Research on the Real-time Network Application of Hardware-in-the-loop Simulation of Launch Vehicle Control System

针对新一代运载火箭组合化、系统化、通用化的特点,必须在现有的运载火箭控制系统半实物仿真试验的基础上,建立新型的运载火箭控制系统分布式半实物仿真系统,实现仿真设备的组合化、功能的多样化。本文从系统总体角度出发,对运载火箭半实物仿真试验实时网络设备进行深入分析和科学选型,同时对其接口软件进行设计,以提供实时网络各节点之间高效、方便的通信接口。最终设计出比较完备的运载火箭半实物仿真试验实时网络集成方案,确保各种仿真设备能够连成一个有机整体,形成仿真试验能力。

A new kind of distributed hardware-in-the-loop simulation system for the new generation of launch vehicle should be established based on the existing system of launch vehicle. This paper not only goes into deeply but also selects scientifically the real-time network equipments of hardware-in-the-loop simulation of launch vehicle control system with systemic point of view. And synchronously the interface software is designed for providing the efficient and convenient communication which is among each node of the real-time network. Finally, a compositive scheme of the real-time network of hardware-in-the-loop simulation is offered, so that each kind of simulation equipments can be well connected to an organic whole, which have the ability of hardware-in-the-loop simulation.
