船联网的异构网络信号变换及其预测技术研究

Research on heterogeneous network signal transformation and prediction technology of ship network

船舶在海上航行时,与其他船舶及基站的通信方式以无线通信为主,其中,VHF超高频无线通信的通信效果最好,应用也最为广泛。与此同时,VHF通信也存在着一定的问题,包括通信带宽相对较窄,同一时间段可传递的数据量难以满足日益增长的通信需求等。船联网是一种基于无线通信模式的新型通信网络,充分结合了物联网技术,对实现海上航运智能化、人性化等有重要的作用。本文以船联网为研究对象,重点介绍了船联网中的异构网络信号变换技术和信号预测技术,对改善船联网的通信能力有重要意义。

When the ship is at sea, the way of communication with other ships and base stations is mainly wireless communication. The VHF UHF radio communication has the best communication effect and the most widely applied. However,there are still some problems in VHF communication, including the relatively narrow communication bandwidth, and the amount of data that can be transmitted in the same time period is difficult to meet the growing demand for communication.Ship networking is a new communication network based on wireless communication mode. It fully combines the technology of Internet of things, and plays an important role in realizing the intellectualization and humanization of marine shipping.Taking the ship networking as the research object, this paper mainly introduces the signal transformation technology and signal prediction technology of heterogeneous network in ship networking, which is of great significance for improving the communication ability of ship networking.
