基于IVI驱动的真空热试验数据采集系统软件开发

摘要

目前国内大型空间环境模拟器配备了多种型号的数据采集系统，主要负责完成对多种数据信号的综合测试。文章以Keithley 3706数据采集系统为设计对象，在VB6.0的开发环境中设计了基于IVI驱动的数据采集软件，给出了IVI驱动的设计过程及软件代码。实践表明，IVI驱动的引入提高了数据采集系统的开发效率，降低了研制成本，实现了数据采集系统的硬件无关性。%At present, a large space environment simulator is equipped with multiple models of data acquisition systems, responsible for a comprehensive test of a variety of data signals. With the Keithley3706 data acquisition system as the object, this paper discusses the principle and the composition of a data acquisition system. Based on the research of the IVI driver, an acquisition software is designed in the VB6.0 development environment.The design process of the IVI driver and the software code are presented. It is shown that the development efficiency is improved with the introduction of IVI driver, and the cost of research is notably reduced. The hardware independence of the data acquisition system is realized.
