Information Terminal Control Method for Normalized Power Consumption Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating energy conservation in multiple shop facilities fail to account for differences in how facilities are operated after their introduction, leading to inadequate comparison of power consumption across various locations.
Innovation Solution
An information terminal control method and system that normalizes power consumption data by accounting for environmental conditions and equipment characteristics, allowing for a fair comparison between facilities by reducing the influence of these factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If total power consumption is compared directly between shops, then comparison is simple, but evaluation accuracy deteriorates due to differences in environmental conditions and facility operation methods
Solution Approach 1:
The patent transforms the comparison approach by changing parameters from raw power consumption values to normalized values that account for environmental conditions (temperature, humidity, sunshine, precipitation) and facility characteristics. This normalization process adjusts the data to eliminate the influence of external factors, enabling accurate comparison of facility operation efficiency across different locations while maintaining computational feasibility.
2Measurement precision
If normalization based on hours of operation and shop layout size is applied, then evaluation accuracy improves, but inability to account for post-introduction operation methods limits effectiveness
Solution Approach 1:
The patent performs preliminary normalization of power consumption data by environmental conditions and facility characteristics before comparison. By pre-processing the data to remove the influence of temperature, humidity, sunshine, and precipitation variations, the system creates a standardized basis for comparison that then allows accurate assessment of different operation methods without being confounded by environmental differences.

AI summary
An information terminal control method includes (a) accepting an instruction requesting for displaying of comparison between a power consumption of first electrical facilities provided in a first establishment and a power consumption of second electrical facilities provided in a second establishment, and (b) displaying, on a display, comparison data comparing between the power consumption of the first electrical facilities and the power consumption of the second electrical facilities, the comparison data being calculated with reduced influence of a difference between an environmental condition of the first electrical facilities that influences an efficiency of the first electrical facilities and an environmental condition of the second electrical facilities that influences an efficiency of the second electrical facilities.
