Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the ONU uses hardware modules in the acceleration channel for data processing, then data processing speed is improved, but power consumption increases
Solution Approach 1:
The patent dynamically switches between acceleration channel (hardware module) and CPU channel based on real-time service flow detection. When service flow is below threshold, the system transitions from hardware acceleration mode to CPU processing mode, enabling adaptive power consumption management that balances speed and energy usage.
Solution Approach 2:
The system changes the processing parameter by switching the active processing channel based on service flow parameters. When service flow drops below a threshold, the system changes from using hardware acceleration modules to using CPU channels, effectively changing the operational state to reduce power consumption.
2Use of energy by moving object
If the ONU enters deep energy saving state to reduce power consumption, then energy efficiency is improved, but service processing capability may be reduced
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors service flow and dynamically adjusts the processing channel. When service flow is detected below a threshold in deep energy saving state, the system activates CPU channel processing, ensuring service capability is maintained while preserving energy efficiency. The feedback loop prevents unnecessary service degradation.
3Productivity
If the ONU remains in full load running state to maintain service capability, then service processing is ensured, but power consumption increases
Solution Approach 1:
The patent segments the processing capability into two distinct channels: acceleration channel for high-performance processing and CPU channel for low-power processing. This segmentation allows the system to allocate appropriate processing resources based on actual service flow, maintaining service capability while reducing power consumption during low-demand periods.

AI summary
Examples of the disclosure relate to the field of terminal devices and provide a method and apparatus for controlling power consumption of an ONU, an electronic device, and a storage medium. The method includes: monitoring a current state of the ONU in real time, wherein the state at least includes a deep energy saving state, and data flow of the ONU in the deep energy saving state is lower than a preset threshold; and performing message processing on received data through a CPU channel and performing a power-off operation on a hardware module in an acceleration channel of the ONU when the ONU is currently in the deep energy saving state; wherein the acceleration channel is connected to a data ingress of the ONU, and the hardware module in the acceleration channel is configured to perform message processing on the received data of the ONU; and the CPU channel is a channel established between the data ingress of the ONU and a CPU and is configured to perform message processing on the received data of the ONU through the CPU. Accordingly, running power consumption of the ONU is reduced, and energy saving and emission reduction of an operator network communication system are realized.
