Description

Technical Field

[0001] The present invention relates to the technical field of BIM model design, and in particular to a collaborative design system based on BIM technology. Background Art

[0002] BIM (Building Information Modeling) uses all relevant data about a construction project as its foundation to create a building model. It uses digital information to simulate real-world building information, including 3D geometry and information such as the materials, properties, price, weight, location, and schedule of building components. Revit is an architectural design and modeling software specifically designed for creating and managing BIM data. In Revit, you can create a complete BIM model, including the geometry, attributes, construction information, and annotations of building elements. It allows construction professionals to create, edit, and analyze these BIM models.

[0003] In the existing technology, designers design models in the Revit client, but reviewers cannot view the models and make three-dimensional annotations to the models in a timely and effective manner in the task management system. This annotation information is isolated from the data of the Revit modeling tool, resulting in designers being unable to determine the final version of the model in a timely manner, leading to low production efficiency. Summary of the Invention

[0004] In view of this, it is necessary to provide a collaborative design system based on BIM technology to solve the problem of low production efficiency caused by the inability of instant communication between the client and the task management system.

[0005] In order to solve the above problems, in a first aspect, the present invention provides a collaborative design system based on BIM technology, comprising: The project planning module is used to set the units included in the target project and the professional categories corresponding to the units, set the professional group members of each professional in the professional category and the permission types of professional group members, generate a shared folder based on the preset building information model template, create a shared subdirectory corresponding to the unit model in the shared folder, and assign Windows access rights to the shared subdirectory to professional group members; The collaborative design module is used to obtain the work sets determined by clients of different permission types through preset plug-in site messages, and synchronize the work sets to the corresponding shared subdirectories; The lightweight service module is used to lightweight the monomer model in the shared subdirectory to obtain lightweight files.

[0006] In a possible implementation, the permission type includes one or more of: project manager permission, professional person in charge permission, designer permission, and reviewer permission.

[0007] In a possible implementation, the preset building information model template includes one or more of a Revit standard single template, a Rhino standard single template, a Bentley standard single template, a Tekla standard single template, and an ArchiCAD standard single template.

[0008] In a possible implementation, the lightweight file is in mv format.

[0009] In a possible implementation, the project planning module is also used for automatic distribution of standardized templates and version control of standardized templates.

[0010] In one possible implementation, the collaborative design module is used to: Obtaining a first confirmation message and sending the first confirmation message to the client with reviewer authority, wherein the first confirmation message is a confirmation message after the client with designer authority completes the operation on the target monomer model; Generate a second confirmation message based on the first confirmation message, where the second confirmation message is a confirmation message that the client with professional person in charge authority submits the target monomer model to the lightweight service module; The second confirmation message is sent to the client with project manager authority, so that the client with project manager authority performs a closing operation on the target monomer model.

[0011] In a possible implementation, the collaborative design module is further configured to synchronize the workset to a corresponding shared subdirectory through real-time synchronization, scheduled synchronization, or custom synchronization.

[0012] In a possible implementation, the collaborative design module uses a difference block transfer protocol to implement incremental synchronization of the monomer model.

[0013] In a possible implementation, a client is further included, and the client is used to modify the target monomer model to obtain a modified target monomer model, and synchronize the modified target monomer model to the collaborative design module.

[0014] In a possible implementation, the client is configured to modify the target monomer model to obtain a modified target monomer model, including: The client is used to modify the position and size of the elements in the target monomer model to obtain a modified target monomer model.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] In the description of the embodiments of the present invention, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone.

[0019] The terms "first," "second," and so on, used in the embodiments of the present invention are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, technical features designated as "first" or "second" may explicitly or implicitly include at least one such feature.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] Before presenting the embodiments, the following terms are explained.

[0022] Autodesk Revit software is built specifically for Building Information Modeling (BIM). BIM is an integrated process built on coordinated, reliable project information from design to construction to operations. By adopting BIM, construction companies can design and develop innovative projects using consistent information throughout the entire process. They can also support better communication by accurately visualizing the building's appearance and simulate real-world performance to help all parties understand cost, schedule, and environmental impact.

[0023] The present invention provides a collaborative design system based on BIM technology, which is described below.

[0024] Figure 1 This is a system architecture diagram of an embodiment of the collaborative design system based on BIM technology provided by the present invention, as shown in FIG. Figure 1 As shown in the figure, the collaborative design system based on BIM technology includes: The project planning module 101 is used to set the units included in the target project and the professional categories corresponding to the units, set the professional group members of each professional in the professional category and the permission types of the professional group members, generate a shared folder based on a preset building information model template, create a shared subdirectory corresponding to the unit model in the shared folder, and assign Windows access permissions to the shared subdirectory to the professional group members; It should be noted that project units include, for example, a guardhouse, a material supply station, a container repair and cleaning workshop, an upper lockhead-hoisting and closing machine room, an east line-ship lock, a west line-ship lock, and so on. It is understood that project units may also include other components. Examples of disciplines include, but are not limited to, engineering mechanics, engineering surveying, and structural mechanics. Units and their corresponding professional categories can be understood as follows: for example, a guardhouse unit can belong to both engineering mechanics and engineering surveying.

[0025] It should be noted that the meaning of assigning Windows access rights to shared subdirectories to professional group members is: each target project corresponds to a target folder, and the target folder contains the individual models of the target project. Therefore, the Windows access rights of professionals to the target folder are set. For example, the corresponding group or user names under the target file include Zhang San, Li Si, Wang Wu and Zhao Liu. The group can be set to have modification permissions, read permissions, write permissions, and list folder contents permissions on the target folder.

