基于有限状态机的航电显控系统仿真

Simulation of Avionics Display and Control Management System Based on FSM

针对当前飞行训练模拟器中航电系统显控逻辑仿真软件开发困难、可维护性差的问题,提出一种将显控逻辑判断与显示画面仿真独立设计的模块化、松耦合的显控系统功能仿真思路。根据显控系统交互式、多输入多输出的时序逻辑决策特点,基于有限状态机(finite state machine,FSM)理论构建显控逻辑仿真模块,并应用Simulink/Stateflow进行实现。结果表明:该设计思路结构合理,开发过程直观,程序可维护性、可移植性强,有利于提高显控逻辑仿真度和开发效率。

In order to solve the problems of difficult development and poor maintainability of display and control logic simulation software of avionics system in current flight training simulator,a modular and loosely coupled display and control system function simulation idea is proposed,in which the display and control logic judgment and display picture simulation are designed independently.The display and control logic simulation module is constructed based on the finite state machine(FSM)theory according to the interactive,multiple input and multiple output temporal logic decision-making characteristics of the display and control system,and is implemented by Simulink/Stateflow.The results show that the design idea and structure are reasonable,the development process is intuitive,and the program is easy to maintain and transplant,which is conducive to improving the display and control logic simulation and development efficiency.
