基于GPIB-VXI控制方式的虚拟仪器自动测试系统设计

Design of virtual instrument system based on GPIB-VXI mode

在当前流行的总线连接方式中 ,VXI总线形式被自动化测试系统广泛采用 ,讨论了基于GPIB VXI控制方式的虚拟仪器测试系统的构成 ,研究了混合总线虚拟仪器测试系统的构成方案 ,由主控计算机通过GPIB总线实现对连接在该总线上的VXI总线仪器和GPIB总线仪器的控制 ,这种实现方案提高了系统构成的灵活性 ,降低了系统成本 ,使系统具有很强的通用性和可扩展性。

In current bus connection modes, VXI bus is now widely used in Automatic Test System (ATS). The system construction of virtual instrument system based on GPIB?VXI control mode is discussed. Taking an ATS for a weapon system as an example, the construction concept of hybrid bus virtual instrument test system is studied, in which the master control computer controls the VXI bus instrument and GPIB bus instrument via GPIB bus. It increases the flexibility of system construction, lowers system cost, and makes the system excellent practicable and expandable.
