针对目前自动测试设备的通用性设计,提出了一种基于PXI总线的测试平台。文中对PXI测试系统、接口适配器和开关网络进行了说明;介绍了测试软件和故障诊断系统的设计;分析了该系统设计过程中面临的通用性、故障诊断与定位等问题。其设计思想和方案对于机载计算机通用测试平台的研制具有一定指导意义。
Aiming at the common design of automatic test equipment, a test platform based on PXI bus is proposed. In this paper, the PXI test system, interface adapter and switch network are described. The design of test software and fault diagnosis system is introduced. The problems of universality, fault diagnosis and location are also analyzed. The design ideas and programs for the development of a common platform for airborne computer testing has a certain significance.
