Research On Multi Source And Dynamic Information Service Technology Of Intelligent Ship

This paper studies the multi-source and dynamic information service technology of intelligent ship in order to solve the problem of multi-source heterogeneous data integration and multi-source and dynamic information service model of intelligent ship.On the basis of solving these two problems,this paper proposes a multi-source dynamic information service system based on ship 's multi-source data integration and private cloud platform.This article has done the following on this topic:Firstly,this paper analyzes the composition and characteristics of multi-source information of intelligent ships,and the problems of multi-source dynamic information service of intelligent ships under the current conditions.On this basis,the theory of multi-source data integration technology and cloud computing service technology related to multi-source dynamic information service of intelligent ship are studied.Secondly,based on the detailed study of various multi-source heterogeneous data integration methods,this paper establishes the corresponding mathematical model to analyze the relational model and XML Schema of the relational database,and designs and implements a method of transforming the relational schema into XML Schema data conversion algorithm,and based on this algorithm to design a multi-source heterogeneous data integration platform for the subsequent intelligent ship multi-source dynamic information service technology to provide a data support.Thirdly,on the basis of the ship multi-source data integration platform,the paper studies the dynamic information service technology of the ship,and puts forward the re-integration of the existing hardware and software resources to establish the intelligent ship information service model based on the private cloud.Combined with the characteristics of intelligent ship information service,a kind of point-to-point information push service is proposed for user's needs.Finally,the OpenStack open source project is used to build the private cloud computing platform and test the performance of the private cloud service platform.It is proved that compared with the traditional ship information service mode,the private cloud platform can effectively improve the efficiency of resource utilization under the premise of ensuring the quality of information service.Finally,the integrated ship multi-source heterogeneous data integration platform and the ship dynamic information cloud service mode to complete the intelligent ship multi-source dynamic information service system overall structure design.Then,the chart software,marine environment software and AIS dynamic information service software are deployed to the private cloud platform built in this paper,and a simple multi-source dynamic information service system is realized to verify the multi-source dynamic information service system The feasibility of the.
