基于DDS舰载火控系统通信

摘要

针对舰载火控系统通信需求，提出基于DDS的舰载火控体系结构，实现了系统松耦合，同时满足了实时性要求。通过发布订阅服务的设计，基于默认QoS策略，分别使用内置数据类型和自定义数据类型实现舰载火控系统的发布订阅功能。通过可靠性QoS策略的配置分析其对系统实时性和可靠性的影响。测试结果表明，DDS在舰载火控系统中有广阔的应用前景。%Ship fire control structure based on DDS is proposed according to the need of communication of ship fire control system. The system is loosely⁃coupled and the real⁃time requirement is satisfied. By the design of publish and subscribe serv⁃ices,built⁃in and user⁃defined data types are both used to disseminate data based on default QoS policies. By configuring the reliability QoS policy,its effect on the reliability and real⁃time capabilities of the system is illustrated. The result of simulation proves that DDS can be furtherly used in ship fire control system.
