[0022] Example 1

[0023] According to an embodiment of the present invention, an embodiment of a method for inspecting distribution network lines is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0024] Figure 1 is a flow chart of a method for inspecting a distribution network line according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0025] Step S102, extracting the three-dimensional model of the distribution network line to obtain grid structure data, wherein the grid structure data is used to characterize the topological relationship between multiple power devices in the distribution network line.

[0026] The three-dimensional model in the above steps is a model that can describe the characteristics of the distribution network line. It can be a CIM (Common Information Model) model, a GIS (Geographic Information System) model, or a BIM (Building Information Modeling) model, but is not limited to these.

[0027] The grid structure data in the above steps may include but are not limited to the device name, device type, device geographical coordinates, topological relationship between devices, etc. of the power equipment in the distribution network line.

[0028] In an optional embodiment, the information of the power equipment in the distribution network line, the characteristics of the distribution network line and other data can be exported from the CIM corresponding to the distribution network line through the CIM standard interface, and then data cleaning is performed to extract the data related to the grid structure, such as the device name, device type, device geographical coordinates, and the topological relationship between devices from the data exported by the CIM. Subsequently, the data such as the device name, device type, device geographical coordinates, and the topological relationship between devices are formatted and standardized to obtain the grid structure data.

[0029] In another optional embodiment, the GIS model corresponding to the distribution network line can be extracted from the GIS system, and then the GIS model can be parsed using graph parsing technology to obtain grid structure data including device name, device type, device geographic coordinates, and topological relationships between devices.

[0030] Step S104, determining a patrol path based on the grid structure data and the status data of the plurality of power devices, wherein the patrol path is used to characterize a path for patrolling the plurality of devices to be patrolled among the plurality of power devices, and the status data is used to characterize whether the plurality of power devices have abnormalities.

[0031] The status data in the above steps may include but are not limited to electrical parameters, temperature data, humidity data, vibration data, etc.

[0032] The inspection path in the above steps is a path determined for the equipment to be inspected in the distribution network line. When determining the inspection path, it is necessary to consider the topological relationship between the power equipment, whether there are abnormalities in the status data of multiple power equipment, etc., in order to improve the rationality of the inspection route.

[0033] In an optional embodiment, the status data of multiple power equipment can be collected, including the operating status, electrical parameters, temperature data, vibration data, environmental data and other information of the equipment, to determine whether the equipment has abnormal conditions. It is also possible to determine the equipment with higher importance based on the equipment type of the electrical equipment in the grid structure data. Equipment with abnormal conditions and equipment with higher importance are taken as equipment to be inspected, and then based on the topological relationship between the power equipment in the grid structure data, multiple paths that can cover all the equipment to be inspected are determined, and the one with the shortest path length is selected from the multiple paths as the inspection path. Step S106, the inspection path is divided based on the grid structure data to obtain multiple inspection units.

[0034] The inspection units in the above steps are units with similar inspection workloads, and can be regarded as detailed divisions of the inspection tasks for the entire inspection path.

[0035] In an optional embodiment, the distance between two adjacent devices to be inspected in the patrol path is determined based on the device geographic coordinates in the grid structure data. Starting from the first device to be inspected at the starting point of the patrol path, the devices to be inspected at a preset distance are divided into a patrol unit according to the topological relationship between the devices to be inspected in the patrol path, and then starting from the first patrol device among the remaining devices to be inspected in the patrol path, the devices to be inspected at a preset distance are divided into a patrol unit according to the topological relationship between the devices to be inspected in the patrol path, and so on, to obtain multiple patrol units. The preset distance is a pre-set distance, which can be 5000 meters or 3000 meters, but is not limited thereto.

[0036] In another optional embodiment, the distance between two adjacent devices to be inspected in the inspection path is determined based on the device geographic coordinates in the grid structure data. Then, based on the means of transportation selected during the inspection and the speed of the means of transportation, the time from one device to be inspected to another adjacent device to be inspected can be determined. Starting from the first device to be inspected at the starting point of the inspection path, the devices to be inspected that can be inspected within the preset time are divided into an inspection unit based on the topological relationship between the devices to be inspected in the inspection path, and then starting from the first inspection device among the remaining devices to be inspected in the inspection path, the devices to be inspected that can be inspected within the preset time are divided into an inspection unit based on the topological relationship between the devices to be inspected in the inspection path, and so on, to obtain multiple inspection units. Among them, the preset time is a pre-set time, which can be 5 hours or 3 hours, but is not limited to this.

