Blind separation technique of modulatory fault source signal 调制故障源信号盲分离技术
Whereas , the joint angle method , which could improve the q - statistic plots method , was used to isolate the fault source on line employing the history fault knowledge 联合角度法改进了传统的贡献图的诊断方法,通过对故障库中的故障知识的利用,能够在线的分离出发生故障的传感器。
2 an integrated framework for process monitoring and fault diagnosis is presented , which combines independent component analysis ( ica ) for feature extraction and support vector machine ( svm ) for identification of different fault source ( 2 )提出了一种基于独立分量分析( ica )和支撑向量机( svm )对系统性能进行监控的整体框架,这一框架包括特征提取和故障识别两部分。
In order to know the accurate location of the fault source , lower the calculating quantity of the supervise software , and increase the efficiency and accurate rate of the fault diagnosis , the level analyzing method is used in the fault diagnosis of the baggage transfering system 为了得到准确的故障发生源,降低监控软件的运算量,提高故障诊断的效率和准确率,将故障层次分析法用于行李中转系统的故障诊断。
Knowledge about the faults of a process control system is obtained automatically by rough set reduction . an entropy - based criterion is used to measure the uncertainty of it . methods of forward and backward fault diagnosis and how to build up decision tables for each fault source are given 利用粗糙集进行故障知识的发现,寻找系统各个故障源信号之间合理的逻辑关系,提出了一种构造逻辑故障树的智能方法,并给出了相应的故障树评价标准。
