Description

Technical Field

[0001] This invention belongs to the field of power secondary equipment modeling technology, specifically relating to a visual modeling and configuration system, method, equipment and medium for power secondary equipment based on external electrical signal annotation. Background Technology

[0002] In the design and engineering configuration of secondary power equipment, such as relay protection devices, measurement and control devices, and remote control devices, a comprehensive description of the equipment's physical structure and electrical connections is required. This typically involves the following core elements: the device's external geometry, the shape, dimensions, and installation location of internal components, the models and layout of various connectors, the precise physical location and numbering of each terminal on the connectors, and the types and functions of electrical signals defined by external engineering design. Furthermore, it is essential to clearly establish the accurate correspondence between terminals and these electrical signals.

[0003] However, existing working models and methods face a series of significant technical bottlenecks. First, at the geometric representation level, the geometric information of devices and their components generally exists in unstructured file formats, such as PDF drawings, CAD files, or ordinary images. These formats cannot be directly parsed and calculated by computer software, making it difficult to form structured models that can be used for automated processing. This results in the inability to perform programmed and precise positioning and identification of key components such as terminals.

[0004] Secondly, for the critical entity of physical terminals, there is a lack of a unified and standardized machine-readable representation model for its core information such as location, serial number, type, and shape. This unstructured information makes it difficult for subsequent automated design, verification, and configuration tools to directly call and utilize this data, severely hindering the automation process of the design flow.

[0005] Furthermore, the mapping between external electrical signal labels and physical terminals is highly dependent on manual operation. Signal lists generated during engineering design are often separate from terminal data provided by equipment manufacturers, requiring technicians to establish the correspondence through manual comparison and cross-checking. This method is not only inefficient and labor-intensive, but also highly susceptible to human error, and lacks an effective change tracking mechanism, thus creating potential risks to engineering safety and quality management.

[0006] A deeper problem lies in the disconnect between the concepts of "physical terminal" and "logical port" in existing technologies. A terminal merely represents its physical existence and connection point attributes on a device, while a logical port carries semantic information such as the function, direction, and electrical type of the signal. The lack of a unified modeling mechanism to organically integrate them makes automated integration from physical design to logical function implementation difficult, hindering the development of advanced applications such as automatic schematic generation and intelligent binding of communication parameters.

[0007] Furthermore, due to the lack of a reusable standardized model template library, designers often need to repeatedly draw basic geometric figures such as device frames, plates, and connectors from scratch for different types of devices or different engineering application scenarios, and perform a large amount of repetitive attribute definition work, resulting in low modeling efficiency and difficulty in ensuring the consistency of model data between different projects.

[0008] Ultimately, these deficiencies result in downstream automation systems, such as automatic diagram generation systems, IEC 61850 standard information model mapping tools, and engineering instance configuration generation systems, lacking a unified, clearly structured, and machine-readable physical model of the device as input. Each system often needs to independently parse and convert heterogeneous data from different sources, creating data silos and information islands, which become a key obstacle to achieving digital and automated design throughout the entire lifecycle of power secondary equipment. Summary of the Invention

[0009] Based on the aforementioned shortcomings and deficiencies in the prior art, one of the objectives of this invention is to at least solve one or more of the aforementioned problems in the prior art. In other words, one of the objectives of this invention is to provide a visual modeling and configuration system, method, device, and medium for power secondary equipment based on external electrical signal annotation that meets one or more of the aforementioned requirements, so as to improve the efficiency and accuracy of power secondary equipment design.

[0010] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a visual modeling and configuration system for secondary power equipment based on external electrical signal annotation, comprising: The geometric modeling module is used to build geometric models of devices, plates, connectors and terminals based on predefined parametric grid cells, and record their coordinates and hierarchical relationships, wherein the geometric model of the terminal corresponds to the pin in the physical geometric model; The physical electrical signal modeling module is used to establish a physical electrical signal model and define ports (Ports) for electrical signals in the physical electrical signal model.

The consistency verification module is used to compare and verify the association between Port, PLP, Function and their corresponding information model objects between secondary equipment from different manufacturers and / or different models based on the unified external electrical signal tag, so as to provide a consistency verification means for establishing a unified association between secondary equipment from different manufacturers and / or different models. The model export module is used to export the device model containing at least one PLP, at least one Function and their information model matching relationship into a structured file.

[0012] As a preferred option: The external electrical signal import module supports accessing external signal data through at least one of CSV, JSON, Excel, database, or REST API, and labels the imported unified external electrical signal with the corresponding Port to form the electrical signal semantics of the Port.

