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(Real-Time eXtension),并结合某型号飞行器仿真课题总结出了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某型号飞行器飞行仿真系统中。实验证明该仿真系统是可靠的、稳定的,整个实验过程中飞行器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 simulation applications, many semi physical simulation have some uncertain factors based on Windows operating system due to its poor real-time performance. Through on the sufficient demonstration,Real-Time eXtension （RTX） developed by Ardence Company can be used to resolve the real-time performance. Combined with a certain type aircraft simulation project, the article finds a solution of RTX real-time application system design method and development process in Windows. Also the programming method of hardware Drivers is solved on RTX. Now this kind of design method has been successfully applied in a certain type of aircraft flight simulation system. A series of experiments show that the simulation system is reliable, stable. The aircraft flight data doesn＇ t lost and simulation result is correct in the whole experiment process. RTX simulation program can satisfy the system requirements for real-time and certainty
