Solution Overview
Problem
Existing systems set the same data collection interval for all controls in refrigeration cycle apparatuses, leading to inappropriate data collection for individual controls.
Innovation Solution
A control apparatus that determines individual data collection intervals for each control based on the setting content, allowing for differentiated data collection intervals for each control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same data collection interval is set for all controls in refrigeration cycle apparatuses, then the system configuration is simple, but appropriate data collection cannot be performed for each control
Solution Approach 1:
The patent segments the data collection process by creating separate collection intervals for each control type. The control device divides the monolithic data collection approach into multiple controlled intervals (first collection interval for first control, second collection interval for second control, etc.), allowing each control to have optimized data collection timing based on its specific requirements.
Solution Approach 2:
The patent implements dynamic data collection intervals that can be adjusted independently for different controls. The control device dynamically sets the first collection interval and second collection interval based on the specific requirements of each control, making the system adaptable rather than static.
2Reliability
If data collection intervals are set individually for each control, then appropriate data collection is achieved, but the control system becomes more complex
Solution Approach 1:
The control device segments the data collection system into multiple independent collection processes, each with its own interval settings. This segmentation allows reliable data collection for each control without requiring a complete redesign of the entire system, as each segment can be managed independently.
Solution Approach 2:
The patent applies local quality by setting different data collection intervals tailored to the specific needs of each control. The first control receives data at the first collection interval while the second control receives data at the second collection interval, ensuring each control gets the appropriate data frequency for its reliability requirements.
3Measurement precision
If frequent data collection is performed for all controls, then control precision is improved, but energy consumption and system load increase
Solution Approach 1:
The patent implements dynamic data collection intervals that adjust the collection frequency based on the specific requirements of each control. This dynamic approach ensures high measurement precision for controls that need frequent data while reducing collection frequency for controls that can tolerate lower updates, thereby optimizing energy consumption.
Solution Approach 2:
The control device changes the time parameter (collection interval) based on control-specific requirements. By setting different first and second collection intervals, the system optimizes the balance between measurement precision and energy consumption, collecting data frequently only when necessary for each specific control.

AI summary
There is a problem that the same data collection interval is set for all controls in a refrigeration cycle apparatus at a time of polling. A control apparatus (10) is communicably connected to a first apparatus (30, 30a, 30b, 30c) to perform a control on the first apparatus (30). The control apparatus (10) includes a data-collecting unit (11) and a collection-interval-determining unit (12). The data-collecting unit (11) collects, by polling and from the first apparatus (30), data for performing the control. The collection-interval-determining unit (12) determines, on the basis of a setting content (SU, SU1, SU2, SU3, SU4) of the control, a collection interval (CI) of the data collected by the data-collecting unit (11).
