Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic inspection systems for meters, such as flow and power meters, face challenges in reducing power consumption and measurement time due to environmental disturbances like sunlight, which affect optical sensor adjustments, leading to increased power usage in exposure adjustments.
Innovation Solution
An automatic inspection system with a measurement device that includes a sensor unit, parameter management unit, and data collection device, where the data collection device generates parameter determination information to set exposure parameters for the measurement device, reducing the time required for exposure adjustments and thus lowering power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If exposure adjustment is repeatedly performed to adapt to environmental changes, then measurement accuracy is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary exposure adjustment based on environmental light conditions before actual measurement begins. The control unit adjusts exposure parameters in advance according to detected ambient light levels, so that when measurement starts, the optimal exposure is already set, avoiding repeated adjustments during measurement and reducing power consumption while maintaining accuracy
Solution Approach 2:
The measurement device autonomously monitors environmental light conditions and automatically adjusts exposure parameters without requiring repeated manual or system-wide adjustments. The device serves itself by detecting environmental changes and self-correcting exposure settings, reducing the frequency of adjustments and thereby lowering power consumption while maintaining measurement precision
2Measurement precision
If exposure adjustment processing is performed to adapt to environmental conditions, then measurement accuracy is improved, but measurement time increases
Solution Approach 1:
Exposure parameters are adjusted in advance based on environmental light conditions before the measurement process begins. By pre-setting the optimal exposure according to ambient light levels detected prior to measurement, the system eliminates the need for time-consuming exposure adjustments during the actual measurement, thus maintaining accuracy while reducing measurement time
Solution Approach 2:
The system performs exposure adjustment periodically based on environmental changes rather than continuously or repeatedly during each measurement. By monitoring light conditions and adjusting exposure only when environmental changes warrant it, the system maintains measurement accuracy while minimizing the frequency of adjustments and reducing overall measurement time
