[0042] The cable inspection path generation method based on historical inspection data provided in the embodiment of the present application can be applied to the generation scenario of the cable inspection path. The cable inspection path generation method based on historical inspection data 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.

[0043] Figure 1 A flowchart of a method for generating a cable inspection path based on historical inspection data provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, specifically including:

[0044] Step S101: Acquire the area to be inspected and the corresponding historical inspection path information and historical inspection result information, wherein the historical inspection path information includes the connection relationship between multiple inspection sub-paths and the corresponding inspection times.

[0045] Among them, the area to be inspected is used to represent the area of ​​the cable line to be inspected, and the historical inspection path information is used to represent the various relevant data of the path during the historical cable inspection, which can be the inspection path information recorded before the preset time to the current time, or the inspection path information of a fixed period of time; the historical inspection result information is used to represent the cable status data detected during the historical inspection of the cable; the inspection sub-path is used to represent a path segment in a complete historical inspection path, and the path segment can be divided according to the preset length or inflection point and other conditions; the connection relationship is used to represent whether each inspection sub-path is connected; the number of inspections is used to represent the number of times the inspection sub-path is detected in the historical inspection. Obtaining the area to be inspected and the corresponding historical inspection path information and historical inspection result information can use the historical inspection data of the area to be inspected as the basis for generating the cable inspection path, making the cable inspection path more reasonable.

[0046] Step S102: determining a first weight of each inspection sub-path in the area to be inspected based on the inspection times and the historical inspection result information.

[0047] Among them, the first weight is used to characterize the importance of the inspection of the inspection sub-path. In one embodiment, the first weight of the inspection sub-path is obtained by querying the pre-stored first weight comparison table according to the inspection times of the inspection sub-path and the historical inspection result information. Optionally, the inspection result information includes the fault type of the inspection sub-path and the corresponding type fault times. The fault type is used to characterize the type of fault that occurs in the inspection sub-path, which can be a short circuit type, a high temperature type, and the type fault times are used to characterize the number of occurrences of the same fault type on the inspection sub-path. A first weight determination method can be: calculate the total number of faults of the inspection sub-path according to the type fault times of the inspection sub-path, calculate the proportion of the total number of faults based on the inspection times and the total number of faults of the inspection sub-path, and calculate the fault evaluation value according to the fault type of the inspection sub-path and the corresponding type fault times, multiply the proportion of the total number of faults and the fault evaluation value with the corresponding preset weight and superimpose to obtain the first weight of the inspection sub-path. By calculating the weight of the inspection sub-path through the inspection times and fault data of the inspection sub-path, the accuracy and rationality of the weight of the inspection sub-path can be improved.

[0048] Step S103: Screen and divide the inspection sub-paths according to the first weights to obtain combinations to be connected.

[0049] Among them, the combination to be connected is used to characterize the combination of inspection sub-paths waiting to be connected. In one embodiment, the inspection sub-paths with the same first weight are screened out, and the inspection sub-paths with the same first weight are divided into a combination to be connected. Optionally, it is determined whether the first weight of the inspection sub-path meets the preset weight condition, and the inspection sub-path corresponding to the first weight that meets the preset weight condition is determined as the path to be connected, and the paths to be connected with the same first weight are determined as a combination to be connected, which can screen out inspection sub-paths with low inspection importance, reduce unnecessary inspections, and improve inspection efficiency. An exemplary embodiment may be that the preset weight condition is that the first weight is greater than 0.5. There are currently 10 inspection sub-paths, namely sub-path 1 to sub-path 10, wherein the first weights of sub-paths 1, 2, and 3 are all 0.8, the first weights of sub-paths 4, 5, and 6 are all 0.7, the first weights of sub-paths 7, 8, 9, and 10 are all 0.4, the first weights of sub-paths 1, 2, and 3 are greater than 0.5 and are the same, and the first weights of sub-paths 4, 5, and 6 are greater than 0.5 and are the same, then sub-paths 1, 2, and 3 are determined as one combination to be connected, and sub-paths 4, 5, and 6 are determined as another combination to be connected.

[0050] Step S104: determining a plurality of inspection paths and corresponding second weights based on the combination to be connected and the connection relationship.

