基于全数字总线的新一代运载火箭半实物仿真

摘要

提出基于1553B全数字总线的新一代运载火箭半实物仿真系统的总体方案,地面仿真设备通过共享内存实时网络相连,具有较好的实时性、可靠性、通用性.通过对于仿真机和共享内存实时网卡优缺点的介绍,为试验系统设备选型提供了参考.介绍了总线监控软件的设计思想和总线信号解析的原理.最后对仿真系统进行了评价.%The paper puts forward a new project based on the MIL - STD -1553B bus and real - time network of hardware - in - the - loop simulation system of the new generation of launch vehicle. The equipment of the simulation system can be connected to the real - time network, which is real - time, reliability and versatility. This paper introduces some kinds of the simulation computers and the real -time network equipments, which offer the reference for the selection of the hardware of the simulation system. In addition, this paper also introduces a method for designing BM software. Finally an opinion of the hardware - in - the - loop simulation system is offered.
