Detailed Description
The embodiment of the invention provides a method and a device for constructing a BIM full-period data model, and a computer readable storage medium, which are used for constructing a BIM full-period management data model for centralized management and effectively solving the problems of data fault and relationship integration in the BIM project implementation process.
In order that those skilled in the art will better understand the present invention, reference will now be made to the accompanying drawings in which embodiments of the invention are illustrated, it being apparent that the embodiments described are only some, but not all, of the embodiments of the invention. Based on the embodiments of the present invention, it should be understood that the present invention is within the scope of protection.
The graph database source starts Euler and graph theory, stores and queries data in a graph data structure, and has the advantage of quickly solving the problem of complex relationships. The graph database has three implementations in storage technology: protograms, triples, and relational-based databases. Native graphs generally refer to attribute graph models that have been accepted and supported by an increasing number of graph database vendors as graph database technology continues to evolve. Attribute graphs allow a set of variable attribute lists per node and edge, where an attribute is a value associated with a name, simplifying the graph structure. Multiple graphs allow multiple edges to exist between two nodes, meaning that two nodes can be connected multiple times by different edges, even though the two edges have the same tail, head, and label. Through the attribute graph model, the problem of data fault and relationship integration in the BIM project implementation process can be well solved.
Based on this, an embodiment of the present invention proposes a scheme for building a BIM full period data model based on an attribute map model, as shown in fig. 1, which is a schematic diagram of an embodiment of a method for building a BIM full period data model in an embodiment of the present invention, and may include:
101. Building attribute graph models of different stages are designed.
It will be appreciated that embodiments of the present invention are based on graph database technology, but are not limited to a particular graph database product. A more flexible attribute map is adopted in the expression of the building model; other business data models, in addition to the building model itself, constraints are expressed using attribute maps.
Building attribute graph model design: the method takes a component attribute map data model as a core, and designs building attribute maps and relation models of different layers. Based on the relation model, the analysis of the spatial association relation between the components can be provided, the situation of relying on a graphic platform is eliminated, and the calculation can be directly performed based on a graph database.
Optionally, the building attribute map model of the different stages includes: at least one building group attribute map model, each building group attribute map model comprising at least one individual building attribute map model, each individual building attribute map model comprising at least one area attribute map model, each area attribute map model comprising at least one component attribute map model. Or,
the building attribute graph model of the different stages comprises: at least one building group attribute map model, each building group attribute map model comprising at least one individual building attribute map model, each individual building attribute map model comprising at least one component attribute map model.
Optionally, if the at least one component property graph model includes at least two component property graph models, a spatial association relationship exists between each of the at least two component property graph models.
Optionally, each building group attribute map model, each individual building attribute map model, each area attribute map model, and each component attribute map model respectively include a corresponding label.
Optionally, the building attribute map models of the different stages include corresponding version number tags. I.e. the building attribute graph model of each stage has its own corresponding version number label.
It will be appreciated that the model design of the building attribute map will be described below from two perspectives. Fig. 2A is a schematic diagram of a hierarchical relationship of building attribute diagrams according to an embodiment of the present invention. In FIG. 2A, the building group attribute map model is shown on a model layer structure as a root node or dataset for the entire building attribute map model; the single building attribute graph model is used as a child node of the building group attribute graph model; the regional attribute graph model is taken as a child node of the single building attribute graph model, and the 'region' refers to the definition of space, such as a 'conference room', 'tea room', 'office area', and the like; the component attribute graph model can be used as a child node of the regional attribute graph model and can also be used as a child node of the single building attribute graph model, and the component attribute graph model is mainly dependent on the division condition of regional space.
Wherein, on the attribute map model expression, it is redefined from two aspects:
1. attribute definition
From the aspects of uncertainty and expansibility of data, the attribute is stored in a Key-Value pair form (namely Key-Value). The attributes of the building group attribute map model, the single building attribute map model and the regional attribute map model need to be defined according to actual service conditions; the attributes of the component attribute map model are determined, and component geometric parameters and non-geometric parameters defined by the design model are generally used as attribute descriptions.
2. Relationship definition
For building attribute graph models, the definition of the relationship is divided into two types: one is a subordinate relationship (i.e., parent-child node relationship), and the other is a spatial relationship.
The affiliation is used for describing the relationship among the building group attribute graph model, the single building attribute graph model, the regional attribute graph model and the component attribute graph model.
Spatial relationships, used to describe the spatial geometric relationships between components, can be subdivided into intersecting relationships and host parasitic relationships. The intersection relationship is used to describe the spatial geometry of two relatively independent components, while the host parasitic relationship is used to describe a relationship like "wall and door window", "floor and hole" or "shear wall and hole".
