Real-time Distributed Simulation Platform For Heterogeneous System Integration Technology Research

This thesis is focus on integration technology of heterogenous distributed system of simulation, based on the demand of Hardware In the Loop Simulation (HILS) of war industry.This paper has researched mainly key integration technology in heterogenous distributed system of Simulation, including the framework of integration of heterogenous distributed system of Simulation, and distributed middleware, in detailed as follows: .(1) After analysed the features and demands of heterogenous distributed system, includeing distributed operating systems and distributed middleware, we bring forword achieve the interaton of heterogenous distributed system of simulation with the virtual Share Memory middleware.(2) It also studyed the features and demands of real time of heterogenous distributed system of simulation, and the characteristic of network that tampered with the real-time of sysytem.(3) We discussed and analyzed the requirement of real time distributed Simulation, and then we developed the Virtual Share Memory middleware based on heterogenous Broadcast Memory Network.(4) Researched the methods of network interface of virtual distributed share memory middleware in specific flat, and achieve these methods in OS IRIX. At last, compared the performance of these methods.(5) This paper has developed the demo software of heterogenous real-time and distributed simulation with the Virtual Share Memory middleware.
