The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention.
As shown in fig. 1 and 2, in a first aspect, an embodiment of the present invention provides a collaborative design method for a power transformation project in a multi-source heterogeneous model environment, including the following steps:
s1, developing a model conversion service, uniformly converting the multi-element heterogeneous models with different formats into cos formats to obtain cos submodels, and establishing a data base for the intercommunication of the multi-element heterogeneous models; the model conversion service is divided into a Revit cos model conversion service and a Microstation cos model conversion service.
Take the Revit cos model transformation service as an example. The method comprises the steps that a Revit environment is installed in a server, conversion service exists in a Windows service form, geometric information and attribute information of a transformer substation model are accessed through a Revit C # SDK, and the geometric information and the attribute information are converted into lightweight model data through a lightweight conversion module. The lightweight model data is data which can be identified based on WebGL and is subjected to multi-layer optimization, such as geometric optimization and LOD layered loading optimization.
As an example of the present invention, the multiple heterogeneous models with different formats include multiple heterogeneous models with formats of rvt and dgn, the cos format is a lightweight process for rvt and dgn formats, and is convenient for loading, displaying and processing on various devices such as web, mobile phone, tablet, large screen and touch terminal, and the cos and the conversion relationship and processing process of each format are shown in fig. 2.
As shown in fig. 3, the multivariate heterogeneous models with different formats are uniformly converted into cos format by the following method:
and S11, removing redundant data in the multi-element heterogeneous models with different formats.
And S12, eliminating invalid information links in the multi-element heterogeneous models with different formats.
S13, aiming at the multi-element heterogeneous model obtained in the two steps, carrying out lightweight processing on the geometric shape control parameters of the multi-element heterogeneous model based on an octree structure; under the octree structure lightweight algorithm, the core characteristic points and geometric parameters of the multi-element heterogeneous model are not lost, model information is organized in the form of octree, and traversal of the information is performed according to breadth-first grading, so that lightweight on efficiency rather than absolute data is realized, and the overall cooperation efficiency is improved.
And S14, performing the same entity component merging treatment on the lightweight multi-element heterogeneous model to obtain a cos submodel. The component merging processing means that components with completely consistent core geometric parameters and accessory information are stored in an address unit and are displayed in a form similar to pointer reference when needed, so that the storage space is saved, and the transmission efficiency is optimized.
And S2, developing a positioning rule configuration module, establishing a global coordinate system, and establishing a positioning coordinate basis for automatic assembly of the multi-source heterogeneous model. The unified coordinate is the basis of model assembly, the coordinate system is not limited to a certain standard, and can be changed according to the specific conditions of the project, but is not modified once determined.
As shown in fig. 4, a global coordinate system is established, and a splicing operation is preset, the method is as follows:
and S21, setting a global coordinate system, such as a geodetic 2000 coordinate system.
S22, converting the local coordinate system of the single cos submodel into a global coordinate system;
and S23, setting splicing operations based on a coordinate system, including translation, rotation, scaling and mirror image.
Specifically, positioning points of the sub cos model based on the global coordinate system are picked up, a rotation angle is set through dragging, a static scaling factor and whether mirror image operation is performed are set again, and finally coordinate system transformation operation is performed based on a rotation matrix.
And S3, developing a multi-model self-assembly module, integrating multi-source heterogeneous models under multiple specialties, multiple directions and different time periods, and assembling different cos submodels based on a global coordinate system to form a total cooperation model.
In this embodiment, an assembly meta operation is defined, which includes: and translation, rotation, scaling, mirroring, and finally assembling the submodels into a finished product cooperative assembly model based on various combinations of element operations.
As shown in fig. 5, different cos submodels are assembled, and the specific method is as follows:
s31, establishing a database table, and presetting the assembling logic process of each cos submodel in the database table; the assembly model and the submodels form a tree structure, and the submodels can be nested. And defining an element operation process when adding the sub-model, and combining a plurality of sub-model lightweight data with respective series of element operations to form the assembly or assembly logic of the model. The whole assembly logic is recorded, the subsequent design change can be automatically applied without resetting, the communication cost increase caused by frequent design change is greatly saved, the error probability is reduced, and the design quality is improved.
And S32, dynamically assembling the cos submodel based on the assembling logic process.
S4, developing a sub-model change reminding module, so that multi-party cooperation is more timely and effective, and the unique identifier MD5 code of the sub-model is automatically updated along with the change of the file; if the cos submodel uniqueness mark MD5 code changes, the trigger of the updated database triggers an updating action, the total cooperation model is automatically updated, and the system service learns the updating event and executes the module code to inform the model designer in the form of system popup and WeChat messages. The notification action can be extended continuously, such as adding a short message reminder, qq reminder, and the like.
And S5, a development condition diagram extraction module performs condition diagram extraction on the total cooperation model to generate a local contribution model. And the investment can be automatically increased according to the target requirement, and a more complex multi-party collaboration scene is realized. The condition graph extraction is based on one application in a responsible collaboration environment, such as a multi-professional collaboration scene in the fine and complex engineering situation. The key of condition graph extraction is to remember the rules or standards of the target party for model consumption and translate the rules or standards into operations which can be understood by the system, so that detailed requirements do not need to be repeatedly informed when investment improvement requirements exist, and the requirements can be directly generated and extracted, and particularly under the condition of frequent engineering, communication cost can be greatly saved, and design quality is improved.
As shown in fig. 6, the method specifically includes the following steps:
and S51, establishing a database table, and describing the condition chart extraction requirements of the downstream partner (or a certain specialty).
S52, before the cos data is converted, the original model is subjected to a condition map extraction process.
And S53, assembling based on the extracted condition diagram to form an assembly model meeting the downstream conditions.
And S54, sending the finished product assembly model to a downstream professional.
Each industry and its specialty has its own requirements for geometric range of models, accuracy, compliance, etc., which are consolidated into a database and associated with the funding process. The program can understand the requirement rule of the condition diagram and convert the requirement rule into an operable command, and performs the actions of extraction, compliance check, element basic operation and the like from the original model, thereby completing the automatic conversion from the integral model to the local contribution model and further realizing the dynamic extraction of the condition diagram.
