Description

Technical Field

[0001] This invention belongs to the field of nuclear power technology, specifically relating to a method and apparatus for structuring digital maintenance procedures for nuclear power plants. Background Technology

[0002] Nuclear power plant maintenance procedures are mandatory documents that guide maintenance personnel in equipment maintenance, testing, and troubleshooting. Currently, the vast majority of these procedures exist in paper or static electronic document (such as PDF or Word) format. This format has several drawbacks: 1. Unstructured: The content of the procedures consists of plain text and images, which computers cannot understand in terms of semantic logic, making it difficult to automate and intelligently process.

[0003] 2. High risk of human error: The operation steps rely entirely on human reading and execution, which can easily lead to risks such as skipping steps, missing steps, and misreading.

[0004] 3. Information silos: Poor correlation between procedures and equipment information, historical data, drawings and manuals, etc., requires maintenance personnel to search for information across multiple systems, resulting in low efficiency.

[0005] 4. Complex version management: Upgrading or changing the version of the procedure requires manual verification and distribution, which may lead to the risk of using the old version of the procedure on site.

[0006] 5. Difficulty in accumulating experience: Best practices and modification suggestions during the maintenance process cannot be directly fed back and structured into the procedures.

[0007] Therefore, there is an urgent need to improve the management quality and utilization efficiency of maintenance procedures. Summary of the Invention

[0008] To overcome the problems existing in related technologies, a structured method and device for digital maintenance procedures in nuclear power plants are provided.

[0009] According to one aspect of the present disclosure, a method for structuring digital maintenance procedures in a nuclear power plant is provided, the method comprising: Step 1: Construct a multi-type data storage system. Establish a centralized data warehouse for terminal devices to store and manage various types of data related to maintenance procedures. Step 2: Create a procedure flow diagram. The terminal device displays the interactive interface of the graphical flow diagram editor. In the interactive interface, you can drag and drop preset nodes to define the structured attribute set of each node to build a flow diagram that represents the execution logic of the maintenance procedure. Nodes are used to represent operation steps, and the attribute set of a node is used to represent all data associations to complete the node. Step 3: Generate and store digital procedure objects. The terminal device serializes the completed flow diagram into a machine-readable standardized format file to form digital procedure objects and stores them in the procedure database. Step 4: Execution of maintenance procedures. The terminal device sends the associated digital maintenance procedure object to the mobile terminal associated with the maintenance work order based on the received maintenance work order. This allows the mobile terminal to load and parse the received digital maintenance procedure object and guide the maintenance personnel to execute the procedure according to the execution logic in the interactive interface of the mobile terminal. Step 5, Maintenance Procedure Feedback: The terminal device receives the feedback data returned by the mobile terminal and writes it back to the procedure database to bind to the corresponding digital procedure object. The feedback data is used to represent the actual execution result, time, and operator information of each step.

[0010] In one possible implementation, the data warehouse includes: equipment data, including equipment codes, models, and technical parameters from EAM, EPM, and ERP systems; knowledge data, including structured documents and knowledge graphs from drawings, manuals, and technical standards; resource data, including tools, spare parts, and personnel qualification information; and environmental data, including regional environmental information such as radiation dose rate, temperature, and humidity.

[0011] In one possible implementation, the node types include: start node, used to indicate the starting point of the procedure; end node, used to indicate the ending point of the procedure; operation node, used to indicate the action of maintenance operation, which is the basic unit of the flow graph; judgment node, used to indicate logical judgment conditions, which lead to different branch paths according to the judgment result; parallel node, used to indicate the starting point or merging point of multiple operation sequences that can be executed simultaneously; and sub-procedure node, used to indicate the call to another structured procedure, realizing the modularization of the procedure.

[0012] In one possible implementation, the node's attribute set includes: a core description, used to describe the operation content or judgment conditions of the corresponding node's operation steps in a standardized language; a data association interface, used to configure the address, query statement, or API call parameters of the data associated with the corresponding node in the multi-type data storage system; expected results / judgment criteria, used to define the criteria for the successful execution of the corresponding node's operation steps or the condition thresholds for judging each branch in the node; risk warnings, associated with the potential risks and safety measures of the corresponding node's operation steps; and required resources, used to associate with the tools, spare parts, and personnel skill requirements required for the corresponding steps.

[0013] In one possible implementation, the feedback data also includes: experience of successful execution of operation steps or reasons for failure of operation steps. The reasons for failure of operation steps are formatted input patterns. The terminal device can statistically analyze and display the effective execution rate of each step of the procedure based on the execution feedback data, and statistically analyze and display the potential defects that cause the procedure steps to fail based on the reasons for failure.

