用Bayes网络对光纤接入网供电系统故障的监控

Bayes Fault Detection for Power Supply System of Optical Access Networks

供电是光纤接入网中的一个重大技术问题。文中讨论了供电的两种方式 ,即网络供电方式和本地供电方式。对于光纤接入网 ,本地供电结构是一种较为理想的方案 ,但对本地供电网络监控则又是一个技术难点。文中设计了一种采用Bayes网络的电源监控系统网络结构 ,对网络进行了理论分析 ,并给出了具体的实现方案。

Power supply is a significant technology issue in optical fiber transmission network. Two methods of power supply systems including network power supply and local power supply systems are discussed in this paper. Local power supply system is optimal choice in optical access network.This paper proposes a structure of power supply monitoring system using Bayes network considering fault detection of power supply system in optical access network.Theoretical analysis is made and an implemention scheme is presented.
