Description

Technical Field

[0001] This invention relates to the field of power distribution automation technology, and in particular to an intelligent operation and maintenance system for power distribution automation terminals based on the metaverse. Background Technology

[0002] Distribution automation is based on the primary network structure and equipment of the distribution network, and comprehensively utilizes computer technology, information and communication technologies to achieve monitoring, control and operation management of the distribution network. Distribution terminals are distribution automation terminal units, a general term for various remote monitoring and control units installed in the distribution network, mainly including DTUs, FTUs, TTUs, fault indicators, etc. Their main function is to collect operating data or fault information of distribution equipment and remotely control it.

[0003] Distribution automation terminals are a general term for various remote monitoring and control units installed in the distribution network. When a distribution automation terminal malfunctions, the traditional troubleshooting process involves on-site inspection by maintenance personnel, fault location, and fault handling to eliminate distribution network operation problems and improve power supply reliability. However, medium and low voltage distribution networks have a large number of devices, and distribution terminals objectively suffer from inconsistent equipment quality and harsh operating conditions, resulting in a high failure rate. After a large number of distribution terminals are put into operation, the workload for operation and maintenance is enormous. How to effectively connect a large number of distribution terminals and reduce maintenance workload has always been a major challenge hindering the development of distribution automation.

[0004] The operating environment of distribution terminals is complex and variable. Under certain extreme conditions, the distribution automation master station may fail to collect information from the distribution terminals, such as power outages in the distribution terminal communication modules or abnormal exits of the distribution master station's front-end data acquisition program. This can affect the monitoring and operation management of the distribution network. Traditional maintenance of distribution automation terminals relies on on-site inspections by personnel, which delays the troubleshooting time of the distribution automation terminals and affects the stable operation of distribution automation.

[0005] The "metaverse" is a deep fusion of the virtual and the real. The metaverse is a "digital twin" world built using mature digital technologies that is both based on and independent of the real world. The metaverse provides users with sensory stimulation through wearable devices that offer visual, auditory, tactile, and full-body sensory experiences, as well as low-latency and highly realistic interactive technologies. This helps improve the quality of online interaction and communication in the metaverse and achieves an immersive experience for users. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent operation and maintenance system for power distribution automation terminals based on the metaverse, so as to solve the problems mentioned in the background art.

[0007] This invention is achieved through the following technical solution: a power distribution automation terminal intelligent operation and maintenance system based on a metaverse. The system establishes a power distribution automation terminal operation and maintenance system within the metaverse, and performs intelligent analysis and decision support for the operation and maintenance terminals, evaluates and classifies the skill levels of operation and maintenance personnel. The power distribution automation terminal operation and maintenance system includes a device layer, an IoT management layer, a virtual reality layer, an intelligent analysis layer, and a visualization layer.

[0008] The device layer is used to access and collect data from primary distribution network equipment, secondary distribution network equipment, AR / VR devices, smart wearable devices, field environmental sensor devices, and numerical weather forecasting devices.

[0009] The IoT management layer is used to manage the communication protocols, communication networks, and geographic information systems (GIS) of the devices used.

[0010] The virtual reality layer is used to model primary equipment such as distribution network lines and distribution transformers, as well as secondary equipment such as power distribution terminals, to model the operation and maintenance personnel of distribution network terminals, and to model the operating environment of distribution transformer terminals.

[0011] The intelligent analysis layer is used for remote operation and maintenance of operation and maintenance terminals, intelligent analysis and assistance, and profiling and analysis of operation and maintenance terminals and operation and maintenance personnel.

[0012] The visualization layer is used to visualize the operating status and failure rate of primary equipment in the distribution network, the operating status, failure rate, and causes of failure of secondary equipment in the distribution network, the work of maintenance personnel, the operating environment of distribution terminals, and the effectiveness of remote maintenance of distribution terminals.

[0013] Optionally, the modeling includes information modeling and virtual reality modeling. The parameters required for information modeling include, but are not limited to, the identity characteristics of maintenance personnel, equipment ledger, access location, association with primary equipment, operating voltage level, sampling point name, data type, collection cycle, digital certificate, software version, operating environment, operating protocol, communication cycle, and other information based on the terminal model information in PMS and the maintenance needs of the power distribution terminal.

[0014] The virtual reality modeling includes visual modeling of the physical appearance of the device.

[0015] Optionally, it also includes a mobile IoT terminal, which can access the intelligent operation and maintenance metaverse system of power distribution automation terminals, interact with the location information of operation and maintenance personnel in real time, access and obtain information of power distribution automation terminals, receive operation and maintenance task assignments, accept operation and maintenance auxiliary decision-making suggestions, complete operation and maintenance tasks, record operation and maintenance logs, and evaluate operation and maintenance effectiveness.

[0016] Optionally, remote operation and maintenance can be performed on the operation and maintenance terminal, which includes: remotely distributing configuration files to the operation and maintenance terminal, performing digital upgrade management on the operation and maintenance terminal, and actively supplementing and completing the data of the operation and maintenance terminal.

[0017] Optionally, if remote maintenance of the maintenance terminal fails or partially fails, the system switches to manual on-site maintenance. Based on information such as the matching degree of maintenance personnel, the difficulty of maintenance tasks, the workload of maintenance personnel, and the distance of maintenance personnel from the equipment, the system pushes on-site maintenance tasks. The system uses a bidding mode or the optimal assignment mode to select suitable maintenance personnel, provides real-scene navigation, and guides the maintenance personnel to perform on-site maintenance.