In addition, the component property graph model requires the addition of a tag (ID) property for association queries with external geometric model objects. The component attribute map provides geometric parameters, non-geometric parameters and relation information in design, which is sufficient for the development of related applications based on a building attribute map model; thus getting rid of the dependence on professional design tools or platforms and truly realizing the application based on the 'relational data'. For the requirement of geometric model presentation, a third party BIM lightweight technical platform can be docked, and BIM professional design tools can also be docked, and details are omitted here.
102. And acquiring business data models of different stages, wherein the business data models of different stages correspond to the building attribute graph models of different stages.
The construction device acquires business data models of different stages, wherein the business data models of different stages correspond to the building attribute graph models of different stages. It can be understood that after building attribute map models of different stages are designed, building attribute map models and relationship models can be obtained, and in particular, a service data model based on a component attribute map can be derived or uploaded into a map database through a special model design tool chain such as Revit, bentley.
Optionally, the service data model of the different stages includes: at least one building group business data model, each building group business data model comprising at least one individual business data model, each individual business data model comprising at least one area business data model, each area business data model comprising at least one component business data model; or,
the business data model of the different stages comprises: at least one building group business data model, each building group business data model comprising at least one individual business data model, each individual business data model comprising at least one component business data model.
Wherein the at least one building group attribute map model corresponds to the at least one building group business data model, the at least one individual building attribute map model corresponds to the at least one individual business data model, the at least one area attribute map model corresponds to the at least one area business data model, and the at least one component attribute map model corresponds to the at least one component business data model.
Optionally, parameters corresponding to the building attribute graph model in different stages and the business data model in different stages are stored in a key value pair mode.
Optionally, the building attribute map model of the different stages includes: designing a building attribute graph model in a stage, a building attribute graph model in a construction stage and a building attribute graph model in an operation and maintenance stage; the business data model of the different stages comprises: the method comprises the steps of designing a business data model of a stage, a business data model of a construction stage and a business data model of an operation and maintenance stage.
It will be appreciated that the Revit design software and the SDK provided by the same are taken as examples herein to assist in describing how to obtain the building attribute map and the relationship model. The description of how the graph database (including database connections and data reads and writes) is used is not repeated here. The graph database has two basic objects: nodes and relations. Different graph database techniques may differ in terms of terms, such as node objects sometimes being referred to as vertices, documents, and relationship objects sometimes being referred to as edges.
FIG. 2B is a schematic diagram of a building node relationship model according to an embodiment of the present invention. In the illustration of the view of figure 2B,representing node objects, representing relationship objects, representing association directions (unidirectional or bidirectional), generally supports the search of forward and backward (inner and outer) association nodes, so that bidirectional association relationships are not necessarily required to be established, and thus some data volume can be reduced. Wherein the virtual frame portion is used as a further refinement of the component property graph model of fig. 2A.
The nodes and the relations can be added with a plurality of labels according to actual needs, for example, a component model node represents a component model, a component label can be added, and if the type of the component is to be judged in actual calculation, the type (such as a column, a beam, a plate and the like) of the component or other custom labels can be added. The "belongings" and "instances" on the arrows in the above figures are label identifications of the relationship between two nodes.
It should be noted that, in order to avoid the occurrence of "super nodes" (a relationship is established between one node and a large number of nodes), component nodes are not directly associated with building nodes unless the number of component nodes is not large as expected.
Two aspects of attribute definition and relationship definition are described below, as follows:
1. attribute definition
The node and the relation can be added with the attribute, the patent model mainly takes the node attribute as a main part, and the Revit is taken as an illustrative node model attribute acquisition mode.
(1) Non-geometric parameters
The Element is a Revit basic Element type, and the component type (Element type) are inherited from the Element, so that the component and component type object related attribute can be obtained from the Element. Parameters provided by the Revit API.
The attribute object type is Parameter, where Parameter. Definition. Name defines the Parameter name, parameter. Definition. UnitType defines the Parameter unit. Parameter values of corresponding types are respectively obtained through RevitAPI parameter. Asdouble (), parameter. AsElementId (), parameter. AsInteger (), and parameter. AsString ().
The component and type names can be obtained directly through the element.
(2) Geometric parameters
The parameters of the component volume, area, length, etc. can be directly obtained (if any) from the parameter list, and other geometric parameters are calculated by the Element BoundingBoxXYZ, solid.
BoundgBoxXYZ is obtained through API element. Get_BoundgBox ().
The Solid is the geometric entity type of the Revit Element (Element) and can be obtained through the Geometry attribute of the Element.
2. Relationship definition
And judging the basic relationship of the Revit nodes.
(1) Component and component type
The component object element GetTypeId () method can obtain the ID (element Id) of the type, and the element document GetElement (element Id) method can obtain the specific component type object, so that the instantiation dependency relationship between the component and the component type can be established.
