Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and more specifically, to a method, apparatus, device, and storage medium for modifying equipment. Background Technology

[0002] Equipment retrofitting is a common technological upgrading method in the industrial sector, especially in critical infrastructure fields such as power, manufacturing, and transportation. As equipment ages or technical standards improve, it is necessary to replace or upgrade in-service equipment. Taking the retrofitting of generator set protection cabinets as an example, after the protection devices of generator sets exceed their service life, they must be updated in accordance with the requirements of major power grid anti-accident measures to ensure the safe and stable operation of the power system.

[0003] Currently, there are two common technical models for upgrading such equipment: one is to completely dismantle the old equipment, install brand new equipment with pre-wired internal wiring at the factory, and reconnect all external cables to the terminal blocks of the new equipment. This approach offers controllable quality but is costly, time-consuming, and results in the forced scrapping of still usable old cabinets and cables, leading to significant resource waste. The other approach retains some of the original equipment structure, replacing only certain components, with construction workers manually wiring the new functional units on-site according to the old drawings to adapt to the existing external wiring. This approach is economical and maximizes the use of existing assets, but its quality relies entirely on the personal experience of the construction workers, lacking standardized processes and quality control methods, resulting in a high wiring error rate and poor workmanship consistency. Summary of the Invention

[0004] To address the aforementioned technical problems, this disclosure provides a method, apparatus, device, storage medium, and program product for equipment modification, which can improve the accuracy of the obtained fault maintenance strategy.

[0005] To achieve the above objectives, in a first aspect, this disclosure provides a method for modifying equipment, the method comprising: Acquire point cloud data of the equipment to be modified; A digital twin model of the equipment to be modified is generated based on the equipment drawings and the point cloud data. Based on the size and interface definition of the target functional unit, the relative installation posture of the target functional unit and the device to be modified is planned in the digital twin model, and the correspondence between the inherent cable core wires of the device to be modified and the interface of the target functional unit is established according to the interface definition; wherein, the target functional unit is used to replace the functional unit to be modified in the device to be modified, the relative installation posture includes the installation position and / or installation orientation, and the target functional unit can be installed in a way that embeds, attaches, or surrounds the device to be modified; Based on the relative installation pose and the corresponding relationship, a modification operation guidance document is generated to guide the modification of the equipment to be modified.

[0006] Secondly, this disclosure provides an equipment modification apparatus, the apparatus comprising: The point cloud data acquisition module is used to acquire point cloud data of the equipment to be modified. The model generation module is used to generate a digital twin model of the equipment to be modified based on the equipment drawings and the point cloud data. The planning module is used to plan the relative installation position of the target functional unit and the equipment to be modified in the digital twin model according to the size and interface definition of the target functional unit, and to establish the correspondence between the inherent cable core wires of the equipment to be modified and the interface of the target functional unit according to the interface definition. The document generation module is used to generate a modification operation guidance document based on the relative installation pose and the correspondence, which guides the modification of the equipment to be modified.

[0007] Thirdly, this disclosure provides an electronic device, including: A memory on which computer programs are stored; A processor is used to execute the computer program in the memory to implement the above-described device modification method.

[0008] Fourthly, this disclosure provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-described device modification method.

[0009] Fifthly, this disclosure provides a computer program product, including a computer program, characterized in that the computer program, when executed by a processor, implements the above-described device modification method.

[0010] The above technical solution first utilizes point cloud data and equipment drawings to construct a digital twin model of the equipment to be modified, achieving a precise mapping of physical equipment to digital space. Then, based on the size and interface definition of the target functional unit, the digital twin model generates a correspondence between the relative installation pose and the inherent cable core wires of the equipment to be modified and the interface of the target functional unit, and eliminates interface conflicts in advance through virtual assembly. Finally, a work instruction document containing prefabricated drawings and assembly positioning diagrams is generated, transforming on-site operations from manual wiring relying on personal experience to standardized and modular rapid assembly, thereby significantly shortening the construction period and reducing labor costs while ensuring quality.

[0011] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0018] Figure 7 This is a schematic diagram of the structure of an electronic device for performing a device modification method, according to an exemplary embodiment of the present disclosure. Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] Figure 1 This is a flowchart illustrating a device modification method according to an exemplary embodiment of this disclosure. The method can be executed by an electronic device, which can be a terminal device or a server; that is, the method can be executed by the terminal device or the server alone, or by the terminal device and the server working together.

[0021] Taking the server as the execution entity as an example, the specific implementation process of this method is as follows: Step S110: Obtain point cloud data of the equipment to be modified.

