摘要
在一些仿真应用中,由于Windows操作系统较差的实时性从而给许多半物理仿真试验带来了一些不确定的因素。在充分论证的基础上,引入了Ardence公司的基于Windows的硬实时解决方案RTX,并结合某型号导弹仿真课题总结出了Windows环境下RTX实时应用系统的设计方法与开发流程以及RTX下硬件板卡驱动程序的编写,最后将这种设计方法成功应用在该型号导弹飞行仿真系统中。实验证明该仿真系统是可靠的、稳定的,整个实验过程中导弹的飞行数据没有丢失,仿真周期确定,结果正确,RTX仿真程序能够满足系统对实时性和确定性的要求。
In some simulative applications, there are uncertainties in quite a few half-hardware simulation experiments caused by poor realtime performance of the Windows Operation System . On the basis of sufficient argumentation, the author introduced RTX, a Windows based solution for hardware real-time from Ardence Inc. We concluded the designing method and developing flow of RTX real-time system in Windows environment in combination with a simulation project of a certain missile, as well as drivers programming for I/O cards in the RTX. In the end, we applied this method to the flight simulation of a certain missile successfully. The experimental result indicates that the sinnalation system is reliable and steady, and the missile flight data did not lose during the whole experiment process, the simulation period is determined and the result is correct. The RTX simulation system can satisfy the demands of the system in real-time and certainty.
