中文摘要 | 機台設備漸趨高功能與複雜化,為迅速排除故障,縮短停機維護時間,透過故障診斷系統來支援維 護工作已越來越普遍;本文利用VB 程式設計一油壓故障診斷系統,結合模糊推論、VB 與Microsoft Access 資料庫,對油壓系統故障問題進行模糊診斷,查詢、儲存故障維修知識。系統包含三個部分:維修紀錄 登錄、故障資料查詢與故障診斷三個部分。維修紀錄登錄提供維修人員,在對設備進行維護後,將故障 徵兆與相關維護內容儲存於資料庫內;故障資料查詢提供使用者查詢過去發生的故障及解決辦法;模糊 診斷則提供使用者依據故障徵兆進行故障源推論。當設備發生故障,維護人員可先由故障診斷系統中查 詢是否有類似故障,若資料庫內無類似故障,則利用模糊診斷來做故障源推論,診斷結果經現場維修人 員確立驗證後,透過資訊回存系統儲存於資料庫內。 |
英文摘要 | Following the development of industrial technology, equipment is more and more complex as well as maintenance is to become more and more critical. In order to rapidly fix faults and shorten maintenance time, developing a diagnostic system to support maintenance is practicable. This paper presents a fault-diagnosis system subjected to hydraulic system by combining VB programs and Access database. The diagnostic jobs were implemented based on fuzzy set operations. This system was developed including three items: (1) maintenance data recording, (2) historical maintenance data querying and (3) fault diagnosing for new problems. The first item is designed providing maintenance personnel to record maintenance data for the known faults. The second is letting the users could query the historical maintenance data according to the given constraints such as data, key words, fault symptoms, etc. The third is an interactive deductive interface for identifying the fault sources according to the given strength of symptom occurrences. While system occur failures, maintenance personnel can query the past maintenance data first, if no similar cases exist, the diagnostic interface would be triggered to find out the possible faults. After the faults identified, maintenance would be taken and the results would be restored into the database so that the maintenance information can be reused in future. |