[0013] As a preferred option: The semantic binding module is used to semantically bind the electrical signal labeled on the Port to the corresponding PLP, and to perform rule verification on at least one of the signal type, direction, polarity, terminal and functional domain according to preset rules, wherein the binding result serves as the basis for the consistency verification module to perform correlation comparison and verification.

[0014] As a preferred option, the following also includes: The physical geometric attributes corresponding to the pin include at least one of the following: its position in the connector, board and device, terminal index number, hole size, terminal spacing and geometric position information. The electrical attributes corresponding to the Port include at least one of the following: signal type, direction, polarity, terminal, application category, and external electrical signal label; The semantic attributes corresponding to the logical layer L include at least one of the following: signal name, functional domain, loop role, connection semantics, and IEC61850 information model association identifier. The Function includes the functional organization relationship formed by the aggregation of multiple PLPs and the corresponding information model matching identifier.

[0015] As a preferred option: The Function organization module combines multiple PLPs according to the same hardware circuit, the same functional unit, the same device interface boundary, and / or the same functional purpose to form the Function.

[0016] As a preferred option: The consistency verification module, based on a unified external electrical signal label, compares the relationships between the corresponding Ports, PLPs, Functions and their corresponding objects in the IEC 61850 information model in secondary equipment from different manufacturers and / or different models, and performs consistency verification on at least one of the following: signal name, direction, functional domain, loop role, and interface semantics.

[0017] In a second aspect, the present invention provides a method for visual modeling and configuration of secondary power equipment, characterized in that it applies the system described in the first aspect and includes the following steps: S1. Based on predefined parametric grid units, establish geometric models of devices, boards, connectors and terminals respectively, and define Pins in the physical geometric model; S2. Establish a physical electrical signal model, and define a port (Port) for electrical signals in the physical electrical signal model; S3. The Pin, the Port, and the logic layer L are organized into a PLP, wherein the Pin is a terminal in the physical geometric sense, the Port is a port facing the electrical signal, and the Port corresponds one-to-one with the Pin. The logic layer L is used to carry the electrical signal semantics marked on the Port and establish the association between the PLP and the electrical logic circuit and the IEC61850 information model. S4. Receive a unified external electrical signal tag from an external data source, and mark the unified external electrical signal tag on the corresponding Port to form the electrical signal semantics of the Port; S5. Bind the electrical signal semantics marked on the Port to the corresponding PLP, combine multiple PLPs with common functional semantics, loop semantics or interface semantics to form a Function, and establish a matching relationship between the Function and the corresponding object in the IEC 61850 information model. S6. Based on the unified external electrical signal tag, compare and verify the association between Port, PLP, Function and their corresponding information model objects of secondary equipment from different manufacturers and / or different models; S7. Organize at least one PLP, at least one Function and their matching relationships according to the hierarchical relationship in the geometric model to form a device model, and export it as a structured file.

[0018] As a preferred option: In steps S3 to S6, a bidirectional association is established between the PLP and its corresponding graphic element, and an association is established between the Function corresponding to the PLP and the electrical graphic element in the electrical circuit. When a device, terminal, or related geometric object moves during the visualization modeling process, the position of the geometric primitive associated with the Pin is updated synchronously.

[0019] Thirdly, the present invention provides an electronic device, wherein the computer device includes a memory, a processor, and a computer program, and the computer program, when executed by the processor, implements the power secondary equipment visualization modeling and configuration method as described in the second aspect.

[0020] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the power secondary equipment visualization modeling and configuration method as described in the second aspect.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. By adopting the T / U grid system, which is highly compatible with the physical structure of power secondary equipment, a parameterized and standardized geometric modeling benchmark was established. This enables the geometric information of devices, boards, connectors and terminals to have a unified and computable structured expression, solving the problems of traditional geometric information relying on unstructured drawings, difficulty in accurate positioning and reuse, and significantly improving the accuracy of modeling and the convenience of software implementation.

[0022] 2. For the first time, the geometric and electrical attributes of physical terminals are integrated and encapsulated with the logical semantic attributes of external engineering signals into a unified PLP data object. This concept fundamentally solves the pain point of semantic separation between "physical terminals" and "logical ports" in traditional workflows, making each terminal an intelligent object that carries complete engineering semantics, providing a solid data foundation for subsequent automation applications.

[0023] 3. The system has a built-in template library for devices, panels, and connectors, supporting rapid instantiation and parametric adjustment based on templates. Users can avoid repetitive drawing work by calling and modifying standardized templates, which significantly improves modeling speed compared to traditional manual methods, while ensuring the consistency and standardization of model data across different projects.

