摘　　要：针对基于传统架构的多链集成系统存在着扩展性不高、异构链间数据转换效率低、冗余度大、链间消息过滤器工作繁琐等不足之处,将数据分发服务引入到多链集成的系统架构中,形成了一种扩展方案。用数据分发服务作为多链集成系统中各个模块间的交互手段,有效地增强了多链集成系统的可扩展性,提高了链间数据转换的效率,降低了系统的冗余度,减少了链间消息过滤器的工作量。此方案已经在某多链仿真系统中得到了成功的应用。Multi Datalink Integration system based on traditional architecture has some deficiencies, such as expansibility is not high, efficiency of message conversion between different links is low, redundant and the workload of message filter is very large. the DDS technology is introduced into multi datalink integration system, a kind of expansion solution is formed. This solution uses DDS as the intercourse means between components, expansibility and efficiency of message conversion between different links is improved effectively, the system redundancy and the workload of message filter is reduced. This solution has been applied to a emulational multi datalink integration system.
