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.

[0046] The cable inspection path generation method based on hidden danger points provided in the embodiment of the present application can be applied to the cable inspection path generation scenario. The cable inspection path generation method based on hidden danger points 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.

[0047] Figure 1 A flowchart of a method for generating a cable inspection path based on a potential danger point is provided in an embodiment of the present invention, such as Figure 1 As shown, specifically including:

[0048] Step S101, obtaining a cable line diagram of the area to be inspected and the collected data of the corresponding monitoring nodes within a preset time.

[0049] Among them, the area to be inspected is used to characterize the area where the cable line waiting for inspection is located, the cable line diagram is a schematic diagram of the pre-stored cable line, the monitoring node is used to characterize the node for monitoring the operation of the cable line, and the collected data is used to characterize the parameter data of the corresponding parameter type collected by the monitoring node. The cable line diagram of the area to be inspected and the collected data of the corresponding monitoring node within the preset time are obtained. An illustrative example can be that the preset time is 30 minutes, there are 3 cable laying areas, namely area 1, area 2 and area 3, each cable laying area is provided with a variety of different types of monitoring nodes, and the corresponding stored cable line diagrams are line diagram a, line diagram b and line diagram c, respectively. The current area to be inspected is area 2, then the line diagram b corresponding to area 2 and the collected data of each monitoring node in area 2 within 30 minutes are obtained.

[0050] Step S102: determining a plurality of abnormal monitoring nodes that meet preset abnormal conditions based on the collected data, obtaining position data of the abnormal monitoring nodes, and screening the abnormal monitoring nodes according to the position data to obtain a plurality of potential hazard nodes.

[0051] Among them, the preset abnormal conditions are conditions for judging whether the collected data is abnormal, the abnormal monitoring nodes are used to characterize the corresponding monitoring nodes with abnormal collected data, the position data are used to characterize the position of the abnormal monitoring nodes in the area to be inspected, and the hidden danger nodes are used to characterize the monitoring nodes that may have hidden dangers of failure. Based on the collected data of the monitoring nodes within the preset time, multiple abnormal monitoring nodes that meet the preset abnormal conditions are determined. An optional method may be to determine the change trend of the collected values ​​within the preset time, determine the corresponding comparison threshold based on the collection type, determine the number of collected parameter values ​​in the collected data that are greater than the comparison threshold, and determine the monitoring node corresponding to the collected data as an abnormal monitoring node when the change trend is an upward trend and the number is greater than the preset number.

[0052] After the abnormal monitoring node is determined, the location data of the abnormal monitoring node is obtained, and the abnormal monitoring node is screened according to the location data to obtain multiple hidden danger nodes. In one embodiment, based on the location data of the abnormal monitoring node, a combination of adjacent nodes whose location distance is less than a first preset distance is determined in the abnormal monitoring node, and the monitoring type of the adjacent nodes in the adjacent node combination is determined. When the monitoring types are the same, an adjacent node is randomly selected to be determined as a hidden danger node to be determined, and the hidden danger node to be determined and the remaining abnormal monitoring nodes are determined as hidden danger nodes. An exemplary example can be that a total of 6 abnormal monitoring nodes are determined, namely nodes 1, 2, 3, 4, 5, and 6, and the preset distance is 15 meters, wherein, according to the location data of each abnormal node, it is determined that the location distance between node 2 and node 3 is 10 meters, which is less than the preset distance, that is, node 2 and node 3 are adjacent node combinations, and the monitoring types of node 2 and node 3 are both temperature types. Node 2 is randomly selected as a hidden danger node to be determined, and nodes 1, 2, 4, 5, and 6 are determined as hidden danger nodes. In another embodiment, a method for screening nodes with hidden dangers to be determined in a combination of adjacent nodes with the same monitoring type may also be to obtain the historical failure frequency of each adjacent node and determine the adjacent node with the largest historical failure frequency as the node with hidden dangers to be determined.

[0053] Step S103: based on the location data, the potential danger nodes are concentratedly divided to obtain a plurality of concentrated node combinations and the number of combined nodes.

