某直升机综合航电显控仿真系统的开发与实现

摘要

This paper discusses the design of hardware and software of an integrated avionics simulation system based on a helicopter s bus topological structure. This paper focuses on the modularization of display, control and communication.The system simulates not only the logic of the Pilot Operation Procedure but also the communication of MIL-STD-1553 databus and ARINC429 databus in real-time.The system realizes the intercommunion of the Radar, navigation equipment , atmosphere equipment and integrated displays by emulation mode.It is showed that the system 's structure is rational and the function and the capabilties can serve for the refit requirements.%根据某直升机改装大型综合航电显控系统的需求,依据其拓扑结构,进行了仿真系统的硬件和软件设计,重点论述了基于模块化的显示、控制及通讯软件设计,按照实时性要求,仿真POP操作逻辑及MIL-STD-1553和ARINC429航空总线通讯,实现了仿真直升机上雷达、惯导、大气机通过综合处理计算机与综合显示器之间的交联,结果表明该仿真系统结构合理,功能及性能满足直升机改装验证的要求.