[0014] According to another aspect of the present disclosure, a structured digital maintenance procedure device for nuclear power plants is provided, the device comprising: The building module is used to establish a centralized data warehouse for storing and managing various types of data related to maintenance procedures; The creation module is used to display the interactive interface of the graphical flowchart editor. In the interactive interface, you can drag and drop preset nodes and define the structured attribute set of each node to build a flowchart that represents the execution logic of the maintenance procedure. Nodes are used to represent operation steps, and the attribute set of a node is used to represent all data associations to complete the node. The generation module is used to serialize the completed flow diagram into a machine-readable standardized format file to form a digital procedure object and store it in the procedure database. The execution module is used to send the associated digital maintenance procedure object to the mobile terminal associated with the maintenance work order based on the received maintenance work order. This allows the mobile terminal to load and parse the received digital maintenance procedure object, and guide the maintenance personnel to execute the procedure according to the execution logic in the interactive interface of the mobile terminal. The feedback module is used to receive feedback data returned by the mobile terminal and write it back to the procedure database to bind to the corresponding digital procedure object. The feedback data is used to represent the actual execution result, time, and operator information of each step.

[0015] According to another aspect of the present disclosure, a structured digital maintenance procedure device for nuclear power plants is provided, the device comprising: processor; Memory used to store processor-executable instructions; The processor is configured to execute the above-described method.

[0016] According to another aspect of the present disclosure, a non-volatile computer-readable storage medium is provided, on which computer program instructions are stored, which, when executed by a processor, implement the above-described method.

[0017] The beneficial effects of this disclosure are as follows: The structuring method for digital maintenance procedures in nuclear power plants provided by this disclosure transforms maintenance procedures described in natural language into structured procedure flowcharts through a visual flowchart editing method. Each step is dynamically associated with relevant data in multiple types of data storage systems, forming a seamless set of diverse data. Ultimately, a digital procedure object that can be parsed and executed by a computer is generated. Compared to some existing digital solutions that attempt to use forms or simple templates to input procedures, this disclosure fundamentally solves the problem of expressing the inherent logic of procedures (such as branches, loops, parallelism, and jumps), effectively integrating multi-source heterogeneous data. The method of this disclosure has a user-friendly interface and is easy to operate. During the procedure creation process, it also helps to clearly organize maintenance procedures, laying the foundation for subsequent intelligent applications (such as AR guidance, AI-assisted decision-making, and automated work orders).

[0018] Figure 1 This is a flowchart illustrating a structured method for digital maintenance procedures in nuclear power plants, as shown in an embodiment of this disclosure.

[0019] Figure 2 This is a block diagram of a structured device for digital maintenance procedures in a nuclear power plant, as shown in an embodiment of this disclosure. Detailed Implementation

[0020] The present disclosure will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Unless otherwise defined, the technical and scientific terms used in this disclosure have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains; the terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure; the term "comprising" and any variations thereof in this disclosure are intended to cover non-exclusive inclusion. Clearly, the embodiments described in this disclosure are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0022] In this disclosure, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in one embodiment of this disclosure. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] Figure 1This is a flowchart illustrating a structured method for digital maintenance procedures in nuclear power plants, as shown in an embodiment of this disclosure. This method can be executed by a terminal device, which can be a server, desktop computer, laptop computer, etc. This embodiment of the disclosure does not limit the type of terminal device. Figure 1 As shown, the method includes: Step 1: Construct a multi-type data storage system and establish a centralized data warehouse to store and manage various types of data related to maintenance procedures. The data warehouse includes: equipment data, including equipment codes, models, and technical parameters from EAM (Enterprise Asset Management), EPM (Enterprise Performance Management), and ERP (Enterprise Resource Planning) systems; knowledge data, including structured documents and knowledge graphs from drawings, manuals, and technical standards; resource data, including tools, spare parts, and personnel qualification information; and environmental data, including regional environmental information such as radiation dose rate, temperature, and humidity.

[0024] Step 2: Create a procedure flow graph. The graphical flow graph editor's interactive interface allows users to drag and drop preset nodes to define the structured attribute set of each node (operation node, decision node, etc.) to construct a flow graph representing the execution logic of the maintenance procedure. Nodes represent operation steps, and their attribute sets represent the content and resources required to complete those steps. Node types include: start nodes (representing the beginning of the procedure); end nodes (representing the end of the procedure); operation nodes (representing the actions of maintenance operations and serving as the basic unit of the flow graph); decision nodes (representing logical judgment conditions, leading to different branch paths based on the judgment result); parallel nodes (representing the starting point or convergence point of multiple simultaneously executable operation sequences); and sub-procedure nodes (representing calls to another structured procedure, enabling modularization of the procedure).

