Description

Technical Field

[0001] This invention relates to the field of digital building design technology, and in particular to a web-based method, device, and storage medium for collaborative delivery of attribute data of BIM operation and maintenance models. Background Technology

[0002] With the widespread application of BIM in the design and construction phases, owners are placing higher demands on the integrity and availability of data during the "completion to operation and maintenance" phase. The information required in the operation and maintenance phase includes not only geometric elements but also structured attribute data (equipment parameters, operation / maintenance manual indexes, maintenance cycles, parts lists, and supply chain information, etc.). This data is the foundation for achieving digital operation and maintenance and reducing operating costs.

[0003] In recent years, cloud-based / web-based BIM collaboration platforms have developed rapidly. Mainstream platforms offer real-time viewing, annotation, issue management, and basic attribute editing functions. However, most tools still lack sufficient support for specialized "Operation and Maintenance Delivery" processes (such as pre-setting attribute templates by equipment type, distributing attribute sub-tasks by role, real-time collaborative delivery by multiple parties, and automatically generating standardized deliverables). Currently, several issues remain to be addressed in the handover process from the completed BIM model to the operation and maintenance phase.

[0004] (1) As-built models are usually derived from construction phase models and often lack key attribute data required for operation and maintenance (such as maintenance cycle, equipment maintenance records, spare parts information, supplier contact information, etc.). This leads to a large amount of secondary data entry and organization required by the owner when receiving the model, thereby increasing delivery costs and time. Academic and industry research generally points out that information loss and incomplete attributes are the core problems in the migration from BIM to FM system.

[0005] (2) The data delivery format is inconsistent with the standard implementation. Although delivery specifications such as COBie have proposed the transmission of structured operation and maintenance data, in actual projects, there are differences in the understanding and filling methods of fields and formats among all parties. There are often mapping deviations or missing data between model data and table data, making it difficult to achieve automated import into the owner's operation and maintenance system.

[0006] (3) The data required for operation and maintenance are scattered among multiple parties such as design, construction, and equipment supply, and there is a lack of refined role-based task allocation and tracking mechanisms, resulting in unclear responsibility boundaries and high follow-up costs during the delivery phase. Although most existing collaborative tools can provide model viewing and issue ticket functions, they lack support for "attribute levels for operation and maintenance, role-based distribution and real-time verification".

[0007] (4) The existing delivery process has deficiencies in terms of consistency of model attribute data, verification of real-time collaborative input, and continuous maintenance of data after delivery, which hinders the long-term effective use of BIM in the operation and maintenance phase. Summary of the Invention

[0008] The technical problem to be solved by this invention is to provide a Web-based method, device and storage medium for collaborative delivery of BIM operation and maintenance model attribute data, which addresses the above-mentioned deficiencies of the prior art and is geared towards delivery at the operation and maintenance attribute level while also taking into account role-based collaboration, thereby improving delivery efficiency.

[0009] It also meets the requirements for standardized data export, improving the completeness of delivered data.

[0010] Finally, it clearly defines the division of delivery responsibilities and has anti-tampering functions to facilitate data management and maintenance.

[0011] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A web-based method for collaborative delivery of BIM operation and maintenance model attribute data includes: S1 generates attribute templates for the fields required for completion and handover according to the BIM component type, and uniquely assigns each subset of the attribute template to each party to form a role attribute subset correspondence table. S2 uses GUIDs to map BIM components to empty tables of attribute templates, creates delivery projects, and generates non-overlapping write tasks and role permissions. S3 is configured so that each party logs in via the web interface, locates the component, fills in the attribute information and uploads the file document. Distributed locks are used to exclusively control concurrent write requests to the same component and to verify the integrity and standard format of the fields in real time. S4 triggers containerized batch tasks by data review instructions, converts BIM models and attribute information into operation and maintenance tables and marks missing items, generates a compressed delivery package containing a lightweight BIM model, attribute mapping file and interface document that retains GUID, and writes the package digest to the blockchain network.

[0012] In the above technical solution, in S1, the attribute template sets the equipment parameters, location information, maintenance information, associated attributes, and archive documents as required fields.

[0013] In the above technical solution, in S1, BIM components are generally equipment components, and the component types include, but are not limited to, mechanical equipment and electrical equipment.

[0014] In the above technical solution, in S2, the task is based on the attribute information set of a single component.

