Semantic Gateway Ontology Mapping for Heterogeneous Device Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semantic gateway technologies face challenges in efficiently integrating and maintaining heterogeneous information systems due to the need for specific modeling according to different fields and services, leading to increased workload and difficulty in deploying and updating models, especially with the introduction of new equipment.
Innovation Solution
A method for a semantic gateway that involves inputting protocol data from diverse devices, performing protocol analysis and syntax induction to obtain protocol ontologies, followed by semantic queries and matching using a dictionary and model ontology library to generate a generic model, enabling mapping and information exchange among heterogeneous devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specific modeling is performed according to different fields and services, then the integration accuracy of heterogeneous information systems is improved, but the modeling workload and system complexity increase
Solution Approach 1:
The patent segments the modeling process into two distinct levels: a generic model that captures common patterns across all heterogeneous devices, and specific models for individual device types. This segmentation allows the system to achieve accurate integration through the generic model while reducing modeling workload by avoiding redundant specific modeling for each device.
Solution Approach 2:
The patent creates a universal generic model that can handle multiple types of heterogeneous devices across different fields and services. This generic model serves multiple functions by providing a common framework for information integration, thereby reducing the need for field-specific or service-specific modeling while maintaining integration accuracy.
2Adaptability or versatility
If a comprehensive model library is built to support various protocols, then the adaptability to different devices is improved, but the difficulty of maintaining and updating models increases
Solution Approach 1:
The patent merges the common characteristics of multiple device protocols into a single generic model. By combining shared features and abstractions, the system achieves broad device compatibility while simplifying model maintenance, as updates to the generic model automatically benefit all device types that conform to its structure.
3Measurement precision
If detailed protocol analysis is performed for each device, then the information extraction accuracy is improved, but the processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary protocol analysis during the model creation phase to establish the generic model structure. By conducting this analysis in advance and capturing common patterns, the system achieves accurate information extraction without repeating detailed protocol analysis for each device, thereby reducing processing time and computational resources during deployment.
