Construction And Application Research On The Navigation Support Wireless Communication Network Of The Yangtze River Estuary

The Yangtze estuary water area is the most important water transport channel of the Yangtze Shanghai section,is the key service waters of the east China sea maritime security center.With the continuous development of shipping industry in our country and deepening construction of Shanghai international shipping center,Shanghai maritime security work is under unprecedented opportunities and challenges,water safety supervision situation put forward higher requirements for maritime security ability.At the same time,the maritime security development turns to pay more attention to sophisticated management,development quality,service level enhancement,solution of deepseated and overall problem.In order to effectively alleviate the contradiction between the increasing water safety supervision and external service pressure and the relative shortage of resources,to meet the requirements of scientific development of navigation security and improve the level of service,it urgently need to strengthen the information construction,optimize the resources allocation,introduce advanced technology to maritime security services,raise the efficiency of internal maritime supervision and external overall service.The network application situation of Yangtze estuary water area is an urgent need maritime security department to use the third generation,fourth generation network technology,under the guidance of maritime safety information in the top design,based on social resources,to construct Yangtze estuary waters maritime security wireless communication network,build the water information highway of Yangtze river estuary waters,service the service deployment and administration and law enforcement of maritime service administration,and at the same time,it can also follow the example of Europe and the United States and other advanced countries’ experience,in the service of ship-to-shore communications,goods logistics transportation,coastal ports,multimodal transport,etc.,embodying more economic and social value in addition to the simple communication function in the process of servicing shipping and logistics,effectively improving the waters maritime security capacity,improving service image of navigation security department.Based on the analysis of practical application communication technologies of existing Shanghai Maritime Bureau maritime business systems and their advantages and disadvantages,combined with the requirements of "the maritime system top design",the technical requirementsof navigation support wireless communication network of Yangtze River Estuary are described.And in accordance with the actual marine business needs,the basic businesses and business priority that must carried by wireless network are defined.Meanwhile,it introduces the results of repeated attempts and visit and study of navigation support wireless communication network of Yangtze River Estuary,and starts from the actual effect,compares the existing advantages and disadvantages in the using of several technologies,and shows the significant superiority of TD-LTE technology.Finally,it introduces the technical characteristics and network construction principles of TD-LTE system,as the finally technical route of navigation support wireless communication network construction of Yangtze River Estuary.Meanwhile,according to the specific index of network bandwidth of various maritime business supported by maritime support,network planning simulation results are given,and it proves that meet business needs.
