Design of Distributed Real-time Simulation System Based on RTX and Reflective Memory Network

The hardware in the-loop simulation is an important method to speed up the research process of spacecraft, and the real time simulation system is the core of the hardware in the loop simulation. Distributed real-time simulation system based on RTX and reflective memory network is upgrading and expansion from the EMES simulation system, mainly expansion on the simulation calculation, simulation scheduling and network communication, and design the real time scheduling algorithm based on RTX high precision timer and communication protocol based on reflective memory network, the simulation system using dual network transmission technology. At last, the experimental results show that, the system is real-time, and the communication is stable, high speed and reliable, and the simulation system meets the requirements of real-time simulation.
