Description

Technical Field

[0001] This invention relates to the field of prefabricated component reuse management technology, and in particular to a cross-project reuse matching method, system, medium and processor for prefabricated components for temporary substation construction. Background Technology

[0002] With the rapid development of power infrastructure construction, the number of substation projects is increasing year by year. During project construction, a large number of temporary buildings and facilities are typically required, such as construction office areas, equipment storage areas, and safety fencing. To improve construction efficiency and standardization, prefabricated components are increasingly being used for the rapid assembly of temporary substation facilities. These components are modular, detachable, and easily reusable, and theoretically can be reused across different projects, thereby reducing material procurement costs, minimizing resource waste, and meeting the requirements of green construction and sustainable development.

[0003] However, in actual engineering management, the reuse of prefabricated components for temporary substation construction across projects still faces many difficulties, mainly in the following aspects: Component information management is fragmented and lacks a unified digital archive. Currently, component information relies heavily on paper records or scattered spreadsheets, resulting in incomplete and untimely updates. This makes it difficult to systematically trace and share key data such as component specifications, performance status, usage history, and damage conditions, thus failing to provide reliable data support for cross-project reuse.

[0004] Requirements analysis and component matching rely on manual experience, which is inefficient. New projects often rely on manual estimation and experience-based judgment for component requirements, lacking systematic methods for requirement extraction and parameterized description. This makes it difficult to quickly and accurately match with existing component libraries, easily leading to matching errors, specification mismatches, or substandard performance.

[0005] The component selection process lacks a scientific evaluation system. Existing reuse decisions are mostly based on a single factor (such as size or condition), without comprehensively considering multi-dimensional factors such as the component's geometric adaptability, structural performance, damage status, remaining life, economic efficiency, and historical usage performance. This makes it impossible to achieve a systematic and intelligent ranking and recommendation of components based on their merits.

[0006] Therefore, the existing technology lacks a cross-project reuse management method that can systematically integrate the entire life cycle information of components, realize intelligent matching and scientific recommendation, and support standardized repair and allocation. This results in low reuse rate of prefabricated components for temporary substation construction, serious waste of resources, increased project costs, and is not conducive to the green and digital transformation and upgrading of the industry.

[0007] Therefore, there is a need for a cross-project reuse matching method, system, medium, and processor for prefabricated components for temporary substation construction. Summary of the Invention

[0034] Example 1 like Figure 1 As shown, a method for cross-project reuse and matching of prefabricated components for temporary substation construction includes the following steps: S1: Digitally archive information on the entire life cycle of prefabricated components to form a component database.

[0035] For all types of prefabricated components (such as wall panels, floor slabs, beams, columns, and connectors) used in temporary substation facilities, establish digital archives covering their entire lifecycle, specifically including the following sub-steps: S11: Generate a unique code for each prefabricated component and enter its basic information. The basic information includes: component code (following a unified coding rule, such as "component type-production batch-serial number"), component type, name and functional classification, geometric dimensions, design specifications and tolerance range, material composition, strength grade and durability index, manufacturer, production date, quality inspection report number, and factory qualified status.

[0092] All test results must be recorded and a repair quality report must be generated. Only after the test results are qualified can the next stage be carried out.

[0093] S44: After the quality acceptance is passed, the component's file information must be updated in the full life cycle management platform in a timely manner, including: Supplement the repair record (repair time, repair content, implementing unit, quality report number); update the component status rating (e.g., change from "requires repair" to "intact" or "repaired and usable"); rebind or update the latest status information in physical identifiers (e.g., QR codes / RFID); if the repair involves performance improvements or changes, the component technical parameters must be updated simultaneously.

[0094] The updated information will serve as the basis for subsequent matching and use of this component, forming a traceable data loop.

[0095] S5: Provide guidance on component allocation, transportation, and on-site assembly based on the recommended list of compatible components. Specific procedures are as follows: After completing component screening, repair, and quality re-inspection, the allocation, transportation, and on-site assembly of components must be organized and implemented according to the final confirmed list of compatible components. This step aims to ensure the safe and efficient transfer of components from storage locations to the new substation project site and to guide on-site personnel in standardized and precise assembly. Specifically, it includes the following sub-steps: S51: Develop detailed component allocation plans and transportation schemes.

[0096] Allocation Plan Development: Based on the "reuse priority," storage location, repair status, and new project construction progress of the components in the recommended list of compatible components, a detailed allocation sequence plan should be developed. The plan should clearly specify the allocation time, responsible unit, and handover personnel for each batch of components, and consider resource coordination between multiple projects to avoid conflicts.

