[0002] In computer-aided design for projects (e.g., construction projects), due to the complexity of the projects, it is usually necessary for multiple users with different domain knowledge to collaborate on multiple terminals to complete the design of the project. For example, in some conventional solutions, when using Building Information Modeling (BIM), due to the complexity of BIM data, it is usually only supported to be edited by one user at a time. Only after the user completes the editing and uploads, other users can start editing, and the corresponding BIM data is not uploaded and downloaded in time, so avoiding data conflicts caused by multiple users editing the data at the same time in this way may have many disadvantages. Therefore, there is a need for a solution that can efficiently collaborate on BIM data in a collaborative scenario of multiple terminals. Summary of the invention

[0019] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0020] The term "including" and its variations used in this document are open-ended, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment". The relevant definitions of other terms will be given in the following description.

[0021] The inventors have noticed that in order to ensure data consistency and avoid data conflicts that may be caused by multiple terminal devices, conventional methods only support BIM data being edited by a single user at the same time, so the efficiency is not high.

[0022] The inventors also noted that in some methods, for example, the server can divide the BIM data into multiple sub-files and then distribute them to multiple terminal devices, and each user can only edit the sub-file to which he is assigned to avoid potential data conflicts. After the editing is completed, each user uploads the edited sub-file to the server to merge into a complete model file. Since each user is only assigned to a part of the BIM data, the number of components that each user can edit is limited. None of the above methods can coordinate BIM data according to the component level. The collaborative efficiency of these solutions is not high and lacks flexibility. At the same time, since data transmission needs to be carried out at the order of model files when uploading, higher bandwidth and storage space are required.

[0023] In order to at least partially solve some of the above shortcomings, an embodiment of the present disclosure provides a method for real-time collaborative design of a component-based building information model. In this method, the building information model BIM data of the edited component is obtained, and the BIM data of the component comes from the first terminal device among multiple terminal devices in the real-time collaborative design; the data type corresponding to the BIM data of the edited component is queried; and according to the queried data type, the editing authority corresponding to the data type is provided to other terminal devices among the multiple terminal devices in the real-time collaborative design, wherein when the data type is a temporary data type, the data describing the attributes of the component in the data belonging to the temporary data type is transmitted to the other terminal devices, and the data describing the pixels of the component in the data belonging to the temporary data type is not transmitted.

[0024] Therefore, the method disclosed in the present invention is different from the traditional design in which editing operations can only be performed separately and step by step. Instead, the overall model can be detected and modified synchronously, and multi-terminal and multi-user synchronous execution can be realized, which not only improves the model design speed, but also greatly improves the utilization rate of personnel. In addition, due to the good real-time performance of real-time collaborative design, the user experience and sense of participation of the participants can be better. At the same time, since pixels are not transmitted, the bandwidth and storage space can be reduced. Therefore, the working principle and mechanism of the present invention are significantly different from any known method.

[0025] In the following description, some embodiments will be discussed with reference to BIM of buildings, such as schools, hospitals, etc. However, it should be understood that this is only to enable ordinary technicians in the field to better understand the principles and ideas of the embodiments of the present disclosure, and is not intended to limit the scope of the present disclosure in any way.

[0026] Figure 1 A schematic diagram of an example environment for using a method for real-time collaborative design of a component-based building information model according to certain embodiments of the present disclosure is shown.

[0027] like Figure 1As shown, at the execution subject 101 (e.g., a computer system, a server, etc.), the building information model BIM data of the edited component is obtained (e.g., received). Examples of these BIM data include, for example, model elements, temporary elements, graphic model data, non-graphic parameter data, and other forms of result data (text, pictures, XML, etc.). In some embodiments, these data can come from one or more terminal devices among the terminal devices 102, 103, and 104. Figure 2 The method proposed in the present disclosure is described below, and the terminal device 102 is selected as the terminal device. It should be understood that Figure 1 The example environment 100 shown in the example is merely illustrative and is not intended to limit the scope of the present disclosure. The example environment 100 may also include various additional devices, apparatuses, and / or modules. Figure 1 The modules shown in the figure are also only illustrative and are not intended to limit the scope of the present disclosure. In some embodiments, some modules can be integrated into one physical entity, or further split into more modules.

[0028] Figure 2 A flowchart of a method 200 for real-time collaborative design of a component-based building information model according to some embodiments of the present disclosure is shown.

[0029] For ease of description, a building will be used as an example to describe the process of the method for real-time collaborative design of a component-based building information model implemented by the method 200. However, as mentioned above, this is merely exemplary and is not intended to limit the scope of the present disclosure in any way. The embodiment of the method 200 described herein can also be used in the process of the method for real-time collaborative design of a component-based building information model in any other appropriate engineering.

