Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of map path planning, and more specifically, to a converter station auxiliary space map path planning method based on SLAM. Background Art
[0002] As an important component of the power system, converter stations are widely used in high-voltage direct current transmission systems. Their main function is to convert AC into DC, or DC into AC, and connect to the grid through converters to ensure the transmission and distribution of electricity. The operation and maintenance of converter stations are crucial to the stability and reliability of the power system, so regular maintenance and inspection are indispensable. In modern converter stations, the equipment is diverse and complex, and maintenance tasks usually require inspectors to adopt different maintenance strategies according to the different conditions of the equipment to ensure that the equipment operates in the best condition.
[0003] During the maintenance and inspection process of the converter station, AR glasses can display the status of the equipment in real time, provide path planning information, and effectively assist operators in making quick decisions. With AR glasses, users can overlay digital information in their field of vision, making AR glasses an important tool for on-site operation guidance, data visualization, and information feedback. However, traditional path planning and task management methods have difficulty dealing with complex equipment layouts, task priorities, and conflicts in maintenance time. Therefore, it is particularly important to combine the intelligent assistance of AR glasses with efficient path planning technology.
[0004] Existing path planning systems usually rely on static preset schemes or simple algorithms, and lack dynamic task scheduling and conflict management. These traditional systems cannot flexibly respond to changes in equipment status and the need for multi-task parallel processing when faced with real-time and complex converter station environments. Especially in environments with complex equipment layouts and complicated maintenance tasks, traditional systems cannot effectively handle task priorities, estimated processing times, and possible conflicts between tasks, resulting in maintenance personnel encountering unnecessary path overlaps or time waste when performing tasks. In addition, traditional systems provide limited support for operators, lack real-time information feedback and dynamic adjustment functions, and often fail to respond to on-site changes in a timely manner. Therefore, existing maintenance and inspection path planning solutions have obvious limitations when faced with complex and dynamic working environments.
[0005] Therefore, the present invention proposes a converter station auxiliary space map path planning method based on SLAM to solve the above problems. Summary of the invention

S2. Use The algorithm performs path search and calculates the actual path cost g(n) and heuristic cost h(n) of each task. The heuristic cost h(n) is comprehensively evaluated by the task priority, estimated processing time and conflict with other tasks, and conflicts are avoided through conflict penalty items. The calculation formula of h(n) is: ; Among them, wpriority is the weight coefficient of task priority Pn, wtime is the weight coefficient of expected processing time Tn, n is task n, m is task m, α is the conflict penalty coefficient, and Conflicting is a set of conflicting tasks; S3, evaluate the optimal path based on the path cost and heuristic cost of the task to avoid conflicts between tasks; S4: Output the processing sequence and corresponding start and end time of maintenance / inspection tasks, and provide real-time path feedback to operators through AR glasses to guide the task execution sequence and coordination between tasks; S5. Use AR glasses to display path planning results, task execution progress, and suggestions for dynamically adjusting the task sequence to ensure smooth task execution and respond to environmental changes.

BRIEF DESCRIPTION OF THE DRAWINGS
[0021] Figure 1 It is a module schematic diagram of the converter station management system in the present invention. DETAILED DESCRIPTION
[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0024] See also Figure 1 , the present invention provides the following technical solutions: Embodiment 1, a converter station auxiliary space map path planning method based on SLAM, comprises the following steps: S1. The converter station management system is connected to the AR glasses through the WAPI protocol. The converter station management system uses SLAM technology to build a real-time map of the converter station's spatial environment and sets task priorities, estimated processing time and locations for multiple maintenance / inspection tasks based on map data. It should be noted that through the WAPI protocol, AR glasses can exchange real-time data with the converter station management system and ensure that operators can obtain instant task information and spatial feedback. The converter station management system uses spatial data for task scheduling and path planning, and combines augmented reality technology (AR) to provide real-time operation guidance for inspection personnel.
[0025] S2. Use The algorithm performs path search and calculates the actual path cost g(n) and heuristic cost h(n) of each task. The heuristic cost h(n) is comprehensively evaluated by the task priority, estimated processing time and conflict with other tasks, and conflicts are avoided through conflict penalty items. The calculation formula of h(n) is: ; in, , are the weight coefficients of task priority Pn and estimated processing time Tn, n is task n, m is task m, α is the conflict penalty coefficient, and Conflicting is a set of conflicting tasks. These weight coefficients are used for dynamic adjustment to balance the impact of task priority and time, ensuring that path planning will not cause unnecessary delays due to long task processing time while meeting task priority. The setting of weight coefficients depends on the nature of the task and actual needs, and can be dynamically adjusted according to the actual scenario.
