在先进的综合化航空电子系统设计中,跨平台通信的组织将直接体现使命任务的需求。通过功能流程框图将航空电子系统使命任务各个阶段分解为功能组件,给出了一种功能组件之间跨平台信息交互的组织方法,并采用移动自组织通信的方式实现。将某任务片段中的空中图像信息传输作为模拟案例,使用OPNET软件进行仿真研究。仿真结果表明,该方法根据任务的特性设定平台之间的动态通信过程,与没有经过使命任务分解设计的对照组相比,在同等发射功率下能够有效地降低误码率。
In advanced integrated avionics system design, cross-platform communication organizations will directly reflect the mission’s mission needs. Through the functional flowchart, the various stages of mission of avionics system are decomposed into functional components, and a cross-platform information exchange method of organizing functional components is given and implemented by mobile ad-hoc communication. The aerial image information transmission in a task fragment is taken as a simulation case and the simulation study is carried out by using OPNET software. The simulation results show that this method can set the dynamic communication process between platforms according to the characteristics of tasks. Compared with the control group without the task decomposition, the proposed method can effectively reduce the bit error rate under the same transmission power.