[0022] The equipment to be upgraded can be in-service industrial equipment, such as generator set protection cabinets, power distribution cabinets, and control cabinets. Point cloud data is used to characterize the three-dimensional spatial structure of the equipment to be upgraded.

[0023] Step S110 above may be: acquiring point cloud data containing the structural dimensions, internal spatial layout and cable interfaces of the device to be modified by scanning the device to be modified by a 3D laser scanner.

[0024] Step S110 above can also involve taking high-resolution images of the equipment to be modified from multiple angles, performing three-dimensional reconstruction using computer vision algorithms (such as Structure from Motion, SfM), and generating point cloud data of the equipment to be modified.

[0025] The above-described method for obtaining point cloud data of the equipment to be modified is only illustrative; there are many other ways to obtain it, which are not specifically limited here.

[0026] Step S120: Generate a digital twin model of the equipment to be modified based on the equipment drawings and the point cloud data.

[0027] The equipment drawings include the original electrical schematics, terminal layout diagrams, panel layout diagrams, wiring diagrams, etc., of the equipment to be modified. The digital twin model is a three-dimensional digital model containing geometric and electrical connection information.

[0028] Step S120 above can be to register and fuse point cloud data with equipment drawings. Specifically, the point cloud coordinate system can be aligned with the drawing coordinate system, and then a solid model can be generated in 3D modeling software based on the aligned point cloud outline. According to the drawing information, the position of each terminal block, cable number, core wire color and destination and other electrical attributes are marked in the model to obtain a digital twin model of the equipment to be modified.

[0029] Step S120 above can also be to directly export the existing three-dimensional design model (such as BIM model) of the equipment to be modified from the equipment management system, and then use point cloud data and equipment drawings to correct the deviation of the model to obtain a digital twin model of the equipment to be modified.

[0030] Step S130: Based on the size and interface definition of the target functional unit, plan the relative installation pose of the target functional unit and the device to be modified in the digital twin model, and establish the correspondence between the inherent cable core wires of the device to be modified and the interface of the target functional unit based on the interface definition.

[0031] The target functional unit is used to replace the functional unit to be modified in the device to be modified. The relative installation posture includes the installation position and / or installation orientation, and the target functional unit can be installed in a manner that embeds, attaches, or surrounds the device to be modified.

[0032] For example, in the renovation of generator set protection cabinets, the functional unit to be renovated is the original protection device, and the target functional unit is the new protection device. In the renovation of server racks in data centers, the equipment to be renovated is the server rack, the functional unit to be renovated is the original server node (or the original compute / storage node), and the target functional unit is the new server node (new compute / storage node). It should be understood that the above-mentioned equipment to be renovated is only illustrative, and the specific functional units to be renovated are also illustrative and are not specifically limited here.

[0033] In one possible implementation, please refer to Figure 2 The above step S130 may specifically include steps S132-S134.

[0034] Step S132: Based on the interface definition of the target functional unit and the spatial layout of the equipment to be modified in the digital twin model, the target functional unit is decomposed into multiple independent functional sub-modules, and the relative arrangement relationship between each functional sub-module and the size and interface definition of each functional sub-module are determined.

[0035] For example, in the renovation of generator set protection cabinets, if the unit to be renovated is the original protection device, the new protection device can be decomposed according to functional logic into multiple functional sub-modules, including at least one of the following: main protection device module, operating box module, power supply and input module, and output trip module. Based on the internal space dimensions of the cabinet (such as height partitioning and depth restrictions), module boundaries are defined in a digital twin model, and the width, height, depth, and interface terminal block arrangement of each sub-module are determined using the software's measurement and annotation functions.

[0036] Step S134: Based on the size and interface definition of each functional sub-module, plan the relative installation position of each functional sub-module and the equipment to be modified in the digital twin model, and establish the correspondence between the inherent cable core wires of the equipment to be modified and the interfaces of each functional sub-module.

[0037] Specifically, based on the digital twin model of the equipment to be modified, the 3D models of each functional sub-module, and the interface definitions, the system can automatically check for interference between sub-modules and between sub-modules and cabinet doors / frames / existing cable trays, and adjust the positions of the functional sub-modules until there is no interference between them. Simultaneously, using the software's "wiring table editor," the original terminal numbers of each core wire in the original cable wiring table are mapped, line by line or in batches, to the corresponding functional terminals of the new sub-module, generating a new and old terminal comparison table.