[0037] The inspection path is divided into multiple inspection units, which refines the granularity of the inspection tasks and divides the inspection tasks of the inspection path into smaller task packages, thus enhancing the flexibility of task assignment and scheduling. The inspection tasks of different inspection units are assigned to different staff members, which realizes the reasonable allocation of human resources. By having staff members perform the inspection tasks of the inspection units in parallel, the inspection efficiency of the entire inspection path can be improved.

[0038] Step S108: inspect the distribution network lines according to multiple inspection units.

[0039] In an optional embodiment, the allocation of multiple inspection units can be pushed to the team leader of the inspection personnel, and the team leader assigns the inspection tasks of different inspection units to different inspection personnel through the system, so that different inspection personnel perform the inspection of the distribution network line in parallel. After the inspection personnel determine the inspection unit, they start to inspect the inspection unit. During the inspection process, every time they arrive at the location of a device to be inspected, they check in and locate through the mobile terminal APP (Application) to ensure that the inspection personnel are in place. When it is found that the equipment to be inspected has defects and hidden dangers, the operating status, defect hidden dangers, defect photos, etc. of the equipment to be inspected are uploaded to the system through the mobile terminal APP, and the system generates a problem list and pushes the problem list to the defect elimination personnel, who promptly eliminate the defects of the line equipment to ensure the power supply reliability of the distribution network line. When the inspection personnel finish the inspection, the inspection tasks of the inspection unit are archived through the mobile terminal APP to achieve closed-loop management of the entire inspection task plan.

[0040] In another optional embodiment, the inspection robot can assign the inspection tasks of different inspection units to different inspectors according to the inspectors' work schedules, ensure the workload of each inspector is balanced, and generate an inspection task allocation table. The inspection robot sends the inspection task allocation table to each inspector and collects the actual inspection situation and feedback information of the inspectors in performing the inspection tasks, so as to adjust the allocation of inspection tasks in a timely manner and ensure the efficient implementation of the inspection work.

[0041] In an embodiment of the present invention, the three-dimensional model of the distribution network line is extracted to obtain grid structure data; based on the grid structure data and the status data of multiple power equipment, the inspection path is determined, and the status data is used to characterize whether the multiple power equipment is abnormal; the inspection path is divided based on the grid structure data to obtain multiple inspection units; and the distribution network line is inspected according to the multiple inspection units. It is easy to notice that the three-dimensional model of the distribution network line is extracted to obtain the grid structure data, which can improve the efficiency of obtaining the grid structure data, and the grid structure data is used as the basis for determining the inspection path. Based on the grid structure data and the status data of multiple power equipment, the inspection path is determined, and a reasonable inspection path can be determined according to whether the power equipment is abnormal and the topological relationship between the multiple power equipment. Based on the grid structure data, the inspection path is divided to obtain multiple inspection units, and the distribution network line is inspected according to the multiple inspection units. The multiple inspection units can be used as inspection tasks that can be executed in parallel. By inspecting the multiple inspection units in parallel, the purpose of improving the inspection efficiency of the distribution network line is achieved, thereby solving the technical problem of low inspection efficiency of the distribution network line.

[0042] Optionally, the inspection path is divided based on the grid structure data to obtain multiple inspection units, including: based on the grid structure data, determining the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, wherein the movement time is the time required to move from any device to be inspected to another device to be inspected adjacent to the device to be inspected, and the inspection time is the time required to inspect the corresponding device to be inspected; based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, the inspection path is divided using preset inspection times to obtain multiple inspection units.

[0043] The preset inspection time in the above steps is a pre-set time, which can be preset according to actual application conditions, and no restriction is imposed on the specific value of the preset inspection time.

