Application of ESKD supported virtual instrument in distance engine fault diagnosis

Virtual instrument is help to distance fault diagnosis and exclusion of large scale equipments as engines. In order to achieve distance automate control on engine fault diagnosis, a kind of virtual instrument fault diagnosis method based on Expert System supported Knowledge Database (ESKD) of double database cooperating mechanism was presented. The internet technology was also used for distance interactive operation and transmission of measure data. Then an intelligent engine fault diagnosis and exclusive system was designed. The specific experiment on some engine fault diagnosis shows that the system has high accuracy and practicality, and easy to operate and use.