[0026] The collaborative design module 102 is used to obtain the work sets determined by clients of different permission types through preset plug-in site messages, and synchronize the work sets to corresponding shared subdirectories; It should be noted that a workset refers to the artificial classification of elements in the model according to work habits in BIM software, so that the display of different elements can be controlled by the workset, enabling simultaneous collaborative design by multiple people (multiple people working on a three-dimensional model at the same time), and real-time feedback of other people's modification results to all designers involved in the design.

[0027] The lightweight service module 103 is used to lightweight the monomer model in the shared subdirectory to obtain a lightweight file.

[0028] Compared with the prior art, this embodiment provides a collaborative design system based on BIM technology, a project planning module for setting the monomers included in the target project and the professional categories corresponding to the monomers, setting the professional group members of each profession in the professional category and the permission types of the professional group members, generating a shared folder based on a preset building information model template, and creating a shared subdirectory corresponding to the monomer model in the shared folder, assigning windows access rights to the shared subdirectory to the professional group members, thereby realizing access rights of different permissions to different monomer models and ensuring the security of the files; a collaborative design module for obtaining the working set determined by the client with different permission types through the preset plug-in site message, and synchronizing the working set to the corresponding shared subdirectory, thereby improving the efficiency of collaboration; a lightweight service module for lightweighting the monomer model in the shared subdirectory to obtain a lightweight file. The present invention realizes timely mutual communication between clients with different permission types through the preset plug-in site message, thereby improving production efficiency.

[0029] In some embodiments of the present invention, the permission type includes one or more of: project manager permission, professional person in charge permission, designer permission, and reviewer permission.

[0030] In some embodiments of the present invention, the preset building information model template includes one or more of: a Revit standard single template, a Rhino standard single template, a Bentley standard single template, a Tekla standard single template, and an ArchiCAD standard single template.

[0031] In some embodiments of the present invention, the format of the lightweight file is mv format.

[0032] In some embodiments of the present invention, the project planning module 101 is also used for automatic distribution of standardized templates and version control of standardized templates.

[0033] In some embodiments of the present invention, the collaborative design module 102 is used to: Obtaining a first confirmation message and sending the first confirmation message to the client with reviewer authority, wherein the first confirmation message is a confirmation message after the client with designer authority completes the operation on the target monomer model; Generate a second confirmation message based on the first confirmation message, where the second confirmation message is a confirmation message that the client with professional person in charge authority submits the target monomer model to the lightweight service module; The second confirmation message is sent to the client with project manager authority, so that the client with project manager authority performs a closing operation on the target monomer model.

[0034] In a specific embodiment of the present invention, Figure 2 The following is a collaborative flow chart of the collaborative design system. The specific process of this system is as follows: Step 1: If Figure 3 The figure shows a flowchart of people with project manager permissions in the collaborative design system. The project manager, i.e., a person with project manager permissions, sets the corresponding units and the disciplines associated with the units in the collaborative design system, sets the members of the relevant discipline group, selects a unified standard unit Revit template file, creates a shared folder and synchronizes the unit file with one click, creates active workgroups with different roles under different disciplines for the unit file, and assigns Windows access rights to the shared directory to the members of the relevant discipline group. Step 2: After logging into the Revit plug-in, a professional team member with professional leader authority selects the corresponding project and implements permission control based on the role in the project unit. If the professional leader is authorized, he or she can issue design tasks to the designers in the professional team and designate reviewers for the design tasks. If the designer is authorized, he or she can receive the single design task and activate the personal workgroup. After completing some components, the design part will be synchronized to the central file and the plug-in will be used to send message notifications. The reviewers will conduct the review after receiving the notification. Step 3: After receiving the review comments, the reviewer uses the plug-in to batch select Revit elements and uses the area screenshot tool provided by the plug-in to describe the problematic components within the selected range. The reviewer then sends the comments to the designer. The designer clicks the message in the plug-in message bar to automatically synchronize the latest central file content, highlight the Revit elements marked in the review comments, calculate the central view position, and then reposition the camera. Step 4: If Figure 4 As shown in the figure, when all professional tasks are completed, the Revit plug-in will push the completion message of the single professional task to the professional person in charge (the professional is distinguished according to the activity group naming of Revit). The professional person in charge clicks the message and the professional model submission window automatically pops up. Click to lightweight. The plug-in automatically highlights the professional components involved in the single unit and converts them into lightweight intermediate files in .mv format. The shared file address of the professional task and its lightweight .mv file is submitted to the design management system. Step 5: The collaborative design system clicks on the corresponding design task result to automatically trigger the download file to the conversion service action, achieve lightweighting, obtain the final lightweight address, and push it to the project manager's workspace.

[0035] Step 6: After all disciplines in the unit have completed their professional tasks and submitted them, the Revit plug-in will push the unit completion message to the project manager. After checking the entire unit file, the project manager clicks "Close" to revoke the write permissions of all professionals involved through the plug-in, and persist all operation permission histories. It can also be activated and restored to the specified permission version if needed later.

[0036] In some embodiments of the present invention, the collaborative design module 102 is further configured to synchronize the workset to a corresponding shared subdirectory through real-time synchronization, scheduled synchronization, or custom synchronization.

[0037] In a possible implementation, the collaborative design module uses a difference block transfer protocol to implement incremental synchronization of the monomer model.

[0038] In a possible implementation, a client is further included, and the client is used to modify the target monomer model to obtain a modified target monomer model, and synchronize the modified target monomer model to the collaborative design module.

[0039] In a possible implementation, the client is configured to modify the target monomer model to obtain a modified target monomer model, including: The client is used to modify the position and size of the elements in the target monomer model to obtain a modified target monomer model.