[0038] For example, based on the digital twin model of the equipment to be modified, the three-dimensional model of each functional sub-module, and the interface definition, a multi-objective optimization algorithm (such as a genetic algorithm or particle swarm optimization algorithm) can be used to automatically search for the optimal installation position of each sub-module with the objectives of minimizing interference, minimizing the total wiring length, and / or maximizing maintainability.

[0039] By employing steps S132-S134, firstly, modular decomposition is performed based on the interface definition of the target functional unit and the spatial layout of the equipment to be modified. This breaks down the complex overall modification task into multiple independent, parallel-processable functional sub-modules, reducing the design and assembly complexity of the target functional unit. Secondly, interference checks and pose optimization are performed using a digital twin model, enabling the early detection and elimination of mechanical structural conflicts in a virtual environment. This avoids rework and delays caused by size discrepancies and insufficient space in traditional on-site construction. Furthermore, by establishing the correspondence between the inherent cable cores of the equipment to be modified and the interfaces of each functional sub-module, the accuracy and traceability of wiring mapping are ensured, eliminating the risk of errors that are prone to occur with manual wiring.

[0040] Step S140: Based on the relative installation pose and the correspondence, generate a modification operation guidance document to guide the modification of the equipment to be modified.

[0041] The modification operation guidance document refers to a set of digital technical documents used to guide workshop prefabrication and on-site construction. It may include prefabricated drawings of each functional sub-module (such as module assembly drawings, internal wiring diagrams, terminal block diagrams, and component lists) and on-site assembly and positioning diagrams of each functional sub-module (such as installation baseline diagrams, positioning tooling layout diagrams, cable wiring comparison tables, and verification process cards). This is to accurately transmit the virtual design results to the physical modification stage, transforming on-site operations from manual operations that rely on personal experience to standardized and modular rapid assembly. This significantly improves the consistency of modification quality, reduces reliance on highly skilled workers, and forms traceable construction records.

[0042] In one possible implementation, step S140 may be: determining the overall installation position and orientation of the target functional unit in the equipment to be modified based on the relative installation posture, generating a wiring comparison table of all inherent cable cores and the overall interface of the target functional unit based on the correspondence, and then generating a modification operation guidance document containing the overall assembly drawing, overall wiring diagram and on-site installation positioning diagram of the target functional unit.

[0043] In another possible implementation, please refer to Figure 3 Step S140 may specifically include: Step S142: Based on the relative arrangement relationship between each functional sub-module and the size and interface definition of each functional sub-module, generate the structural design of each functional sub-module.

[0044] The structural design of the functional submodules may include one or more of the following: backplane layout, guide rail position, component arrangement, and internal wiring path.

[0045] Step S144: In the digital twin model, according to the installation position and structural design of each functional sub-module, the functional sub-module is assembled to the corresponding position of the device to be modified, and the inherent cable core wire is connected to the interface of the functional sub-module according to the correspondence, so as to obtain the assembled digital twin model.

[0046] Specifically, the assembly simulation function of a digital twin platform can be used to place the 3D model of each functional sub-module into the model of the equipment to be modified according to its corresponding installation pose (coordinates and orientation). Simultaneously, components (such as terminal blocks) and wiring in the internal structural design of the functional sub-modules are mapped. Then, based on the wiring correspondence, the 3D curves representing each inherent cable core are connected to the corresponding positions of the terminals of the corresponding functional sub-module in the virtual environment. Collision detection (including interference between sub-modules and cabinet doors, frames, existing cable trays, and adjacent sub-modules) and electrical connection integrity checks (such as whether there are unconnected cores or duplicate wiring) can be automatically performed during assembly. If interference or errors are found, the poses of each functional sub-module are adjusted until all checks pass, ultimately generating the assembled digital twin model.

[0047] Step S146: Based on the assembled digital twin model, generate a modification operation guidance document including prefabricated drawings of each functional sub-module and on-site assembly and positioning diagrams of each functional sub-module.

[0048] Among them, the prefabricated drawings are used for offline manufacturing of the module entities in the workshop, and the on-site assembly and positioning drawings are used to guide the installation of each functional sub-module.

[0049] By employing steps S142-S146 above, after generating the detailed structural design of each functional sub-module, complex tasks such as internal wiring and component arrangement can be completed offline in the workshop environment. This transforms manual wiring on-site into standardized module prefabrication, significantly improving wiring quality and consistency. Furthermore, by performing virtual assembly in the digital twin model, the installation posture and wiring mapping relationship of each sub-module can be verified in advance to eliminate mechanical interference and electrical errors, avoiding rework and delays caused by dimensional discrepancies or wiring mistakes in traditional on-site construction. Finally, based on the assembled digital twin model, prefabricated drawings and on-site assembly positioning diagrams are automatically output, forming a work instruction document from virtual design to physical implementation, improving the efficiency of subsequent on-site assembly.

