| 摘 要： | 复杂实时仿真系统中不同层次对实时性、可靠性要求各不相同;网络和操作系统是该类系统环境的重要组成部分;针对硬件在回路试验的实时需求,提出了基于RTX下的反射内存网的半实物接入网络,构建了基于RT-TCP/IP的虚拟试验局域网;其操作系统层面,设计为弱实时任务在Windows内核上运行,而强实时任务分布在RTX内核之上;文中对各层面的实时性进行了测试,分析了层面间的实时性约束;结合某飞行试验系统的虚拟试验,给出了具体的设计方案,满足了应用中不同实时性的要求。

| Abstract: | Different layers in complex real-time testing system have different requirements on real-time and reliability.The networks and operation systems are the major components of such frames.The operation system is designed to run processes with weak real-time within the kernel of Windows and the processes with strong real-time within kernel of RTX.A virtual testing Ethernet based on RT-TCP/IP is built.A semi-entity network based on RTX reflective memory network is realized to meet the real-time requirement in lo... |
