Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for collecting operation data from refrigeration cycle apparatuses set the same data collection interval for all controls, leading to inappropriate data collection for each control.
Innovation Solution
A control apparatus with a data-collecting unit and a collection-interval-determining unit that sets different data collection intervals based on the setting contents of each control, allowing for appropriate data collection for each control by determining collection intervals based on priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same data collection interval is set for all controls, then the system operation is simple, but the data collection appropriateness for each control deteriorates
Solution Approach 1:
The patent segments the unified data collection process into control-specific sub-processes. Each control has its own data collection interval determined independently based on its setting content and priority level. This segmentation allows appropriate data collection for each control while maintaining overall system manageability through automated priority-based interval determination.
Solution Approach 2:
The patent implements dynamic data collection intervals that automatically adjust based on control priority and setting content. Instead of static uniform intervals, the system dynamically determines optimal intervals for each control, enabling appropriate data collection without manual configuration for each control type.
2Manufacturing precision
If different data collection intervals are set for each control, then the data collection appropriateness for each control is improved, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically determining data collection intervals based on control priority and setting content. The control apparatus autonomously configures appropriate data collection parameters without requiring manual intervention or complex external configuration, thereby achieving appropriate data collection while minimizing system complexity.
Solution Approach 2:
The patent changes the parameter of data collection interval from a fixed uniform value to variable values determined by control priority and setting content. This parameter transformation enables appropriate data collection for each control while the automated determination process prevents complexity increase through systematic interval assignment.
3Measurement precision
If data collection frequency is increased for all controls, then the measurement precision is improved, but the energy consumption increases
Solution Approach 1:
The patent applies local quality by setting data collection frequency according to the specific needs of each control. High-priority controls with critical setting contents receive higher measurement precision through more frequent data collection, while lower-priority controls use reduced collection frequencies. This localized quality adjustment optimizes energy consumption while maintaining necessary measurement precision for each control.
Solution Approach 2:
The system applies partial action by collecting data at high frequency only for controls that require it based on their priority and setting content. Instead of excessive uniform high-frequency collection for all controls, the system applies appropriate measurement intensity selectively, reducing overall energy consumption while maintaining precision where necessary.

AI summary
A control apparatus is communicably connected to a first apparatus to perform a control on the first apparatus. The control apparatus includes a data collecting unit, a collection interval determining unit, and a storing unit. The data collecting unit collects, by polling and from the first apparatus, data in order to perform the control. The collection interval determining unit determines, based on a setting content of the control, a collection interval of the data collected by the data collecting unit. The control apparatus performs a plurality of the controls on one first apparatus. The storing unit stores, for each of the controls, one data item or a plurality of data items constituting the data. The storing unit further stores, for each of the data items, the collection interval.