[0015] In the above technical solution, in S2, the GUID of each component is mapped one-to-one with the empty table after the attribute template is instantiated to create an operation and maintenance delivery project.

[0016] In the above technical solution, in S2, the system generates non-overlapping write tasks for each participant based on the role attribute subset correspondence table, and binds role-level operation permissions so that different attribute subsets of the same component can only be supplemented by the specified role; a role does not have the permission to modify the content delivered by other roles.

[0017] In the above technical solution, in S3, the archive documents are unstructured attachments attached to the components, including but not limited to equipment manuals, factory certificates of conformity, warranty certificates, installation / commissioning records, acceptance forms, spare parts lists, vulnerable parts catalogs, maintenance contracts, manufacturer contact person business cards, software firmware, drivers, emergency response plans, and safety data sheets.

[0018] In the above technical solution, in S3, the system is set to only perform format and size checks on the archive document. The document itself is stored as a segmented direct transmission object, and the returned URL is written to the corresponding component attribute bar.

[0019] In the above technical solution, in S3, 3D model interactive software is used to locate the components.

[0020] In the above technical solution, step S4 involves converting the BIM model and attribute data into an operation and maintenance table according to international standards for building information exchange (ISO 16739, or IFC standards), and marking missing or erroneous items. Examples include the COBie standard, an international standard for building information exchange for facility operation and maintenance under the ISO 16739 framework. Alternatively, it could be the BCF (BIM Collaboration Format) standard, or GB / T 51447-2022 "Standard for Building Information Model Storage," etc.

[0021] In the above technical solution, in S4, the project manager of the design party issues a single trigger event command on the Web terminal. After parsing, the event is used to start the containerized batch task.

[0022] In the above technical solution, in S4, after the containerized batch task is triggered by the Web client, the container delivery image reads the lightweight BIM stream through the mounted model parsing plugin, and associates the attribute data with the model geometry using the component GUID as the key, thereby completing the automatic association with the BIM model.

[0023] In the above technical solution, in S4, after the entire byte stream of the compressed delivery package is hashed to generate a package digest, it is written into the read-only block of the consortium blockchain by calling the blockchain anchor contract interface.

[0024] Based on the above method, the present invention also provides: An electronic device includes a processor, a memory, and a program stored in the memory and executable on the processor, wherein the program, when executed by the processor, performs the steps of any of the methods described above.

[0025] A computer-readable storage medium storing a program that, when executed by a processor, implements the steps of any of the methods described above.

[0026] In summary, this invention provides a method and system for collaborative delivery of BIM operation and maintenance model attribute data based on Web technology. This system enables streamlined, standardized, and interactive multi-party collaborative delivery of operation and maintenance models, including: S1: Establishing delivery standards and a delivery responsibility system for operation and maintenance model attribute data; S2: Creating operation and maintenance delivery projects; assigning project members and setting permissions and operational scopes; S3: Multiple parties log in and collaboratively fill out forms online using the model interaction and positioning function; S4: Reviewing delivery content and integrating and delivering model data.

[0027] According to the above scheme, in step S1, the BIM attribute data delivery standard refers to the fields and values ​​of BIM attributes that need to be transferred to the building user upon completion, extracted based on the actual needs of the building operation and maintenance phase. These include key attributes such as equipment parameters, location information, maintenance information, related attributes, and archive documents. The delivery responsibility system refers to the division of delivery responsibility boundaries and content among the participating parties based on the data and document tasks in the attribute delivery standard.

[0028] According to the above scheme, in step S2, the as-built model that needs to have its operation and maintenance attribute data entered is selected, and an operation and maintenance delivery project is created on the platform. The system creates a task to be delivered according to the attribute data delivery standard. The task is based on the attribute information set of a single component, and a mapping relationship is formed between the GUID and the BIM component.

[0029] Furthermore, in step S2, accounts are created and permissions are assigned to personnel involved in the delivery project. Permissions are divided according to the roles of the participants, including designers, construction companies, equipment manufacturers, operation and maintenance platform builders, and owners. Different roles will be assigned different attribute data delivery tasks, and one role does not have the right to modify the delivery content of other roles.