[0030] like Figure 2 As shown, at box 202, the building information model BIM data of the edited component is obtained, and the BIM data of the component comes from the first terminal device among multiple terminal devices in real-time collaborative design. As an example only, the first terminal device is the terminal device 102, such as a desktop computer, a laptop computer, a mobile computing device, etc.

[0031] At block 204 , a data type corresponding to the edited BIM data of the component is queried.

[0032] The data types can be as shown in Table 1.

[0033]

[0034] Table 1

[0035] It should be noted that the term “collision check” in Table 1 refers to a check on whether operations of multiple terminal devices on the same component conflict in real-time collaborative design.

[0036] Combine the following Figure 4 The term "pixel" used in this disclosure is explained. Figure 4 A schematic diagram of pixels of a building information model according to certain embodiments of the present disclosure is shown. A pixel can be understood as a visual representation of a rendered component, and its data volume is relatively large, and can be calculated and stored in a local computer system without being transmitted. What needs to be transmitted is data describing the properties of the component, for example, information such as the length, width, and height of the component. When such data (temporary data type) is edited, only the data describing the properties of the component in the data is transmitted to other terminal devices, and the data describing the pixels of the component in the data is not transmitted. This can increase the rate, save bandwidth, and reduce latency, so that users of multiple terminal devices participating in real-time collaborative design have no visual differences, thereby improving the user experience.

[0037] Now return to Figure 2 , at box 206, based on the queried data type, editing permissions corresponding to the data type are provided to other terminal devices among the multiple terminal devices in the real-time collaborative design, wherein when the data type is a temporary data type, data describing the attributes of the component in the data belonging to the temporary data type is transmitted to the other terminal devices, while data describing the pixels of the component in the data belonging to the temporary data type is not transmitted.

[0038] In some embodiments, when the data type is a locked data type, data belonging to the locked data type can be transmitted to other terminal devices, and the data belonging to the locked data type can only be edited by the user of the first terminal device; and when the data type is a shared sequential data type, data belonging to the shared sequential data type can be transmitted to other terminal devices, and the data belonging to the shared sequential data type can be edited by the user of any terminal device among the multiple terminal devices. For example, the data of the locked data type edited by the terminal device 102 can be transmitted to the terminal device 103, for example, via the server 101, but the user of the terminal device 103 can only see but not edit the data of the locked data type. The data of the shared sequential data type edited by the terminal device 102 can be transmitted to the terminal device 104, for example, via the server 101, and the user of the terminal device 104 can see and edit the data of the shared sequential data type.

[0039] In some embodiments, the editing permission for data belonging to a locked data type may include an insert operation for synchronously presenting an object created by a user of a first terminal device on each of a plurality of terminal devices in real-time collaborative design, for example, inserting (such as adding) a component representing a wall.

[0040] In some embodiments, the editing permission for data belonging to a locked data type may also include a modification operation, which is used to synchronously present the BIM data of the component modified by the user of the first terminal device on each of the multiple terminal devices in the real-time collaborative design. For example, modifying the height of the component representing the wall to 3 meters.

[0041] In some embodiments, the editing permission for data belonging to a locked data type may also include a delete operation, which is used to synchronously delete the BIM data of a component by a user of the first terminal device on each of the multiple terminal devices in the real-time collaborative design. For example, deleting a component representing a wall.

[0042] In some embodiments, the editing permission for data belonging to a shared sequential data type may include: generating a queue describing the editing order according to the editing order of BIM data of components edited by respective users of multiple terminal devices; executing the edits corresponding to the queue according to the queue; and presenting the results of the execution of the edits corresponding to the queue events on multiple terminal devices. For example, the user of terminal device 102 performs an editing operation on a component representing a wall, which operation is a modification operation, and the data type is a shared sequential data type. Afterwards, the user of terminal device 103 also performs an editing operation on the same component, which operation is also a modification operation, and the data type is also a shared sequential data type. In this way, a queue can be generated in a sequential order, and then the corresponding operations can be executed and presented in the order of the editing operations in the queue.

