高置信度多粒度可重用通信装备仿真模型研究

In accordance with the increasing systematic, confrontational demand of the troops' training and testing under conditions of information technology, the inadequate fusion of virtual and real communication equipment in the physical logic, and the low integration of virtual simulation and live resources, targeting communication equipment simulation model to a high degree of credibility and reusability development, it is necessary to carry out research on credible, multi-granularity and reusable communication equipment simulation model. In terms of hierarchical modeling concept, communication equipment model is abstracted to four nested models, that is, platform model, device model, interface model and protocol model, which drive each other through message passing mechanism. The reusable constructing and verification techniques of communication equipment are supposed to be researched, and then the built communication equipment simulation model is applied to a typical network model, in order to analyze statistics of the whole network and the nodes. The integration of simulation system and real systems is to be explored, as well as the implementing scheme of the integration of virtual and real environment and communication equipment simulation model channel matching, and character abstraction of protocol model and structural analysis of protocol stack, which can provide technical basis for building a multi-level, system-wide, comprehensive and systematic communication equipment model. The model can be used to build flexibly called and rapidly deployed communication equipment simulation model library, which is supposed to be used to accurately assess the operational effectiveness of the communication equipment, and has an important military significance and practical demand.
