摘要:

貝葉斯網(wǎng)絡(luò )在解決復雜裝備中不確定性和關(guān)聯(lián)性引起的故障中具有很大優(yōu)勢,建立符合AI-ESTATE標準的貝葉斯網(wǎng)絡(luò )模型,對實(shí)現其通用性至關(guān)重要；首先介紹了AI-ESTATE標準的主要內容、體系結構和6種信息模型；其次,在對貝葉斯網(wǎng)絡(luò )進(jìn)行分析的基礎上,研究如何將公共元素模型擴展為貝葉斯網(wǎng)絡(luò )模型,詳細介紹了拓展過(guò)程并給出了拓展框圖,同時(shí)對各實(shí)體和屬性進(jìn)行了說(shuō)明；最后,針對標準中采用的EXPRESS描述語(yǔ)言編輯工具少、通用性差等問(wèn)題,采用XML語(yǔ)言對其交換文件進(jìn)行描述,使得診斷信息具備更好的可移植性和互操作性。

Abstract:

Bayesian Network has great advantages in solving the uncertainty and association fault in complex equipments,setting up the Bayesian Network Diagnostic Model according to AI-ESTATE Standard is of great importance to realize the goal of universality. Firstly,the main contents,architecture and six information models of the AI-ESTATE Standard are introduced. Secondly,extending process from Common Element Model to Bayesian Network Model is analyzed in the paper based on the analysis of Bayesian Network,at the same time,extending figure is given,each entity and attribute are introduced in detail. Finally,aiming at the problem that the EXPRESS language used in the standard has the disadvantages of less editing tools and poor utility,XML is used to describe the exchange document for its universal property,as a result,the diagnostic information are equipped with portability and interplay. 
