Interchangeable Virtual Instrument Driver Based on COM
-
摘要: 提出了基于COM(Component Object Model)的可互换虚拟仪器驱动器的模型,分析了其实现互换的方法,并提出了在该模型下的仪器仿真驱动方案,最后将该模型的驱动器和现有VPP(VXI Plug&Play)、IVI(Interchangeable Virtual Instrument)驱动器进行了对比分析,其结果表明,基于COM的可互换虚拟仪器驱动器在互换性、平台适应能力、远程访问能力以及仿真能力等方面具有更加优良的综合性能. Abstract: A new structure of interchangeable virtual instrument driver was proposed based on COM, a commonly used software component. Analysis was done to explain how the new structured instrument driver implements interchangeability and simulation. At last, some comparisons of performance among VPP driver, IVI driver and IVI-COM driver was listed to illustrate the superiority of IVI-COM structure, such as interchangeability, platform adaptability, remote accessing ability, simulation capability, etc.
