Representation of Measuring Instrument by Abstraction of the Functions in Virtual Instrumentation

摘要

A virtual measurement system is widely used as a professional engineering tool by an extension of function and interface of an actual measuring instrument. The user interface characterized in the virtual world presents rich operations of a measuring instrument. This paper describes the technique of applying object-oriented concept and extracting each function of measuring instrument as an object to unify the control. The object-oriented abstraction (OOA) of measuring instrument reconstructs and integrates the function. The OOA absorbs the difference of the operations caused by manufacturing company, model, and terminology. The OOA operates the measuring instrument by controlling the reconstructed functions. Then, any kinds of measuring instrument will be controlled with unified user interface by using the OOA.
