摘要

A fault diagnosis system based on the combination of quantitative information and qualitative information is provided. The conception of QSIM constraint and the representation of interval algebra are used to transform pieces of quantitative information into qualitative one, and a small diagnosis space is obtained. This method may extend the application range of qualitative simulation in fault diagnosis field. After added the priori fault model, the system will have the ability of self-learning. An example of diagnosing compression refrigerating system is presented and the validity of diagnosis is proved.
