BAS-BIM Mapping for 3D Building Equipment Interfaces

The patent introduces a BIM model as an intermediary between the BAS data and the graphical display. The BIM model serves as a mediator that provides high-quality 3D graphical representations of building equipment, while the BAS-BIM integrator acts as an intermediary component to map and connect BAS points to corresponding BIM objects. This resolves the contradiction by obtaining high-quality graphics without requiring the BAS to generate its own low-quality graphics internally.

The patent uses the BIM model as a copy or representation of the actual building equipment. Instead of generating original graphics within the BAS, the system copies the detailed 3D models from the BIM, which were created during the design phase. This allows the BAS to display high-quality graphical representations without having to create them from scratch, resolving the graphics quality issue while maintaining system functionality.

The patent segments the integration process into distinct functional components: a BAS-BIM integrator that handles data mapping, a BAS tree generator that organizes BAS points hierarchically, a BIM tree generator that structures BIM objects, and a mapping interface that connects them. This segmentation makes the complex integration task manageable by breaking it down into smaller, more manageable parts with clear responsibilities.

The patent introduces several intermediary components to facilitate the integration between BAS and BIM. The BAS-BIM integrator serves as a mediator that establishes mappings between BAS points and BIM objects. The mapping interface acts as an intermediary layer that allows users to define relationships between the two systems. These intermediaries simplify the integration process by providing standardized interfaces and abstraction layers.

The patent applies preliminary action by creating detailed 3D BIM models during the design and construction phase, before the BAS is implemented. These pre-created models contain all the necessary graphical information about building equipment. When the BAS is deployed, it can directly utilize these pre-existing high-quality models without requiring time-consuming manual graphics creation, thus improving both productivity and graphics quality simultaneously.

Instead of manually creating graphics in the BAS interface, the system copies pre-existing high-quality 3D models from the BIM. This copying approach eliminates the time-consuming manual graphics creation process while maintaining high graphics quality. The BIM models serve as reusable assets that can be directly instantiated in the BAS interface through the integration layer.