[0051] Among them, the inspection path is used to characterize the path that the inspection cable passes through, and the second weight is used to characterize the inspection importance of the inspection path. In one embodiment, the paths to be connected in the combination to be connected are connected based on the connection relationship and the preset connection rules to obtain an inspection path, and the first weight corresponding to the combination to be connected is determined as the second weight of the inspection path. Optionally, a path to be connected is randomly selected in the combination to be connected, and the first connection path connected to the selected path to be connected in the combination to be connected is determined according to the connection relationship between the inspection sub-paths, and the selected path to be connected is connected with the first connection path to determine an inspection path, and the first weight of the path to be connected is determined as the second weight of the inspection path, and the corresponding inspection path connection is continued for the unconnected paths to be connected in the combination to be connected until all the paths to be connected in the combination to be connected are connected. The inspection sub-paths with the same weight and connection relationship are connected and determined as the inspection path, which can unify the weights of each section in the inspection path, which is beneficial to cable inspection.

[0052] Step S105: determine the actual wiring complexity of the inspection path, determine the inspection priority of the inspection path based on the second weight and the actual wiring complexity, and generate corresponding inspection paths in sequence according to the inspection priority.

[0053] Among them, the actual wiring complexity is used to characterize the complexity of the cable line on the inspection path, and the inspection priority is used to characterize the order in which the inspection path is inspected. A method for determining the actual wiring complexity may be to determine the average value of the pre-stored wiring complexity of each inspection sub-path in the inspection path as the actual wiring complexity of the inspection path, or to compare the inspection path with the pre-stored path, and determine the pre-stored wiring complexity corresponding to the successfully compared pre-stored path as the complexity of the inspection path. In one embodiment, the sub-wiring complexity of each inspection sub-path in the recorded inspection path is obtained, and the average value of the sub-wiring complexity is determined as the actual wiring complexity of the inspection path. The comprehensive evaluation value of the inspection path is calculated according to the second weight and the actual wiring complexity, and the priority of the inspection path is determined according to the order of the comprehensive evaluation value from large to small, and the corresponding inspection path is generated in sequence according to the inspection priority of the inspection path. Optionally, a method for determining inspection priority may also be to prioritize multiple inspection paths in order of second weights from large to small. When the second weights of the inspection paths are the same, the inspection paths with greater actual wiring complexity are arranged in front, so that inspection paths with higher inspection importance and more complex wiring can be prioritized to improve inspection efficiency. An exemplary embodiment may be that there are five inspection paths, namely path a, path b, path c, path d and path e, and the corresponding second weights are 0.8, 0.7, 0.9, 0.6, and 0.8, respectively, wherein the second weights of path a and path e are the same, the actual wiring complexity of path a is 60%, and the actual wiring complexity of path e is 80%, and the actual wiring complexity of path e is greater than that of path a, then path e is arranged in front of path a, and the priority ranking obtained in order of the second weights from large to small is path c, path e, path a, path b, and path d.

[0054] As can be seen from the above, the area to be inspected and the corresponding historical inspection path information and historical inspection result information are obtained. The historical inspection path information includes the connection relationship of multiple inspection sub-paths and the corresponding inspection times. The first weight of each inspection sub-path in the area to be inspected is determined based on the inspection times of the inspection sub-paths and the historical inspection result information. The inspection sub-paths are screened and divided according to the first weights of the inspection sub-paths to obtain a combination to be connected. Based on the combination to be connected and the connection relationship of the inspection sub-paths, multiple inspection paths and corresponding second weights are determined, and the actual wiring complexity of the inspection path is determined. The inspection priority of the inspection path is determined based on the second weight of the inspection path and the actual wiring complexity, and the corresponding inspection paths are generated in sequence according to the inspection priority. This solution generates cable inspection paths through historical inspection data, which solves the problem that the existing cable inspection technology will cause a large number of meaningless inspections for complex cable lines, and the inspection efficiency is poor, resulting in untimely detection of cable anomalies, which affects the safe operation of the power system. It can improve the efficiency of cable inspections, timely inspect cable anomalies and perform repairs, and ensure the normal operation of the cable.

[0055] Figure 2 A flowchart of a method for determining a first weight of each inspection sub-path in an area to be inspected provided by an embodiment of the present invention, such as Figure 2 As shown, specifically including:

[0056] Step S201: Acquire the area to be inspected and the corresponding historical inspection path information and historical inspection result information, wherein the historical inspection path information includes the connection relationship between multiple inspection sub-paths and the corresponding inspection times.

[0057] Step S202: calculate the total number of failures of the inspection sub-path according to the number of failures of the type, calculate the proportion of the total number of failures based on the inspection times and the total number of failures, and calculate the failure assessment value according to the failure type and the corresponding number of failures of the type, multiply the proportion of the total number of failures and the failure assessment value with the corresponding preset weights and superimpose them to obtain the first weight of the inspection sub-path.

