| The data collection and state analysis of ships in navigation are the basis to ensure the smooth implementation of the information and intelligence of shipping.Because the massive multi-source heterogeneous data produced by many marine equipments and systems can not be collected and analyzed in real-time,shipping enterprises can not make effective decision and result in loss;At the same time,the information island phenomenon is serious,especially the large quantity and wide area inland river old ships,its digitization level is low.Aiming at the above problems,this paper studies the real-time collection of ship data,the integration of ship-side digital system,the compression and transmission of key data and the analysis of ship state in cloud,based on the cloud service platform,this paper proposes a set of solutions for the information collection and state analysis of Inland River vessels,and studies the key technologies involved,to realize the analysis of ship running status and provide personalized data service for customers.Firstly,this paper expounds the inevitable trend of ship informatization and intelligentization and the challenges faced by the ship industry at present,and analyzes the characteristics of the ship operation data and the problems of ship informatization,aiming at the multi-source Heterogeneity of the field data information and the application requirements,a technical framework for the collection of information and the analysis of the running state of the in-navigation ships is proposed,and a method for the rapid information transformation of the large-scale old ships is explored,resource sharing is realized by providing data service for users through cloud platform.Then,according to the key technologies involved in the framework,the research of the technical scheme is carried out from the aspects of structure,principle and function,etc.,it mainly includes: real-time data acquisition of in-flight ship based on different protocol interfaces,semantic integration of ship Operation Information Based on dynamic adaptation,low bandwidth related data compression and transmission,in-flight ship information integration based on Web Service and in-flight ship state analysis based on cloud platform,analyze the problems that need to be solved in each implementation and come up with a set of solutions.Finally,on the basis of the theory and technology of the framework,the paper proves the feasibility of the solution by using cloud platform to validate the prototype of the key technologies,it provides the basic platform,data resource and analysis method for the information transformation of the old ships in inland waters and the application of big data analysis and intelligence in the future ship industry. |