[0026] Pn is the priority of task n. Each task is assigned a priority value based on its importance and urgency. Tasks with high priority need to be processed first.
[0027] Tn is the estimated processing time of task n (this estimated processing time is predicted based on the average time previously required for task n). This value represents the time required to complete a task and is used to assess the impact of a task on the total working time. The longer the estimated processing time, the greater the disruption of the task to the overall scheduling.
[0028] The purpose of designing the heuristic cost h(n) is to ensure that in the task planning process, high-priority tasks that require a shorter time to complete are given priority, while avoiding conflicts between tasks. By introducing conflict penalty items, the system can automatically avoid situations where tasks overlap for too long, avoid task conflicts and resource waste in the system, and improve the efficiency and accuracy of task execution.
[0029] S3, evaluate the optimal path based on the path cost and heuristic cost of the task to avoid conflicts between tasks; S4: Output the processing sequence and corresponding start and end time of maintenance / inspection tasks, and provide real-time path feedback to operators through AR glasses to guide the task execution sequence and coordination between tasks; S5. Use AR glasses to display path planning results, task execution progress, and suggestions for dynamically adjusting the task sequence to ensure smooth task execution and respond to environmental changes.
[0030] Specifically, in the heuristic cost h(n), the weight coefficient of the task priority Pn is and the weight coefficient of the estimated processing time Tn It can be dynamically adjusted according to the nature of the task to balance the impact of priority and time according to actual needs; specifically, the adjustment of the weight coefficients of the task priority Pn and the estimated processing time Tn should take into account the urgency and importance of the task, the risk of equipment failure, and changes in the working environment. For example, in emergency maintenance tasks, higher priorities may require larger weight coefficients to ensure that the task can be executed first; while in general regular inspections, the estimated processing time Tn of the task may occupy a larger weight to optimize the overall working time and path planning efficiency. By dynamically adjusting these weight coefficients, the path planning system can respond to various maintenance tasks more flexibly, ensuring efficient completion of task scheduling in complex environments, thereby achieving the best execution order and shortest execution time of tasks.
[0031] In the heuristic cost h(n), Indicates the time overlap between task n and task m. When two tasks are being executed, their start and end times overlap, and The calculation formula is: ; When among them, is the start time of task n, is the end time of task n, is the start time of task m, is the end time of task m. Overlapping time usually means that task n and task m need to share the same resources (such as people, equipment, space, etc.). If these tasks are carried out at the same time, they may cause conflicts, resulting in reduced efficiency or delays.
[0032] Furthermore, the conflict penalty between tasks The calculation formula is: ; in, is the conflict penalty coefficient, which quantifies the negative impact of the overlap time. is the overlap time between task n and task m, and is an important measure of the time conflict between tasks. It helps the path planning algorithm identify and avoid overlaps between tasks when optimizing task scheduling to ensure efficient and conflict-free task execution order.
[0033] In this embodiment, a converter station auxiliary space map path planning method based on SLAM is implemented by connecting a converter station management system with AR glasses, wherein the converter station management system includes: Task management module, used to set the priority, estimated processing time and location of multiple maintenance / inspection tasks, and dynamically adjust the task priority weight coefficient and processing time weight coefficient to meet the balance requirements between task priorities and time; Path search module, based on The algorithm calculates the path cost g(n) and heuristic cost h(n) of each task and generates the optimal path; The monitoring module is used to monitor the progress of maintenance / inspection tasks in real time to ensure that the tasks are executed as planned. If the task progress is found to be lagging behind or abnormal, the task sequence and path will be automatically adjusted; Output module: The output module is used to output the task planning results, path information and task execution instructions to the operator's AR glasses, so that the operator can provide real-time guidance and execute tasks; The map update module is used to update the spatial map of the converter station in real time and provide real-time spatial information to operators through AR glasses to ensure the accuracy of path planning and task execution.
[0034] The map update module uses SLAM technology to scan and model the space environment of the converter station in real time, build a dynamic space map of the converter station, and update the space map in real time according to the changes in equipment and environment during the task execution, ensuring that changes in the task path and equipment status can be reflected in the map in a timely manner. After the map update module provides space map updates, the path search module replans the task path to ensure that the task execution is not affected by environmental changes, and provides new path guidance through AR glasses.