(2) Component and region
Taking elevation (floor) as an example for area judgment, an element. Level Id attribute defines the elevation Id associated with the component, and a corresponding elevation object Level can be obtained through the element. Document. GetElement (element Id), so that the association relationship between the component and the elevation can be determined, and the relationship between the component type associated with the component and the elevation can be directly determined from (1).
(3) Building and area
In the Revit, how many elevations of one project can be directly filtered out through an element filter Filter element collector, and the filtered elevations and building nodes are in accordance with the association relation, so that other judgment is not needed:
collector.OfClass(typeof(Level)).WhereElementIsNotElementType()；
(4) Component and component
In the relational model, there may be a spatial association between the members.
The spatial association of the components in Revit can be calculated mainly in two ways:
1. there is a direct correlation: for example, in the Revit, taking the relationship between wall and door and window as an example, the Host attribute of the door and window object records the ID of the wall component where the door and window is located, the component with the recorded related attribute can directly judge the relationship between the components, and the Host component ID can be obtained by the Host attribute value of the hole object (the hole object type in the Revit is open).
2. There is no direct correlation: whether there is an association is determined by the region information (boundingbox xyz) and the geometric entity (Solid) of the Revit member.
The specific calculation method will be different in actual service requirements, and will not be described here again.
(5) Other relationships
The association relationship may be determined according to the actual item setting and the geographical information.
103. And constructing according to the building attribute graph models of the different stages and the business data models of the different stages to obtain a BIM full-period data model.
Building a BIM full-period data model: an expansion method and specification of a design data model provide a foundation for business application expansion and data access. With the continuous increase of data in the BIM full period, the characteristics of the attribute map are utilized, and the performance of the BIM full period is guaranteed.
The building process of the BIM full-period data model refers to the design process of the business data model related to each stage of the project and the process of building a relation between the business data model and the building attribute graph model or the business data model. FIG. 2C is a block diagram of a BIM full cycle data model in accordance with an embodiment of the invention.
In the present patent, a BIM project is used as a graph database. As shown in the BIM full-period data model structure diagram of FIG. 2C, the building attribute graph model and the related business data model in each stage are used as primary nodes, and each model uses the node as a father node to carry out data construction.
In general, the building of the BIM full period data model has three main processes:
(1) A new data model root node, the node label at least needs to define the following two types of labels for inquiring:
Stage class labels: design, construction, operation and maintenance, etc.;
building type label: building;
version number tag: such as V1.0, V1.1, etc.
(2) Business class data model attribute map definition
Structural specification: the attributes store a structure key pair form.
Relationship specification: the business model internal relationships are not limited, but follow the consistency principles.
(3) Construction of relationship between business data models
Relationship specification: relationships between models must define the properties of the relationship model as access rights control for the associated data. In particular, when associating with building interior component models, a label defining a relationship is required for distinguishing the relationship of the building component model from different business models for data visibility range control.
Step 101 is performed around a component attribute map of a building and a relationship model thereof; the design of the architectural attribute map model and the relationship model are important components of the present embodiment.
FIG. 2C is a diagram of a BIM full cycle data model structure, which is divided into two parts: the left part represents a business data model, and the right part represents an attribute graph model of a building; the model structure is divided into a plurality of main stages of design, construction, operation and maintenance and the like according to the characteristics of the building project; in the BIM full period data model, these three main phases are included, but are not limited to. Therefore, step 101 only illustrates the building attribute diagram and its relationship model, and the method is applicable to building design models at different stages; for the business data model, a method and specification for expanding the BIM full period data model is described in step 103. Step 102 mainly describes a construction method of a building attribute map data model, and because of the existence of numerous professional model design tools, the present patent uses mainstream Revit products as an example to describe technical details.
In the embodiment of the invention, building attribute graph models at different stages are designed; acquiring business data models of different stages, wherein the business data models of different stages correspond to the building attribute graph models of different stages; and constructing according to the building attribute graph models of the different stages and the business data models of the different stages to obtain a BIM full-period data model. And constructing a BIM full-period management data model according to the building attribute graph models at different stages and the business data models at different stages, performing centralized management, and effectively solving the problem of data fault and relationship integration in the BIM project implementation process. A data model supporting BIM full period management is designed to serve as centralized management, and is also the basis for successful implementation of BIM projects.
As shown in fig. 3, which is a schematic diagram of an embodiment of a construction apparatus according to an embodiment of the present invention, may include:
a design module 301, configured to design building attribute map models at different stages;
the acquiring module 302 is configured to acquire service data models of different stages, where the service data models of different stages correspond to the building attribute map models of different stages;
