摘要
针对航电系统CNI子系统静态测试系统的不足,提出了一种类似仿真环境的动态测试方法.该动态测试系统由总线控制单元、开关矩阵单元、信号调理单元、电源单元、显示键盘单元、测试仪器仪表单元和接口面板单元组成,综合运用了动态实时仿真技术、故障注入技术和故障诊断技术,有效保证了航空电子设备测试链路的完整性,提高了航空电子设备的测试效率、实时性和可靠性,减轻了维护保障人员的劳动强度,同时达到了测试设备好用、管用和实用的要求,填补了以往静态测试系统的不足.
In view of the deficiency of the static test namic test methodof similar simulation environmentis posed of a bus control unit, a switch matrix unit, a system of CNI system of integrate avionics, a dy- put forword. The dynamic testing system is corn- signal conditioning unit, a power unit, a display keyboard unit, a test instrument unit and a interface panel unit, which using dynamic Real-time emula- tion technique, fault injection technique and fault diagnosis technique. The testing system provides an effective guarantee to integrality of the test link of integrated avionics. The test efficiency, Real-time and reliability of integrated avionics is improved by this system. The test system can reduce the labor in- tensity of the maintenance support personnel, at the same time to the requirements of test equipment to use, effective and practicalfilling the deficiency of previous static testing system.
