Abstract: Since the innovative idea “rock model” was first published on 7th issue of this Journal in 2007, the research of “rock model” has made significant progress. In this paper, further study of realizing principles and key technologies of “rock model” large instrument repository is introduced. The computer expression of the “interlayer structure”, the intelligent development system model and the intelligent development principle of virtual instruments and the basic action loop of intelligent development system model are described in detail. And the scheme to realize automatic assembling of virtual instruments is discussed. The formation principle of large instrument repository, the rock management and founding based on faceted classification and knowledge discovery are analyzed. The establishment and initial application of typical “rock layer” instrument repository is introduced. The mode of design, manufacture and use of instruments is changed radically by “rock model”.

Key words: “Rock layer” instrument repository, Interlayer structure, Large instrument repository, Rock model
