摘　　要：自动飞行控制计算机故障时飞机自带系统级自检测模块只能将故障定位在自动飞控计算机,地勤人员需要将整个自动飞行控制计算机返回给供应商进行检测维修,这一过程耗时较长会降低飞机的完好出勤率,为解决该问题设计通用自动测试平台。通过分析自动飞行控制计算机的外部交联关系确定通用自动测试平台需要进行仿真的接口及功能模块;通用自动测试技术平台的硬件平台基于通用标准仪器总线架构,软件平台基于标准自动测试标记语言描述,实现硬件仪器资源的自由扩展和各软件模块的相互独立以及不依赖于硬件和操作系统的可移植性;根据自动飞行控制计算机的接口、功能及组成架构设计检测自动飞行控制计算机各个功能模块的测试方法和测试流程,使用自动测试标记语言将其编译成计算机可运行的测试程序集。该平台在试用中测试效果较好,可以实现故障模块的快速定位,缩短维修时间。The built-in test of the aircraft can identify the fault on the automatic flight control computer when the automatic flight control computer is in failure.The ground crew deliver the automatic flight control computer to supplier for testing and maintenance,which is wasting time and ineffective,so the general automatic testing platform is designed.The interface and function modules,which need to be simulated are identified by the general automatic testing platform through researching the interface relationship of the automatic flight control computer.The hardware platform of the general automatic testing technology based on general standard instrument bus architecture,and the software platform based on standard automatic test makeup language(ATML)description to realize the hardware free extension,software independence,and portability independent of hardware and operating system.According to the interface,function and composition architecture design of automatic flight control computer,the test methods and test flow of each functional module are designed,and compiled into the operational test assemble with ATML.The platform is of good effect on trial,can can realize fast locating of fault module,and shorten the maintenance time.
