Multi-threaded Hardware-in-loop Simulation Method Based on RTX

针对现有弹道修正引信半实物仿真系统实时性缺陷,提出了基于系统实时性扩展的多线程半实物仿真方法。该方法首先利用实时性扩展技术为仿真数据实时发送及解算模块构建了独立的实时进程,其次利用多线程技术对原有弹道修正半实物仿真系统任务进行重新划分,最后利用共享内存来实现进程间的数据交换。仿真结果表明:系统实时性得到有效改善,确保了操作系统对仿真关键环节的实时响应,同时满足了功能需求。

The existing trajectory correction fuze hardware-in-loop simulation platform was of low real-time property. To solve the problem, a multi-threaded hardware-in-loop simulation method based on RTX was pro- posed. This method used RTX to construct an independent real-time process {or real-time transmission and bal- listic solution, and then, multi-threaded method was used to optimize thread partition to ensure the real-time re- sponse of operating system to the key links . Simulation results showed that the new method could effectively improve the real-time of the simulation system and meet the functional requirement.
