Research On Key Technologies Of Synthetic Simulation Test Environment For Weapon System Of Systems

The effectiveness of single weapon system needs to be accessed according to the performance of the whole system of systems(SoS). Simultaneously, the evaluation and optimization study on weapon SoS relies on valid data derived from weapon systems at lower levels. Therefore, the joint simulation of engineering and engagement-level possesses great significance, in which high-resolution models supported by engineeringlevel systems are incorporated in engagement-level, and enables weapon SoS performance evaluation with significantly higher credibility. The typical realization is Weapon & Weapon SoS Multi-level Simulation Support Environment, and in this thesis we call it Weapon SoS Synthetic Simulation Test Environment(SSTE). Due to the participation of Hardware in the Loop Systems at engineering-level simulation, SSTE is actually an integration of distributed, heterogeneous and critical real-time systems. This thesis mainly discussed some key technologies that are utilized in constructing SSTE, which include distributed and heterogeneous systems interoperation, critical time constraints satisfaction and experiment management and control.To begin with, this thesis analyzed detailed characteristics of SSTE, as well as its construction principles. Some common technologies are researched, and a Mastercontrol + Sub-control pattern is proposed to serve as SSTE’s architecture. And then the pattern’s advantages are discussed in terms of its support for interoperability, real-time performance and scalability. Main problems that need to be addressed under this architecture are analyzed.Then this thesis takes a complete study on two key issues: the temporal consistency and communication infrastructure. The principal solution of temporal consistency in a joint simulation can be divided as time synchronization and network delay compensation. This thesis proposed a GPS-based approach combined with Windows + RTX software to resolve the time synchronization problems, and designed network delay compensation strategies specific to SSTE, in order to make the solution adaptive to subsystems with different time granularities. As with communication infrastructure, the general data distribution requirements are discussed at first. Then a mechanism complaint to Data Distribution Service(DDS) Specification is designed. Based on that, this thesis performs detailed classification and organization for complex data flows in SSTE, and defined proper QoS implementation strategy.At last, taking the Air-defense Missile SoS Simulation Experiment Management & Control Platform Project as an example, this thesis showed the application of the hierarchical structure proposed here, as well as the prototype design and implementation. The management, schedule and control strategies are emphasized in this case study. Conclusions stated that key technologies studied in this thesis could well satisfy the SSTE’s construction requirements.
