Abstract: Aiming at the problem of high real-time data demands for ship information systems, this paper applies Data Distribution Service(DDS) for ship information systems, combining with the characteristics of the ship information system, the paper proposes a communication mechanism based on interest filtering. The mechanism can express the interest of subscription more fine-grained to improve communication rate. Simulation experimental results show that the mechanism can meet loose coupling and high real-time demands, and improve the efficiency of communication.

Key words: ship information system, Data Distribution Service(DDS), middleware, publish/subscribe, interest filtering, system integration

摘要: 船舶信息系统日益复杂,其对实时性的要求也越来越高。基于此,将数据分发服务应用到船舶信息系统中,根据船舶信息系统的特点,提出一种基于兴趣过滤的通信机制,以使订阅者能够更细粒度地表达其订阅兴趣,从而提高通信效率。模拟实验结果表明,该机制能满足船舶信息系统松耦合、高实时性等要求,可有效提高数据分发效率。
