormal correlation between the abnormal parameter and the oxygen concentration, and the abnormal correlation is determined as the monitoring result.

[0075] As can be seen from the above, the parameter values ​​of multiple oxygen-affecting parameters are compared with the corresponding standard comparison values ​​respectively. When the comparison result satisfies the abnormal condition associated with the corresponding oxygen-affecting parameter, the corresponding oxygen-affecting parameter is determined as an abnormal parameter, and the monitoring result of the cable location point is determined based on the second oxygen concentration value and the parameter value of the abnormal parameter. This solution compares the parameter value of the oxygen-affecting parameter with the normal value to obtain the abnormal parameter, and then determines the monitoring result of the cable location point based on the oxygen concentration and the abnormal parameter. It can reasonably monitor the cable parameters in combination with the oxygen concentration, thereby improving the cable monitoring efficiency.

[0076] Figure 4 A flowchart of another cable parameter monitoring method based on oxygen concentration change provided by an embodiment of the present invention provides an optional specific method for determining the sample collection period, such as Figure 4 As shown, specifically including:

[0077] Step S401, obtain the first oxygen concentration value reported for the current cable location point, determine the preset oxygen concentration interval within which the first oxygen concentration value falls, and determine the preset period associated with the preset oxygen concentration interval as the sample collection period of the cable location point, wherein the higher or lower the oxygen concentration value, the shorter the corresponding sample collection period.

[0078] Among them, the preset oxygen concentration interval can be a numerical interval of each preset oxygen concentration value. The preset oxygen concentration interval can be associated with a preset period. The preset period can be a data collection period under the corresponding oxygen concentration that is preset. An exemplary example can be that the preset oxygen concentration interval 1 is [18%, 19%), the preset oxygen concentration interval 2 is [20%, 22%], and the preset oxygen concentration interval 3 is (22%, 23%], and the preset periods associated with the preset oxygen concentration intervals 1, 2, and 3 are 20 minutes, 30 minutes, and 20 minutes respectively. The first oxygen concentration value of the current cable position point reported is 18.5%, and the interval it falls into is the preset oxygen concentration interval 1, and the corresponding preset period is 20 minutes, that is, the sample collection period of the cable position point is determined to be 20 minutes.

[0079] Step S402: collecting first collected data and oxygen concentration data of a plurality of oxygen influencing parameters of the cable position points according to the sample collection cycle and the preset cycle collection quantity, and determining an updated collection cycle based on the plurality of first collected data and the oxygen concentration data.

[0080] Step S403: collecting parameter values ​​of a plurality of the oxygen influencing parameters and a second oxygen concentration value at the cable location point according to the update collection period, and determining a monitoring result of the cable location point based on the parameter values ​​of the plurality of the oxygen influencing parameters and the second oxygen concentration value.
