基于IVI驱动模式的仪器信号驱动器设计

Design of Signal-Oriented Instrument Driver Based on IVI Driving Mode

针对测试平台中仪器的互换性问题,提出一种基于IVI驱动模式的仪器信号驱动器设计方法。通过分析测试软件平台的架构,建立基于IVI(interchangeable virtual instrument)驱动模式的仪器信号驱动器,研究驱动器的结构和接口,并采用COM(component object model)组件技术完成了仪器信号驱动的设计。试验结果证明:该设计实现了对仪器驱动的面向信号调用,提高了仪器的可互换性。

For improving the interchangeability of automatic test system （ATS）, a signal-oriented instrument driver is designed based on IVI driving mode. In this paper, after analyzed the software framework of ATS, the signal-oriented instrument driver based on interchangeable virtual instrument （IVI） driving mode is established, then the structure and interface of the driver is studied and the signal-oriented instrument driver is designed by component object model （COM） technique. Experiment result demonstrates that the design can realize the signal-oriented use for instrument driver and improve the interchangeability of ATS.
