摘　　要：针对联合式航电系统原理仿真及教学需求,设计并实现了基于实体座舱并嵌入DCS数字战斗模拟软件的全数字仿真系统。系统可模拟航电系统地面准备、导航、空空、空地模式下的操作控制逻辑和显示画面;实体座舱和数字战斗模拟软件通过多路RS422总线和HDMI接口实现信息交互;采用共享内存机制获取飞行状态及航电终端仿真数据作为激励源,模拟航电系统运行过程中各个子系统之间GJB 289A总线的信息流,展示GJB 289A总线通信原理及调度机制。实践证明,系统能有效支撑航空电子综合技术与原理的教学。Aiming at the requirements of principle teaching and practical training of the joint avionics system,a full digital simulation system including a real analog cockpit embedded in DCS digital battle simulation software is designed and implemented.The system can simulate the work flow and display control pictures of avionics system in ground preparation,navigation,air to air and air to ground modes.The physical simulation of the cockpit and the digital combat simulation system realize information interaction through multiple RS422 buses and HDMI interfaces.The shared memory is used to obtain flight status and avionics terminal simulation data as the excitation source of the GJB 289A bus communication system,which can simulate the information flow between subsystems during the operation of the avionics system,and demonstrate the GJB 289A bus communication principle and scheduling mechanism.Practice has proved that the application of this platform can effectively support the teaching of integrated avionics technology and principle.
