摘　　要：为了提升数字光纤网络通信数据采集能力,需要进行数字光纤网络通信数据采集方法的研究。针对采用当前方法进行通信数据采集时,数据流过度集中在网络的关键节点,存在数据采集较为拥塞的问题。提出一种基于平衡树的数字光纤网络通信数据采集方法。该方法先基于时频分析理论提取数字光纤网络通信数据的特征向量,计算得出通信数据特征的均值和方差,降低特征向量局部的脉冲干扰,计算采集冗余数据的密度,组建数字光纤网络通信数据采集机制,建立路由度量模型,并以度量值最小作为约束条件完成对数字光纤网络通信数据的采集方法优化。仿真证明,所提方法数据采集精度较高,大幅度提升了数字光纤网络通信数据的采集能力。A data acquisition method for network communication of digital optical fiber is proposed based on bal- anced tree. Firstly, the feature vector for network communication data of digital optical fiber is extracted based on theory of time frequency analysis, mean and variance of communication data characteristic is calculated, and local pulse interference of feature vector is decreased. Then, the density of collected redundant data is calculated, the data acquisition mechanism of network communication of digital optical fiber is established, and route metric model is built. Finally, the optimization of data acquisition method for network of digital optical fiber with the minimum metric value as constraint condition is completed. The simulation results show that the mentioned method has high data ac- quisition accuracy. It can greatly improve acquisition capability of network communication data of digital optical fiber.
