Mobile Asset Sensing Terminal Sleep Control for Battery Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT-based monitoring systems for mobile assets in factories face high power consumption issues due to frequent data transmission between sensor terminals and servers, leading to frequent battery replacements.
Innovation Solution
A sensing terminal equipped with a processor, communication unit, and illuminance sensor that generates and transmits state data efficiently, determining detachment from the object using illuminance values, and reduces power consumption by entering a sleep mode when detached, thereby extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor terminal transmits data frequently to server for monitoring mobile asset, then monitoring accuracy and responsiveness are improved, but power consumption increases
Solution Approach 1:
The sensor terminal transmits data periodically rather than continuously, sending sensing data at predetermined time intervals to the server. This periodic transmission reduces power consumption compared to continuous transmission while still providing regular monitoring updates, resolving the contradiction between monitoring responsiveness and energy usage.
2Reliability
If sensor terminal uses constant power to maintain operation, then device performance and reliability are improved, but battery life decreases
Solution Approach 1:
The sensor terminal dynamically adjusts its power consumption based on operational needs. The device operates at full performance when monitoring is required but enters low-power states between transmissions, allowing it to maintain reliability during active periods while extending battery life through adaptive power management.
3Loss of information
If sensor terminal processes and transmits all sensing data, then data completeness is improved, but power consumption and data transmission load increase
Solution Approach 1:
The sensor terminal extracts and transmits only the essential sensing data required for monitoring purposes rather than all raw sensor outputs. By selecting and transmitting only relevant information (such as key operational parameters and anomaly detections), the device maintains data completeness for monitoring needs while significantly reducing processing load and power consumption.
