| Abstract: | A diagnosis method based on intelligent information processing is described and analyzed,which can deal with complex dynamic systems such as underwater vehicles.By quantifying the reasoning mechanism with probability information, the diagnosis results can be measured quantitatively and the diagnosis process can be controlled accurately.On the other hand,an integrated design method is proposed to deal with the information exchange between different hierarchies,which is proved to not only improve the diagnosis capability of modules and efficiency,but also make the system able to deal with some complicated faults which could not be diagnosed correctly in the past. |
