Intelligent Power Management for Movable Object Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring devices powered by batteries face frequent recharging or replacement due to high power consumption, which impairs their extended usage and efficiency in detecting motion and location of movable objects.
Innovation Solution
Implementing intelligent power management by transitioning through operational states with varying power requirements, allowing the device to conserve energy by switching to higher power states only when necessary to achieve specific objectives, such as data collection and communication, using sensors like accelerometers and GPS for event detection and location determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the monitoring device operates continuously in high power states to ensure accurate detection and communication, then the measurement precision and reliability are improved, but the battery life deteriorates due to high power consumption
Solution Approach 1:
The monitoring device dynamically transitions between different operational states (sleep, standby, active) based on detected events. During normal operation, the device remains in low-power states, but automatically transitions to high-power active states when events are detected, ensuring measurement precision is maintained only when necessary while extending battery life through adaptive power management
Solution Approach 2:
The device implements periodic sampling and event-driven activation rather than continuous operation. Sensors periodically check for events, and the device activates communication and high-precision measurement functions only during detected events, reducing overall power consumption while maintaining detection accuracy when needed
2Duration of action of moving object
If the device frequently transitions between operational states to optimize power consumption, then the battery life is extended, but the device complexity increases due to state management requirements
Solution Approach 1:
The monitoring device automatically manages its own power states based on event detection without requiring external control. The device self-transitions between sleep, standby, and active states based on sensor inputs and internal event detection logic, reducing the need for complex external power management circuitry while extending battery life through intelligent autonomous state management
3Use of energy by moving object
If the device remains in sleep state to conserve energy, then the power consumption is reduced, but the response time to detect events deteriorates
Solution Approach 1:
The monitoring device segments its operational modes into sleep state with periodic sampling and active state with full monitoring. During sleep state, the device performs low-power periodic checks, and upon detecting an event, immediately transitions to active state for full-speed monitoring and communication, thus reducing overall power consumption while maintaining rapid event detection capability when needed
Data Source
AI summary
Sensor data characterizing an event associated with a movable object is received. Based on the sensor data, an objective from a plurality of predefined objectives for monitoring the movable object is selected. A series of operational states having increasing power requirement levels is transitioned through. At each operational state, whether the selected objective is achievable using a respective method associated with the respective operational state and respective power requirement level is determined.