[0025] The node's attribute set includes: a core description, used to describe the operation content or judgment conditions of the corresponding node's operation steps in a standardized language; a data association interface, used to configure the address, query statement, or API call parameters of the data associated with the corresponding node in the multi-type data storage system; expected results / judgment criteria, used to define the criteria for the successful execution of the corresponding node's operation steps or the condition thresholds for judging each branch in the node; risk warnings, associated with the potential risks (such as high radiation, high pressure) and safety measures of the corresponding node's operation steps; and required resources, associated with the tools, spare parts, and personnel skill requirements of the corresponding steps.

[0026] Step 3: Generate and store digital procedure objects. Serialize the completed flow diagram into a machine-readable standardized format file (such as JSON or XML) to form digital procedure objects and store them in the procedure database. The digital procedure object fully preserves the execution logic of the procedure and all data associations.

[0027] Step 4: Maintenance Procedure Execution. After receiving a maintenance work order, the terminal device parses the work order to obtain the associated digital maintenance procedure. This digital maintenance procedure object is then sent to the mobile terminal associated with the work order. The mobile terminal loads and parses the received digital maintenance procedure object, guiding the maintenance personnel to execute the procedure according to its execution logic within the mobile terminal's interface. During the execution of the digital maintenance procedure object, the mobile terminal: retrieves and displays relevant data from multiple data storage systems through the data association interface of each node; records the actual execution results, time, operator information, tips for successful execution, or reasons for failure for each step; and generates execution feedback data.

[0028] Step 5: Maintenance Procedure Feedback. The terminal device receives feedback data from the mobile terminal and writes it back to the procedure database, binding it to the corresponding digital procedure object for continuous procedure optimization and experience accumulation. For example, if the reason for the failure of an operation step is in formatted input mode, the maintenance personnel can enter the reason for the failure by selecting a method. The terminal device can statistically analyze and display the effective execution rate of each step of the procedure based on the execution feedback data, and can also statistically analyze and display the potential defects that led to the failure of the procedure steps based on the reasons for the failure, assisting in the continuous optimization of the procedure. During the execution of the procedure, maintenance personnel can also refer to the experience of successful execution of the corresponding operation steps or the reasons for failure, thereby providing timely technical guidance and risk avoidance to maintenance personnel on-site, effectively improving maintenance quality and efficiency.

[0029] The structuring method for digital maintenance procedures in nuclear power plants disclosed herein offers the following advantages: Visualization and ease of use: Complex logic is intuitively displayed through a flow diagram editor, lowering the barrier to procedure structuring. Machine executable: The generated digital procedure objects can be parsed by computers, enabling automated execution and intelligent guidance. Deep data integration: Information silos are broken down through node data association interfaces, allowing procedure steps to automatically retrieve relevant information within the context. Strong consistency: The integrity and accuracy of the procedure logic are ensured, reducing human error. Traceability and optimizability: Execution data is recorded throughout the process, providing a data foundation for procedure version management, performance analysis, and continuous improvement.

[0030] In one possible implementation, a structured device for digital maintenance procedures in nuclear power plants is provided, the device comprising: The building module is used to establish a centralized data warehouse for storing and managing various types of data related to maintenance procedures; The creation module is used to display the interactive interface of the graphical flowchart editor. In the interactive interface, you can drag and drop preset nodes and define the structured attribute set of each node to build a flowchart that represents the execution logic of the maintenance procedure. Nodes are used to represent operation steps, and the attribute set of a node is used to represent all data associations to complete the node. The generation module is used to serialize the completed flow diagram into a machine-readable standardized format file to form a digital procedure object and store it in the procedure database. The execution module is used to send the associated digital maintenance procedure object to the mobile terminal associated with the maintenance work order based on the received maintenance work order. This allows the mobile terminal to load and parse the received digital maintenance procedure object, and guide the maintenance personnel to execute the procedure according to the execution logic in the interactive interface of the mobile terminal. The feedback module is used to receive feedback data returned by the mobile terminal and write it back to the procedure database to bind to the corresponding digital procedure object. The feedback data is used to represent the actual execution result, time, and operator information of each step.