[0054] Among them, the concentrated node combination is used to characterize the combination of hidden danger nodes concentrated in a certain range, and the number of combined nodes is used to characterize the number of hidden danger nodes contained in the concentrated node combination. After determining multiple hidden danger nodes, the multiple hidden danger nodes are concentratedly divided based on the position data of the hidden danger nodes to obtain multiple concentrated node combinations and the number of combined nodes. In one embodiment, the distance between each hidden danger node is determined based on the position data of the hidden danger node, and one hidden danger node in each preset direction is randomly selected as a division reference point, and the hidden danger node whose distance from the division reference point is less than the preset division distance is determined as a concentrated node combination, and the number of combined nodes is counted. When there are hidden danger nodes that have not been divided, the hidden danger nodes that have not been divided are divided into the nearest concentrated node combination. In another embodiment, a concentrated division range is preset, and the hidden danger nodes within the concentrated division range are determined based on the position data of each hidden danger node and determined as a concentrated node combination, and the number of hidden danger nodes in the concentrated node combination is counted and determined as the number of combined nodes. The hidden danger nodes are concentratedly divided based on the position data, and the hidden danger nodes with a closer distance can be connected according to the corresponding node connection conditions, thereby improving the rationality of the cable inspection path and the inspection efficiency.

[0055] Step S104: Comprehensively evaluate the centralized node combination according to the number of combined nodes and the collected data of the potential danger nodes.

[0056] Among them, after a plurality of hidden danger nodes are concentratedly divided to obtain a plurality of concentrated node combinations and the number of combined nodes, a comprehensive evaluation is performed on the concentrated node combinations according to the number of combined nodes and the collected data of each hidden danger node. In one embodiment, the abnormality of the concentrated node combination is determined according to the collected data of the hidden danger node, and the number of combined nodes and the abnormality of the concentrated node combination are multiplied and superimposed with the preset quantity weight and the preset abnormal weight to obtain the comprehensive evaluation value of each concentrated node combination. Comprehensively evaluating the concentrated node combination can determine the inspection urgency of each concentrated node combination and improve the rationality of the cable inspection path.

[0057] Step S105: Based on the evaluation result of the comprehensive evaluation and the location data, the potential danger nodes are connected to obtain a cable inspection path.

[0058] Among them, the cable inspection path is used to characterize the route referenced when inspecting the cable. After the centralized node combination is comprehensively evaluated, the potential danger nodes are connected based on the evaluation results of the comprehensive evaluation of the centralized node combination and the location data of the potential danger nodes to obtain the cable inspection path. In one embodiment, the combination connection order of the centralized node combination is determined based on the comprehensive evaluation value of the centralized node combination and the location data of the potential danger nodes, the node connection order of the potential danger nodes in the centralized node combination is determined according to the abnormality degree of the centralized node combination, and the potential danger nodes are connected based on the combination connection order and the node connection order to obtain the cable inspection path. An example of a cable inspection path connection may be that there are three concentrated node combinations, namely concentrated node combinations a, b and c, and the determined combination connection order is a to b to c. The hidden danger nodes included in the concentrated node combination a are nodes A, B, and C, and the determined node connection order is A to B to C. The hidden danger nodes included in the concentrated node combination b are nodes D, E, and F, and the determined node connection order is D to E to F. The hidden danger nodes included in the concentrated node combination c are nodes G, H, and I, and the determined node connection order is G to H to I. Then, the position of each hidden danger node in the cable line diagram is determined according to the preset association identifier of the hidden danger node. In the cable line diagram, the shortest distance connection of the hidden danger nodes is performed starting from the concentrated node combination a that is arranged in the first place. After the nodes a, b, and c in the combination a are connected according to the node connection order, the hidden danger nodes in the next concentrated node combination b are connected until all the hidden danger nodes are connected. The cable inspection path is obtained as node A-node B-node C-node D-node E-node F-node G-node H-node I. Determining the combined connection sequence and the node connection sequence, and connecting the potential danger nodes based on the combined connection sequence and the node connection sequence to obtain the cable inspection path can make the inspection sequence of the potential danger nodes more reasonable and improve the inspection efficiency.