[0050] By adopting the equipment modification method of this application, a digital twin model of the equipment to be modified is first accurately constructed using point cloud data and equipment drawings, realizing the accurate mapping of physical entities to digital space. Then, based on the size and interface definition of the target functional unit, the relative installation posture of the target functional unit and the equipment to be modified is planned in the digital twin model, and the correspondence between the inherent cable core wires and the interface of the target functional unit is established. Through virtual assembly, mechanical interference and electrical mapping errors are eliminated in advance, transforming the manual wiring that relies on personal experience and is prone to errors in traditional on-site construction into a standardized and verifiable modification operation guidance document. This allows for subsequent equipment modification based on the modification operation guidance document, making on-site operations more standardized, efficient, and reliable.

[0051] Furthermore, by modularly decomposing the target functional units, the complex renovation task is broken down into multiple independent functional sub-modules, enabling parallel prefabrication and offline assembly. This further shortens the critical path duration, reduces on-site reliance on highly skilled workers, and establishes a complete end-to-end quality traceability chain. Therefore, this method significantly reduces the cost and duration of the renovation project.

[0052] Please see Figure 4 After generating the work instruction document, the method disclosed herein may further include the following steps: Step S150: Based on the prefabricated drawings of each functional submodule, assemble and generate the module entity of each functional submodule.

[0053] It is worth mentioning that this step is carried out in a non-site workshop environment. On a prefabrication platform, the internal devices of the module are installed, terminal blocks are fixed, and internal wiring and cable trays are arranged according to the prefabrication drawings. After completion, equipment such as a relay protection tester is used to pre-test the module to ensure that the internal functions of the module are correct.

[0054] Step S160: Control the modification tooling to remove the functional unit to be modified from the equipment to be modified, install the module entity of each functional sub-module to the corresponding position of the equipment to be modified, and connect the inherent cable core wire to the interface of each module entity according to the correspondence.

[0055] Specifically, positioning fixtures (such as positioning clamps and assembly guides) can be set on the equipment to be modified to provide an installation reference for the module entities of the functional sub-modules; thereafter, the modification fixtures can be controlled to set the module entities of the functional sub-modules on the positioning fixtures and connect the inherent cable cores to the interfaces of each module entity according to the correspondence.

[0056] Optionally, the module entity can be verified before installation, and installation can proceed only if the verification passes; a re-verification can also be performed after installation.

[0057] The verification of the module entity can be performed by performing circuit continuity verification, integrity verification, insulation verification, etc. The specific verification method can be determined according to the type and security level of the module entity, and is not specifically limited here.

[0058] Optional, please refer to Figure 5 The methods also include: Step S170: Assign a module identifier to each functional submodule.

[0059] Step S180: In the module entity modification implementation stage, the modification operation data of the modification implementation stage is associated with the module identifier and stored in the target database.

[0060] The modification implementation process includes at least one of the following: assembly, installation, wiring, and verification of the module entity.

[0061] By scanning QR codes or RFID tags, the entire lifecycle data of each module (pre-built test reports, installation personnel, verification results, etc.) is automatically recorded, forming a complete quality traceability chain.

[0062] The following explanation will be based on the example of the modification of the generator set protection cabinet.

[0063] Specifically, taking the generator set protection cabinet as the equipment to be modified, the original protection device of the generator set protection cabinet as the functional unit to be modified, and the new protection device as the target functional unit, the following is an example: The original protection device includes five cabinets: A, B, C, D, and E. The method disclosed in this paper is used for modification, and the specific process is as follows: I. Digital Surveying and Precision Design Point cloud data acquisition: A 3D laser scanner is used to scan the five old protective cabinets (A, B, C, D, and E) in operation to obtain high-precision point cloud data including cabinet structural dimensions, internal spatial layout, terminal block positions, and cable entry positions.

[0064] Generate a digital twin model: Register and integrate point cloud data with the original equipment drawings (electrical schematic diagram, terminal block diagram, and panel layout diagram) to create a complete digital twin model of the equipment to be modified (old cabinet) in 3D modeling software, and accurately label the original terminal number, core color, and destination of each inherent cable core.

