Description

Technical Field

[0001] This invention relates to the field of building digital twin technology, and more specifically, to a method and terminal device for calculating building spatial relationships. Background Technology

[0002] Digital twins refer to the simulation process that fully utilizes data such as physical models, sensor updates, and operational history to integrate multiple disciplines, multiple physical quantities, multiple scales, and multiple probabilities, and completes mapping in virtual space to reflect the entire life cycle of the corresponding physical equipment.

[0003] Specifically, building digital twin refers to the process in engineering construction where, in order to more intuitively and clearly display the spatial layout and structure of a target building, construction personnel typically build a building information model that reflects the physical and functional characteristics of the target building after its completion. This building information model serves as the digital twin model of the target building, allowing for convenient management of the target building through the digital twin model.

[0004] The current method of delivering architectural spatial relationships involves on-site surveys by delivery personnel, who record the relationships between spaces in a two-dimensional manner. However, everyone's understanding of the relationships between architectural spaces differs, and the delivered content may deviate from objective reality. Furthermore, when the building site is large and there are many examples of architectural spaces, delivering the relationships by personnel is time-consuming. Moreover, as the building enters the operation and maintenance phase, spatial modifications frequently occur, requiring personnel to be on-site each time to record changes and update the architectural spatial relationships. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The technical problem that this invention aims to solve is that the existing delivery steps for architectural spatial relationships are characterized by low automation, long processing times, and a lack of unified delivery standards.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] In a first aspect, the present invention provides a method for calculating architectural spatial relationships, comprising the following steps:

[0010] The basic model of the building structure is created by using architectural design software and the attribute information of each building structure is entered to form an architectural model. The architectural model has a two-dimensional architectural space with the same number of floors as the building structure.

[0011] Using rooms as units, the area used for living and production activities in the two-dimensional architectural space is divided into property zones, wherein the property zones have a closed first spatial outline;

[0012] Calculate the property zoning relationship based on the installation coordinates of various structural equipment in the actual building;

[0013] The fire protection deployment area in the two-dimensional building space is divided into fire compartments, and the fire compartments have a second spatial outline.

[0014] The parking area in the two-dimensional building space is divided into parking zones, and the parking zones have a third spatial outline.

[0015] Based on the relationship between the first spatial outline, the second spatial outline, and the third spatial outline, calculate the spatial relationship between property zones, fire zones, and parking zones.

[0016] In one embodiment, the spatial relationships include: property zones separated by doors, property zones connected to each other, property zones longitudinally adjacent to each other, fire zones containing property zones, fire zones connected to each other, parking zones containing property zones, and parking zones connected to each other.

[0017] In one embodiment, the calculation steps for determining whether there is a door separating the property zones are as follows: based on the attribute information of each building structure entered in the building model, the outline of the door structure in the building structure is identified. The door structure includes: ordinary door, fire door, air-raid shelter door, elevator door, and fireproof roller shutter. In the same two-dimensional building space, if two adjacent first space outlines have overlapping first boundaries, and the first boundary is included in the outline of the door structure, then it is determined that there is a door separating the property zones. Wherein, when the door structure is an ordinary door, it is also required that the ordinary door is not a doorway.

[0018] In one embodiment, the calculation steps for the connectivity between property zones are as follows: based on the attribute information of each building structure entered in the building model, the outline of a first specific instance in the building structure is identified. The first specific instance includes: walls, ordinary doors of type other than door openings, fire doors, air-raid shelter doors, curtain wall panels, and curtain wall keels. Within the same two-dimensional building space: in the first case, if two adjacent first space outlines have overlapping first boundaries, and the first boundaries are contained within the outline of the first specific instance, then the property zones are considered not to be connected; otherwise, the property zones are considered to be connected. If the first boundary only intersects with a second specific instance, and the length of each line segment in the non-intersecting outline is less than 100mm, then the property zones are considered not to be connected. The second specific instance includes: walls, curtain wall panels, and curtain wall keels. In the second case, if two adjacent first space outlines have overlapping first boundaries, and the first boundaries are contained within or intersect with the outline of the ordinary doors of type door openings, then the property zones are considered to be connected.

[0019] The union of the first case and the second case is taken as the final calculation result.

