Solution Overview
Problem
Conventional air-conditioning control systems struggle to adaptively control air conditioners when environmental sensors are moved due to changes in layout, leading to inaccurate environmental information acquisition and potential degradation of the area's environment.
Innovation Solution
An air-conditioning control system that groups environmental sensors based on correlation coefficients, regularly calculates these coefficients, and resets groups associated with sensors that no longer meet a threshold, allowing for adaptive control of air conditioners and accurate environmental information acquisition even when sensors are moved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If environmental sensors are mounted on shelves or equipment to acquire environmental information close to that experienced by a body, then measurement precision is improved, but device complexity increases due to the need for wireless communication capabilities and placement coordination
Solution Approach 1:
The environmental sensors automatically perform self-grouping based on correlation coefficients of their measured environmental information, eliminating the need for manual placement configuration or complex communication coordination. The sensors autonomously determine their spatial relationships and form groups without external intervention, reducing system complexity while maintaining measurement precision.
Solution Approach 2:
The system uses correlation coefficients as a parameter to automatically group sensors based on the similarity of their environmental measurements. By changing from manual placement-based grouping to correlation-based automatic grouping, the system reduces complexity while maintaining or improving measurement accuracy through data-driven spatial relationships.
2Adaptability or versatility
If conventional air-conditioning control systems use fixed sensor-group assignments, then device complexity is reduced, but adaptability deteriorates when sensors are moved due to layout changes
Solution Approach 1:
The system continuously calculates correlation coefficients between environmental information from different sensors and uses this feedback to dynamically adjust sensor groupings. When sensors are moved, the changed correlation patterns automatically trigger regrouping, enabling the system to adapt to layout changes without manual intervention while maintaining manageable complexity through automated feedback loops.
Solution Approach 2:
The sensor groupings transition from static, pre-assigned configurations to dynamic, correlation-based assignments that automatically adjust when sensors are moved. This dynamic approach allows the system to adapt to layout changes while the automated correlation calculation and regrouping processes keep the overall system complexity manageable.
3Adaptability or versatility
If the system regularly calculates correlation coefficients for all sensors, then adaptability is improved, but processing load increases
Solution Approach 1:
The system segments sensors into groups based on correlation coefficients and performs calculations primarily within these groups rather than across all sensors universally. This segmentation reduces the overall processing load while maintaining adaptability, as the correlation calculations are localized to smaller sensor subsets that share similar environmental characteristics.
Solution Approach 2:
The system performs correlation coefficient calculations selectively rather than continuously for all sensor pairs. By calculating correlations only when necessary (e.g., when regrouping is triggered or at scheduled intervals) and only for relevant sensor combinations, the system achieves sufficient adaptability while avoiding excessive processing loads from constant full-system calculations.
