摘要
虚拟试验是近年来兴起的一门技术,在国外已得到大量应用,国内的研究和应用才刚刚起步,尚没有统一的权威的定义。在Windows平台上实现实时任务处理也是工程实践的难点之一。文中以某武器部件虚拟试验系统为背景,探究了虚拟试验系统的概念,分析了虚拟试验系统的实时性需求。介绍了VMIC反射内存网和RTX的基本原理及其在实时系统中的应用。提出的实时性和可靠性的解决方案已成功应用于工程实践中。提出的基于反射内存网和RTX的虚拟试验系统结构是面向军工武器系统虚拟试验的一个较好的解决方案。
Virtual test is a new technology rising in recent years,which is already widely applied in developed countries but just on the scratch in China.There isn＇t a uniform and canonical definition for virtual test.It is a serous problem to process real-time tasks on Windows platform in engineering practice.The paper discusses the concept of virtual test,analyses the real-time requirement of virtual test system.It also introduces VMIC reflective memory network and RTX and their application in real time system.The resolution of real-time and reliability proposed in the paper is successfully used into practice.The distributed virtual test system architecture based on reflective memory network and RTX proposed in the paper will be a good solution for military weapon system oriented virtual test.
