基于使命任务分解的航空电子跨平台通信组织与仿真

Organization and simulation of cross-platform communication of avionics based on mission decomposition

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 design, cross-platform communication organization directly reflects the mission demand. After decomposing the mission tasks into functional components by Function Flow Block Diagram, we present a organizational method of cross-platform communication for functional components, and realize it by the mobile sel f-organized network communication mode. We set a case, a mission fragment in which image information transmission is needed, and simulate the communication by OPNET software. The result shows that, the given method can set dynamic communication process between platforms according to the specific mission fragments, and compared with the control simulation not based on the mission decomposition, in the same transmit power condition, the bit error rate of the receiver can be reduced effectively.
