PXI总线电子装备测试系统是将基于PXI总线的虚拟仪器技术,应用于航空电子装备的测试。针对航空电子装备的测试需求、系统开放性和可扩展的要求,设计研制了一套基于PXI总线的检测设备。详细说明了基于PXI总线的电子装备测试系统的硬件构成和软件设计方法。该系统以PXI内嵌主控计算机为核心,以LabVIEW软件为开发环境,并综合运用标准接口和总线技术来实现系统的综合设计。通过设计测试证明该系统方案切实、有效。
PXI bus electronic equipment test system is based on PXI bus virtual instrument technology, used in avionics testing. Aiming at the requirements of avionics testing, the openness and scalability of the system, a set of testing equipment based on PXI bus was designed and developed. The hardware structure and software design method of electronic equipment test system based on PXI bus are described in detail. The system takes PXI embedded main control computer as the core, LabVIEW software as the development environment, and comprehensively uses the standard interface and bus technology to realize the integrated design of the system. The design and test proves that the system scheme is effective and effective.
