DEVELOPMENT OF VIRTUAL INSTRUMENT BASED ON COMPONENT TECHNOLOGY

摘要

In the Virtual Instrument, software is core. In the software design of Virtual Instruments, applying component technology can reduce difficulty, reusability, and improve the efficiency of software development. According to the demand of design of Virtual Instrument, this paper applies the technology of component development and designs a dial component by using Visual C++. The Virtual dial is simulated to display value of voltage, electricity, press, and so on. This component can be used in the design of software based on Virtual Instrument.