[0059] As can be seen from the above, the cable line diagram of the area to be inspected and the corresponding collected data of the monitoring nodes within a preset time are obtained, multiple abnormal monitoring nodes that meet the preset abnormal conditions are determined based on the collected data of the monitoring nodes within the preset time, the location data of the abnormal monitoring nodes are obtained, the abnormal monitoring nodes are screened according to the location data to obtain multiple hidden danger nodes, the hidden danger nodes are concentrated and divided based on the location data to obtain multiple concentrated node combinations and the number of combined nodes, the concentrated node combinations are comprehensively evaluated according to the number of combined nodes and the collected data of the hidden danger nodes, and the hidden danger nodes are connected based on the evaluation results of the comprehensive evaluation and the location data to obtain the cable inspection path. This solution generates an inspection path by determining the hidden danger points in the cable line, which solves the problem that the inspection logic and rationality of the existing cable inspection technology are poor, resulting in low inspection efficiency and failure to timely discover the location of cables with safety hazards. It can improve the rationality of the inspection path and the inspection efficiency, and timely discover cable hidden dangers.

[0060] Figure 2 A flowchart of a comprehensive evaluation method for centralized node combination provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, specifically including:

[0061] Step S201: Obtain a cable line diagram of the area to be inspected and the collected data of the corresponding monitoring nodes within a preset time.

[0062] Step S202: determining a plurality of abnormal monitoring nodes that meet preset abnormal conditions based on the collected data, obtaining position data of the abnormal monitoring nodes, and screening the abnormal monitoring nodes according to the position data to obtain a plurality of potential hazard nodes.

[0063] Step S203: based on the location data, the potential danger nodes are concentratedly divided to obtain a plurality of concentrated node combinations and the number of combined nodes.

[0064] Step S204: determine the abnormality level of the centralized node combination according to the collected data of the potential danger node, multiply the number of combined nodes and the abnormality level by a preset number weight and a preset abnormality weight respectively, and superimpose them to obtain a comprehensive evaluation value of the centralized node combination.

[0065] Among them, the preset quantity weight is used to characterize the influence of the number of combined nodes on the comprehensive evaluation of the concentrated node combination, and the preset abnormal weight is used to characterize the influence of the abnormal degree on the comprehensive evaluation of the concentrated node combination. The abnormal degree of the concentrated node combination is determined according to the collected data of the hidden danger node. Optionally, the parameter change rate within a preset time is calculated according to the collected data of the hidden danger node, and the abnormal level of the hidden danger node is determined based on the parameter change rate. The average abnormal level of the hidden danger nodes in the concentrated node combination is calculated, and the preset abnormal level mapping table is queried according to the average abnormal level to obtain the abnormal degree of the concentrated node combination. The number of combined nodes and the abnormal degree are multiplied and superimposed with the preset quantity weight and the preset abnormal weight to obtain the comprehensive evaluation value of the concentrated node combination. An exemplary example may be that the preset abnormal degree mapping table is shown in the following table:

[0066] Average abnormality level Abnormality Level 1 25％ Level 2 50％ Level 3 75％ Level 4 100％

[0067] The above comparison table is a preset abnormality degree mapping table, which is specifically described as follows: when the average abnormality level of the hidden danger nodes in the centralized node combination is level one, the abnormality level of the centralized node combination is 25%; when the average abnormality level of the hidden danger nodes in the centralized node combination is level two, the abnormality level of the centralized node combination is 50%; when the average abnormality level of the hidden danger nodes in the centralized node combination is level three, the abnormality level of the centralized node combination is 75%; when the average abnormality level of the hidden danger nodes in the centralized node combination is level four, the abnormality level of the centralized node combination is 100%;

[0068] There are three centralized node combinations, namely centralized node combination a, centralized node combination b and centralized node combination c. Taking centralized node combination a as an example, centralized node combination a includes hidden danger node 1, hidden danger node 2 and hidden danger node 3. Hidden danger node 1 is a temperature monitoring node, hidden danger node 2 is a humidity monitoring node, and hidden danger node 3 is a load monitoring node. According to the collected data of each hidden danger node, the parameter change rates within the preset time are calculated to be 20°C / h, 30% / h, and 10A / h respectively. According to the change rates of each parameter, the abnormal level comparison table of temperature type, humidity type and load type is queried respectively to obtain the abnormal level of hidden danger node 1 is level 4, the abnormal level of hidden danger node 2 is level 3, and the abnormal level of hidden danger node 3 is level 2, then the average abnormal level is level 3. According to the current average abnormal level, the preset abnormal level mapping table is queried to obtain the corresponding abnormal level of 75%, that is, the abnormal level of centralized node combination a is 75%, the preset quantity weight is 0.3, and the preset abnormal weight is 0.7. Then the comprehensive evaluation value of centralized node combination a is 1.425 (3*0.3+75%*0.7). In another embodiment, the inspection difficulty of each centralized node combination is determined, and a comprehensive evaluation is performed on the centralized node combination according to the number of combined nodes and the inspection difficulty.

