Innovation Solution
The implementation of a method and apparatus that controls the allotment of power input between Power Amplifiers (PAs) in radio units, utilizing both Direct Current (DC) and Photovoltaic (PV) power, where the amount of power to be transmitted by each PA is established and PV power availability is considered to optimize energy usage, allowing for the integration of renewable PV power when possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If DC power is used to power radio units, then reliable power supply is ensured, but energy savings are limited and environmental impact increases
Solution Approach 1:
The patent combines DC power and PV power into a unified power supply system for radio units. The power management unit dynamically allocates power from both sources based on availability and requirements, merging traditional grid power with renewable solar power to achieve both energy savings and reliable operation.
Solution Approach 2:
The system changes the power allocation parameters dynamically based on PV power availability, traffic load, and operational requirements. The power management unit adjusts the proportion of PV power versus DC power in real-time, optimizing energy usage while ensuring continuous reliable operation.
2Loss of energy
If PV power is integrated into radio units, then environmental friendliness improves, but power availability becomes variable due to weather conditions
Solution Approach 1:
The power management unit continuously monitors PV power availability, weather conditions, and radio unit power requirements. Based on this feedback, it dynamically adjusts power allocation strategies, ensuring optimal use of PV power when available while maintaining operational reliability during variable weather conditions.
Solution Approach 2:
The system implements dynamic power allocation where the proportion of PV power versus DC power changes continuously based on real-time conditions. The power management unit adapts the power supply configuration dynamically, transitioning between different power mixing ratios to optimize environmental performance while ensuring operational continuity.
3Productivity
If power is allocated to multiple PAs, then communication capacity increases, but total power consumption increases
Solution Approach 1:
The patent applies different power allocation strategies to different Power Amplifiers based on their individual traffic load and power requirements. The power management unit identifies which PAs have higher priority or greater power needs and allocates PV power preferentially to those units, ensuring that power is distributed according to local needs rather than uniformly.