[0024] 4. The structured device model generated by this invention, which contains complete PLP information, can be used as a standardized, machine-readable, and universal data format as input to multiple downstream automated engineering systems. This opens up the data flow from physical design to engineering configuration, reduces manual conversion steps, and improves overall engineering efficiency and data consistency.

[0025] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

[0038] To facilitate a better understanding of the embodiments of the present invention, its application scenarios will be explained before providing a detailed explanation of the specific implementation methods.

[0039] The power secondary equipment visualization modeling and configuration system described in this specification is applied to the engineering design, equipment development, and engineering configuration stages in fields such as power system relay protection and automated monitoring. In these scenarios, the application of this power secondary equipment visualization modeling and configuration system aims to achieve a unified digital expression of the equipment's physical structure and engineering logical semantics, providing a standardized and structured data foundation for the automated flow of design data, model-driven engineering configuration, and full lifecycle data management, thereby improving the design efficiency, data quality, and intelligence level of power secondary system engineering.

[0040] The following is a brief explanation of the secondary power equipment, physical logic ports, semantic bindings, parameterized grid cells, templates, structured files, Pins, Ports, logical layers (L), and Functions involved in the various embodiments of this specification: Secondary power equipment refers to intelligent electronic devices that monitor, control, protect, and regulate primary power equipment. These mainly include relay protection devices, measurement and control devices, remote terminal units (RTUs), and synchronous phasor measurement units (PMUs). These devices achieve their automation functions by receiving and transmitting electrical signals.

[0041] In this invention, a physical logic port refers to a unified data entity formed by fusing the physical terminals on a secondary power equipment with the logical semantics of the electrical signals they carry. This entity contains at least four types of information: geometric attributes, physical attributes, electrical attributes, and logical semantic attributes. It is the core data structure for realizing the association between the physical model and engineering semantics.

[0042] Semantic binding refers to the process of establishing a one-to-one correspondence between logical signals defined in external electrical signal annotations and their corresponding physical terminals in the geometric model. This process includes automatic matching based on identifiers and logical rule verification of attributes such as signal type and direction to ensure the correct and compliant association between electrical logic and physical structure.

[0043] The parametric grid unit, as defined in this invention, is a standardized geometric modeling benchmark system that includes a horizontal benchmark unit T (e.g., 5.08 mm) and a vertical benchmark unit U (e.g., 44.45 mm). The geometric dimensions and positions of all devices are parametrically defined as integer or fractional multiples of T and / or U, thereby achieving standardization and precision in model construction.

[0044] Templates refer to predefined, reusable, standardized model components, including device templates, plate templates, and connector templates. Templates contain typical geometries, connector layouts, and terminal configurations. Users can quickly instantiate new models by adjusting parameters, significantly improving modeling efficiency and consistency.

[0045] Structured files refer to file formats organized according to specific syntax and data structures, which can be automatically parsed and processed by computer programs. The device model files specifically described in this invention include formats such as XML, JSON, and SVG. These files explicitly express the hierarchical relationships, geometric information, and physical logic port data of the devices to achieve seamless data exchange with downstream systems.

[0046] In this invention, "pin" refers to a terminal in the physical geometric model of a secondary power equipment, representing a physical connection point on a device, plate, or connector, and has precise geometric position, size, and physical properties.

[0047] In this invention, "Port" refers to a port oriented towards electrical signals defined in the physical electrical signal model. It represents the logical access point of the electrical signal and corresponds one-to-one with the "Pin" in the physical geometric model, carrying electrical attributes such as the type, direction, and polarity of the electrical signal.

[0048] In this invention, the logic layer L refers to the semantic carrier layer in the PLP data entity, which is used to store the semantic information of electrical signals labeled on the Port and to establish the association between the PLP and the electrical logic circuit and the IEC 61850 information model.

[0049] In this invention, a Function refers to a functional organization object formed by combining multiple PLPs with common functional semantics, loop semantics, or interface semantics, corresponding to an electrical logic loop, used to realize the aggregation and organization of PLPs and matching with the IEC 61850 information model.

[0050] Example 1: like Figure 1 As shown, this embodiment provides a visualization modeling and configuration system for power secondary equipment based on external electrical signal annotation. The system includes a geometric modeling module, a physical electrical signal modeling module, a PLP construction module, an external electrical signal import module, a function organization module, an information model matching module, a consistency verification module, and a model export module. The modules work together to build a unified structured equipment model.

