The modeling of logic fault diagnosis problem based on petri net is the emphasis of the dissertation 2 、基于petri網的邏輯故障診斷模型是本文的核心。
Benefit from designer experience , expert system regulations are built by c language . through the inference , all fixed logic fault and most multi - line short circuit fault are detected by expert system . on that account , the design process built by c language will be a mode that can be imitated by other intelligent fault diagnosis system 對于專家系統智能故障診斷技術而言,構建專四川大學碩士學位論文家系統規則庫和設計推理機制是重點,本文采用c語言構建規則庫,然后通過精心設計的專家推理機,從而使得固定邏輯故障和大多數多線橋接故障能夠被專家診斷系統檢測出來。
Due to the shortage of petri net in fault diagnosis , this thesis brings forward logic fault diagnosis petri net model . this model was used into the lift fault diagnosis and the multi - fault and conflict problems in lift controller ' s fault diagnosis were solved successfully 針對petri網在故障診斷中的不足,在已有的故障診斷petri網理論基礎上,提出邏輯故障診斷petri網模型,并將之用到電梯控制系統故障診斷中,成功地解決了電梯控制系統故障診斷中一果多因的診斷難題。
However , because the automobile breakdown is characterized by suddenness , comprehensiveness and difference , at the time of failure detection , we still need concrete analysis of concrete conditions , that is , we should choose appropriate detection facilities or testing tools with correct logic fault analysis , and then establish the data of failure detection and diagnosis , by which we can locate the failure and carry out trouble shooting accurately and promptly 所以在檢測故障時,我們仍需要具體的情況具體分析即選擇適當的檢測設備或檢測工具輔以正確的故障分析邏輯,并在此基礎上建立故障檢測與診斷數,才能準確、及時地對故障進行定位與故障排除。汽車智能檢測系統的研究與開發目的是為了解決汽車故障的智能化檢測,而現代汽車故障診斷的基礎是汽車用傳感器的測試。
When those ptvs are sequentially loaded to cut ( circuit under test ) from intelligent fault diagnosis system , homologous prvs ( parallel response vector ) are taken back . through test response analysis by expert system , intelligent fault diagnosis system can detect all fixed ' 1 ' logic fault , fixed ' 0 ' logic fault , and detect the majority of multi - line short circuit fault 當這些ptvs從pc機中依次加載到被測電路板后,相應的prvs (并行響應向量集)可以獲取供診斷系統進行測試響應分析,從而檢測出固定邏輯故障和橋接故障。
Using petri nets theory , this thesis carries out lift controller ' s normal running petri net model and function running petri net model . it is successful to use logic fault diagnosis petri net model , which is brought forward by the thesis , into lift controller fault diagnosing 本文運用petri網理論建立了電梯控制系統正常運行故障檢測petri網模型及其功能運行故障檢測petri網模型;提出邏輯故障診斷petri網模型,并將其運用到電梯控制系統故障診斷中,取得良好效果。
