Abstract: Aiming at the shortcomings of present ship automatic navigation systems,this paper designs an integrated bridge information system that accords with the technical development trend of ship automatic navigation system.The system equipments are linked in integrated network by communication gateway with ARM chip.Distributed database technology is studied,the function of Oracle Advanced Replication is utilized to implement dual-backup.Information fusion technology can solve the information overloading issue and enhance the accuracy and reliability of information,so a navigation information fusion model based on federated filtering is proposed.The results of corresponding experiments indicate that the integrated bridge information system has practical value.

Key words: integrated bridge, network, distributed database, information fusion

摘要: 针对船舶自动航行系统现有技术的不足之处,设计了符合船舶自动航行技术发展方向的综合船桥信息处理系统。制作了以ARM芯片为核心的通信网关,实现了信息系统的一体化网络连接;研究了分布式数据库技术,并且运用Oracle数据库的Advanced Replication功能实现信息系统的双机热备;采用信息融合技术可解决系统的信息过载问题,并提高信息精度和可靠性,给出了基于联邦滤波器的导航信息融合模型。相关的测试与实验证明该系统具备实用价值。
