Research On The Proxy Technology For Joint Simulation Experiment Platform Based On Data Distribution Service

With the development of military simulation technology,single weapon system simulation becomes harder and harder to satisfy the need of the development of weapon and equipment simulation.It becomes common to conduct joint simulation experiments by integrating simulation systems distributed in different regions.This dissertation studies the communication environment support for joint simulation experiment platform and simulation management and control technology,and then discusses the key technologies of building the platform.First,the dissertation analyzed the architecture and communication needs of joint simulation experiment platform,discussed the main technologies for solving the coupling problem and complex data stream problem,analyzed the advantages of the data distribution service(DDS)as compare to the other technologies,put forward that we use DDS to support the communication among different systems in the platform,and introduced the communication model of DDS and the method for building the communication using DDS.Then,the dissertation put forward a method named ?main control + proxy? for integrating systems to manage and control the simulation.It analyzed the operating principle of a proxy,discussed the function design,class structure and operating process the proxy,and gave the concrete realization of the proxy using the example of the proxy design for weapon simulation system.At last,the dissertation built a simple system to conduct joint simulation experiments.The system integrated the main control system,weapon simulation system and guidance and control system to testify the method of building the proxy based on DDS.By analyzing the results of simulation experiments,we conclude that it is feasible to building the joint simulation experiment platform by using the proxy technology we studied in the dissertation.
