[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[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 in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0024] Figure 1 This is a flowchart of a method for inspecting distribution network lines according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0025] Step S102: Extract the three-dimensional model of the distribution network line to obtain the network structure data, wherein the network 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 can be a model that describes the characteristics of the distribution network lines. It can be a CIM (Common Information Model), a GIS (Geographic Information System) model, or a BIM (Building Information Model), but it is not limited to these.

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

[0028] In one optional embodiment, information such as the power equipment and characteristics of the distribution network line can be exported from the CIM corresponding to the distribution network line through the CIM standard interface. Then, data cleaning is performed to extract data related to the network structure, such as equipment name, equipment type, equipment geographical coordinates, and topological relationships between equipment, from the data exported from the CIM. Subsequently, the data, including equipment name, equipment type, equipment geographical coordinates, and topological relationships between equipment, are standardized to obtain the network structure data.

[0029] In another alternative 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 map model analysis technology to obtain network structure data including equipment name, equipment type, equipment geographic coordinates, and topological relationships between equipment.

[0030] Step S104: Based on the grid structure data and the status data of multiple power devices, determine the inspection path. The inspection path is used to characterize the path for inspecting multiple devices to be inspected among the multiple power devices, and the status data is used to characterize whether there are any abnormalities in the multiple power devices.

[0031] The status data in the above steps may include, but is 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 power equipment and whether there are any abnormalities in the status data of multiple power equipment, so as to improve the rationality of the inspection route.

[0033] In one optional embodiment, status data of multiple power devices can be collected, including the device's operating status, electrical parameters, temperature data, vibration data, environmental data, etc., to determine whether the device has any abnormalities. Devices with higher importance can also be identified based on the device type in the network structure data. Devices with abnormalities and devices with higher importance are designated as devices to be inspected. Then, based on the topological relationships between power devices in the network structure data, multiple paths that can cover all devices to be inspected are determined, and the shortest path is selected as the inspection path. Step S106: The inspection path is divided based on the network structure data to obtain multiple inspection units.

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

[0035] In one optional embodiment, the distance between two adjacent devices to be inspected along the inspection path is determined based on the geographical coordinates of the devices in the network structure data. Starting with the first device to be inspected at the beginning of the inspection path, devices within a preset distance are grouped into one inspection unit according to the topological relationship between the devices to be inspected along the path. Then, starting with the first device among the remaining devices to be inspected along the path, devices within a preset distance are again grouped into one inspection unit according to the topological relationship between the devices to be inspected along the path, and so on, resulting in multiple inspection units. The preset distance is a pre-set distance, which can be 5000 meters, 3000 meters, or any other distance, but is not limited to this.

[0036] In another optional embodiment, the distance between two adjacent devices to be inspected along the inspection path is determined based on the geographical coordinates of the devices in the network structure data. Then, based on the selected means of transportation and its speed, the time required to travel from one device to another adjacent device can be determined. Starting with the first device to be inspected at the beginning of the inspection path, devices that can be inspected within a preset time are grouped into one inspection unit according to the topological relationship between devices along the path. Then, starting with the first device among the remaining devices to be inspected along the path, devices that can be inspected within a preset time are grouped into another inspection unit according to the topological relationship between devices along the path, and so on, resulting in multiple inspection units. The preset time is a pre-set time, which can be 5 hours, 3 hours, or any other timeframe, but is not limited to this.

[0037] The patrol route is divided into multiple patrol units, refining the granularity of the patrol tasks. The patrol tasks along the route are further subdivided into smaller task packages, enhancing the flexibility of task assignment and scheduling. Assigning patrol tasks from different units to different staff members achieves a rational allocation of human resources. By having staff members execute patrol tasks in parallel, the overall patrol efficiency along the patrol route can be improved.

