船舶信息系统数据分发服务研究

摘要

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.%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。
