Software Design for Comprehensive Control Platform of a Missile Simulation System Based on RTX

The comprehensive control platform of a simulator is the control center of a hardware in the loop simulation system, whose key technologies are timing precision and timing data synchronization. This paper achieves the precise timing using the high-precision timer under a real-time extension (RTX) system, designs the driving program of VMIC card under the RTX system, studies the data synchronization algorithm, its flow chart and the method for designing the software of the comprehensive control platform. The study results indicate preliminarily that the hardware in the loop simulation system can achieve precise timing, does not produce erroneous frames or lose any frames, ensures its synchronization of data transmission and thus is worth applying to the development of a missile weapon system.
