Virtual Sensor Metadata Consistency Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack a specific method for generating metadata for virtual sensors that is consistent with the metadata from real sensors, leading to potential inconsistencies in sensing data.
Innovation Solution
A data generation apparatus and method that includes an obtaining unit for real sensor metadata, a reception unit for user-input metadata, a determination unit for consistency checks, and a generation unit to produce final metadata consistent with real sensor metadata, ensuring consistency before metadata generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metadata about virtual sensor is generated to reflect metadata about real sensors, then consistency between metadata is improved, but no specific method exists for generating such metadata
Solution Approach 1:
The system performs preliminary actions by obtaining metadata from real sensors before generating metadata for the virtual sensor. The determination unit checks consistency between the tentatively input virtual sensor metadata and the obtained real sensor metadata, ensuring that the metadata is generated with proper consistency from the outset rather than requiring later corrections.
Solution Approach 2:
The determination unit provides feedback by determining consistency between the tentatively input first metadata (virtual sensor metadata) and the obtained second metadata (real sensor metadata). This feedback mechanism allows the system to verify and ensure metadata consistency, guiding the generation of final consistent metadata.
2Reliability
If consistency determination is performed before metadata generation, then metadata consistency is improved, but processing time increases
Solution Approach 1:
The determination unit performs consistency determination as a preliminary action before the generation unit creates the final metadata. By checking consistency early with the tentatively input metadata, the system prevents the need for time-consuming corrections later, actually optimizing the overall processing time while ensuring consistency.

AI summary
A data generation apparatus generates first metadata to be associated with a virtual sensor. The apparatus includes an obtaining unit that obtains second metadata about a real sensor, a reception unit that receives tentatively input first metadata, a determination unit that determines consistency between the first metadata tentatively input through the reception unit and the second metadata obtained by the obtaining unit, and a generation unit that generates final first metadata based on a determination result obtained by the determination unit.
