[0038] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the embodiments of the present invention, rather than to limit the embodiments of the present invention. It is also necessary to explain that, for ease of description, only parts related to the embodiments of the present invention are shown in the accompanying drawings, rather than all structures.

[0039] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. 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.

[0040] The cable line foreign body type identification method based on multi-dimensional information provided in the embodiment of the present application can be applied to the cable foreign body coverage scenario. For example, when the presence of foreign bodies on the cable line is detected, the foreign body type identification method provided in the embodiment of the application can be used to identify the type of covered foreign bodies. In the cable line foreign body type identification method based on multi-dimensional information 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.

[0041] Figure 1 A flowchart of a method for identifying the type of foreign matter in a cable line based on multi-dimensional information provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, specifically including:

[0042] Step S101, obtaining a foreign object monitoring value monitored by a foreign object monitoring device of a current monitoring cable, and determining a value interval into which the foreign object monitoring value falls when the foreign object monitoring value meets a preset abnormal condition.

[0043] Among them, the monitoring cable can be a cable in a monitored state. The foreign matter monitoring device is a device used to characterize the relevant data of foreign matter on the monitoring cable line, and can be a pressure sensor or other equipment. The preset abnormal condition is used to characterize the pre-set condition for judging whether the foreign matter monitoring value is abnormal. In one embodiment, the foreign matter monitoring value monitored by the foreign matter monitoring device of the current monitoring cable is obtained, and the foreign matter monitoring value is compared with the preset abnormal value. When the foreign matter monitoring value is greater than or equal to the preset abnormal value, it is determined that the preset abnormal condition is met, and the foreign matter monitoring value is compared with multiple numerical intervals to determine the numerical interval containing the foreign matter monitoring value. An exemplary example may be that the foreign body monitoring device is a pressure sensor, and the pressure value collected by the pressure sensor of the current monitoring cable is 30 KPa / cm2, the preset abnormal pressure value is 20 KPa / cm2, the pressure value is greater than the preset abnormal pressure value, and the preset abnormal condition is met. The numerical interval includes interval 1 [20, 50] and interval 2 (50, 100], and the numerical interval in which the pressure value falls is interval 1 [20, 50]. Different types of foreign bodies exert different pressures on the cable. By determining the numerical interval in which the pressure value of the foreign body on the cable falls, the type of foreign body on the cable can be reasonably determined.

[0044] Step S102: Determine the type of monitoring cable associated with the foreign object monitoring device, and determine the associated reference information type according to the monitoring cable type and the numerical range.

[0045] Among them, the monitoring cable type can be used to characterize the installation type of the currently monitored cable, which can be a buried type and an overhead type. The reference information type is used to characterize the classification of information used to determine the type of foreign matter in the monitoring cable, which can be a weather type, a ground activity type, and the like. Optionally, after determining the numerical interval in which the foreign matter monitoring value falls, determine one or more reference information types associated with the numerical interval in which the foreign matter monitoring value falls. In the case where there are multiple reference information types, the reference information types that have an impact on the monitoring cable type are determined as the associated reference information types. By determining the classification of information used to determine the type of foreign matter in the monitoring cable based on the interval in which the monitoring cable type and the foreign matter monitoring value fall, the rationality of the reference information can be improved, thereby ensuring the accuracy of the determined foreign matter type. An exemplary example may be that the foreign object monitoring device is a pressure sensor 1, the monitoring cable type associated with the pressure sensor 1 is a buried type, the numerical interval in which the pressure value falls is interval a (50, 100], the reference information types associated with interval a include ground activity types and sky activity types, and the reference information type that has an influence relationship with the buried type is the ground activity type, that is, the associated reference information type is the ground activity type. In another embodiment, the monitoring cable type associated with the foreign object monitoring device is determined, and the preset reference information type mapping table is queried according to the monitoring cable type and the numerical interval to obtain the corresponding reference information type.

[0046] Step S103: obtaining reference information corresponding to the reference information type based on the monitoring cable type and a preset calling interface, wherein the reference information includes a plurality of reference parameters and corresponding reference parameter values.

