| Abstract: | In this paper,the working situation identification and the fault diagnosis of big vapour jet pump vaccum system are studied. Present the conceptions of omen vector and fuzzy omen vector, basing them the way of working situation and the fault identification is given. Three kinds of fault are diagnosed and validatied. |