[0051] like Figure 2 As shown, the geometric modeling module establishes geometric models of the device, plate, connector, and terminal based on predefined parametric grid units, and records their coordinates and hierarchical relationships. In this embodiment, the parametric grid units adopt a standardized system with a horizontal reference T=5.08mm and a vertical reference U=44.45mm. The size and position of all geometric objects are based on this grid, and are accurately expressed and positioned as integer multiples or fractions of T and / or U. For example, the device width can be defined as 40T, the plate height as 2U, the connector size as 20mm×120mm, and the terminal spacing as 1T or 0.5T. The coordinate system takes the upper left corner of the device as the origin, and defines the precise position of each object through localX and localY coordinates. The system uses two-dimensional visualization rendering as the main interaction method, but also retains three-dimensional attribute information such as width, height, and depth to support possible subsequent three-dimensional visualization display or mechanical assembly verification and other extended needs. Figure 3 The geometric model of the terminal corresponds to the pin in the physical geometric model, that is, the terminal in the physical geometric sense.

[0052] The physical electrical signal modeling module is used to establish a physical electrical signal model and define ports (Ports) for electrical signals within that model. This module initially separates the logical attributes of electrical signals from their physical structure, laying the foundation for subsequent semantic fusion.

[0053] The PLP building module is used to organize the Pin, the Port, and the logic layer L into a unified physical logic port (PLP). For example... Figure 5 As shown, the Pin is a physical terminal in a geometric sense, and the Port is a port facing electrical signals. Each Port corresponds one-to-one with a Pin. The logic layer L is used to carry the electrical signal semantics labeled on the Port and establish the association between the PLP, the electrical logic circuit, and the IEC 61850 information model. Through this module, the system achieves the organic integration of physical geometry, electrical signal ports, and logical semantics.

[0054] like Figure 4 As shown, the external electrical signal import module receives electrical signal tags from external data sources and labels the unified external electrical signal tags onto the corresponding ports to form the electrical signal semantics of the ports. This module has good compatibility and scalability, supporting access to external signal data through various methods such as CSV, JSON, Excel files, database interfaces, or REST APIs. The input signal data contains structured fields, such as: signal name (signalName), type (e.g., DI / DO / AI), direction (IN / OUT), polarity (+ / -). The system includes / N, functional domains (such as Trip / Start / Measure / Block), external engineering database identifiers (externalID), and target terminal identifiers (targetTerminal, formatted as "J3-12"), providing a complete data foundation for subsequent automatic semantic binding.

[0055] The semantic binding module is used to semantically bind the electrical signals labeled on the Port to the corresponding PLP. During the binding process, this module automatically performs logical checks on key attributes such as signal type, direction, and polarity according to a preset engineering rule set. For example, it verifies the compatibility of the signal type with the physical type of the target terminal, whether the direction conforms to circuit logic, and whether the polarity setting matches engineering specifications, thereby ensuring the accuracy and engineering rationality of the binding relationship. The binding result serves as the basis for subsequent consistency verification module to compare and verify the association relationship.

[0056] The Function organization module is used to combine multiple PLPs with common functional semantics, loop semantics, or interface semantics to form a Function organization object, which corresponds to an electrical logic loop. In this embodiment, the module combines multiple PLPs according to the same hardware loop, the same functional unit, the same device interface boundary, and / or the same functional purpose. For example, all PLPs related to the same tripping loop are organized into a single Function, so that they logically correspond to a complete electrical functional unit.

[0057] The information model matching module is used to establish a matching relationship between the electrical logic circuit and the corresponding object in the IEC 61850 information model based on the Function. This module enables the system to seamlessly interface with the standardized communication information model, providing support for subsequent automatic configuration and communication binding.

[0058] The consistency verification module is used to compare and verify the association relationships between Ports, PLPs, Functions, and their corresponding information model objects between secondary devices from different manufacturers and / or different models, based on the unified external electrical signal label, providing a consistency verification means to establish a unified association between secondary devices from different manufacturers and / or different models. Specifically, this module performs consistency verification on at least one of the following: signal name, direction, functional domain, loop role, and interface semantics, ensuring data consistency across devices and systems. The model export module is responsible for exporting the constructed device model, i.e., a digital model containing at least one PLP, at least one Function, and their information model matching relationships, into a standardized structured file. Figure 6 As shown, the supported export formats include, but are not limited to, common, machine-readable formats such as XML, JSON, or SVG, so that the model can be directly recognized and used by downstream toolchains such as subsequent engineering design systems, schematic generation systems, or information model configuration systems.

