摘要
大型自动测试系统中使用的开关模块包括多种型号,来自不同厂商。实现测试程序与具体物理开关仪器控制指令无关,可以提高测试程序的可重用性、可移植性和仪器的互换性。基于虚拟仪器可互换(IVI)技术的思想,分析了实现仪器可互换的技术框架,提出了开关类驱动的设计要求,最后通过一个工程上的实例说明了实现仪器可互换的开关类驱动的具体开发过程。
Large-size integrated automatic test system includes multiple types of switch models from different instrument vendors.The independence of the test program from the physical switches control codes promotes reusability and portability of the test program,as well as the instrument interchangeability.Basing on the idea of the interchangeability of virtual instrument（IVI） technology,the software framework implementing instrument interchangeable technology was put forward,as well as the design idea of the switch class driver.An engineering example illustrated the developing process of the class driver and its physical driver.