[0044] In an optional embodiment, the moving time between multiple devices to be inspected can be estimated based on the device coordinates of the multiple devices to be inspected in the grid structure data, and the inspection time of the multiple devices to be inspected can be determined based on the device types of the multiple devices to be inspected in the grid structure data. Then, based on the moving time and the inspection time, it can be determined which devices to be inspected can be inspected within the preset inspection time, so that the inspection path can be divided into multiple inspection units according to the preset inspection time. When the inspection path is divided into multiple inspection units according to the preset inspection time, the devices to be inspected that can be inspected within the preset inspection time can be divided into the same inspection unit to ensure that there are no duplicate devices to be inspected in different inspection units, and each device to be inspected on the inspection path is included in one inspection unit.

[0045] Optionally, based on the grid structure data, the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected are determined, including: based on the device coordinates of the multiple devices to be inspected, determining the distance between two adjacent devices to be inspected; based on the distance between two adjacent devices to be inspected, determining the movement time between multiple devices to be inspected; based on the device types of the multiple devices to be inspected, determining the inspection time of the multiple devices to be inspected.

[0046] In an optional embodiment, the device coordinates of multiple devices to be inspected can be determined based on the grid structure data, and then the distance between two adjacent devices to be inspected can be determined based on the device coordinates of the multiple devices to be inspected. Then, the transportation tool used for the inspection is selected, and the moving time between the multiple devices to be inspected is determined based on the speed of the transportation tool and the distance between the two adjacent devices to be inspected. For example, if the distance between two patrol devices is short and can be reached in 10 minutes on foot, the moving time can be calculated based on a walking speed of 5 kilometers per hour. If it is not reachable in 10 minutes on foot, the moving time is calculated based on a driving speed of 30 kilometers per hour.

[0047] Based on the equipment types of multiple devices to be inspected in the grid structure data, the inspection duration of the same equipment type is set to the same value, thereby determining the inspection duration of multiple devices to be inspected. For example, if the equipment type is a bench transformer, a box-type substation, a cable junction box, or an outdoor switch box, the inspection duration is determined to be 5 minutes; if the equipment type is a distribution station or a switch room, the inspection duration is determined to be 15 minutes.

[0048] It should be noted that the specific numerical values ​​in the above examples are only examples, and the specific numerical values ​​that can be used in actual applications are not limited to these.

[0049] Optionally, based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, the inspection path is divided using a preset inspection time to obtain multiple inspection units, including: starting from the starting point of the inspection path, according to the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, the inspection path is divided into multiple inspection units according to the preset inspection time.

[0050] The starting point of the inspection path in the above steps is the first device to be inspected in the inspection path.

[0051] In an optional embodiment, starting from the first device to be inspected in the inspection path, the devices to be inspected that can be inspected within the preset inspection time can be determined based on the movement time between the multiple devices to be inspected and the inspection time of the multiple devices to be inspected, and then the devices to be inspected that can be inspected can be divided into a patrol unit so that the patrol time required for each patrol unit is roughly the same.

[0052] Optionally, starting from the starting point of the patrol path, the patrol path is divided into multiple patrol units according to a preset patrol time based on the movement time between multiple devices to be patrolled and the patrol time of multiple devices to be patrolled, including: starting from the starting point of the patrol path, searching for a first device to be patrolled that can be patrolled within the preset patrol time based on the movement time between multiple devices to be patrolled and the patrol time of multiple devices to be patrolled; constructing a target patrol unit based on the first device to be patrolled; determining a first device to be patrolled from other devices to be patrolled on the patrol path except the first device to be patrolled; starting from the first device to be patrolled, repeatedly executing the steps of searching for the first device to be patrolled that can be patrolled within the preset patrol time based on the movement time between multiple devices to be patrolled and the patrol time of multiple devices to be patrolled, and constructing a target patrol unit based on the first device to be patrolled, until there is no device to be queried on the patrol path; summarizing the target patrol units to obtain multiple patrol units.

[0053] The first device to be inspected in the above steps is found according to the arrangement order of the devices to be inspected on the inspection path, and is the device to be inspected that can be inspected within the preset inspection time.

[0054] The target inspection unit in the above steps is an inspection unit including the first equipment to be inspected that can be inspected within a preset inspection time.