[0035] Specifically, the path search module includes: The task information receiving unit is used to receive and store the priority, estimated processing time, location and conflict information between multiple maintenance / inspection tasks from the task management module; through the effective storage and organization of this information, the task information receiving unit can provide accurate data support for subsequent path planning and optimization, ensuring the efficient operation of the task management system.
[0036] The path cost calculation unit is used to calculate the actual path cost g(n) of each task. The path cost is calculated by the distance between the spatial map built based on SLAM technology and the current position of the task. The shortest path algorithm is used to estimate the spatial distance between tasks. The heuristic cost calculation unit is used to calculate the heuristic cost h(n) based on the task priority, estimated processing time and conflict information with other tasks; the calculation of the heuristic cost not only takes into account the characteristics of the task itself, but also makes adjustments based on the conflict between tasks to ensure the rationality and efficiency of task scheduling.
[0037] The path search unit is used to perform A* algorithm path search based on the calculated path cost g(n) and heuristic cost h(n), evaluate the optimal execution path for each task, and optimize the task execution order based on the priority, processing time and conflict between tasks; optimize the execution order of tasks, avoid conflicts between tasks, and improve the efficiency and accuracy of path planning. This process ensures the rationality of the task execution order, effectively reduces the overlap and conflict between tasks, and improves the execution efficiency of tasks.
[0038] The conflict detection unit is used to detect and identify conflicts between tasks in real time, especially during the path planning process, to avoid task overlap or path conflicts and ensure smooth execution of tasks. If a conflict is detected, the system will make adjustments, automatically replan the path or adjust the order of task execution to avoid interference between tasks and waste of resources, thereby ensuring the smooth completion of the task.
[0039] The path feedback unit is used to output the optimized task path and task sequence to the control system and provide it to the operator's AR glasses to ensure that the operator performs the task according to the path recommended by the system. Through AR glasses, operators can obtain real-time guidance on path planning on site, and the system can overlay digital path information in the operator's field of view, clearly marking the start and end positions and execution order of each task. This real-time path feedback can help operators quickly understand the overall picture of task execution, effectively reduce operational errors, improve task execution efficiency, and minimize time waste and resource competition caused by path conflicts.
[0040] Specifically, the monitoring module includes: Task status collection unit, used to collect the current status information of maintenance / inspection tasks, including task progress, execution time, equipment status and potential conflicts; Real-time monitoring unit, used to track the progress of task execution in real time, check whether the task is executed according to the predetermined plan, and monitor possible delays or progress lags; Anomaly detection unit, used to detect abnormal situations that may occur during task execution, such as equipment failure, time conflict, etc., and generate alarm information; The task adjustment unit is used to automatically adjust the task sequence, path planning and execution time when an exception occurs during the task execution process to ensure that the task continues to be executed according to the plan or optimized plan; The data feedback unit is used to feed back task status information, progress reports and abnormal situations to the task scheduling system, and display status information to the operator's AR glasses in real time to ensure that the operator receives real-time feedback and guidance.
[0041] The data feedback unit displays status information to the AR glasses, including the current status of task execution, the execution order of scheduled tasks, conflict prompts, and path adjustment instructions.
[0042] Output modules include: The task path generation unit is used to generate the optimal path for each task based on the path planning results. The path information includes the task execution order, estimated execution time, path distance, etc. The task execution instruction generation unit generates corresponding operation instructions according to the task execution plan and guides operators to execute tasks according to task priority, schedule and path; The AR output unit is used to transmit the generated path information and task execution instructions to the AR glasses worn by the operator in real time, and provide the operator with visual path planning and task guidance through the AR glasses, including direction guidance, task execution steps and time prompts; The real-time adjustment functional unit is used to dynamically adjust the task execution order according to the status information fed back during the task execution, such as task progress, conflict conditions, etc., and update the path information and task instructions to the operator in real time through AR glasses to ensure the smooth completion of the task.
[0043] In summary, the SLAM-based converter station auxiliary space map path planning method combines SLAM technology and A* path planning algorithm, which can accurately construct the space map of the converter station and optimize the path based on task priority, estimated processing time, location and other information. By dynamically calculating the path cost and heuristic cost of each task, it can intelligently evaluate the conflicts between tasks, avoid path overlap through conflict penalty items, and ensure that tasks are executed in the optimal order. In addition, it is also possible to monitor the progress of tasks in real time, adjust path planning in time, and avoid task delays.
