Abstract: Intelligent virtual controls (IVC) of Qin’s model is an intelligent measurement instrument unit endowed with the function of actual measurement instruments, and these units can be used as basic building blocks for all kinds of virtual measurement instrument. The several different kinds of software architecture and their influences to IVC’s integrating and reusing are discussed first. Then, IVC’s hierarchical architecture supporting plug and socket architecture, and an software architecture-based IVC integrated framework are proposed. Finally, an example of assembling virtual instrument is given.

Key words: Qin’s intelligent virtual controls, Software architecture, Virtual instrument