[0055] In an optional embodiment, the search starts from the first device to be inspected in the patrol path, and according to the arrangement order of the devices to be inspected on the patrol path, the movement time between multiple devices to be inspected, and the patrol time of multiple devices to be inspected, the device to be inspected that can complete the patrol within the preset patrol time is determined, and it is used as the first patrol device, and then the patrol unit formed by the first patrol device is used as the target patrol unit.

[0056] Then, starting from the first device to be inspected among the remaining devices to be inspected, the device to be inspected that can be inspected within the preset inspection time is determined according to the arrangement order of the devices to be inspected on the inspection path, the movement time between multiple devices to be inspected, and the inspection time of multiple devices to be inspected, and the device to be inspected is used as the first inspection device, and then the inspection unit formed by the first inspection device is used as the target inspection unit until all devices to be queried are included in the target inspection unit. By summarizing the target inspection units, multiple inspection units can be obtained.

[0057] For example, when dividing the target patrol unit, the patrol workload of 1 hour can be used as the division standard. According to the principle of patrolling nearby, the devices to be patrolled that can be patrolled within 1 hour are divided into one target patrol unit. If the remaining patrol workload is less than 1 hour at the end of the division, the devices to be patrolled corresponding to the remaining patrol workload are divided into one target patrol unit. In this way, the patrol path is divided into several 1-hour patrol units and 1 target patrol unit less than or equal to 1 hour.

[0058] It should be noted that the specific numerical values ​​in the above examples are only examples, and the specific numerical values ​​that can be used in actual applications are not limited to these.

[0059] Optionally, the inspection path includes: a main line path, a branch line path, and starting from the starting point of the inspection path, searching for the first device to be inspected that can be inspected within the preset inspection time based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, including: starting from the starting point of the main line path, searching for the first device to be inspected that can be inspected within the preset time based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, wherein when the branch line path is found, the device to be inspected on the branch line path is searched, and after the search is completed, the device to be inspected on the main line path is searched.

[0060] The trunk line path in the above steps is the main transmission line that carries the main power load and connects various substations and important load centers.

[0061] The branch line path in the above steps is an auxiliary transmission line branched from the main line path, which is used to connect the main line path with various load centers or auxiliary equipment.

[0062] In an optional embodiment, when determining the first device to be inspected, first search on the main line path. When encountering a branch line path, switch to the branch line path and search for the device to be inspected on the branch line path. After the search is completed, return to the main line path again and search for the device to be inspected on the main line path.

[0063] Optionally, based on the grid structure data and the status data of multiple power equipment, the inspection path is determined, including: based on the grid structure data, determining the equipment whose equipment type is a connecting switch; and determining the inspection path according to the location of the equipment whose equipment type is a connecting switch and the status data of the equipment.

[0064] The device type of the tie switch in the above steps is a switch used to connect the main line path and the branch line path, and is located at a key position in the distribution network line.

[0065] In an optional embodiment, devices of the interconnecting switch type are screened out based on the grid structure data, and their positions in the distribution network are determined. The status data of the interconnecting switch device is collected, including the operating status, electrical parameters, temperature and other information of the device. If there is an abnormality in the status data of the interconnecting switch device, the branch line path connected to the interconnecting switch device is included in the inspection path. Then, the interconnecting switch device and the power equipment on the branch line path that has been included in the inspection path are excluded, and it is determined whether the status data of other power equipment is abnormal. The other power equipment with abnormalities is included in the power equipment of the inspection path, and the trunk line path and the branch line path are determined based on the topological relationship between the power equipment.

[0066] Optionally, the three-dimensional type of the distribution network line is extracted to obtain grid structure data, including: performing graphic model analysis on the three-dimensional model of the distribution network line to extract the grid structure data.

[0067] In an optional embodiment, the geographic information data corresponding to the GIS model, including the geographic coordinates of the power equipment, etc., can be exported based on the GIS model of the distribution network line in the GIS system. The exported geographic information data is converted into graph model data, that is, the geographic coordinates are converted into nodes and edges on the graph, and the connection relationship between the power equipment is represented by the nodes and edges on the graph. The converted graph model data is parsed using graph model parsing technology to identify the topological relationship between the power equipment, including information such as the equipment name, equipment type, and the connection relationship between the equipment, and obtain the grid structure data.