[0047] Among them, the preset call interface is used to represent a tool for exchanging and transmitting information between two different systems through preset program codes and rules, the reference information is used to represent information used to determine the type of foreign matter in the monitoring cable, and the classification of reference parameters in the reference information belongs to the reference information type. In one embodiment, reference information corresponding to the monitoring cable type and the reference information type is obtained through the preset call interface, and the reference information includes multiple reference parameters and corresponding reference parameter values. Optionally, the reference parameters are determined according to the monitoring cable type and the reference information type, and the reference parameter values ​​of the reference parameters within a preset time are obtained based on the preset call interface, and the reference parameters and the reference parameter values ​​are determined as reference information. Obtaining reference information by calling the interface can reduce the cost of deploying hardware devices and save resources.

[0048] Step S104, determining a comparison value of the reference parameter according to the numerical range, performing comparison processing based on the reference parameter value and the comparison value of the corresponding reference parameter to obtain an abnormal reference parameter, and determining the type of foreign matter in the monitoring cable according to the abnormal reference parameter.

[0049] Among them, the abnormal reference parameter is used to characterize the reference parameter of the abnormal reference parameter value, and the foreign body type is used to characterize the classification of foreign bodies on the cable line. In one embodiment, the numerical interval into which the foreign body monitoring value falls corresponds to the comparison value of each reference parameter set in advance, and the abnormal reference parameter is obtained by comparison processing based on each reference parameter value and the comparison value of the corresponding reference parameter, and the foreign body type of the monitoring cable is determined according to the abnormal reference parameter. Optionally, a foreign body type determination method can be: determine the first associated foreign body type corresponding to the abnormal reference parameter as the foreign body type of the monitoring cable, and when there are multiple abnormal reference parameters, combine the abnormal reference parameters to obtain an abnormal reference parameter combination, and determine the second associated foreign body type corresponding to the abnormal reference parameter combination as the foreign body type of the monitoring cable. An exemplary example can be that the abnormal reference parameter obtained after the comparison processing is a snowfall parameter, and the corresponding first associated foreign body type is set as a dry snow type, that is, the foreign body type of the monitoring cable is a dry snow type. An exemplary example may also be that the abnormal reference parameters obtained after the comparison process are temperature parameters and rainfall parameters, the temperature parameters and rainfall parameters are combined into an abnormal reference parameter combination, and a comparison table of the preset abnormal reference parameter combination and the second associated foreign body type is shown in the following table:

[0050]

[0051] The above comparison table describes the association between the abnormal reference parameter combination and the second associated foreign object type, which is specifically described as follows: when the abnormal reference parameter combination is a temperature parameter and a rainfall parameter, the second associated foreign object type is a rime type; when the abnormal reference parameter combination is a humidity parameter and a snowfall parameter, the second associated foreign object type is a rime type; when the abnormal reference parameter combination is a temperature parameter and a humidity parameter, the second associated foreign object type is a frost type; when the abnormal reference parameter combination is a vehicle quantity parameter and a vehicle model parameter, the second associated foreign object type is a soil type. If the current abnormal reference parameter combination is a temperature parameter and a rainfall parameter, the corresponding second associated foreign object type is a rime type, that is, the foreign object type of the monitoring cable is a rime type. In another embodiment, the determined one or more abnormal reference parameters are input into a trained foreign object type analysis model to obtain the foreign object type of the monitoring cable.

[0052] From the above, it can be known that the foreign matter monitoring value detected by the foreign matter monitoring device of the current monitoring cable is obtained. When the foreign matter monitoring value meets the preset abnormal conditions, the numerical interval into which the foreign matter monitoring value falls is determined, and the type of monitoring cable associated with the foreign matter monitoring device is determined. The associated reference information type is determined according to the monitoring cable type and the numerical interval. The reference information corresponding to the reference information type is obtained based on the monitoring cable type and the preset calling interface. The reference information includes multiple reference parameters and corresponding reference parameter values. The comparison value of the reference parameter is determined according to the numerical interval. The abnormal reference parameter is obtained by comparison processing based on the reference parameter value and the comparison value of the corresponding reference parameter. The type of foreign matter in the monitoring cable is determined according to the abnormal reference parameter. This scheme analyzes the type of foreign matter on the cable through the foreign matter monitoring value, solves the problem that the existing cable monitoring technology lacks a reasonable identification system for foreign matter covered on the cable line, resulting in the inability to timely clean up the foreign matter, affecting the normal operation of the cable, and can realize the automatic identification of foreign matter in the cable line, so as to provide guidance for subsequent cleaning work.

