The Real Time Simulation System Based on Fiber Optics Networks

主要介绍了一种基于光纤网的实时仿真系统,该系统采用广播内存网络体系结构,克服了一般的以太网络环境中存在通信延迟和有限带宽等缺点,结构简单,实时性好。该系统采用全数字方式进行飞机动力学、运动学特性及传感器的仿真,具有全程轨迹显示功能,可以直观地反映待测飞控系统对外回路的控制性能。实验表明该仿真系统的性能良好,完全满足飞控系统仿真实验的要求。

This paper deseribes a real time simulation system based on fiber optics networks, in this project we use hmadcast memory networks frameword, overeome the shortcomings of delay in transmission and finite bandwidth in ethernet networks, the framework of this system is simple and rite real time characteristic is good. The characteristic of the plane dynamics and kinematics, sensors are simulated by distal computer, the full track of the fly is displayed, which is convenient for militating the performance of flight control system （FCS） of outer loop, the test indicates that the performance index of this real time simulation system fulfils the simulation teal of the flight control system.
