为解决航空电子组件仿真模型故障注入效率低下的问题,提出一种基于Mealy机的航空电子组件仿真模型建模方法。该方法通过状态转移函数和输出函数分别表达出航空电子组件输入信号与组件状态、输入信号与组件输出之间的关系,可以方便地在现有模型基础上增加故障状态的同时减少建模的工作量,快速有效地建立航空电子组件虚拟维修仿真模型。将该仿真模型应用于A320虚拟维修训练器ECB组件建模中,该建模方法比同类方法减少41.4%建模时间,证明该建模方法有效。

In order to solve the inefficiency of fault injection in avionics component simulation model,a modeling method for avionics component simulation model based on Mealy machine is proposed.The relationship between the input signal of the avionics components and the state of the avionics components and the relationship between the input signal and the output of the avionics components are expressed respectively via the method,which can not only make it easy to reduce the workload of modeling while increasing the fault states,but also establish a virtual maintenance simulation model for avionics components quickly and effectively.The simulation model is applied to the modeling of the ECB components of the A320 virtual maintenance trainer and the modeling time is reduced by 41.4%when comparing this modeling method with similar methods,proving that the modeling method is effective.
