Description

Engineering project data multidimensional multiplexing method based on BIM and component identity label

Technical Field

The invention relates to the field of engineering project data management, in particular to a BIM and member identity tag-based engineering project data multidimensional multiplexing method.

Background

More and more projects are managed by using a Building Information Modeling (BIM) technology in the construction process, a general BIM model and data management mode is that data is added as component parameters and stored in a model, and after the project BIM management platform uploads the model to the platform, model data and model components are extracted by using an element ID (RevitID for short) of Revit software as a data tag.

However, the following problems exist when BIM management is performed in urban Information model (CIM) level engineering projects such as rail transit:

1. the data tag is meaningless: RevitID is only a serial number automatically generated by software, lacks common information such as location and category information, and therefore cannot be used directly for data screening. 2. Item data scatter cannot integrate: data is stored in each model in a scattered mode, the RevitID is used as a data tag to only ensure uniqueness in a single model, but if the number of models is huge, the RevitID is used as a data tag to store data in a centralized mode, RevitID repetition occurs on different components in different models, and management data confusion is caused. 3. The floor management cost is high: due to the functional limitation of Revit software, most of the entry processes need manual entry item by item, and the workload is large. 4. The multi-platform data cannot be shared: the number of the participating BIM management platforms is large, unique data label correspondence is lacked, the platforms operate independently, data among the platforms cannot be communicated, meanwhile, service contents need to be repeatedly reported on different platforms, and project management cost can be increased. 5. Difficulty in obtaining basic information of the component: the position information can only be obtained by manually viewing the model, and the obtained result may be unreliable due to the uneven quality of the model. 6. Difficulty in inheritance of management data: the model can be iteratively updated for many times in the project implementation process, the components in the model can be replaced, added, deleted and adjusted, and the data contained in the replaced components cannot be automatically inherited to the new component model and can only be manually re-entered.

Disclosure of Invention

In view of the above, an object of the present invention is to overcome the defects in the prior art, and provide a method for multidimensional multiplexing of project data based on BIM and component identity tags, which can solve the problems of more information, difficult management, difficult transmission, difficult coordination, and difficult BIM application landing in a project, so that multidimensional multiplexing of project data across platforms, stages, and units is achieved.

The invention discloses a BIM and member identity label-based engineering project data multidimensional multiplexing method, which comprises the following steps:

s1, determining classification codes and position code rules of components according to a set coding standard and constructing a BIM (building information modeling) model of a project;

s2, generating a component identity label (CIT) of each component in the BIM according to the classification code and the position code rule of the component;

s3, mapping all information of the BIM to generate a BIM database associated with the CIT;

s4, extracting CIT in the BIM or BIM database to form an independent CIT library;

s5, associating the CIT of the component in the CIT library with corresponding component management data in the service database;

and S6, calling a CIT library according to the service requirement, screening a CIT set of the required component from the CIT library, and managing the project data by taking the CIT set as a basis.

Further, the component identity label CIT comprises a classification code, a position code and a serial number; the classification code includes category information of the component, the position code includes position information of the component, and the serial number is a set of numbers used to distinguish the same category from the position component.

Further, the CIT in the BIM model database is associated with technical indexes; the technical index comprises key technical index information of the component.

Further, the business database comprises a building phase BIM management database, an operation and maintenance phase BIM management database and a project supervision BIM management database.

Further, managing the engineering project data specifically includes: operating corresponding management information in a BIM management database, inquiring attribute information corresponding to CIT in a BIM model database and positioning corresponding components in the BIM model.

Further, the method further includes iteratively updating the BIM model, specifically including:

and backing up the BIM before updating, and updating the components and technical indexes in the BIM.

Further, updating the components in the BIM model, including replacing, deleting, adding, and adjusting the components in the BIM model;

for the operation of the replacement component, assigning the CIT of the replaced component to the new replacement component;

for the operation of deleting the component, the CIT of the deleted component is reserved and is not used for other purposes;

for the operation of the newly added component, a new CIT is given to the newly added component according to the CIT rule in the original BIM;

for the operation of adjusting the component, no processing is required for the CIT of the component.

Further, the updated BIM model is set to step S3, and steps S3-S6 are performed.

The invention has the beneficial effects that: the invention discloses a BIM and member identity label-based engineering project data multidimensional multiplexing method, which has the following beneficial effects:

1. the data tag meaning is given, so that the data tag meaning can be directly used for project management: because the CIT contains component type and position information, the requirement of screening most business data can be met. In the process of business application, the components can be screened according to the category information and the position information contained in the CIT only by calculating and screening the CIT database, and the applications of branch management, engineering quantity list extraction and the like are realized.

2. The data are stored in a centralized way, so that the management and the use are convenient: the CIT is able to precisely define the component and ensure uniqueness of the CIT with the corresponding component at the project level and even within the CIM level. And by means of the uniqueness of the CIT, mapping all the BIM models to generate a BIM model database associated with the CIT, and associating the data in the BIM management database with the CIT to realize the centralized management of all the BIM data. Meanwhile, the CIT and the geometric body of the component have a one-to-one corresponding relation, so that the component model can be positioned, checked, screened and the like by means of the CIT. Finally, a management system which takes the BIM database as a core and uses CIT as a medium and separates the geometric form of the model from the BIM data is formed.

3. Data storage position has been optimized, information management work load has been reduced: because the BIM only needs to input CIT and technical index information, the workload of unified modeling standard, model establishment and result inspection is greatly reduced. The project platform has high customizable attributes, can develop a rapid entry means of management information according to project requirements, and can reduce the workload of management information entry, thereby solving the problem of high floor management cost.

4. The cross-platform, cross-unit and cross-stage multi-dimensional digital management is realized: for different management platforms, data intercommunication among the platforms can be realized only by ensuring the consistency of CIT; the information data of the same component of different platforms can be merged by means of CIT, and the information or model entity of the corresponding component can be directly called from other platforms by means of CIT, so that one-time input and full-project use are realized, and the workload of information input can be reduced. Meanwhile, for the iteration of the project model, after the model component is replaced and updated, the management information of the original component can be inherited to the new component only by ensuring that the updated component CIT is consistent with the original component CIT.

5. The database is directly operated and managed, and the compatibility problem caused by different formats of different modeling software generation models is shielded: the BIM model database and the BIM management database are directly managed by means of CIT, so that the method is quicker and more convenient, the BIM model is only used for positioning and displaying related contents, and the compatibility problem caused by different modeling software generation model formats can be effectively shielded.
