Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication equipment's power consumption reduction methods, such as automatic CPU frequency reduction, are limited and dependent on CPU support, failing to effectively reduce overall power consumption, especially in scenarios with low service utilization rates and redundant components.
Innovation Solution
A method and apparatus that determine and adjust the power state of boards in a telecommunications service system based on utilization thresholds, powering down boards when the utilization rate is below a startup threshold and restoring them when it exceeds a restore threshold, independent of CPU frequency reduction capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If CPU automatic frequency reduction technology is used to reduce power consumption, then power consumption is reduced, but the power consumption reduction is limited and depends on CPU support
Solution Approach 1:
The patent segments the service system into multiple independent boards, each capable of autonomous power management. Instead of relying on a single CPU's frequency reduction capability, the system divides power management across multiple board-level units that can be independently powered down, thereby reducing overall CPU dependency and expanding adaptability.
Solution Approach 2:
The patent implements dynamic board-level power management where boards can transition between active and powered-down states based on real-time service utilization rates. This dynamic approach allows the system to adapt flexibly to varying load conditions without being constrained by CPU frequency reduction limitations.
2Use of energy by moving object
If CPU frequency is reduced to save power, then power consumption decreases, but overall power consumption reduction remains limited
Solution Approach 1:
The patent segments the service system into multiple independent boards, each capable of autonomous power management. Instead of relying on a single CPU's frequency reduction capability, the system divides power management across multiple board-level units that can be independently powered down, thereby reducing overall CPU dependency and expanding adaptability.
Solution Approach 2:
The patent changes the power management parameter from CPU frequency adjustment to board-level power state transition. By switching from adjusting a single parameter (CPU frequency) to controlling multiple parameters (board power states), the system achieves significantly greater power consumption reduction effectiveness.
3Loss of energy
If boards are powered down to reduce power consumption, then energy saving increases, but system reliability may be affected
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors service utilization rates and dynamically adjusts board power states accordingly. When utilization exceeds a threshold, boards are activated; when it falls below, boards are powered down. This feedback loop ensures service reliability is maintained while maximizing energy savings.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring multiple boards and maintaining a pool of standby resources. Before actually powering down boards, the system ensures adequate capacity remains available, and boards can be rapidly activated when needed, thus maintaining reliability while achieving energy savings.
