摘　　要：为实现仿真系统中各仿真设备之间实时的数据通讯,文章设计并实现了一种基于LabVIEW RT以及反射内存网络的数据实时采集及传输系统;通过深入研究反射内存网络集线器的内部结构,确立了系统合适的网络分布结构,从硬件上保证了系统的实时性;在深入研究LabVIEW RT环境下反射内存的驱动运行原理后,实现了在RT环境下对反射内存的应用;并通过编程中对驱动函数合适的选择应用,优化了系统软件的实时性能;测试及实践证明,系统性能良好,在实际仿真中发挥了作用。For the real-time data communication between facilities of the distributed simulation system, a data real-time acquisition and trans- mission system based on reflective memory （RM） and LabVIEW RT programming was designed and realized. Having carefully studied the inner structure of the assembly of RM network, system＇s network structure was ascertained with considerations of enhancing the real-time performance of the system. And with the working principles of the RM＇s driver researched, the paper realized the application of RM in LabVIEW RT. And when programming, the functions of driver was sensitively chosen into application, hence the real-time performance was in further supported. The system, proved by testing and the actual application, has worked well and played a certain positive role in simulation systems.
