DDS在多传感器融合系统中的应用

Application of DDS in multisensor fusion system

在多传感器融合这样的任务系统中,如何在正确的时间和地点获取正确的数据表现得尤为关键。文章基于对象管理组织(OMG)的数据分发服务标准,以发布/订阅为模型,提出了数据分发服务(DDS)在多传感器融合系统中的应用。实现了分布式环境中以数据为中心的数据实时传输,解决了服务质量约束、通信节点动态拓扑及单点失效等问题。该数据分发服务与CORBA规范和其他C-S通信模型相比,具有较好的灵活性、实时性、可扩展性和可靠性。

In such task systems as multi-sensor fusion, how to obtain the correct data representation at the right time and place is particularly critical. Based on OMG data distribution service standard and publish/subscribe model, this paper presents the application of data distribution service（DDS）in multi-sensor fusion system. The real-time data transmission based on data in distributed environment is realized,and the problems of QoS constraints, dynamic topology of communication nodes and single point failure are solved. Compared with C ORBA specification and other C-S communication models, this data distribution service has better flexibility, real-time performance, scalability and reliability.
