    摘要:

    針對靜態(tài)故障樹(shù)診斷序列長(cháng)、人工可干預度差和不支持多現象并行推理問(wèn)題,提出了基于D-矩陣和Rollout信息啟發(fā)搜索算法的故障診斷策略動(dòng)態(tài)生成方法,介紹了基于TEAMS多信號流模型的D-矩陣數據獲取方法和Rollout信息啟發(fā)搜索算法的DLL獨立封裝技術(shù)、輸入輸出數據規范和動(dòng)態(tài)交互控制方法;基于此開(kāi)發(fā)的交互式智能診斷系統(IIDS)軟件平臺經(jīng)實(shí)際現場(chǎng)測試診斷驗證,對診斷現場(chǎng)出現的多種客觀(guān)條件,如系統工作模式或測試資源變化、用戶(hù)干預和多故障現象并發(fā)推理等具有很好的適應性,故障覆蓋率和隔離率指標高,對提高裝備故障診斷的效率、準確性和靈活性具有顯著(zhù)作用。

    Abstract:

    To solve the applying problems of long diagnostic sequence, poor artificial intervention and no support to parallel diagnosis of multiple fault phenomena about the static generation method for the malfunction diagnosis strategy tree, with considering the field testing and diagnosis of ship equipments,on the basis of the TEAMS multi-signal flow model data structure, the study of crack method to D-matrix and the standalone DLL files, input/output specification and interactive control method of the search algorithm intrigued by the ROLLOUT information, the dynamic generation method for the malfunction diagnosis strategy tree is designed in the paper. The generation method for the D-matrix data based on the TEAMS multi-signal flow model and the interative control method for search algorithm intrigued by the ROLLOUT information is introduced in the study. Based on the dynamic diagnosis strategy of the malfunction tree and the distributed test diagnosis methods, a platform of interactive intelligent diagnosis system ( IIDS) is developed. The system with high adaptability to the objective conditions for the diagnosis of the scene, such as system operating mode or test resource changes, user intervention and parallel diagnosis of multiple fault phenomena, it’s proved to have good effect in improving efficiency, accuracy, flexibility of equipment fault diagnosis.
