| Abstract: | A fault detection and diagnosis method based on the rule and time variation was presented based on the normal diagnostic expert system. The knowledge representation method and diagnostic reasoning strategies were described. A fault diagnostic prototype system was developed in Windows NT. The architecture and function of the prototype system were introduced. |
