无线网络在船舶跨区域数据整合平台中的应用

Application of wireless network in ship cross-area data integration platform

为实现船舶跨区域数据的共享,提升船舶统一管理服务水平和船舶运行效率,研究基于无线网络的船舶跨区域数据整合平台。平台通过感知层采集船舶航行数据,在经过网络层全功能控制器的作用下,通过基于信道负载的网络跨层,分配网络带宽,传送跨区域数据至数据层;数据层接收该数据后,采用基于信息熵算法聚类该数据,并存储至数据中心;应用层依据船舶管理需求,调用数据中心数据,实现船舶全面、综合管理,并通过展示层呈现管理结果。测试结果显示:该平台的网络通信质量良好,接收信号强度结果均在-40 dBm以上,最大值为-18 dBm左右;聚类效果良好,保证数据聚类的可靠性,为船舶的综合管理提供全面、综合数据依据。

In order to realize the sharing of ship trans-regional data,improve ship unified management service level and ship operation efficiency,a ship trans-regional data integration platform based on wireless network is researched.The platform collects ship navigation data through the perception layer,and distributes network bandwidth and transmits trans-regional data to the data layer through the cross-layer design based on channel load under the control of the full-function controller at the network layer.After receiving the data,the data layer uses the information entropy algorithm to cluster the data and stores it to the data center.According to ship management requirements,the application layer invokes data center data to realize ship comprehensive and comprehensive management,and presents management results through the display layer.The test results show that the network communication quality of the platform is good,the received signal intensity results are above-40 dbm,the maximum is about-18 dBm.Good clustering effect ensures the reliability of data clustering,it provides comprehensive and comprehensive data basis for ship comprehensive management.
