Gateway Power Control During Network Backup Power Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gateway devices face challenges in managing power transitions during primary power disruptions, balancing user experience with the need to minimize backup power consumption to extend battery life, while ensuring continuous operation and minimizing disruptions.
Innovation Solution
The system determines active and inactive components in a gateway device and transitions to a low power mode by reducing modulation rates, throttling power to active components, and powering down inactive ones, using backup power efficiently to extend battery life during disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gateway device operates in normal power mode during primary power disruption, then user experience is maintained, but backup power is consumed rapidly
Solution Approach 1:
The gateway device dynamically transitions between normal power mode and low power mode based on the duration of primary power disruption. Active components are selectively powered down after a threshold time period, allowing the system to adapt its power consumption characteristics to extend backup power duration while maintaining user experience during the initial disruption period
Solution Approach 2:
The system changes operational parameters by reducing modulation rates and transitioning from higher-order modulation schemes to lower-order schemes, thereby reducing power consumption of active components while maintaining essential communication functions during backup power operation
2Duration of action of moving object
If the gateway device reduces power to active components immediately, then backup power duration is extended, but user experience deteriorates
Solution Approach 1:
The gateway device implements a time-based strategy where active components continue to receive full power during an initial threshold period to maintain user experience, and only after this period expires does the system transition to reduced power mode, thereby preliminarily preserving service quality before extending backup power duration
3Speed
If the gateway device maintains high modulation rates, then data transmission speed is improved, but power consumption increases
Solution Approach 1:
The system changes modulation rate parameters by transitioning from high-order modulation schemes to lower-order schemes during backup power operation, thereby accepting reduced data transmission speed in exchange for significantly reduced power consumption of active components