[0030] According to the above scheme, in step S3, each participating party logs in and views the assigned operation and maintenance attribute information delivery tasks through the web interface. These tasks include form completion and file upload. Through the model structure tree and 3D model interaction functions, visual positioning and rapid verification are achieved, improving the accuracy of data entry and inspection. The system verifies data integrity and format specifications in real time, prompting for missing or incorrect information. A unique BIM model component ID (GUID) associates the entered operation and maintenance attribute information with each BIM model component.

[0031] According to the above scheme, in step S4, after completing the collection of data from multiple parties, the operation and maintenance delivery project manager reviews the data and generates a complete operation and maintenance model deliverable. The deliverable includes complete attribute data documents, a lightweight BIM model, and interface documents, which the owner can continue to use and update in the operation and maintenance platform.

[0032] Compared with the prior art, the beneficial effects of this invention are: (1) Improved the completeness and accuracy of operation and maintenance attribute information delivery. Adopted a three-element binding of "GUID-attribute template-role lock" and real-time verification before writing. By clarifying the tasks and boundaries of each participant, it ensures that the key attribute data required for operation and maintenance (such as equipment parameters, location information, maintenance information and archive documents) can be collected and delivered completely and accurately, avoiding information loss or redundancy, thereby realizing the standardized conversion from the as-built model to the operation and maintenance model. The attribute completeness rate increased from the industry average of <70% to 100%, eliminating the need for secondary data entry.

[0033] (2) This invention realizes multi-party collaboration and low-threshold operation. The Web platform supports online collaborative filling of operation and maintenance attribute data by all participating parties. It supports mobile terminals and client terminals. By utilizing the interactive positioning function of 3D model and model structure tree, it realizes rapid verification and visualization operation, improves data entry and inspection efficiency, and enables all parties to participate in data entry and verification with low threshold, high efficiency and strong collaboration.

[0034] (3) This invention provides standardized process management. Through standardized and process-oriented data delivery management tools, the work of design, construction, equipment manufacturers and operation and maintenance platform builders is managed in a unified manner, so as to realize standardized data entry, real-time verification and unified review.

[0035] For example, a software platform like the FM (Facilities Management System) used by property owners or maintenance units to "manage buildings, equipment, and maintenance" requires information such as the maintenance cycle, supplier contact information, and spare parts list for each piece of equipment. The COBie spreadsheets output by this invention can be directly imported into the FM system, achieving one-click integration of "as-built data" and "maintenance data." By using containerized COBie batch tasks to automatically map fields and codes, the conversion error is <0.1%, replacing manual table conversion and increasing the FM system import success rate from 60% to >99%.

[0036] (4) This invention saves delivery costs and improves delivery efficiency. It integrates information from multiple parties into a unified platform, reduces communication costs and information traceability costs, improves collaboration efficiency, solves the problems of scattered data and low collaboration efficiency, significantly improves the delivery efficiency of BIM operation and maintenance models, reduces costs, and improves the quality of model delivery.

[0037] (5) This invention is based on the principle of concurrency control: distributed lock + message bus realizes "only one role writes the same component at the same time", the conflict rate is reduced to 0, and the problem of data loss due to concurrency overlay in traditional offline Excel is solved.

[0038] (6) Version solidification principle: The blockchain anchor packet digest is stored in a hash chain. Any subsequent byte modification will invalidate the digest. After the task is submitted within the delivery cycle, the delivered version cannot be tampered with and can be traced in seconds. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] Example 1 See Figure 1 The present invention proposes an online collaborative delivery method and system for BIM operation and maintenance model information based on Web technology, comprising the following steps: S1: Based on the full lifecycle information required for building operation and maintenance, organize the basic BIM attribute set and define the attribute fields and attribute value formats.

[0049] S11: Refine the BIM attribute set requirements according to different equipment types. For example, pumps and fans have different requirements for equipment parameters and document types. In the end, each type of equipment corresponds to a BIM attribute set template.

[0050] S12: Divide the BIM attribute set into subsets according to the actual engineering logic and define the responsibility role corresponding to each subset. For example, the supplier is responsible for the equipment parameter subset in the attribute set, and the designer is responsible for the associated equipment subset in the attribute set.

[0051] S2: Select an as-built model, create an operation and maintenance attribute collaborative delivery project. During creation, call the attribute template based on equipment classification and create an empty table of tasks to be delivered. At this time, the attribute set of a single device is mapped to the GUID of the BIM model component. The purpose is to achieve the model interactive positioning effect during subsequent collaborative data entry.