[0058] Among them, the inspection result information includes the fault type of the inspection sub-path and the corresponding number of type faults. A method for determining the first weight may be: calculating the total number of faults of the inspection sub-path according to the number of type faults of the inspection sub-path, calculating the proportion of the total number of faults based on the number of inspections and the total number of faults of the inspection sub-path, and calculating the fault assessment value according to the fault type of the inspection sub-path and the corresponding number of type faults, multiplying the proportion of the total number of faults and the fault assessment value with the corresponding preset weight and superimposing them to obtain the first weight of the inspection sub-path. An optional method for calculating the fault assessment value may be, when there are multiple fault types in the inspection sub-path, calculating the ratio of the number of type faults to the number of inspections, querying the type fault assessment value mapping table corresponding to the fault type according to the ratio to obtain the type fault assessment value, and superimposing the type fault assessment values ​​to obtain the fault assessment value. An exemplary example may be that the currently determined inspection subpath is inspection subpath a, the number of inspections of inspection subpath a is 20 times, the fault types include high temperature type and high humidity type, the number of high temperature type faults is 5 times, the number of high humidity type faults is 4 times, then the total number of faults of inspection subpath a is 9 times (5+4), the total number of faults accounts for 0.45 (9 / 20), the ratio of high temperature type faults to inspection times is 0.25, and the ratio of high humidity type faults to inspection times is 0. .2, the query obtains that the weight corresponding to the high temperature type fault assessment value mapping table accounting for 0.25 is 0.35, and the high humidity type fault assessment value corresponding to the high humidity type fault assessment value mapping table accounting for 0.2 is 0.25, then the fault assessment value is 0.6 (0.35 + 0.25), the preset weight of the total number of faults is 0.6, and the preset weight of the fault assessment value is 0.4, then the first weight of the inspection sub-path a is calculated to be 0.51 (0.45 * 0.6 + 0.6 * 0.4). In another embodiment, a method for calculating the fault assessment value can be to input the fault type of the inspection sub-path and the corresponding number of type faults into a trained fault assessment model, and output the fault assessment value of the inspection sub-path.

[0059] Step S203: Screen and divide the inspection sub-paths according to the first weights to obtain combinations to be connected.

[0060] Step S204: determine a plurality of inspection paths and corresponding second weights based on the combination to be connected and the connection relationship.

[0061] Step S205: determine the actual wiring complexity of the inspection path, determine the inspection priority of the inspection path based on the second weight and the actual wiring complexity, and generate corresponding inspection paths in sequence according to the inspection priority.

[0062] As can be seen from the above, the total number of faults of the inspection subpath is calculated according to the number of type faults of the inspection subpath, the proportion of the total number of faults is calculated based on the number of inspections of the inspection subpath and the total number of faults, and the fault assessment value is calculated according to the fault type of the inspection subpath and the corresponding number of type faults, and the proportion of the total number of faults and the fault assessment value are multiplied and superimposed with the corresponding preset weight to obtain the first weight of the inspection subpath. This solution calculates the weight of the inspection subpath through the inspection number of the inspection subpath and the fault data, which can improve the accuracy and rationality of the weight of the inspection subpath.

[0063] Figure 3 A flowchart of a method for determining multiple inspection paths and corresponding second weights provided by an embodiment of the present invention, such as Figure 3 As shown, specifically including:

[0064] Step S301: Acquire the area to be inspected and the corresponding historical inspection path information and historical inspection result information, wherein the historical inspection path information includes the connection relationship between multiple inspection sub-paths and the corresponding inspection times.

[0065] Step S302: Determine a first weight of each inspection sub-path in the area to be inspected based on the inspection times and the historical inspection result information.

[0066] Step S303: Screen and divide the inspection sub-paths according to the first weights to obtain combinations to be connected.

[0067] Step S304: randomly select a path to be connected in the combination to be connected, determine a first connection path connected to the path to be connected in the combination to be connected according to the connection relationship, connect the path to be connected with the first connection path to determine an inspection path, and determine the first weight of the path to be connected as the second weight of the inspection path, and continue to perform corresponding inspection path connections on the unconnected paths to be connected in the combination to be connected until all the paths to be connected in the combination to be connected are connected.