[0053] Figure 2 A flowchart of another cable line foreign body type identification method based on multi-dimensional information provided by an embodiment of the present invention provides an optional specific process for determining reference information, such as Figure 2 As shown, specifically including:

[0054] Step S201, obtaining a foreign object monitoring value monitored by a foreign object monitoring device of a current monitoring cable, and determining a value interval into which the foreign object monitoring value falls when the foreign object monitoring value meets a preset abnormal condition.

[0055] Step S202: Determine the type of monitoring cable associated with the foreign object monitoring device, and determine the associated reference information type according to the monitoring cable type and the numerical range.

[0056] Step S203, determining a plurality of reference parameters according to the monitoring cable type and the reference information type, obtaining reference parameter values ​​of the reference parameters within a preset time based on the preset calling interface, and determining the reference parameters and the reference parameter values ​​as reference information.

[0057] Among them, multiple reference parameters are determined according to the monitoring cable type and the reference information type, and the reference parameter value of the reference parameter within the preset time is obtained based on the preset call interface, and the reference parameter and the corresponding reference parameter value are determined as the reference information. Optionally, a method for determining the reference parameter can be: determining multiple type parameters corresponding to the reference information type and multiple associated foreign body impact parameters of the monitoring cable type, matching the type parameter with the associated foreign body impact parameter, and determining the successfully matched type parameter as the reference parameter, wherein the type parameter is used to characterize the parameter belonging to the reference information type of the parameter classification, and the associated foreign body impact parameter is used to characterize the parameter that produces foreign body impact on the cable of the monitoring cable type. An exemplary example can be that the reference information type is the weather type, the monitoring cable type is the buried cable type, the type parameter of the weather type includes temperature parameter, humidity parameter, rainfall parameter, snowfall parameter, wind parameter, and the associated foreign body impact parameter of the buried cable type includes temperature parameter, humidity parameter, rainfall parameter, vehicle quantity parameter, and vehicle model parameter, and the type parameters that are the same as the associated foreign body impact parameter are temperature parameter, humidity parameter, and rainfall parameter, that is, the reference parameter is temperature parameter, humidity parameter, and rainfall parameter. In another embodiment, multiple type parameters corresponding to the reference information type are determined, and it is queried whether each type parameter has a preset association relationship with the monitoring cable type, and the type parameter having a preset association relationship with the monitoring cable type is determined as a reference parameter.

[0058] Step S204, determining a comparison value of the reference parameter according to the numerical range, performing comparison processing based on the reference parameter value and the comparison value of the corresponding reference parameter to obtain an abnormal reference parameter, and determining the type of foreign matter in the monitoring cable according to the abnormal reference parameter.

[0059] As can be seen from the above, after determining the monitoring cable type and the reference information type, multiple reference parameters are determined according to the monitoring cable type and the reference information type, and the reference parameter values ​​of the reference parameters within the preset time are obtained based on the preset calling interface, and the reference parameters and the corresponding reference parameter values ​​are determined as reference information. This solution determines the reference information by the cable type and the reference information type, which can improve the rationality of the reference information, thereby ensuring the accuracy of foreign object identification.

[0060] Figure 3 A flowchart of another cable line foreign body type identification method based on multi-dimensional information provided by an embodiment of the present invention provides an optional specific process for determining abnormal reference parameters, such as Figure 2 As shown, specifically including:

[0061] Step S301: obtain a foreign object monitoring value monitored by a foreign object monitoring device of a current monitoring cable, and when the foreign object monitoring value meets a preset abnormal condition, determine a value interval into which the foreign object monitoring value falls.

[0062] Step S302: Determine the type of monitoring cable associated with the foreign object monitoring device, and determine the associated reference information type according to the monitoring cable type and the numerical range.

