基于RTX实时仿真系统的设计与实现

Design and realization of real-time simulation system based on RTX

针对windows操作系统实时性不强而实时操作系统人机交互能力较差的问题,提出一种基于Windows实时扩展技术RTX构建实时仿真系统的方法。该方法采用RTX+LabWindows/CVI混编技术实现了Windows环境下的实时仿真。经仿真验证,此系统具备仿真步长1ms的实时仿真能力。利用该方法构建的实时仿真系统既拥有很强的实时性又具备windows系统良好的人机交互能力,为今后Windows环境下实时仿真系统的构建提供了一定的依据。

The real-time property of windows Operating System is undesirable and the human-machine interaction ability of real-time Operating System is not very satisfied, a method that takes use of the real-time extension system （RTX） to construct real-time simulation system is presented. The method adopts RTX ＋ LabWindows/CVI technology to realize the real-time simulation under windows environment .Practice has proved that this system has the real-time simulation ability with lms simulation step and 50ms display update cycle. The real-time simulation system based on this method owns not only a fine real-time property but also a good human-machine interaction ability of windows Operating System, and provides the reference for the future real-time simulation system under Windows environment.
