基于综合施工成本模糊判定的RRU-BBU供电设计方法

Design of RRU-BBU Power Supply Based on Fuzzy Decision of Comprehensive Construction Cost

针对现有通信电源保障体系难以适应RRU-BBU分布式组网方式等问题,提出基于综合施工成本模糊判定供电模式的方法。首先分析分散供电、集中供电等经典分布式基站供电模式的综合施工成本;然后结合室内覆盖不同场景,设计模糊判定的隶属度函数及其子集,实现基于综合施工成本模糊判定的RRU-BBU供电设计方法。应用验证结果表明:该方法能够节省投资,优化供电性能。

As the existing communication power supply security system is difficult to adapt to the RRU-BBU distributed networking, a fuzzy decision method of power supply mode based on comprehensive construction cost was proposed. Firstly, the comprehensive construction costs of distributed power supply, centralized power supply and other classic power supply modes were analyzed. Secondly, combined with indoor coverage of different scenes, membership functions and subset of fuzzy decision were designed to realize RRU-BBU power supply design method based on fuzzy comprehensive judgment of construction cost. Finally, application validation was demonstrated. The results show that the proposed method can save a lot of investment and optimize the power supply performance.
