As a preferred embodiment of the present invention, the method further comprises,
and taking the BIM component database and the attribute value database as BIM databases, interacting the data of the BIM databases with the data of any other BIM application platform in a bidirectional synchronous mode, and storing and reading the data of the BIM databases in a distributed storage and distributed access mode.
As a preferred embodiment of the present invention, the step 110 specifically includes the following,
the BIM component specifically comprises any one of a wall, a beam, a plate, a door, a window, an equipment part and a pipeline accessory, the unique ID adopts a mode of a global unique identifier GUID to ensure the uniqueness, and if the created BIM component is deleted or replaced in the process, the BIM component is correspondingly marked without deleting and replacing the existing process data before the BIM component is replaced.
As a preferred embodiment of the present invention, the step 120 specifically includes the following,

As a preferred embodiment of the present invention, the step 130 specifically includes the following,
and storing the process change data generated by the attribute values of the attributes along with the progress of the process into an attribute value database in real time, recording the change ID, the change person, the change time, the change reason and the model change value of the attributes, and pointing to the previous attribute value change record of the attributes to form a data chain.
Combining the above preferred schemes, the specific implementation mode of the method is as follows:
in the first step, a BIM component such as a wall, a beam, a plate, a door, a window, an equipment part, a pipeline accessory and the like is created on a BIM platform, and a unique ID is generated and used as a code number of the whole life cycle of the BIM component, and is stored in a BIM component database. The uniqueness ID adopts a Global Unique Identifier (GUID) mode to ensure uniqueness. BIM components are flagged as being deleted or replaced in the process, but process data that existed prior to deletion and replacement is not deleted.
Secondly, defining basic attribute sets including names, buildings, floors, component types, creating time, creators and the like according to the spatial positions, component types and the like of the BIM components and storing initial values of the basic attribute sets into an attribute value database, defining model attribute sets including spatial positioning, appearance shapes, constituent materials, weights and the like according to model characteristics and storing the initial values into the attribute value database, and defining attribute sets including planning, surveying, designing, bidding, construction cost, operation and maintenance and the like according to engineering management requirements and storing the initial values into the attribute value database. The initial value can be null, and other attributes can be defined and stored according to the step at any time according to needs. Attributes may also be pruned as needed, but simply marked as pruned and not really their stored process data.

The attribute value may be a model change value such as a shape change or a position change, or a change value such as a work volume, a construction progress, or a maintenance record. The change of the attribute value adopts a new record adding mode instead of covering the existing record, and a data change auditing process is added according to the requirement, so that the safety, reliability and accuracy of the data are fully ensured.
And fourthly, associating data sources of all reports of the process to the BIM components according to engineering management requirements, wherein if the construction progress can be associated with a plurality of BIM components, the planned starting time and the planned finishing time of the BIM components can be freely set, but the actual starting time, the actual finishing time and the instant progress of the BIM components can be obtained from the attribute values of the BIM components.

The BIM database uses distributed storage and distributed access to realize data application service with high availability, high performance, high expansion, high stability and high safety.
And sixthly, the engineering project data is required to be handed over to the next stage for use after the stage is completed, and the database can be synchronized immediately, so that the data flow is more convenient and fast.

firstly, a data carrier with the finest granularity is adopted, the current method of using the integral model version is changed, the data carrier is thinned to a single component of the BIM model with the smallest granularity, the unique ID of the BIM component is abstracted, and the names, the three-dimensional appearance shapes, all other process information and the like of the component are used as attributes to be hung on the abstracted BIM component.
And secondly, a storage mode based on a database is used, a mode that the current BIM model data is stored by using a document is changed, each BIM component is stored as a record of a component data table in the database, each attribute of the BIM component also uses a unique ID and is stored in an attribute data table in the database, the definition of the attribute can form a mode of an attribute set, process information such as planning, exploration, design, bid and bid, construction cost, operation and maintenance of the component forms the attribute set, and all information of the full life cycle of the BIM component is comprehensively recorded.
And thirdly, recording all historical change processes of the data, recording all attribute value changes of each attribute of each BIM component from the beginning of creation, storing the attribute value changes into an attribute value data table in a database, and fully recording the full life cycle data changes of each attribute of the BIM component.
And fourthly, all data sources of reports and files in the engineering construction process are related to the components and the attributes of the components, and the change process of the components and the attributes of the components is directly reflected on the report results.
And fifthly, organizing BIM components by defining virtual nodes to form a multilayer structure, for example, by defining three hierarchical structures of buildings, floors, specialties and the like, all the components of the buildings can be gathered into a directory tree, so that the data structure is enhanced, and the data access speed is increased.
And sixthly, a distributed storage mode is used, the data volume of the engineering project in the whole life cycle is very large, if the traditional storage mode is used, the data application requirements can not be met, and the data application service with high availability, high performance, high expansion, high stability and high safety is realized by using the distributed storage mode.

the BIM component creating module is used for creating the BIM component on the BIM platform, generating a unique ID as a code number of the full life cycle of the BIM component, and storing the BIM component into a BIM component database;
the attribute definition module is used for defining the attribute value of the BIM component and setting the initial attribute value as attribute data according to the component type and the engineering management requirement of the BIM component, wherein the attribute value comprises a basic attribute set, a model attribute set and the attribute set of planning, investigation, design, bid, construction cost and operation and maintenance data required by the engineering management, and the initial attribute value of the attribute value is stored in an attribute value database;
the data updating module is used for monitoring the change data of each attribute value of the BIM component in the engineering advancing process in real time, linking the change data to the previous change data record and storing the previous change data record to the attribute value database to form a data link;
and the data reading module is used for acquiring various reports and files generated in the engineering advancing process, associating data sources of the reports and the files to the BIM component, and reading required attribute data from the BIM component.
