火箭发射分布式仿真系统中信息交互方式设计

Design of Communication Alternation in Distributed System for Rocket Launch

回顾了分布式仿真系统中交互协议的发展,在此基础上深入研究了四种应用最广泛的数据交互方式,结合工程实践对其在分布式系统中的优缺点进行了总结。针对火箭发射分布式仿真系统实用、高效的数据通讯的需要,选择了HLA和串行通讯相结合作为信息交互方式。重点研究了多线程串行实时通信的方法。系统运行证明在设计分布式系统信息交互方式时,针对实际灵活地选择合适的交互协议,是完全可以满足设计要求的。

The development of the communication alternation protocol in distributed simulation system was looked back. Four fashions applied widely were researched, and the characteristics of them were summed up. Aiming at requirements of practicality and efficiency of communication alternation in distributed simulation system for rocket launch, the HLA and serial communication protocols were selected as the main fashion. The multithreading serial communication technology was researched specially. The working of system proves that it can satisfy the design requirements through selects alternation fashion neatly according to the project practice.