[0020] In one embodiment, the calculation steps for the vertical adjacency of property zones are as follows: Identify the property zones in the two-dimensional architectural spaces of two adjacent standard floors; vertically project the property zone located on the upper floor's two-dimensional architectural space onto the lower floor's two-dimensional architectural space (not a mezzanine floor); if the projection of the upper floor's property zone overlaps with the lower floor's property zone, then the property zones are determined to be vertically adjacent; during the calculation process: if the lower floor is a mezzanine floor, the calculation proceeds downwards sequentially until the next floor is a non-mezzanine floor, and it is necessary to determine whether the upper floor's two-dimensional architectural space and the lower floor's two-dimensional architectural space have spatial occlusion; if spatial occlusion exists, the vertical adjacency relationship is not calculated; if no spatial occlusion exists, the vertical adjacency relationship can be calculated. 。

[0021] In one embodiment, the calculation steps for the fire compartment including the property compartment are as follows: within the same two-dimensional building space, the positions of the first spatial outline and the second spatial outline are identified respectively; if the second spatial outline includes the first spatial outline, it is determined that the fire compartment includes the property compartment; the number of areas of the first spatial outline included in the second spatial outline is counted, and the number of areas is the number of property compartments included in the fire compartment.

[0022] In one embodiment, the calculation steps for the connectivity between fire compartments are as follows: based on the attribute information of each building structure entered in the building model, the outline of a first specific instance in the building structure is identified. The first specific instance includes: walls, ordinary doors of type other than door openings, fire doors, air-raid shelter doors, curtain wall panels, and curtain wall joists. Within the same two-dimensional building space: in the first case, if two adjacent second space outlines have overlapping second boundaries, and the second boundaries are contained within the outline of the first specific instance, then the fire compartments are considered not to be connected; otherwise, the fire compartments are considered to be connected. If the second boundary only intersects with the second specific instance, and the length of each line segment in the non-intersecting outline is less than 100mm, then the fire compartments are considered not to be connected. The second specific instance includes: walls, curtain wall panels, and curtain wall joists. In the second case, if two adjacent second space outlines have overlapping second boundaries, and the second boundaries are contained within or intersect with the outline of the ordinary door of type door opening, then the fire compartments are considered to be connected.

[0023] The union of the first case and the second case is taken as the final calculation result.

[0024] In one embodiment, the calculation steps for the parking zone including the property zone are as follows:

[0025] Within the same two-dimensional building space, the positions of the first spatial outline and the third spatial outline are identified respectively. If the third spatial outline contains the first spatial outline, it is determined that the parking zone includes the property zone.

[0026] The number of areas within the first spatial contour contained in the third spatial contour is counted, where the number of areas is the number of property zones contained in the parking zone.

[0027] In one embodiment, the calculation steps for the connectivity between parking zones are as follows: based on the attribute information of each building structure entered in the building model, the outline of a first specific instance in the building structure is identified. The first specific instance includes: walls, ordinary doors of type other than door openings, fire doors, air-raid shelter doors, curtain wall panels, and curtain wall keels. Within the same two-dimensional building space: in the first case, if two adjacent third space outlines have overlapping third boundaries, and the third boundaries are contained within the outline of the first specific instance, then the parking zones are considered not to be connected; otherwise, the parking zones are considered to be connected. If the third boundary only intersects with a second specific instance, and the length of each line segment in the non-intersecting outline is less than 100mm, then the parking zones are considered not to be connected. The second specific instance includes: walls, curtain wall panels, and curtain wall keels. In the second case, if two adjacent third space outlines have overlapping third boundaries, and the third boundaries are contained within or intersect with the outline of the ordinary door of type door opening, then the parking zones are considered to be connected.

[0028] The union of the first case and the second case is taken as the final calculation result.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this invention will be described in more detail below with reference to specific embodiments:

[0043] like Figure 1 As shown in the figure, this invention provides a method for calculating architectural spatial relationships, including the following steps:

[0044] S1. The basic modeling of the building structure is performed using architectural design software, and the attribute information of each building structure is entered to form a building model. The building model has a two-dimensional architectural space with the same number of floors as the building structure. Specifically, the architectural design software can be Revit. The building structure includes, but is not limited to: ordinary doors, fire doors, air-raid shelter doors, curtain wall panels, curtain wall framing, windows, columns, walls, etc.

