[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0043] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0044] like Figure 1 and 2 As shown, in a first aspect of an embodiment of the present invention, a method for collaborative design of a substation project in a multi-source heterogeneous model environment is provided, comprising the following steps:

[0045] S1. Develop model conversion services to uniformly convert multi-source heterogeneous models of different formats into cos format to obtain cos sub-models, and establish a data foundation for the intercommunication of multi-source heterogeneous models; model conversion services are divided into Revit cos model conversion services and Microstation cos model conversion services.

[0046] Take the Revit cos model conversion service as an example. The Revit environment is installed on the server, and the conversion service exists in the form of Windows service. The geometric information and attribute information of the substation model are accessed through the Revit C# SDK, and then converted into lightweight model data through the lightweight conversion module. The lightweight model data is based on data that can be recognized by WebGL and has undergone multiple layers of optimization, such as geometry optimization, LOD layered loading optimization, etc.

[0047] As an example of the present invention, the multi-heterogeneous models in different formats include multi-heterogeneous models in *.rvt and *.dgn formats. The cos format is a lightweight processing of the rvt and dgn formats, which is convenient for loading, displaying and processing on a variety of devices such as web, mobile phones, tablets, large screens, touch terminals, etc. The conversion relationship and processing process of cos and various formats are as follows: Figure 2 shown.

[0048] like Figure 3 As shown, the multivariate heterogeneous models in different formats are uniformly converted into the cos format as follows:

[0049] S11. Eliminate redundant data in multivariate heterogeneous models of different formats.

[0050] S12. Eliminate invalid information links in multivariate heterogeneous models of different formats.

[0051] S13. For the multi-source heterogeneous model obtained in the above two steps, lightweight processing is performed on the geometric shape control parameters of the multi-source heterogeneous model based on the octree structure. Under the octree structure lightweight algorithm, the core feature points and geometric parameters of the multi-source heterogeneous model are not lost. The model information is organized in the form of an octree, and the traversal of the information is performed in a breadth-first hierarchical manner, thus achieving lightweight in terms of efficiency rather than absolute data, and improving the overall collaboration efficiency.

[0052] S14. Perform identical entity component merging processing on the lightweight processed multi-source heterogeneous model to obtain the cos sub-model. Component merging processing means storing components with exactly the same core geometric parameters and affiliated information in one address unit and displaying them in the form of "pointer reference" when needed, thus saving storage space and optimizing transmission efficiency.

[0053] S2. Develop a positioning rule configuration module, establish a global coordinate system, and establish a positioning coordinate basis for the automatic assembly of multi-source heterogeneous models. Unified coordinates are the basis for model assembly. The coordinate system is not limited to a certain standard and can be changed according to the specific situation of the project, but once determined, it will not be modified again.

[0054] As Figure 4 shown, establish a global coordinate system and preset the assembly operation. The method is as follows:

[0055] S21. Set the global coordinate system, such as the Earth 2000 coordinate system.

[0056] S22. Convert the local coordinate system of a single cos sub-model to the global coordinate system;

[0057] S23. Set the assembly operations based on the coordinate system, including translation, rotation, scaling, and mirroring.

[0058] Specifically, first pick the positioning points of the sub-cos model based on the global coordinate system, secondly set the rotation angle by dragging, then set the static scaling factor and whether to perform mirroring operations, and finally perform coordinate system transformation operations based on the rotation matrix.

[0059] S3. Develop a multi-model self-assembly module, integrate multi-source heterogeneous models under multiple specialties, multiple parties, and different time periods, and assemble different cos sub-models based on the global coordinate system to form a total collaboration model.

[0060] In this embodiment, assembly meta-operations are defined, including: translation, rotation, scaling, and mirroring. Based on various combinations of the meta-operations, the sub-models are finally assembled into a finished product collaboration assembly model.

[0061] As Figure 5 shown, assemble different cos sub-models. The specific method is as follows:

[0062] S31. Establish a database table and preset the assembly logic process of each cos sub - model in the database table; assemble the model and sub - models to form a tree - like structure, and the sub - models can also be nested. Define the meta - operation process when adding sub - models. The lightweight data of multiple sub - models combined with their respective series of meta - operations constitute the assembly or composition logic of the model. The entire assembly logic is recorded, and future design changes will be automatically applied without re - setting, greatly saving the increased communication costs caused by frequent design changes, reducing the error probability, and improving the design quality.

[0063] S32. Dynamically assemble the cos sub - models based on the above - mentioned assembly logic process.

[0064] S4. Develop a sub - model change reminder module to make multi - party collaboration more timely and effective. The unique identifier MD5 code of the sub - model is automatically updated as the file changes; if the MD5 code of the unique identifier of the cos sub - model changes, the trigger in the updated database triggers an update action, then the total collaboration model is automatically updated, and the system service, upon learning of the update event, simultaneously executes the module code to notify the model designer in the form of a system pop - up window and a WeChat message. The notification action can be further extended in the future, such as adding SMS reminders, QQ reminders, etc.

[0065] S5. Develop a conditional graph extraction module to extract conditional graphs from the total collaboration model to generate a partial information - providing model. It can automatically provide information according to the target requirements, realizing more complex multi - party collaboration scenarios. Conditional graph extraction is an application based on a responsible collaboration environment, such as a multi - professional collaboration scenario in a fine and complex engineering situation. The key to conditional graph extraction is to "remember" the rules or standards for model consumption by the target party and translate the rules or standards into operations that the system can understand. In this way, every time there is an information - providing requirement, there is no need to repeatedly inform the detailed requirements, and it can be directly generated and extracted. This can greatly save communication costs and improve design quality, especially in the case of frequent engineering projects.

[0066] As Figure 6 shown, it specifically includes the following steps:

[0067] S51. Establish a database table to describe the conditional graph extraction requirements of downstream cooperation parties (or a certain specialty).

[0068] S52. Perform conditional graph extraction processing on the original model before converting cos data.

[0069] S53. Assemble based on the extracted conditional graphs to form an assembly model that meets the downstream conditions.

[0070] S54. Send the finished product assembly model to the downstream specialty.

[0071] Each industry and its specialty have their own requirements for model geometric range, accuracy, compliance, etc. These requirements or standards are solidified in the database and associated with the information submission process. The program can understand the requirements and rules of the conditional drawing, convert them into operable commands, and perform actions such as extraction, compliance checking, and basic element operations from the original model, completing the automatic conversion from the overall model to the local information submission model, thereby realizing the dynamic extraction of the conditional drawing.

[0072] The system built based on this method can operate independently as a self - contained system or be embedded in third - party MIS, ERP, and cloud platforms to achieve collaborative design, construction, and operation and maintenance of model data.
