Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building management systems (BMS) lack a standardized approach to integrating and managing various building systems, leading to inefficiencies and challenges in user interaction and system control.
Innovation Solution
A BMS that utilizes a semantic model to map BMS objects to an ontology data model, enabling semantic information to be associated with these objects, and allowing for standardized classification and updating of a semantic site model to adjust parameters and control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a BMS integrates multiple building systems without standardization, then system functionality is enhanced, but device complexity and difficulty of management increase
Solution Approach 1:
The patent applies universality by implementing a standardized semantic model that serves as a common framework for integrating diverse building systems (HVAC, lighting, security, etc.). The semantic model provides universal object definitions, classifications, and relationships that enable multiple building systems to be managed through a unified interface, reducing management complexity while maintaining integration capability.
Solution Approach 2:
The patent changes the fundamental parameters of system representation by introducing standardized semantic classifications and ontological frameworks. Instead of managing systems through proprietary protocols and formats, the system transforms data into standardized semantic parameters, enabling consistent interpretation and management across different building systems.
2Ease of operation
If BMS objects are mapped to ontology data models with semantic information, then ease of operation and user interaction improve, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary layer in the form of a semantic model that mediates between the complex underlying building systems and the user interface. This semantic layer translates complex system data into standardized, easily interpretable semantic representations, allowing users to interact with building systems through simple queries and operations without needing to understand the underlying complexity.
Solution Approach 2:
The patent creates a semantic copy or representation of building systems that simplifies interaction. Instead of users directly interacting with complex system protocols and data structures, the semantic model provides a simplified conceptual copy that captures essential object properties and relationships in an easily understandable format.
3Measurement precision
If semantic information is obtained and classified for BMS objects, then measurement precision and data standardization improve, but loss of time in processing increases
Solution Approach 1:
The patent applies preliminary action by pre-defining semantic classifications, object types, and relationships in the semantic model before actual data processing occurs. This pre-established framework allows for rapid classification and mapping of BMS objects without time-consuming analysis during processing, as the semantic structure is already in place to guide data interpretation.

AI summary
A building management system (BMS) includes one or more memory devices having instructions stored thereon. When executed by one or more processors, the instructions cause the processors to perform operations including ingesting semantic information associated with a plurality of BMS objects, classifying the plurality of BMS objects into a plurality of predetermined classifications that pertain to the plurality of BMS objects using the semantic information, updating a semantic site model for a building site by including at least one of the semantic information associated with the plurality of BMS objects or the plurality of predetermined classifications that pertain to the plurality of BMS objects, and adjusting a plurality of parameters associated with the plurality of BMS objects using the semantic site model.
