| Abstract: | A kind of fault diagnosis expert system of ultracentrifuge is researched.This system adopts man-machine dialogue mode,sampling the real-time data of the ultracentrifuge’s operation or inputing fault artificially on the basis of expert system knowledge;reasoning with Bayesian network method,thus getting the reasons of faults and their possible probability.It makes the maintainence more targeted,realizing fault diagnosis of ultracentrifuge intelligently,and improving the reliability and safety of equipment. |
