1、Engine fault diagnosis based on multi-sensor information fusion using DempsterShafer evidence theory,2班 张,期刊名称:INFORMATION FUSION,作者单位:加拿大安大略省滑铁卢大学,ScienceDirect:荷兰Elsevier Science公司出版的期刊,是世界上公认的高品位学术期刊,影响因子,Engine fault diagnosis based on multi-sensor information fusion using DempsterShafer evidenc
2、e theory基于Dempster-Shafer证据理论的多传感器信息融合的发动机故障诊断Abstract:Engine diagnostics is a typical multi-sensor fusion problem.发动机诊断是一种典型的多传感器融合的问题。It involves the use of multi-sensor information such as vibration,sound,pressure and temperature,to detect and identify engine faults.它涉及到使用多传感器信息如振动、声音、压力和温度用以检测和识
3、别发动机故障。,From the viewpoint of evidence theory,information obtained from each sensor can be considered as a piece of evidence,and as such,multi-sensor based engine diagnosis can be viewed as a problem of evidence fusion.从证据理论的观点来看,从每个传感器获得的信息可以被视为一项证据,正因为如此,基于发动机诊断的多传感器可以被看作是证据融合的问题。In this paper we
4、investigate the use of DempsterShafer evidence theory as a tool for modeling and fusing multi-sensory pieces of evidence pertinent to engine quality.在本文中,我们讨论使用D-S证据理论作为建模工具并且融合多传感器证据和发动机质量。,We present a preliminary review of Evidence Theory and explain how the multi-sensor engine diagnosis problem
5、can be framed in the context of this theory,in terms of faults frame of discernment,mass functions and the rule for combining pieces of evidence.我们提出了一个初步审查证据理论并且解释了如何使多传感器发动机故障诊断问题可以适合这个理论环境,在故障诊断框架内,质量函数和规则又来构成证据。We introduce two new methods for enhancing the effectiveness of mass functions in mod
6、eling and combining pieces of evidence.我们引入两种新方法用来提高质量函数在建模和结合多种证据方面的有效性。,Furthermore,we propose a rule for making rational decisions with respect to engine quality,and present a criterion to evaluate the performance of the proposed information fusion system.此外,我们提出一个用来使合理决策发动机质量的规则,并对提出的信息融合系统给出了一个
7、性能的评价标准。Finally,we report a case study to demonstrate the efficacy of this system in dealing with imprecise information cues and conflicts that may arise among the sensors.最后,我们提出一个案例研究用来证明这个系统在处理可能出现在传感器上的不精确信息的线索和冲突中的有效性。,论文摘要写作的注意事项,1摘要中应排除本学科领域已成为常识的内容;切忌把应在引言中出现的内容写入摘要;一般也不要对论文内容作注释和评论(尤其是自我评价)。2.不得简单重复题名中已有的信息。3.结构严谨,表达简明,语义确切。先写什么,后写什么要按逻辑顺序来安排。句子之间上下连贯,互相呼应。摘要不分段。Furthermore Finally,4.采用“对进行了研究”“、分析了现状”等,不必使用“笔者”等作为主语。report a case study to propose a rule for5.要使用规范化的各词术语,不用非公知公用的符号和术语。6.一般不用数学公式和化学结构式,不出现插图和表格。也不用引文。7.缩写语、略称、代号,除了相邻专业的读者也能清楚理解的以外,在首次出现时,必须加以说明。,
