基于DDS的空间平台仿真试验床信息交互技术研究

摘要

为了研究大型复杂系统仿真平台的信息交互问题，首先针对空间平台仿真试验床的信息交互技术做了需求分析，通过分析，采用基于数据分发服务（DDS）规范对空间平台仿真试验床的信息交互技术进行了研究。建立了空间平台仿真试验床的信息交互系统体系结构，并且构造了它的全局数据空间，最终对信息交互的流程进行了规范。基于该方法的仿真试验床具有高便捷性、易集成性、高可靠性等特点，为整个仿真试验床的运行和开发打下了良好的基础。%In order to research the problem existing in information exchange for simulation platform of large-scale complex systems,the requirement analysis of information-exchange technology for simulative test-bed on space platform is conducted in this paper. The research on information-exchange technology for simulative test-bed on space platform was carried out based on specification for data distribution service(DDS). An architecture of information-exchange technology for simulative test-bed on space platform was established and its global data space was constructed. The process of information exchange was specified. Based on this method,the simulation test-bed has the features of high convenience,easy integration and high reliability. A foun-dation was made for running and developmentof the simulative test-bed on space platform.
