Description

Technical Field

[0001] The present invention relates to the technical field of engineering design, and in particular to a BIM model information synchronization method based on an open multidimensional database. Background Art

[0002] Building Information Modeling (BIM) is a new tool for architecture, engineering and civil engineering. The term Building Information Modeling or Building Information Modeling was created by Autodesk. It is used to describe computer-aided designs that are mainly based on three-dimensional graphics, object-oriented, and related to architecture. At the beginning, this concept was promoted to the public by Jerry Laiserin, who promoted the technologies provided by Autodesk, Bentley Systems, and Graphisoft. Mainstream BIM software such as Autodesk Revit and Bentley provide rich functions for adding model attribute information. These software allow users to edit and adjust a series of parameters of model data, including project parameters, shared parameters, global parameters, and component type parameters and instance parameters, to meet the needs of different users of the project at different time stages.

[0003] Currently, in the entire life cycle of a project's BIM model, including the current space information model - the overall planning information model - the detailed design information model - the design scheme information model - the engineering construction information model - the engineering completion information model, there will be exploration, planning, design, construction, and operation and maintenance engineers from different stages to edit the BIM model. Even each type of engineer is completed by multiple engineers from different office locations working together. The model editing information sent by these different access terminals is difficult to coordinate and synchronize with the project progress in a dynamic and timely manner. Summary of the invention

[0004] The purpose of the present invention is to provide a BIM model information synchronization method based on an open multidimensional database to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A BIM model information synchronization method based on an open multidimensional database comprises the following steps:

[0007] S1: Send the editing instructions of the BIM model of each access terminal to the server, triggering the server to generate model editing content and file editing content according to the model editing instructions; the BIM design software end edits the BIM model, and the editing instructions of the BIM model of each access terminal are used to edit the target BIM model; the target BIM model is the BIM model displayed on the model display page of each access terminal, the BIM design software end sends an API request to the database for database information, and the database returns the requested data, and then the BIM design software end sends an API request to the database to write information, and the database returns the write status, and at the same time the BIM design software end sends a subscription database update request to the database, and the database sends a data update broadcast to the BIM design software end; a two-dimensional drawing file associated with the target BIM model is also attached to the model display page; the model editing content corresponds to the file editing content, and the server database pushes the latest data to the client in real time through the real-time push module;

[0008] S2: The client uses the information download module to download information from the server, then uses the information editing module to edit the downloaded information, and then uses the information generation module to generate information for the edited information: generating corresponding model editing information according to the model editing instruction;

[0009] S3: Use the information sending module to send information: send the data information that needs to be synchronized after the model is edited to the server, so as to trigger the server to display the model editing information on the corresponding model display page, and the client sends an intermittent request to the server through the information sending module, and the server returns the data after receiving the request;

[0010] S4: The server uses the content audit module to perform content audit on the received information: uses the legitimacy verification module to verify the legitimacy of the writer and the correctness of the format of the written information on the model editing information sent to the server by each access terminal;

[0017] S11: Integrate the database design software client with the BIM software, so that the BIM software can directly interact with the database, write the database data into the BIM model in batches through program automation, and synchronize the modified information of the BIM software to the database. For the client that monitors and subscribes to database changes, the database has an information change broadcast mechanism. The database will broadcast the updated data to the client from time to time to achieve real-time data transmission.
