摘　　要：对对象管理组织(OMG)颁布的数据分发服务(DDS)进行介绍,分析DDS的基本原理、工作流程和通信模式,重点分析RTI-DDS的可靠通信模式,然后以无人机地面站系统为例,分析大型分布式系统面临的数据通信问题,然后以解决大型分布式综合系统数据通信为目的对RTI-DDS的通信性能进行系统验证,最终得出结论,使用RTI-DDS可以满足无人机地面站系统通信网络的性能要求,具有很好的实用价值。Introduces the data distribution service specification, which is defined by Object Management Group. Analyzes the fundamental theory,flow of work, communication model of DDS. It is the key point to analyze the reliable communication model of RTI-DDS. Takes UAV ＇s ground controlling system（GCS） as an example, analyzes about data communication problems of large-scale distributed system. And then takes aim at solving data communication problems of large-scale distributed system, do experiments to test and prove the communication performance of RTI-DDS. It is proved that the requires can be satisfied by using RTI-DDS to solve data communication problems of dis-tributed system, and it is practical.
