[Abstract] Based on time series analysis and BP neural networks, a fault diagnosis system is built for ve-
hicle transmission gears. By time series analysis and eigenvectors extraction on operation status signals of trans-
mission gears, which are taken as inputs for neural network training, the operation status identification and fault
diagnosis for transmission gears are realized. In a fault diagnosis on the gears of a real transmission, the system
can accurately identify the operation status (running in, worn or fault). The result shows that the system is ef-
fective and feasible.

本文提出了一种新的推理机制来确定规则的专业知识为基础的Petri网适当的开关操作（RKPN）方法。一个26馈线的实际分配制度被指定为揭示了发展与计算机模拟方法的有效性。拟议的推理机制可以成功地解决馈线过载/故障应急根据负载的变化，从温度升高导致的。
This paper presents a novel inference mechanism to determine appropriate switching operations by the rule-expert knowledge-based Petri net (RKPN) approach. A practical distribution system with 26 feeders is specified to reveal the effectiveness of the developed methodology with computer simulations. The proposed inference mechanism can successfully solve feeder overload/fault contingency based on the load variations resulting from temperature rises. (2011-03-09, PDF, 652KB, 下载3次)

本体推理是语义网研究的一个热点问题，目前大多数查询系统都是专家系统，但在
专家系统中，知识的表现形式都存在各种不足，本文在借鉴原有专家系统优点的基础之上，
介绍了一个基于SWRL 推理机制的框架，它弥补了专家系统中的不足之处，解决了以往的
本体不能表示“if...then...”这样句式规则的缺点，另外利用本体技术使我们的系统在其它类似
的系统中可以重复使用。
Ontology inference is a hot issue in the studies of Semantic Web. At present, Most inquiry systems are
all expert systems, but there are various deficiencies in expression forms of expert systems knowledge.
In this paper, on the basis of referring to the advantages of original expert systems, a framework of
SWRL-based reasoning mechanism is introduced. It makes up for the deficiency of expert systems and
solve the shortcoming that the original ontology can not express the rule sentences such as”if... then ...”.
In addition, our systems can be used repeatedly in other similar systems by the ontology technology. (2009-03-15, PDF, 264KB, 下载53次)
