在建立飞机维修仿真中的系统模型时,针对飞机系统中航线可更换组件(LRU)之间的逻辑关系难以表达并伴随多余度系统的问题,提出一种基于扩展可达矩阵的系统建模方法,并通过组件AGENT化的方法,表达了组件在系统中的逻辑和组件状态改变对系统工作逻辑的影响。该方法能抽象飞机系统逻辑,并转化为计算机可实现的对象。通过分析可达矩阵,可明确信号传递与受维修行为所关联的组件。最后,通过构建自动飞行系统(AFS)的逻辑功能模型验证了该方法的可行性。
In the establishment of the system model of aircraft maintenance simulation, aiming at the problem that the logical relationship between the line replaceable units (LRU) in the aircraft system is difficult to express and accompanied by the redundant system, a system modeling method based on extended reachability matrix , And through the method of component AGENT, expresses the influence of component logic in the system and component state change on the system working logic. This method abstracts the logic of the aircraft system and transforms it into a computer-implementable object. By analyzing the reachability matrix, you can identify the components that are associated with the signal transmission and maintenance behavior. Finally, the feasibility of this method is verified by constructing the logical functional model of AFS.