[0069] Step S205: Based on the evaluation result of the comprehensive evaluation and the location data, the potential danger nodes are connected to obtain a cable inspection path.

[0070] As can be seen from the above, after dividing and obtaining multiple centralized node combinations and the number of combined nodes, the abnormality of the centralized node combination is determined according to the collected data of the hidden danger node, and the number of combined nodes and the abnormality are multiplied and superimposed with the preset number weight and the preset abnormal weight to obtain the comprehensive evaluation value of the centralized node combination. This solution can determine the inspection urgency of each centralized node combination and improve the rationality of the cable inspection path by comprehensively evaluating the centralized node combination.

[0071] Figure 3 A flow chart of a cable inspection path connection method provided by an embodiment of the present invention, such as Figure 3 As shown, specifically including:

[0072] Step S301: Obtain a cable line diagram of the area to be inspected and the collected data of the corresponding monitoring nodes within a preset time.

[0073] Step S302: determining a plurality of abnormal monitoring nodes that meet preset abnormal conditions based on the collected data, obtaining position data of the abnormal monitoring nodes, and screening the abnormal monitoring nodes according to the position data to obtain a plurality of potential hazard nodes.

[0074] Step S303: based on the location data, the potential danger nodes are concentratedly divided to obtain a plurality of concentrated node combinations and the number of combined nodes.

[0075] Step S304: Comprehensively evaluate the centralized node combination according to the number of combined nodes and the collected data of the potential danger nodes.

[0076] Step S305: determine the combined connection order of the centralized node combination based on the comprehensive evaluation value and the location data, determine the node connection order of the potential danger nodes in the centralized node combination according to the abnormality level, and connect the potential danger nodes based on the combined connection order and the node connection order to obtain a cable inspection path.

[0077] Among them, the combined connection order of the centralized node combination is determined based on the comprehensive evaluation value and the position data, and the node connection order of the hidden danger nodes in the centralized node combination is determined according to the abnormal level of the hidden danger node. An optional determination method may be to determine the node connection order of the hidden danger nodes in the centralized node combination in order from high to low abnormal levels, and randomly arrange them when the abnormal levels of the hidden danger nodes are the same. The hidden danger nodes are connected based on the combined connection order and the node connection order to obtain the cable inspection path. Optionally, the centralized node combination with the largest comprehensive evaluation value is arranged in the first place and determined as the first connection combination, the combined distance between the centralized node combination and the first connection combination is determined according to the position data, and the combined connection order of the centralized node combination is determined based on the combined distance. In one embodiment, a second connection combination whose combination distance is less than a preset distance is determined. If there are multiple second connection combinations, the second connection combinations are arranged in descending order according to the comprehensive evaluation value. The remaining concentrated node combinations are sorted based on the second connection combination arranged at the end until the sorting is completed. An exemplary example may be that the preset distance is 20 meters, there are 4 concentrated node combinations, namely combination a, combination b, combination c and combination d, and the comprehensive evaluation values ​​are 1.8, 1.5, 1.6, and 1.4 respectively. The concentrated node combination with the largest comprehensive evaluation value is combination a, and combination a is arranged in the first place. The distances between combination b, combination c, and combination d and combination a are 15 meters, 18 meters, and 30 meters respectively. The distances between combination b, combination c and combination a are all less than 20 meters. The comprehensive evaluation value of combination c is greater than combination b, and combination c is arranged before combination b. The final combined connection order is combination a-combination c-combination b-combination d. In another embodiment, the concentrated node combinations are sorted in descending order according to the comprehensive evaluation values, and when the comprehensive evaluation values ​​are the same, they are randomly arranged.

[0078] From the above, it can be seen that the combined connection order of the centralized node combination is determined based on the comprehensive evaluation value and the location data, the node connection order of the hidden danger nodes in the centralized node combination is determined according to the abnormal level of the hidden danger node, and the hidden danger nodes are connected based on the combined connection order and the node connection order to obtain the cable inspection path. This scheme can make the inspection order of the hidden danger nodes more reasonable and improve the inspection efficiency by determining the combined connection order and the node connection order, and connecting the hidden danger nodes based on the combined connection order and the node connection order to obtain the cable inspection path.