[0052] S3: Create project participants and assign roles to each member. Roles include designer, contractor, owner, and supplier. After logging into the system, each member obtains delivery tasks based on their role. Delivery tasks are subsets of attributes. For example, after a supplier logs in, they select a water pump device, and the content they need to deliver is a subset of the water pump device parameters in the attribute set.

[0053] S4: All participating parties log in to the system simultaneously to complete their respective delivery tasks.

[0054] S41: Participants log in to the system, operate the model's structure tree, first filter the floors to be delivered and managed, and the BIM model on the page displays the corresponding floor. Click on the equipment in the floor structure tree to locate it, and the BIM model on the page centers the corresponding equipment. Drag the model to perform visual positioning and verification.

[0055] The model's structure tree: A collapsible directory tree (the common left-hand column in a browser) that breaks down the BIM model into "space-system-component" levels, including: Root node: Floor / Area; Intermediate nodes: System (water supply, air conditioning, electrical); Leaf node: Specific components (pump P-01, fan AHU-03, etc.); Each leaf node has a corresponding GUID; when a user clicks on any node in the tree, the 3D view immediately centers and highlights that component, and a property entry panel pops up, realizing three-way linkage between "catalog-model-data".

[0056] S42: After verification, proceed to the information entry page. On this page, complete the task of delivering your device attribute information, including filling in the attribute form and uploading related documents. After completion, switch devices to continue entering information. After completing the floor task, repeat the S41 process until all tasks are completed.

[0057] S5: After all parties have filled in the information, the operation and maintenance delivery project manager logs into the system to review the delivery content and integrate and deliver the model data.

[0058] S51: The project manager uses the model's interactive positioning function to view the completeness and quality of the deliverables from each participant and to propose modifications.

[0059] S52: After confirming that the delivered content is correct, the operation and maintenance model deliverables are generated through the delivery management function, including complete attribute data documents, lightweight BIM models and interface documents, for the owner to continue to use and update in the BIM operation and maintenance platform.

[0060] Any web-based BIM platform that supports "model lightweighting, attribute editing, role permissions, and API scheduling" can be used to implement the method of this invention. Examples include Autodesk Forge / BIM 360, Bentley iModel.js / ProjectWise, Trimble Connect, Glodon GBIM Collaboration Platform, Glodon BIMFace, Luban BIM Cloud, and ZWCloud-BIM. Its applicability is very broad.

[0061] Example 2 The Dassault Systèmes 3Dexperience platform was selected as the basic platform for implementing the method of this invention.

[0062] by Figure 2 The image shows the operation and maintenance delivery project creation page. On the right, select and open the as-built model that needs to be delivered and managed. On the left, create the project. During creation, the system extracts the GUID and equipment type of the BIM components, calls the preset attribute set template, and creates an empty table for the delivery project.

[0063] The completed project will look like this: Figure 3 As shown, there are BIM model structure trees, attribute information entry pages, and model interaction pages. The information entry page displays the delivery tasks to be completed for each individual device, including various attributes of the component and the required documentation. Information for the same component requires collaboration from multiple stakeholders (roles).

[0064] like Figure 4As shown, before the official delivery begins, the operations and maintenance delivery project manager also needs to create accounts for the collaborating participants in this project, including usernames and user roles. For example, an account can be created for the construction unit's participant, named "Construction Unit Lao Li," with the user role "Construction Party."

[0065] The pages displayed after each participant logs into the system are as follows: Figure 5 As shown, by selecting a component or device to be managed in the left-hand structure tree, the model can be centered in the right-hand model panel, or dragged to view its spatial relative position. On the middle page, selecting the information entry tab allows you to view your account's role and the attribute information and delivery tasks assigned to the device. You can complete the entry by filling in forms and uploading files.

[0066] After all participants have completed their submissions, the project manager logs into the system to check the progress of data delivery and verify the data quality. Figure 6 As shown.

[0067] After verification, the project manager integrates the model and data into the system to form the final deliverable, such as... Figure 7 As shown, this includes a lightweight BIM model that forms a complete data package, can be used in the operation and maintenance platform after format conversion, and interface documents for the operation and maintenance platform builder to perform subsequent integration, such as... Figure 8 As shown.

[0068] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
