Abstract: In order to solve Knowledge Unity(KU) problem in remote collaborative fault diagnosis system, by researching the characteristics of fault diagnosis knowledge and object-oriented method, this paper puts forward mathematical model of metadata integration for diagnosis knowledge, and adopts improved virtual approach to heterogeneous metadata integration to realize diagnosis knowledge unity. Explanation of a certain diagnosis knowledge integration process on grinder proves that the method can realize diagnosis knowledge unity, and improve the efficiency for knowledge searching and transferring.