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

[0039] In one optional embodiment, the assignment of multiple inspection units can be pushed to the team leader of the inspection personnel. The team leader then uses the system to assign the inspection tasks of different inspection units to different inspection personnel, allowing different inspection personnel to perform inspections of the distribution network lines in parallel. After the inspection personnel determine the inspection unit, they begin the inspection of the unit. During the inspection, upon arriving at the location of each piece of equipment to be inspected, they check in and locate themselves using a mobile APP to ensure that the inspection personnel are on-site. When defects or potential hazards are found in the equipment to be inspected, the operating status, defects, and photos of the defects are uploaded to the system via the mobile APP. The system generates a problem list and pushes the problem list to the troubleshooting personnel, who then promptly address the defects in the line equipment to ensure the power supply reliability of the distribution network lines. When the inspection personnel finish the inspection, they archive the inspection tasks of the inspection unit via the mobile APP, achieving closed-loop management of the entire inspection task plan.

[0040] In another optional embodiment, the maintenance robot can assign inspection tasks of different inspection units to different inspection personnel according to their work schedules, ensuring a balanced workload for each inspector and generating an inspection task allocation table. The maintenance robot sends the inspection task allocation table to each inspection personnel and collects the actual inspection situation and feedback information from the personnel to adjust the allocation of inspection tasks in a timely manner and ensure the efficient conduct of the inspection work.

[0041] In this embodiment of the invention, a three-dimensional model of the distribution network line is extracted to obtain network structure data. Based on the network structure data and the status data of multiple power devices, an inspection path is determined. The status data is used to characterize whether multiple power devices are abnormal. The inspection path is divided based on the network structure data to obtain multiple inspection units. The distribution network line is then inspected according to these multiple inspection units. It is noteworthy that extracting the three-dimensional model of the distribution network line to obtain network structure data improves the efficiency of acquiring this data. Using the network structure data as the basis for determining the inspection path, and determining the inspection path based on the network structure data and the status data of multiple power devices, allows for the determination of a reasonable inspection path based on whether the power devices are abnormal and the topological relationships between them. Dividing the inspection path based on the network structure data to obtain multiple inspection units, and then inspecting the distribution network line according to these multiple inspection units, allows these multiple inspection units to be executed in parallel. By inspecting multiple inspection units in parallel, the inspection efficiency of the distribution network line is improved, thereby solving the technical problem of low inspection efficiency.

[0042] Optionally, the inspection path is divided based on the grid structure data to obtain multiple inspection units, including: determining the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected based on the grid structure data, 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; and dividing the inspection path using a preset inspection time based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected to obtain multiple inspection units.

[0043] The preset inspection time in the above steps is a pre-set time that can be preset according to the actual application situation. Here, we do not impose any restrictions on the specific value of the preset inspection time.

[0044] In one optional embodiment, the movement time between multiple devices to be inspected can be estimated based on the device coordinates in the grid structure data, and the inspection time of multiple devices to be inspected can be determined based on their device types in the grid structure data. Then, based on the movement time and inspection time, it can be determined which devices can be inspected within a preset inspection time, thus dividing the inspection path into multiple inspection units according to the preset inspection time. When dividing the inspection path into multiple inspection units according to the preset inspection time, devices that can be inspected within the preset inspection time can be grouped into the same inspection unit, ensuring that there are no duplicate devices in different inspection units, and that each device 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: determining the distance between two adjacent devices to be inspected based on the device coordinates of multiple devices to be inspected; determining the movement time between multiple devices to be inspected based on the distance between two adjacent devices to be inspected; and determining the inspection time of multiple devices to be inspected based on the device type of multiple devices to be inspected.

[0046] In one optional embodiment, the coordinates of multiple devices to be inspected can be determined based on the grid structure data. Then, the distance between two adjacent devices can be determined based on these coordinates. Next, a vehicle for the inspection is selected, and the travel time between the devices is determined based on the vehicle's speed and the distance between adjacent devices. For example, if two devices are close enough to be reached on foot in 10 minutes, the travel time can be calculated based on a walking speed of 5 kilometers per hour. If they cannot be reached on foot in 10 minutes, the travel time can be 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 for devices with the same equipment type is set to the same value, thereby determining the inspection duration for multiple devices to be inspected. For example, if the equipment type is a platform transformer, a prefabricated 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 switch room, the inspection duration is determined to be 15 minutes.

[0048] It should be noted that the specific values ​​in the examples above are merely illustrative, and the specific 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, dividing the inspection path into multiple inspection units according to the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, and 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 one optional embodiment, starting from the first device to be inspected in the inspection path, based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, the devices to be inspected that can be inspected within a preset inspection time are determined, and then the devices to be inspected that can be inspected are divided into an inspection unit, so that each inspection unit has a roughly the same inspection time.

