Research on Virtual NC System Based on Windows NT & RTX

Fcousing on real-time and reliability of information service,a simulation system architecture and its implementation method based on Windows NT+RTX were put forward to improve the running efficiency of simulation system under the complex distributing and heterogeneous network environment.In this architecture,the real-time simulation ethernet using RT-TCP and RT-UDP was used to establish semi-physical access network based on broadcasting memory network.At the same time,to meet the need of real-time of simulation information,testing database based on RTX memory database was designed to support information management.Test and analysis results show that the simulation platform possesses better reliability and extensible performances,and meets the requirements of real-time for the complex simulation system.
