针对民用大型飞机新型航空电子设备的动态测试需求,提出了一种基于工控机的动态模拟激励环境的设计方法,并应用该方法建立了通信导航系统的动态模拟环境;该方法通过对现代飞机总线数据、信号交联关系及电气特性进行分析,提出由工控机作为核心控制单元,应用通用激励模块建立飞机内部信号激励环境,为航电设备测试提供所需的运行环境;基于该方法设计的通信导航系统运行模拟环境可以很好地实现航电设备的激励,极大地缩短测试所需时间,有效地减少人为分析、处理数据引起的测试差错,具备极高的实用意义。
For the dynamic test requirements of new large civil aircratt avionics, a method based on IPf2 ot the dynamic simulation incen- tive environment is proposed, and a dynamic simulation environment of communications and navigation systems is established by this method. In this method , modern aircraft bus data, signal crosslinking relations and electrical characteristics are analyzed. The IPC which is the core control unit controls the common excitation signal excitation module to build aircraft interior incentive environment. This environment can provide appropriate runtime environment for the testing of avionics. A dynamic simulation environment of communications and navigation systems is established based on this method successfully, and this system also can cut down testing time, and reduce the artificial error about the data processing and analysis, so it has important application value.