[0097] Transportation plan design: Based on the characteristics of the substation project site (such as mountainous areas, urban areas, or transportation limitations), design reasonable transportation routes and methods. For oversized, overweight, or specially shaped components, a specific transportation plan must be developed, including the selection of suitable transport vehicles, hoisting equipment, and necessary traffic coordination measures.

[0098] Standardized Packaging and Protection: All transferred components will be packaged and protected using standardized methods to prevent damage, contamination, or loss of labeling during transportation. Specifically, this includes: Use specialized corner protectors and shock-absorbing materials to protect the edges and corners of components and connection points; Apply a transparent film or protective cover to areas with QR code / RFID tags to ensure the tags are readable; The package includes a list of components, an assembly diagram, and instructions.

[0099] S52: Provide assembly drawings and process instructions, and implement "dry operation".

[0100] Assembly document preparation: Provide detailed assembly drawings, 3D models (such as BIM models), and process guidance manuals for each type of component. The drawings must clearly indicate key parameters such as component number, installation location, connection method, and tightening torque, and be associated with the component's physical identification (QR code / RFID) to support on-site scanning for viewing.

[0101] "Dry Operation" Implementation: The assembly process fully adopts "dry operation" (i.e., a prefabricated construction method with no wet work and minimal welding), emphasizing rapid assembly processes such as bolt connections and snap-fit ​​connections. On-site, components are positioned, aligned, and fixed according to the drawings to ensure that the installation accuracy meets the design tolerances.

[0102] Training and technical briefing: Organize special training and technical briefing for on-site construction personnel before assembly to ensure that they understand the assembly process, master the use of tools, and are familiar with safety and quality requirements.

[0103] S53: On-site technical support and process recording.

[0105] Assembly process record: Real-time recording of key data during the assembly process, such as installation time, self-inspection results of installation quality, technical problems encountered and solutions.

[0106] Problem feedback and optimization suggestion collection: Record issues such as component mismatch and connection difficulties encountered during assembly and simultaneously report them to the full lifecycle management platform. Collect optimization suggestions from on-site personnel regarding component design, connection methods, and label placement, serving as input for subsequent component optimization and matching algorithm improvements.

[0107] S6: After the project is completed, collect information on component usage and update the archives to form a data loop. The specific steps are as follows: S61: Systematically collect and record the actual performance data of components during this usage cycle. After the completion of the temporary construction project of the substation, the on-site technical personnel shall cooperate with the full life cycle management platform to complete the collection and entry of the following data: 1. Performance Record: Record the actual usage time of each component in this project, the environmental conditions it is subjected to (such as temperature and humidity changes, corrosion factors, frequency of mechanical loads, etc.), and whether temporary reinforcement or adjustment is required.

[0108] 2. New damage detection and assessment: Before disassembly, conduct a comprehensive inspection of the components, identify and record any new damage that occurs during this use, including: damage type (such as deformation, cracks, surface wear, coating peeling, loosening of connectors, etc.); damage location and extent; and a preliminary assessment of whether it will affect subsequent reuse.

[0109] 3. Disassembly process record: Record the disassembly method, disassembly time, whether secondary damage was caused during the disassembly process, and the initial storage status after disassembly.

[0110] S62: Feed the collected data back to the lifecycle management platform in real time to update the component archives. Based on the data collected in S61, complete the following archive update operations in the lifecycle management platform: Supplement the usage record for this instance: Add the project name, start and end dates of usage, usage scenario, environment summary, and cumulative usage duration to the "Usage History" section of the component archive.

[0111] Update damage and repair records: Link the newly added damage records with historical damage records to form a complete damage timeline view; if simple on-site repairs were performed after disassembly, the repair content, time and results are recorded simultaneously.

[0112] Reassess the component status: Based on the latest damage information and the platform's preset status rating rules, re-determine the component status level (such as "intact", "minor damage", "requires repair", "recommends retirement" etc.).

[0113] Update physical identification information: If the status, rating or key parameters of a component change, update the information in its QR code / RFID tag to ensure that the identification is consistent with the file.

[0114] S63: Generate a project component reuse benefit report to form a closed-loop management system. Based on the actual reused component data in this project, the platform automatically compiles and generates a reuse benefit analysis report, which includes: Reuse rate statistics: Statistics on the proportion of reused components in the intermediate components of this project and the distribution of the projects from which the reused components originate.

[0115] Economic analysis: Estimate the savings in procurement costs, transportation and repair costs due to component reuse, and compare them with a completely new procurement plan.

[0116] Environmental benefit assessment: Calculate green construction indicators such as carbon emission savings and raw material savings resulting from reducing the production of new components.

[0118] S64: Archive the report and initiate preparations for the next round of reuse. Archive the project reuse report to the platform database as a reference for subsequent project matching. At the same time, use the updated component database as the basis for the new round of matching, realizing the continuous accumulation and closed-loop management of component lifecycle data.