[0068] Among them, a path to be connected is randomly selected in the combination to be connected, and the first connection path connected to the selected path to be connected in the combination to be connected is determined according to the connection relationship between the inspection sub-paths, and the selected path to be connected is connected with the first connection path. Optionally, in the combination to be connected, when a second connection path that has a connection relationship with the first connection path is determined, the first connection path is connected with the second connection path until there is no connection relationship between the connection paths in the combination to be connected, so as to determine a patrol path, and the first weight of the path to be connected is determined as the second weight of the patrol path, and the corresponding patrol path connection is continued for the unconnected paths to be connected in the combination to be connected until all the paths to be connected in the combination to be connected are connected. An exemplary example may be that the current connection is to-be-connected combination 1, the first weight of the to-be-connected path in the to-be-connected combination 1 is 0.6, the to-be-connected combination 1 includes to-be-connected paths a, b, c, d, e, f, g, h, a to-be-connected path a is randomly selected, and it is determined according to the connection relationship that the path to-be-connected path in the to-be-connected combination 1 is connected to the to-be-connected path b, then the to-be-connected path a is connected to the to-be-connected path b, and it is determined according to the connection relationship that the path to-be-connected path is connected to the to-be-connected path c, then the to-be-connected path c is connected to the to-be-connected path b, and it is not determined that there is a path to-be-connected path in the to-be-connected combination c has a connection relationship between the paths to be connected, then the paths to be connected a-path to be connected b-path to be connected c are determined as a patrol path, and similarly, the unconnected paths to be connected d, e, f, g, h in the combination to be connected are connected as patrol paths, and the patrol paths obtained are path to be connected d-path to be connected e-path to be connected f, path to be connected g, and path to be connected h, wherein the paths to be connected g and the paths to be connected h do not have a connection relationship in the combination to be connected, then the paths to be connected g and the paths to be connected h are directly determined as patrol paths respectively, and the second weights of the determined patrol paths are all 0.6. In another embodiment, the paths to be connected that have a connection relationship in the combination to be connected are connected to obtain a plurality of path segments to be connected in series, the positions of the path segments to be connected in series are determined, and the path segments to be connected in series are connected according to the principle of connecting the paths in series at the nearest preset positions to obtain the patrol path.

[0069] Step S305: determine the actual wiring complexity of the inspection path, determine the inspection priority of the inspection path based on the second weight and the actual wiring complexity, and generate corresponding inspection paths in sequence according to the inspection priority.

[0070] As can be seen from the above, a path to be connected is randomly selected in the combination to be connected, and the first connection path connected to the selected path to be connected in the combination to be connected is determined according to the connection relationship between the inspection sub-paths, and the selected path to be connected is connected with the first connection path to determine a patrol path, and the first weight of the path to be connected is determined as the second weight of the patrol path, and the corresponding patrol path connection is continued for the unconnected paths to be connected in the combination to be connected until all the paths to be connected in the combination to be connected are connected. This solution can unify the weights of each section in the patrol path by connecting the patrol sub-paths with the same weight and connection relationship and determining them as patrol paths, which is beneficial to cable patrol.

Figure 4 As shown, the system specifically includes:

[0072] The acquisition module 101 is used to acquire the area to be inspected and the corresponding historical inspection path information and historical inspection result information, wherein the historical inspection path information includes the connection relationship of multiple inspection sub-paths and the corresponding inspection times;

[0076] The path generation module 105 is used to generate corresponding inspection paths in sequence according to the inspection priorities.

[0077] It can be seen from the above scheme that the area to be inspected and the corresponding historical inspection path information and historical inspection result information are obtained. The historical inspection path information includes the connection relationship of multiple inspection sub-paths and the corresponding inspection times. The first weight of each inspection sub-path in the area to be inspected is determined based on the inspection times of the inspection sub-paths and the historical inspection result information. The inspection sub-paths are screened and divided according to the first weights of the inspection sub-paths to obtain a combination to be connected. Based on the combination to be connected and the connection relationship of the inspection sub-paths, multiple inspection paths and corresponding second weights are determined, and the actual wiring complexity of the inspection path is determined. The inspection priority of the inspection path is determined based on the second weight of the inspection path and the actual wiring complexity, and the corresponding inspection paths are generated in sequence according to the inspection priority. This scheme generates cable inspection paths through historical inspection data, which solves the problem that the existing cable inspection technology will cause a large number of meaningless inspections for complex cable lines, and the inspection efficiency is poor, resulting in untimely detection of cable anomalies, which affects the safe operation of the power system.
