摘　　要：飞控计算机是现代飞机数字化飞行控制系统中的核心;因此,对飞控计算机及其部件进行高质量的测试非常重要;某飞控计算机主要由多型数字模块组成;为满足这些数字模块的批量生产测试需求,在研究测试方法的基础上,设计和实现了一种数字模块测试设备(DCT)该设备基于PXI总线实现,测试程序集(TPS)使用LabVIEW开发;从硬件和软件两个方面阐明了DCT的设计方法和实现原理;该设备测试效率高,性能稳定,界面友好,维护方便,易于扩展。经检定及实际应用,表明该设备满足测试需求中33类1000余项测试的指标要求,且设备整体运行良好,测试效率超过10块/小时,取得了良好的效果。Flight control computer is the kernel subsystem of aircraft flight control system in modern times. Therefore, it is an impor- tant method to test flight control computer and its subassembly. A flight control computer is composed of manifold digital cards. For meet- ing test requirements of manifold digital cards for batch production, based on research of the test method, design and realize a Digital Card Test--equipment （DCT）. The realization of DCT based on PXI bus, and the design of Test Programe Set （TPS） based on LabVIEW. This paper describes the methods of design by the hardware and software. The DCT is efficient, reliable, steady, and convenient to maintenance and expandable. The calibration and field running results indicate that the equipment meets the test requirements （33 kinds, more than 1000 items）. The testing efficiency of DCT is more than 10 digital--cards an hour, and achieved good results.
