VXI bus是继GPIB总线之后,在PC机广泛应用的基础上,融合了VME bus和GPIB而产生的新一代模块式仪器总线。本文讨论了怎样在GPIB环境下采用VXI bus标准组建新型的自动测试系统,并结合一个基于VXI bus数据采集系统的设计实践,探讨了选用VXI bus标准需要考虑的若干重要技术问题。该系统作为机电部“七五”重点军事预研项目“计算机辅助测试(CAT)工作站”的一个重要应用子系统,于1992年元月在北京通过了部级技术鉴定,并引起了有关部门的高度重视。
VXI bus is a new generation of modular instrument bus generated by combining VME bus and GPIB after GPIB bus and based on PC’s extensive application. This article discusses how to use the VXI bus standard GPIB environment to build a new type of automatic test system and a VXI bus based on data acquisition system design practice to explore the selection of VXI bus standards need to consider a number of important technical issues. As an important application subsystem of “Computer Aided Test (CAT) Station” of the “Seventh Five-Year Plan” major military pre-research project of the Ministry of Electrical and Mechanical Services, the system passed the ministerial technical appraisal in Beijing in January 1992 and attracted the attention of relevant departments highly valued.
