摘要
针对在传统企业信息化建设中存在管理网络与控制网络相互独立的问题,提出了一种适用于管控一体化网络的网管系统模型。该模型根据管控一体化网络结构复杂、实时性高、稳定性强等特点,通过利用计算机网络技术、实时数据库技术和自动控制技术等将管理网络与控制网络紧密的集成在一起,解决了网络节点数据流状况难于分析、网络扩展性强引起的网络结构形式复杂多变等网络管理的问题。以实际企业管控一体化网络为例进行验证,实验结果表明该模型能够提高网络管理效率、改善网络运行状态。
More and more researchers have focused on analyzing the heart sound signals in computers.However,noise often appears in parts of heart sounds when they are recorded,therefore how to evaluate the noise level of the heart sound becomes an important problem.This paper suggests a noise evaluation index—quality index,which is defined on the cyclostationary property of the heart sounds.It can estimate the noise level accurately.If the heart sound signal acquired is too long,selecting the signal segments with larger quality index can pick out those which are less noisy,which can greatly reduce time of preprocessing,such as denoising.The quality index defined in this paper is suitable to all normal and abnormal heart sound signals,and no manual intervention is needed in the process of subsequence selection,therefore making this scheme useful in automatic analysis of heart sound signals.
