以根据船舶通信数据的传输要求,快速分发船舶通信数据、优化船舶通信效果为目的,提出基于DDS的船舶通信数据库云平台数据管理方法。此方法构建基于DDS的船舶通信数据库云平台,此平台存储层利用基于删冗的云平台智能化存储方法,去除冗余数据存储有效数据后,在云服务器中通过DDS数据分发模型,驱动数据QOS要求子模型,结合数据通信的服务质量要求,确定船舶通信数据库云平台中数据传输的优先级,执行船舶通信数据分发,完成船舶通信数据库云平台的数据管理。经实验测试,本文方法使用后,紧急、较急、普通3种级别的船舶通信数据分发时,通信时延均满足要求,可快速分发船舶通信数据。
In order to quickly distribute ship communication data and optimize ship communication effect according to the transmission requirements of ship communication data, the data management method of ship communication database cloud platform based on DDS is studied. This method constructs a cloud platform of ship communication database based on DDS. The storage layer of this platform, using the intelligent storage method of cloud platform based on redundancies, removes redundant data to store valid data, drives the data QOS requirement sub model in the cloud server through the DDS data distribution model, determines the priority of data transmission in the cloud platform of ship communication database, and executes ship communication data distribution in combination with the quality of service requirements of data communication. Complete the data management of the ship communication database cloud platform. After the experimental test, when the proposed method is used, the communication delay of emergency, urgent and ordinary ship communication data distribution can meet the requirements, and the ship communication data can be quickly distributed.