[0063] Step S303: obtaining reference information corresponding to the reference information type based on the monitoring cable type and a preset calling interface, wherein the reference information includes a plurality of reference parameters and corresponding reference parameter values.

[0064] Step S304: determining a comparison value of the reference parameter according to the numerical interval, determining a reference comparison value based on the reference parameter and the corresponding reference parameter value, and comparing the reference comparison value with the corresponding comparison value to obtain a comparison result.

[0065] Among them, the comparison value of each reference parameter is determined according to the numerical interval into which the foreign matter monitoring value falls, the reference comparison value is determined based on each reference parameter and the corresponding reference parameter value, and each reference comparison value is compared with the corresponding comparison value to obtain a comparison result. Optionally, a method for determining the reference comparison value may be: determining whether there is an associated calculation formula for the reference parameter, and if there is an associated calculation formula, substituting the reference parameter value into the corresponding associated calculation formula to calculate the reference comparison value, and if there is no associated calculation formula, determining the reference parameter value as the reference comparison value. An exemplary example may be that the reference parameters include rainfall parameters, snowfall parameters, temperature parameters, and humidity parameters, the preset time is 1 hour, the rainfall parameter value within 1 hour is 2 mm / h, the snowfall parameter value within 1 hour is 0, the temperature parameter value within 1 hour is -2°C, -2°C, -5°C, the humidity parameter value within 1 hour is 30%, 35%, 40%, and there is no corresponding associated calculation formula for the rainfall parameter and the snowfall parameter. Then, the reference comparison values ​​corresponding to the rainfall parameter and the snowfall parameter are 3 mm / h and 0 respectively, the associated calculation formula corresponding to the temperature parameter is the average value calculation formula of each temperature parameter value, and the reference comparison value of the temperature parameter is calculated to be -3°C, and the associated calculation formula corresponding to the humidity parameter is the average value calculation formula of each humidity parameter value, and the reference comparison value of the humidity parameter is calculated to be 35%. In another embodiment, the reference parameters and the corresponding reference parameter values ​​are input into the trained reference comparison value output model to obtain the corresponding reference comparison values.

[0066] Step S305, determining whether the comparison result satisfies a preset comparison success condition of the corresponding reference parameter, determining the reference parameter that satisfies the preset comparison success condition as an abnormal reference parameter, and determining the type of foreign matter in the monitoring cable according to the abnormal reference parameter.

[0067] Among them, the preset comparison success condition is used to characterize the preset condition for judging whether the comparison result is successful. After comparing each reference comparison value with the corresponding comparison value to obtain the comparison result, it is determined whether each comparison result meets the preset comparison success condition of the corresponding reference parameter, and the reference parameter that meets the preset comparison success condition is determined as an abnormal reference parameter. An exemplary example can be that the reference comparison value of the rainfall parameter is 3mm / h, the comparison value is 1.5mm / h, and the preset comparison success condition is that the reference comparison value is greater than the comparison value; the reference comparison value of the snowfall parameter is 0, the comparison value is 2cm / h, and the preset comparison success condition is that the reference comparison value is greater than the comparison value; the reference comparison value of the temperature parameter is -3℃, the comparison value is 0℃, and the preset comparison success condition is that the reference comparison value is lower than the comparison value; the reference comparison value of the humidity parameter is 35%, the comparison value is 60%, and the preset comparison success condition is that the reference comparison value is greater than the comparison value. After comparison, the reference parameters that meet the corresponding preset successful comparison conditions are the rainfall parameter and the temperature parameter, and the abnormal reference parameters are the reference comparison parameter and the temperature parameter.

[0068] As can be seen from the above, the comparison value of each reference parameter is determined according to the numerical interval into which the foreign object monitoring value falls, the reference comparison value is determined based on the reference parameter and the corresponding reference parameter value, the reference comparison value is compared with the corresponding comparison value to obtain the comparison result, and it is determined whether the comparison result meets the preset comparison success condition of the corresponding reference parameter, and the reference parameter that meets the preset comparison success condition is determined as the abnormal reference parameter. This scheme can accurately and reasonably determine the parameters that cause foreign objects to appear on the cable line by determining the comparison value and the reference comparison value and performing comparison processing to obtain the abnormal reference parameter.