[0052] Optionally, starting from the beginning 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. This includes: starting from the beginning of the patrol path, finding the first device to 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 the first device to be patrolled from among the other devices to be patrolled on the patrol path besides the first device to be patrolled; starting from the first device to be patrolled, repeatedly executing the steps of finding the first device to 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 are no more devices to be patrolled on the patrol path; and summarizing the target patrol units to obtain multiple patrol units.

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

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

[0055] In one optional embodiment, starting from the first device to be inspected in the inspection path, the inspection is carried out according to the 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, to determine the devices to be inspected that can be inspected within a preset inspection time and to designate them as the first inspection device, and then the inspection unit composed of the first inspection device is designated as the target inspection unit.

[0056] Then, starting from the first device among the remaining devices to be inspected, the process continues according to the order of devices on the inspection path, the travel time between multiple devices, and the inspection time for multiple devices. Within the preset inspection time, the device that can be inspected is determined and designated as the first inspection device. The inspection unit consisting of the first inspection devices is then designated as the target inspection unit, until all devices to be inspected are included in the target inspection units. Summarizing the target inspection units yields multiple inspection units.

[0057] For example, when dividing the target inspection units, a 1-hour inspection workload can be used as the dividing standard. Following the principle of proximity, equipment that can be inspected within 1 hour is assigned to one target inspection unit. If, after the division, the remaining inspection workload is less than 1 hour, then the equipment corresponding to the remaining inspection workload is assigned to one target inspection unit. This divides the inspection path into several 1-hour intervals and one target inspection unit less than or equal to 1 hour.

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

[0059] Optionally, the inspection path includes: a main line path and a branch line path. Starting from the starting point of the inspection path, based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, the first device to be inspected that can be inspected within a preset inspection time is found. This includes: starting from the starting point of the main line path, based on the movement time between multiple devices to be inspected and the inspection time of multiple devices to be inspected, the first device to be inspected that can be inspected within a preset time is found. If a branch line path is found, the devices to be inspected on the branch line path are searched. After the search is completed, the devices to be inspected on the main line path are searched.

[0060] The main transmission lines in the above steps are the main power transmission lines that carry the main power load and connect various substations and important load centers.

[0061] The branch line path in the above steps is an auxiliary transmission line that branches off from the main line path and is used to connect the main line path with various load centers or auxiliary equipment.

[0062] In one optional embodiment, when determining the first device to be inspected, the search is first performed on the main line path. When a branch line path is encountered, the search is performed on the branch line path. After the search is completed, the search is performed again on the main line path.

[0063] Optionally, based on the grid structure data and the status data of multiple power devices, the inspection route is determined, including: based on the grid structure data, determining the equipment type as tie switch; and determining the inspection route based on the location of the equipment type as tie switch and the status data of that equipment.

[0064] The equipment type described in the above steps, the tie switch, is a switch used to connect the main line path and the branch line path, and is located in a critical position in the distribution network line.

[0065] In one optional embodiment, devices of the tie switch type are filtered based on the network structure data, and their locations in the distribution network lines are determined. Status data of the tie switch devices is collected, including operating status, electrical parameters, temperature, and other information. If the status data of the tie switch devices is abnormal, the branch line paths connected to the tie switch devices are included in the inspection path. Then, the tie switch devices and electrical equipment on the branch line paths already included in the inspection path are excluded. It is then determined whether the status data of other electrical equipment is abnormal, and other electrical equipment with abnormalities is included in the inspection path. Based on the topological relationships between the electrical equipment, the main line path and branch line paths are determined.

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

[0067] In one optional embodiment, geographic information data corresponding to the GIS model of the power distribution network lines in the GIS system can be exported, including the geographic coordinates of power equipment. The exported geographic information data is then converted into graph model data, that is, the geographic coordinates are converted into nodes and edges on the graph, which represent the connection relationships between power equipment. Graph model parsing technology is used to parse the converted graph model data, identifying the topological relationships between power equipment, including equipment names, equipment types, and connection relationships between equipment, thus obtaining the network structure data.