[0018] Optionally, before maintenance personnel go to the maintenance location, the Metaverse system provides them with an on-site maintenance case library and a real-world display of power distribution terminals. It can confirm the equipment maintenance status based on mobile IoT terminals and upload maintenance operation videos and maintenance test logs to Metaverse through mobile IoT terminals.

[0035] The intelligent operation and maintenance system for distribution automation terminals based on the metaverse disclosed in this application establishes an operation and maintenance system for distribution automation terminals in the metaverse. It performs enhanced virtual reality modeling of the location, physical appearance, and model information of distribution terminals, and performs intelligent analysis and auxiliary decision-making for online operation and maintenance in the metaverse.

[0039] Specifically, remote operation and maintenance of the operation and maintenance terminal includes: remotely distributing configuration files to the operation and maintenance terminal, digitally upgrading and managing the operation and maintenance terminal, and proactively supplementing and completing the data of the operation and maintenance terminal.

[0040] (1) Remote maintenance of distribution transformer terminal model: A remote operation and maintenance mark is set on the equipment metaverse icon based on geographic information system. The metaverse system obtains distribution transformer terminal model information from the equipment operation and maintenance lean management system (PMS), including but not limited to equipment ledger, access location, association with primary equipment, operating voltage level, sampling point name, data type, collection cycle, etc. The model is based on the terminal model information in PMS and the information required for distribution terminal operation and maintenance, including but not limited to digital certificate, software version, operating environment, operating protocol, communication cycle, etc. The distribution automation terminal intelligent operation and maintenance metaverse system performs virtual reality modeling of equipment and visualizes information such as model update time, update content, and whether the update is successful. Distribution terminal managers and remote operation and maintenance personnel can quickly identify the equipment update status, update content, and whether the update is successful from the metaverse system. Once the update fails, an alarm message is displayed in the system and relevant alarm messages are pushed to the surrounding operation and maintenance personnel. The operation and maintenance personnel receive the alarm message and can view the update process and failure content in the metaverse system to prepare for on-site operation and maintenance.

[0041] (2) Remotely distribute configuration files, characterized in that the metaverse establishes a multi-channel operation and maintenance system, including a terminal business channel, an operation and maintenance channel and an emergency backup channel. The metaverse system realizes communication of conventional four remote data through the business channel and visualizes the channel status within the metaverse system. The operation and maintenance channel and the emergency backup channel adopt custom protocols and use broadcast mode to realize the batch management of terminals by the metaverse system. The metaverse system listens to the registration information of the power distribution terminal through the listening port and performs digital identity verification with the terminal in an encrypted manner.

After the communication is restored, the terminal device uploads the historical data, the metaverse system parses the relevant data, completes the historical data integrity verification function, and can manually or automatically replace and complete the data that is inconsistent between the time series library and the terminal.

[0044] Optionally, if remote maintenance of the maintenance terminal fails or partially fails, the system switches to manual on-site maintenance. Based on information such as the matching degree of maintenance personnel, the difficulty of maintenance tasks, the workload of maintenance personnel, and the distance of maintenance personnel from the equipment, the system pushes on-site maintenance tasks. The system uses a bidding mode or the optimal assignment mode to select suitable maintenance personnel, provides real-scene navigation, and guides the maintenance personnel to perform on-site maintenance.

[0045] Specifically, maintenance personnel receive maintenance tasks and proceed to the terminal site to conduct on-site maintenance. Before the personnel arrive at the maintenance location, the Metaverse system provides them with a local maintenance case library and a real-world display of the power distribution terminal, improving their preparation efficiency. They confirm the equipment's maintenance status using mobile IoT terminals, conduct maintenance debugging, and upload maintenance operation videos and test logs to Metaverse via these terminals. Maintenance personnel can also use mobile IoT terminals to remotely request assistance and receive guidance from other maintenance personnel. Maintenance administrators can monitor the on-site operations of maintenance personnel in real time within the Metaverse system and provide necessary instructions. After maintenance is completed, the maintenance personnel confirm the completion status, thus concluding the maintenance process.

[0046] Specifically, the system provides intelligent analysis and assistance to the maintenance terminals. This includes: the intelligent analysis layer identifies maintenance issues uploaded by the maintenance terminals based on logs, updates and improves its own knowledge base, and automatically prompts maintenance personnel with the cause and solution when the same problem is encountered again during maintenance, and plays maintenance recordings.

[0047] Furthermore, the system includes functions such as statistical analysis, fault ranking, and quantitative scoring of on-site equipment malfunctions. This enables the monitoring and quantification of product faults across different manufacturers and batches, and provides early warnings for equipment and manufacturers with high fault rates. Simultaneously, it identifies typical / frequent fault categories and comprehensively displays and assists in the analysis of fault categories, operating condition data, and operating environment data. Through data mining, it analyzes the correlations between data to explore the connection and relationship between typical / frequent fault categories and the operating environment, summarizes the relationship between typical fault occurrence rates and the environment, and, combined with on-site survey findings, guides the implementation of on-site processes for distribution network terminal equipment and product processes from equipment manufacturers for specific environments.
