Virtual Sensor Interpolation for ZEB Environmental Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for managing indoor environmental information in Zero Energy Buildings (ZEBs) are limited as interpolated data is primarily used for visualization and not utilized for other purposes or at different times, lacking flexibility and versatility.
Innovation Solution
An environmental information management system that collects sensor values from multiple points, interpolates data to create virtual sensor values, and accumulates this information for flexible usage and retrieval at any time, enabling its application beyond visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of sensors are deployed to accurately grasp the indoor environment, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates virtual sensor data by copying and interpolating from real sensor measurements. Virtual sensors are generated at positions where no physical sensors exist, using interpolation algorithms to estimate environmental parameters. This approach provides comprehensive spatial coverage without deploying additional physical sensors, thereby maintaining measurement precision while reducing device complexity.
2Ease of operation
If interpolated environmental information is only used for visualization, then ease of operation is improved, but adaptability and versatility are limited
Solution Approach 1:
The patent makes the environmental information management system universal by enabling interpolated data to serve multiple functions. The system allows interpolated environmental information to be used not only for visualization but also for facility control, energy management, and various analytical purposes. This multi-functionality approach resolves the contradiction by expanding adaptability while maintaining ease of operation through a unified management interface.
3Productivity
If real-time visualization is the sole purpose of environmental monitoring, then productivity is improved, but loss of information occurs when data is not immediately displayed
Solution Approach 1:
The patent performs preliminary action by pre-calculating and storing interpolated environmental information in a database before it is needed. The system continuously generates and accumulates virtual sensor data, so when historical analysis or retrospective queries are required, the information is already available. This eliminates data loss and ensures that environmental information can be retrieved and utilized at any time for various purposes.
