Design and Implementation of Electronic Instrument Simulation System for Civil Aircraft

在基于PC机的网络环境中,通过VAPS开发工具作为平台,利用C语言和网络通信技术,设计了一套民用飞机座舱主要电子显示仪表的仿真系统。基于模块化结构和事件触发驱动的设计思想,阐述了电子显示仪表仿真的功能单元及工作原理,讨论了系统实现中的仪表逻辑连接、坐标变换模型及数据通讯等若干关键技术。仿真结果表明,该系统逼真地演示出民机电子仪表工作过程,并且满足系统仿真的实时性要求,具有很强的工程实用性和通用性。

Using C language and network communication, an electronic instrument simulation system of civil aircraft is developed with VAPS in PC network plaffortm. The function units and working principle of simulation system are expatiated based on modularized structure and event triggering mechanism. Some key techniques such as logistic connection of instrument, coordinate transformation model and data communication are discussed. The simulation results show that this system can realistically demonstrate the working process of flight electronic instrument and meet the real time requirement, so it has good validity and practicability in simulation engineering.
