针对某型滑翔航弹研制中半实物仿真实验的实时性需求,基于工业控制计算机Windows操作系统和PCI定时板卡,采用调用外部时钟、内存动态分配和多线程技术,设计并实现了最小仿真步长为1ms的半实物实时仿真软件。以滑翔航弹弹道初始条件为输入信息,对软件进行了测试,结果表明:该软件的单步事务处理实际耗时严格小于1ms,均值为0.53ms,满足滑翔航弹半实物实时仿真的需要。
In order to meet the real-time requirement of semi-physical simulation experiment in developing a gliding missile, based on industrial control computer Windows operating system and PCI timing board, a minimum simulation step is designed and implemented by calling external clock, memory dynamic allocation and multi-thread technology Length of 1ms semi-physical real-time simulation software. Based on the initial information of gliding bomb trajectory, the software is tested. The results show that the single-step transaction processing time of this software is strictly less than 1 ms, with a mean of 0.53ms, which meets the need of semi-real gliding missile real-time simulation.