[0059] In addition, the system in this embodiment also includes a physical electrical signal annotation module. This module serves as an auxiliary tool, allowing users to interact directly with terminal elements in the geometric model on a visual interface, manually adding or editing their electrical attribute annotations. This provides users with a flexible dual-operation approach: both automated processing via batch import of standard signal data through an external interface and fine-grained manual adjustments and annotations locally, enhancing the system's adaptability and ease of use in practical engineering applications.

[0060] Through the organic combination and streamlined operation of the above modules, this embodiment system realizes the entire process from parametric geometric modeling, automatic access and binding of external signals, to the generation of multi-attribute PLP entities and the final output of a structured model, effectively solving the problems of unstructured geometric information, manual signal binding, and fragmented data models in traditional methods.

[0061] Example 2: This embodiment provides a method for visual modeling and configuration of secondary power equipment, characterized by applying the system described in Embodiment 1, including the following steps: S1. Geometric modeling steps: Based on predefined parametric grid cells, establish geometric models of devices, plates, connectors and terminals, and record their coordinates and hierarchical relationships.

[0062] S2. Physical Electrical Signal Modeling Steps: Establish a physical electrical signal model and define ports (Ports) for electrical signals within the model. This step initially separates the logical attributes of electrical signals from their physical structure, laying the foundation for subsequent semantic fusion.

[0063] S3. PLP Construction Steps: The Pin, Port, and Logic Layer L are organized into a Physical Logic Port (PLP). Here, the Pin is a physical geometric terminal, the Port is a port facing electrical signals, and there is a one-to-one correspondence between the Port and the Pin. The Logic Layer L is used to carry the electrical signal semantics labeled on the Port and to establish the association between the PLP and the electrical logic circuit and the IEC 61850 information model.

[0064] S4. Signal Import and Labeling Step: Receive unified external electrical signal tags from an external data source and label the unified external electrical signal tags to the corresponding ports to form the electrical signal semantics of the ports. This step supports accessing external signal data through various methods such as CSV, JSON, Excel files, database interfaces, or REST APIs. When an external signal does not match a corresponding port, the system provides automatic prompts and supports interactive labeling.

[0065] S5. Semantic Binding and Function Organization Steps: The electrical signal semantics labeled on the Port are semantically bound to the corresponding PLP. Simultaneously, rule checks are performed on at least one of the following: signal type, direction, polarity, terminal type, and functional domain, according to preset rules. Then, multiple PLPs with common functional semantics, loop semantics, or interface semantics are combined to form a Function organization object, where each Function corresponds to an electrical logic loop. In this step, multiple PLPs can be combined according to the same hardware loop, the same functional unit, the same device interface boundary, and / or the same functional purpose. For example, all PLPs related to the same tripping loop can be organized into one Function.

[0066] S6. Information Model Matching Step: Based on the Function, establish a matching relationship between the electrical logic circuit and the corresponding object in the IEC 61850 information model.

[0067] S7. Consistency Verification Step: Based on the unified external electrical signal label, compare and verify the association relationships between Ports, PLPs, Functions, and their corresponding information model objects between secondary equipment from different manufacturers and / or different models. Specifically, verify at least one of the following: signal name, direction, functional domain, loop role, and interface semantics, to provide a consistency verification method for establishing a unified association between secondary equipment from different manufacturers and / or different models.

[0068] S8. Model Construction and Export Steps: Organize at least one PLP, at least one Function, and their information model matching relationships according to the hierarchical relationship in the geometric model to form a device model, and export it as a structured file. Supported export formats include common, machine-readable formats such as XML, JSON, or SVG. This file contains structured PLP information and Function information that can be directly recognized by downstream engineering design systems, schematic generation systems, or communication model configuration systems.

[0069] In steps S3 to S6 above, a bidirectional association is established between the PLP and its corresponding geometric elements, and an association is established between the Function corresponding to the PLP and the electrical elements within the electrical circuit. When a device, terminal, or related geometric object moves during the visualization modeling process, the position of the geometric element associated with the Pin is updated synchronously; when the PLP attribute is modified, the visualization annotation of the associated geometric element is updated in real time; when the Function organization relationship is adjusted, its associated electrical circuit elements and information model matching relationship are updated synchronously accordingly.

[0070] Through the orderly execution of the above steps, this method realizes a complete process from parametric geometric modeling, physical electrical signal modeling, PLP construction, external signal import and binding, function organization, information model matching to consistency verification and structured model export. It effectively solves the problems of unstructured geometric information, manual signal binding, fragmented model data, and difficulty in ensuring cross-device consistency in traditional workflows, and significantly improves modeling efficiency and data quality.

It is understood that the modem may also be implemented as a separate chip without being integrated into the processor.
