基于PXI的某机载计算机检测系统的设计

Design of a PXI-based Computer Test System for a Certain Aircraft

为了对某机载计算机进行检测并能将故障定位到板,在分析比较当前2种主流测试技术的基础上,提出了一种基于PXI架构的检测系统,描述了该检测系统的体系结构及设备选型,同时设计了该机载计算机的检测流程、故障判据数据库和故障诊断软件模块以满足检测要求,其中故障判据数据库已经过调试,可顺利运行。

For testing a certain airborne computer and locating its fault to the concrete board, a PXI configuration based test system was presented by analyzing two essential test techniques currently used. The test system architecture and choosing for its devices were described, and the test flow process, fault detection database and fault diagnosis software module of this airborne computer were designed to meet the demand of test, where the fault detection database was debugged, operating well.