[0043] Figure 3 FIG. 3 is a flowchart of a method 300 for real-time collaborative design of a component-based building information model according to some embodiments of the present disclosure. Figure 3 As shown, box 302, box 304, box 306 and Figure 2The functions of the boxes 202, 204, and 206 in the method 300 correspond one to one. For the sake of brevity, the description of boxes 302, 304, and 306 will refer to the description of boxes 202, 204, and 206. In addition, the method 300 may also include box 308. In some embodiments, at box 308, a mapping table associated with the data of the attributes of the component is created, the mapping table saves the relationship between the data of the attributes of the edited component on the first terminal device and the data of the attributes of the unedited component on the server; and in response to the request of other terminal devices, the mapping table is transmitted to the corresponding terminal device. By transmitting the mapping table, the correspondence between the data and the data attributes can be made clearer, reducing the probability of error.

[0044] In some embodiments, method 300 may further include block 310. At block 310, the edits of the respective users of the plurality of terminal devices are recorded in a log, wherein the log is stored separately from the BIM data of the component; and based on the independently stored log, the results of the execution of the edits are presented to other terminal devices in the plurality of terminal devices in the real-time collaborative design. In this way, since the log is stored separately, the fairness and traceability of the data are guaranteed, and the convenience of data maintenance is promoted. Block 310 may be automatically executed at any time and is not limited to following Figure 3 Execute in the order shown.

[0045] In some embodiments, method 300 may also include box 312. At box 312, a first BIM identifier is determined, wherein the first BIM identifier is associated with a first terminal device; a second BIM identifier is determined, wherein the second BIM identifier is associated with one of the other terminal devices; based on the first BIM identifier and the second BIM identifier being the same, it is determined that the terminal device in the other terminal devices is in real-time collaborative design; or based on the first BIM identifier and the second BIM identifier being different, it is determined that the terminal device in the other terminal devices is not in real-time collaborative design. By implementing box 312, it is possible to effectively determine whether a specific terminal device is in real-time collaborative design, thereby excluding terminal devices that are not in real-time collaborative design, making data more confidential and more secure. Box 312 can be executed automatically or upon request at any time and is not limited to following Figure 3 Execute in the order shown.

[0046] By implementing method 200 or method 300, multi-terminal multi-user synchronous execution can be achieved, which not only improves the model design speed, but also greatly improves the utilization rate of personnel. And because the real-time performance of real-time collaborative design is good, the user experience and sense of participation of the participants can be better. At the same time, since pixels are not transmitted, the bandwidth and storage space can be reduced, and the latency is reduced, so that users of multiple terminal devices participating in real-time collaborative design have no visual difference, improving the user experience. The method disclosed in the present invention does not need to make many restrictions on the terminal device in order to ensure the uniqueness of data attributes, which greatly alleviates the pressure on the client (for example, terminal devices 102-104) and solves the problem of synchronization failure caused by inconsistent data synchronization or conflict of terminal devices.

[0052] In some embodiments, editing permissions for data belonging to a locked data type may include: an insert operation, which is used to synchronously present an object created by a user of a first terminal device on each of a plurality of terminal devices in real-time collaborative design; a modification operation, which is used to synchronously present, on each of a plurality of terminal devices in real-time collaborative design, BIM data of a component modified by the user of the first terminal device; and a delete operation, which is used to synchronously delete, on each of a plurality of terminal devices in real-time collaborative design, the BIM data of a component deleted by the user of the first terminal device.

[0053] In some embodiments, editing permissions for data belonging to a shared sequential data type may include: generating a queue describing the editing order based on the editing order in which respective users of multiple terminal devices edit BIM data of components; executing edits corresponding to the queue based on the queue; and presenting the results of executing the edits corresponding to the queue events on multiple terminal devices.

[0054] In some embodiments, the editing permission providing module can also be configured to: create a mapping table associated with the data of the attributes of the component, the mapping table saves the relationship between the data of the attributes of the edited component on the first terminal device and the data of the attributes of the unedited component on the server; and in response to a request from other terminal devices, transmit the mapping table to the corresponding terminal device.

For the sake of brevity, the disclosure will not be repeated here. In addition, in some embodiments, the apparatus 600 may further include a log module 608, which is configured to record the edits of respective users of the plurality of terminal devices in a log, wherein the log and the BIM data of the component are stored separately and independently; and based on the independently stored log, the results of the execution of the edits are presented to other terminal devices among the plurality of terminal devices in the real-time collaborative design.

[0057] In some embodiments, the device 600 may also include a real-time collaborative design determination module 610, which is configured to: determine a first BIM identifier, wherein the first BIM identifier is associated with a first terminal device; determine a second BIM identifier, wherein the second BIM identifier is associated with one of the other terminal devices; based on the first BIM identifier and the second BIM identifier being the same, determine that the terminal device in the other terminal devices is in real-time collaborative design; or based on the first BIM identifier and the second BIM identifier being different, determine that the terminal device in the other terminal devices is not in real-time collaborative design.