[0065] Planning the relative installation positions and wiring correspondences: The target functional unit for the first set of protection (panels A, C, and E) is determined to be the NARI PCS-985 series new protection device, and the target functional unit for the second set of protection (panels B and D) is the Beijing Sifang CSC-326 series new protection device. Based on the dimensions and interface definitions of the new protection devices, the relative installation positions (installation locations and orientations) of each new protection device and the equipment to be modified are planned in the digital twin model. Simultaneously, the correspondence between the existing cable cores and the interfaces of the new protection devices is established, generating a comparison table of old and new terminals.

[0066] Modular Decomposition: If functional modular prefabrication is adopted, the new protection device is decomposed into multiple independent functional sub-modules, such as one or more of the following: main protection device module, operating box module, power supply and switch module, tripping module, etc., and the relative arrangement, size, and interface definition of each sub-module are determined. If the overall cabinet modular prefabrication variant is adopted, the entire new protection system is regarded as a whole functional sub-module, and no internal disassembly is performed.

[0067] Generate structural design and virtual assembly: Based on the dimensions and interface definitions (or overall structure) of each functional submodule, generate the structural design (backplane layout, component arrangement, internal wiring paths). In the digital twin model, according to the installation posture and structural design of each functional submodule, assemble it to the corresponding position of the equipment to be modified, and connect the inherent cable cores to the interfaces of each submodule according to the wiring correspondence, obtaining the assembled digital twin model. Collision detection is used to automatically check for interference and make adjustments to ensure no mechanical conflicts and no wiring errors.

[0068] Generate modification operation guidance documents: Based on the assembled digital twin model, output modification operation guidance documents, including prefabricated drawings of each functional sub-module (module assembly drawing, internal wiring diagram, terminal block diagram, component list) and on-site assembly positioning diagrams (installation baseline diagram, positioning tooling layout diagram, cable wiring reference table, verification process card). If an overall modular solution is adopted, generate overall prefabricated drawings and overall installation positioning diagrams.

[0069] Phase Two: Modular Prefabrication and Factory Testing In a non-site workshop environment, offline prefabrication is carried out according to prefabricated drawings: new protection devices, circuit breakers, relays, terminal blocks, etc., are installed on prefabricated back panels or rails, and all wiring inside the module is strictly completed; a relay protection tester is used to pre-test the module to ensure correct internal functions; each module is assigned a unique identifier (QR code or RFID) and information such as model number and test data is recorded. If an integrated modular solution is adopted, the entire cabinet is prefabricated as a large module, which is larger in size but has the least amount of on-site wiring.

[0070] Phase 3: Rapid on-site assembly with tooling Dismantle the functional units to be upgraded: After a safe power outage, remove the original protection devices, old terminal blocks and other internal components in the old cabinet, while retaining the cabinet body and all external cables.

[0071] Installation positioning fixtures: Dedicated positioning fixtures (such as positioning clamps or assembly rails) are fixed onto the equipment to be modified, providing an installation reference for the module. Alternatively, augmented reality (AR) technology can be used, where virtual positioning lines are overlaid onto the real cabinet using AR glasses to guide installation.

[0072] Install the module entity: Transport the prefabricated module entity (sub-functional module or overall module) to the corresponding screen position, push it in via guide rail or clamp it into the predetermined position, and tighten it with bolts.

[0073] Wiring and Verification: Connect the inherent cable cores to the corresponding terminals on the module according to the wiring reference table. Before installation, use a portable verification bench to perform a loop verification on the module. Installation can proceed only after the verification is passed; a re-verification should be performed after installation. If an integrated modular solution is used, the wiring is minimal, requiring only the connection of external cables.

[0074] Phase 4: Closed-Loop Data Management and Digital Delivery During the assembly, pre-debugging, installation, wiring, and verification of each module entity, the modification operation data (test report, operator, time, and verification result) of each stage are associated and stored in the target database by scanning the module identifier.

[0075] After debugging, digital as-built data that is completely consistent with the physical system is generated based on the database. This includes an interactive 3D digital twin model of the equipment to be modified after the modification is completed. By clicking on any terminal, its specifications, wiring information and test records can be viewed, forming a complete quality traceability chain.

[0076] By adopting the equipment modification method of this solution, compared with the traditional screen replacement and rewiring solution, it can save about 40% of the modification cost and shorten the critical path construction period by 50%. In addition, the functional sub-module solution is flexible and easy to transport, and the overall modular solution has the fastest on-site wiring, which can be selected according to the actual situation.

[0081] Optionally, the modified control module is also used to verify the module entity; if the verification passes, the module entity of each functional sub-module is installed at the corresponding position of the device to be modified.
