The modeling of logic fault diagnosis problem based on petri net is the emphasis of the dissertation 2 、基于petri网的逻辑故障诊断模型是本文的核心。
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 对于专家系统智能故障诊断技术而言,构建专四川大学硕士学位论文家系统规则库和设计推理机制是重点,本文采用c语言构建规则库,然后通过精心设计的专家推理机,从而使得固定逻辑故障和大多数多线桥接故障能够被专家诊断系统检测出来。
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 针对petri网在故障诊断中的不足,在已有的故障诊断petri网理论基础上,提出逻辑故障诊断petri网模型,并将之用到电梯控制系统故障诊断中,成功地解决了电梯控制系统故障诊断中一果多因的诊断难题。
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 所以在检测故障时,我们仍需要具体的情况具体分析即选择适当的检测设备或检测工具辅以正确的故障分析逻辑,并在此基础上建立故障检测与诊断数,才能准确、及时地对故障进行定位与故障排除。汽车智能检测系统的研究与开发目的是为了解决汽车故障的智能化检测,而现代汽车故障诊断的基础是汽车用传感器的测试。
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 当这些ptvs从pc机中依次加载到被测电路板后,相应的prvs (并行响应向量集)可以获取供诊断系统进行测试响应分析,从而检测出固定逻辑故障和桥接故障。
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 本文运用petri网理论建立了电梯控制系统正常运行故障检测petri网模型及其功能运行故障检测petri网模型;提出逻辑故障诊断petri网模型,并将其运用到电梯控制系统故障诊断中,取得良好效果。