[0045] S2. Taking rooms as units, the areas used for living and production activities in a two-dimensional architectural space are divided into property zones, where each property zone has a closed first spatial outline.

[0046] S3. Calculate the property zoning relationship based on the installation coordinates of each civil engineering structural equipment in the actual building; specifically, based on the property zoning outline in the building model and the two-dimensional coordinates of the placement of the building structural equipment, the property zoning relationship of each civil engineering structural equipment can be calculated.

[0047] S4. Divide the fire protection deployment area in the two-dimensional building space into fire compartments, and the fire compartments have a second spatial outline.

[0048] S5. Divide the parking area in the two-dimensional building space into parking zones, and each parking zone has a third spatial outline.

[0049] S6. Based on the relationship between the first spatial outline, the second spatial outline, and the third spatial outline, calculate the spatial relationship between the property zone, the fire zone, and the parking zone.

[0050] In one embodiment, the spatial relationships include: property zones separated by doors, property zones connected to each other, property zones longitudinally adjacent to each other, fire zones containing property zones, fire zones connected to each other, parking zones containing property zones, and parking zones connected to each other.

[0051] In one embodiment, the calculation steps for determining whether there is a door separating property zones are as follows: Based on the attribute information of each building structure entered into the building model, the outline of the door structure in the building structure is identified. The door structure includes: ordinary door, fire door, air defense door, elevator door, and fireproof roller shutter; In the same two-dimensional building space, if two adjacent first space outlines have overlapping first boundaries, and the first boundary is contained within the outline of the door structure, then it is determined that there is a door separating property zones. Wherein, when the door structure is an ordinary door, it is also required that the ordinary door is not a doorway.

[0052] In one embodiment, the calculation steps for connectivity between property zones are as follows:

[0053] Based on the attribute information of each building structure entered into the building model, the outline of the first specific instance 10 in the building structure is identified. The first specific instance includes: walls, ordinary doors of type other than door openings, fire doors, air-raid shelter doors, curtain wall panels, and curtain wall keels. In the same two-dimensional building space: in the first case, if two adjacent first space outlines have overlapping first boundaries, and the first boundary is contained within the outline of the first specific instance, then the property zones are considered not connected; otherwise, the property zones are considered connected. If the first boundary only intersects with the second specific instance, and the length of each line segment in the non-intersecting outline is less than 100mm, then the property zones are considered not connected. The second specific instance includes: walls, curtain wall panels, and curtain wall keels. In the second case, if two adjacent first space outlines have overlapping first boundaries, and the first boundary is contained within or intersects with the outline of an ordinary door of type door opening, then the property zones are considered connected.

[0054] The union of the first and second cases is taken as the final calculation result.

[0055] like Figure 2 As shown, specifically, if the first overlapping boundaries in the first spatial outlines of two adjacent property zones are completely contained within the spatial outline of a first specific instance 10 under a specified equipment class (such as a wall, a regular door of type other than a doorway, a fire door, a civil defense door, a curtain wall panel, or a curtain wall keel), then the two property zones are considered disconnected; otherwise, they are considered connected. If the first overlapping boundaries in the first spatial outlines of two adjacent property zones intersect with (or are completely contained within) the spatial outline of a regular door of type doorway, then the two property zones are considered connected. Figure 3 As shown, it should be noted that the following are special cases: if the first boundary area only contains the outline of the wall, curtain wall panel and curtain wall keel, and the length of the outline of the non-overlapping part 20 is ≤100mm, in this case, the two property zones are not connected.

[0056] In one embodiment, the calculation steps for the vertical adjacency of property zones are as follows:

[0057] Identify property zones in the two-dimensional architectural spaces of two adjacent standard floors; vertically project the property zone in the two-dimensional architectural space of the upper floor onto the two-dimensional architectural space of the lower floor (not a mezzanine floor). If the projection of the property zone on the upper floor overlaps with that on the lower floor, the property zones are determined to be longitudinally adjacent. During the calculation process: if the lower floor is a mezzanine floor, the calculation should proceed downwards until the lower floor is a non-mezzanine floor. It is also necessary to determine whether there is spatial occlusion between the two-dimensional architectural spaces of the upper floor and the two-dimensional architectural spaces of the lower floor. If there is spatial occlusion, the longitudinal adjacency relationship is not calculated; if there is no spatial occlusion, the longitudinal adjacency relationship can be calculated.

