Research Of Debugging Expert System About Power New Units Based On PDA

This paper detailedly analysed the latest research situation and development trend about fault diagnosis expert system,discussed the significance about power station unit equipment fault diagnosis.Traditional diagnosis expert system is developed on the desktop computers, it's difficult to meet the staff in field work environment real-time fault diagnosis needs.This paper studid fault diagnosis expert system based on PDA's implementation is the same as an expert who can walk.It is very easy to online and collaboration,so it has the broad development prospects.This thesis project mainly includes the following contents:The overall design for fault diagnosis expert system.In view of PDA limited performance,This paper creatively built structure tree with Fault Tree Analysis theory.Structure tree is used for fault diagnosis paths,it greatly improves PDA expert system diagnostic speed.Software realization.Both development and implementation of the knowledge database and reasoning machine and interface design are included in this paper. In short, PDA with the expert system is a handy PDA devices, especially a full of intelligent mobile devices, is a portable expert for power station debugging personnel, the unit operation staff and other related personnel.
