Research On Simulation Technology Of Cluster Data Link Network Based On DDS

In order to assess the comprehensive effectiveness of helicopter fleet operations in complex battlefield environments,it is necessary to simulate the airborne data chain system to verify the performance and reliability of the data chain system work.The data chain network is the core to realize the informational and intelligence of warfare,which makes the independent single-platform combat become joint overall combat.Thus it can improve the combat capability.The airborne data chain simulation system constructs the data chain simulation environment.It also uses the data and indicators as the research carrier to study the helicopter group combat situation under various application scenarios according to the data chain simulation model.The system designs the airborne tactical data chain simulation system,in order to analyze the impact on operational effectiveness by designing a fleet tactical data chain simulation system.This paper firstly constructs a decentralized distributed data distribution service（DDS）theoretical model by studying the requirements of air swarm tactical data chain simulation system.It defines the structure of relevant components of the model,proposing a publish/subscribe based air swarm tactical data chain simulation interaction interface specification.It also designs the data topic structure of each simulation node.On this basis,the framework model of DDS-based air fleet combat simulation system is constructed,which mainly includes data chain protocol simulation,communication failure simulation and real-time information interaction functions.In the data chain protocol simulation module,the time slot allocation algorithm and conflict detection strategy based on hierarchical fleet formation are proposed.The DDS-based fleet data chain simulation system is finally realized.It provides a reliable quantitative basis for the evaluation of helicopter combat performance.And it effectively supports the evaluation of tactical data chain combat effectiveness in system simulation under information technology conditions.