[0058] Specifically, such as Figure 4 In the illustrated embodiment: F1, F2, and F3 are standard floors, and F1M is the mezzanine floor between F1 and F2. If there is no obstruction between the first space 1 and the second space 2, the vertical adjacency relationship between property zones can be calculated. If there is a fourth space 4 obstructing the third space 3 and the fifth space 5, the vertical adjacency relationship between property zones is not calculated. Spatial obstruction is indicated by calculating whether the outline of the intermediate floor intersects the outlines of the two standard floors above and below. If there is an intersection, it is considered spatial obstruction.

[0059] In one embodiment, the calculation steps for fire compartmentation including property compartmentation are as follows:

[0060] Within the same two-dimensional building space, the positions of the first spatial outline and the second spatial outline are identified respectively. If the second spatial outline contains the first spatial outline, it is determined that the fire compartment includes a property zone. The number of areas of the first spatial outline contained within the second spatial outline is counted, and the number of areas is the number of property zones included in the fire compartment. When dividing a fire compartment, it must contain N complete property zones; that is, a property zone cannot belong to multiple fire compartments. The number of property zones included in a fire compartment can be calculated using the fire compartment outline division method.

[0061] In one embodiment, the calculation steps for connectivity between fire compartments are as follows:

[0062] Based on the attribute information of each building structure entered into the building model, the outline of the first specific instance in the building structure is identified. The first specific instance includes: walls, ordinary doors of type other than door openings, fire doors, air-raid shelter doors, curtain wall panels, and curtain wall framing. Within the same two-dimensional building space: In the first case, if two adjacent second space outlines have overlapping second boundaries, and the second boundaries are contained within the outline of the first specific instance, then the fire compartments are considered not connected; otherwise, the fire compartments are considered connected. If the second boundary only intersects with the second specific instance, and the length of each line segment in the non-intersecting outline is less than 100mm, then the fire compartments are considered not connected. The second specific instance includes: walls, curtain wall panels, and curtain wall framing. In the second case, if two adjacent second space outlines have overlapping second boundaries, and the second boundaries are contained within or intersect with the outline of an ordinary door of type door opening, then the fire compartments are considered connected.

[0063] The union of the first and second cases is taken as the final calculation result.

[0064] In one embodiment, the calculation steps for parking zones including property zones are as follows:

[0065] Within the same two-dimensional building space, the positions of the first and third spatial outlines are identified respectively. If the third spatial outline contains the first spatial outline, it is determined that the fire compartment includes a property compartment. The number of areas of the first spatial outline contained within the third spatial outline is counted, and the number of areas is the number of property compartments contained in the parking compartment. When dividing parking compartments, it must contain N complete property compartments, that is, one property compartment cannot belong to multiple parking compartments. When dividing parking compartment outlines, the number of property compartments contained in the parking compartment can be calculated.

[0066] In one embodiment, the calculation steps for connectivity between parking zones are as follows:

[0067] Based on the attribute information of each building structure entered into the building model, the outline of the first specific instance in the building structure is identified. The first specific instance includes: walls, ordinary doors of type other than door openings, fire doors, air-raid shelter doors, curtain wall panels, and curtain wall keels. In the same two-dimensional building space: in the first case, if two adjacent second space outlines have overlapping second boundaries, and the second boundaries are contained within the outline of the first specific instance, then the parking zones are considered not connected; otherwise, the parking zones are considered connected. If the second boundary only intersects with the second specific instance, and the length of each line segment in the non-intersecting outline is less than 100mm, then the parking zones are considered not connected. The second specific instance includes: walls, curtain wall panels, and curtain wall keels. In the second case, if two adjacent second space outlines have overlapping second boundaries, and the second boundaries are contained within or intersect with the outline of an ordinary door of type door opening, then the parking zones are considered connected.

[0068] The union of the first and second cases is taken as the final calculation result.

When the processor executes the computer program, it implements a method for calculating architectural spatial relationships according to any of the above-mentioned technical solutions.
