摘　　要：针对航空计算机多通道数据采集和实时性的要求,对某航空计算机的信号完成自动测试功能。该自动测试系统硬件采用基于PXI(PCI eXtensions for Instrumentation)总线的测试平台,软件应用LabVIEW编写测试程序。试验验证,该系统测试效率高、实时性强、运行稳定且易操作,可满足航空计算机工作时的信号检测与故障诊断需要。To meet the multi-channel data acquisition and real-time requirements for the aviation computer, the signals of the aviation computer was tested automatically. The hardware of the automated test system （ATS） is designed based on PCI extensions for instrumentation （PXI） bus, and the software is designed by LabVIEW to complete test procedure. By experimental verification, the performance and easy operation, which can fully meet fault diagnosis. system proves high test efficiency, hard real-time, stable the needs like the aviation computer signal detection and
