11、IONAL ELECTROTECHNICAL COMMISSION _ ARTIFICIAL INTELLIGENCE EXCHANGE AND SERVICE TIE TO ALL TEST ENVIRONMENTS (AI-ESTATE) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National
12、Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly A
13、vailable Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental
14、 organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on techn
15、ical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IE
16、C National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international unifor
17、mity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) I
18、EC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC sha
19、ll not be held responsible for identifying any or all such patent rights. International Standard IEC/IEEE 62243 has been processed through IEC technical committee 93: Design automation. The text of this standard is based on the following documents: IEEE Std FDIS Report on voting 1232 (2002) 93/214/F
20、DIS 93/220/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives. The committee has decided that the contents of this publication will remain
21、unchanged until 2007. BS IEC 62243:2005 3 IEC/IEEE Dual Logo International Standards This Dual Logo International Standard is the result of an agreement between the IEC and the Institute of Electrical and Electronics Engineers, Inc. (IEEE). The original IEEE Standard was submitted to the IEC for con
22、sideration under the agreement, and the resulting IEC/IEEE Dual Logo International Standard has been published in accordance with the ISO/IEC Directives. IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE
23、-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of
24、the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of an
25、IEC/IEEE Dual Logo International Standard is wholly voluntary. The IEC and IEEE disclaim liability for any personal injury, property or other damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or
26、 reliance upon this, or any other IEC or IEEE Standard document. The IEC and IEEE do not warrant or represent the accuracy or content of the material contained herein, and expressly disclaim any express or implied warranty, including any implied warranty of merchantability or fitness for a specific
27、purpose, or that the use of the material contained herein is free from patent infringement. IEC/IEEE Dual Logo International Standards documents are supplied “AS IS”. The existence of an IEC/IEEE Dual Logo International Standard does not imply that there are no other ways to produce, test, measure,
28、purchase, market, or provide other goods and services related to the scope of the IEC/IEEE Dual Logo International Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments
29、 received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not whol
30、ly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. In publishing and making this document available, the IEC and IEEE are not suggesting or rendering professional or other services for, or on behalf of, any perso
31、n or entity. Neither the IEC nor IEEE is undertaking to perform any duty owed by any other person or entity to another. Any person utilizing this, and any other IEC/IEEE Dual Logo International Standards or IEEE Standards document, should rely upon the advice of a competent professional in determini
32、ng the exercise of reasonable care in any given circumstances. Interpretations Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate a
33、ction to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating
34、Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments for revision of IEC/IEEE Dual Logo International Standards are welcome from any interested party, regardless of membership a
35、ffiliation with the IEC or IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE-SA Standards Board, 445 Hoes Lane, P

41、set of specifications for data interchange and for standard services for thetest and diagnostic environment. The purpose of AI-ESTATE is to standardize interfaces betweenfunctional elements of an intelligent diagnostic reasoner and representations of diagnostic knowledgeand data for use by such diag
42、nostic reasoners. Formal information models are defined to form thebasis for a format to facilitate exchange of persistent diagnostic information between two reasoners,and also to provide a formal typing system for diagnostic services. This standard then defines theservices to manipulate diagnostic
43、information and to control a diagnostic reasoner.Keywords: AI-ESTATE, diagnosis, diagnostic interference, diagnostic model, diagnostic services,dynamic content, fault tree, knowledge exchange, system testBS IEC 62243:2005 5 This AI-ESTATE standard provides a formal framework for exchanging diagnosti

In addition, software interfaces are defined whereby diagnostic tools can be developed to process
45、the diagnostic information in a consistent and reliable way.IEEE IntroductionBS IEC 62243:2005 6 Artificial intelligence exchange and service1. OverviewThe Artificial Intelligence Exchange and Service Tie to All Test Environments (AI-ESTATE) standardwas developed by the Diagnostic and Maintenance Co
46、ntrol (D however, such implementations may not be portable. As shownin Figure 1, a diagnostic model can be moved from one AI-ESTATE implementation to another bytranslating it into the interchange format. Another AI-ESTATE implementation can then utilize thisinformation as a complete package by trans
47、lating the data and knowledge from the interchangeformat to its own internal form.The translation step is not a requirement; an AI-ESTATE implementation may use the interchangeformat for its own internal form.Software specifications defined in this standard will ensure the interchangeability of diag
48、nosticreasoners through the definition of encapsulated services. This will allow diagnostic reasoners to beinterchanged within an AI-ESTATE conformant system with no eect on the other elements of thesystem.1.1 ScopeThe AI-ESTATE standard defines formal specifications for supporting system diagnosis.
49、 Thesespecifications support the exchange and processing of diagnostic information and the control ofdiagnostic processes. Diagnostic processes include, but are not limited to, testability analysis,diagnosability assessment, diagnostic reasoning, maintenance support, and diagnostic maturation.1.2 PurposeThe AI-ESTATE standard provides formal models of diagnostic information to ensure unambiguousaccess to an understanding of the information supporting system test and diagnosis. The standardunifies and expands on the specifications published in IEEE Std 1232T
